Software FeaturesThis version of DD OS offers a wide range of important software enhancements.

SMB (Server Message Block) SigningThis topic describes a new feature introduced in version 5.4.1.0 of DD OS.SMB (Server Message Block) signing is a security mechanism that improves the securityof the SMB protocol. When enabled, it is possible for clients that support SMB signing toconnect, although it is also possible for clients that do not support SMB signing toconnect. When SMB signing is required, both computers in the SMB connection mustsupport SMB signing, and the SMB connection will not be successful if one computerdoes not support SMB signing.

Note

This version of DD OS implements the SMB1 protocol.

NOTICE

SMB signing is disabled by default for performance reasons. When enabled, this featurecan cause throughput performance drops of up to 29 percent for reads and up to 50percent for writes. Individual system performance will vary.On the DD OS version where it is supported, you can configure SMB signing using theserver signing CIFS option. There are three possible values for server signing: disabled,auto, and mandatory:u When server signing is set to disabled, SMB signing is disabled. This is the default.u When server signing is set to auto, SMB signing is offered but not enforced.u When server signing is set to mandatory, SMB signing is required. Both computers in

the SMB connection must have SMB signing enabled.You can use these CLI commands to configure SMB signing:


Software Features 7

cifs option set "server signing" autoPurpose: Sets server signing to automatic.cifs option set "server signing" mandatoryPurpose: Sets server signing to mandatory.cifs option reset "server signing"Purpose: Resets server signing to the default (disabled).As a best practice, whenever you want to change the SMB signing options, first disableand then enable (restart) the CIFS service using the following CLI commands:cifs disablecifs enableYou can also use the System Manager interface to display whether the SMB serversigning option is disabled or set to auto or mandatory. To view this setting in theinterface, navigate to: Data Management > CIFS > Configuration tab. In the Options area,find the value for the server signing option.Figure 1 SMB Signing in the System Manager

Replication Enhancementsu Supports MTree replication and data migration to the retention tier on the same NFS,

CIFS, VTL or NDMP MTree to enable DR protection for long-term retention data.l Data migration policies from active tier to retention tier are configured

independently on the source and destination systems.

RELEASE NOTES


l Supports one-way and bi-directional replication topologies between Data Domainsystems with DD Extended Retention software option.

l If the source system has DD Extended Retention enabled, then the destinationmust also have DD Extended Retention software option enabled.

u Supports MTree replication for archive data locked with DD Retention LockCompliance, enabling flexible disaster recovery configurations for Data Domainsystems with backup and compliance archive data.

u Supports replication of the retention period for user-created snapshots via MTreereplication to ensure that snapshots are retained for the same period on both sourceand destination MTrees.l User-created snapshots replicated in DD OS 5.4 will retain the source snapshot

retention period. Snapshots replicated in prior releases will retain the 1-yearretention period.

u Supports collection, directory and MTree replication over IPv6 networks, allowingcustomers to take advantage of the vast IPv6 address space.l Supports simultaneous replication over IPv6 and IPv4 networks.

u Configurable replication lag alert threshold for each Data Domain system.l Default setting is 24 hours.

Inter-Release Replicationu With Data Domain Operating System (DD OS) 5.4, the following inter-release

combinations are supported for Directory and MTree replication:l DD OS 5.1 to DD OS 5.4 and vice versa (not possible when using IPv6).l DD OS 5.2 to DD OS 5.4 and vice versa (not possible when using IPv6).l DD OS 5.3 to DD OS 5.4 and vice versa (possible with IPv6).l DD OS 5.4 to DD OS 5.4 (possible with IPv6).

u Collection replication requires both the source and destination Data Domain systemsto be running DD OS 5.4

Enhancements for Archiving Use Cases on Data Domain Systemsu Fast file creation rates for small (~100 KB) files over CIFS with a new case-insensitive

file name lookup and a new Directory Name Lookup Cache (DNLC) system cache.l Archive file ingest rates of up to ~30 files/sec per single MTree per single CIFS

connection.l Archive storage data migration rates of up to 1TB/day to a Data Domain system.l Allows for support of Symantec Enterprise Vault (EV) savesets and seamless

integration for direct archive on Data Domain systems.l Faster archive rates for EV use cases, such as mailbox archive, journal archive,

and PST migrations.u Various file system improvements for enhanced consolidation of backup and archive

data on a Data Domain system.l MTree replication support for DD Retention Lock Compliance-enabled MTrees.l Heuristics-based stream management for archive data to facilitate optimal

utilization of streams in presence of backup workload.


Software Features 9

l Improved the cleaning (GC) process such that all archive data stored in addition tothe backup data on the same Data Domain system will result in a minimalincrease in the overall time taken by the cleaning operation.

u CIFS improvements:l Support for maintaining file creation time.l Better characterization and offline analysis through improved and enhanced CIFS

operations listing in ASUPs (autosupport reports).u New archive applications and partners have been qualified and certified with this

release. Refer to the Data Domain Archive Product Compatibility Guide for the completelist of archive partner/application added with this release.

Data Domain ArchiveStore Replaces Data Domain Nearline Licenseu New software license called Data Domain ArchiveStore replaces the existing Data

Domain Nearline license for tracking traditional archive-related use cases (such asfile archive, email archive, content/ECM archive, or database archive) on all DataDomain systems.l Selectable license option in DxP/CxP (no-cost license).l Data Domain ArchiveStore license can be deployed on all the current shipping and

new Data Domain systems irrespective of any other Data Domain softwarelicenses.

l The new Data Domain ArchiveStore licenses replace existing Data DomainNearline (NL) and Data Domain Backup-Nearline (BNL) licenses. After upgrading toDD OS 5.4, any NEARLINE (NL or BNL) licenses will be displayed as ARCHIVESTORElicenses.

Data Domain Extended Retention Software Enhancementsu Supports space reclamation on retention tier.

l Enables space to be reused or reclaimed after the deletion of old backup data.l Space reclamation is a continuously running background process that can be

suspended, resumed, or stopped via the CLI or from within the Data DomainSystem Manager GUI.

l Space reclamation automatically suspends itself while higher-priority processeslike Data Movement to Retention Tier or filesys clean are running, and itresumes after the higher-priority processes complete.

u Supports NDMP-based backups via NDMP protocol to Data Domain systems with DataDomain Extended Retention software option.

u Supports expanded MTree Replication functionality to enable DR protection of long-term retention data in retention tier ingested via NFS, CIFS, VTL and/or NDMP.l Mtree replication is now supported for MTrees with extended retention migration

policies.

File System Enhancementsu Increased number of concurrently accessible MTrees; supports up to 32 concurrently

accessible (active) MTrees on selected high end platforms as indicated in this table:

l Deprecation of alert messages that are no longer generated.u System configuration and support enhancements:

l Expanded network performance statistics to display all configured ethernet ports.l Enhanced capabilities of support bundle to transport over HTTPS, with

modified syntax; see support on page 19 for more information.u SNMP enhancements:

l Traps are consistently generated for all alerts, with relevant details included intrap text.

l Support for additional MIB objects including systemUser, systemLicense,ddboostOptions, snmpTrapHosts and filesysStatusMessage to support extensiblemanagement and application integration.

Enterprise Security Enhancementsu Enables the use of external signed certificates.

l Provides the ability to securely import or delete an externally created and signedhost certificate.

l Provides the ability to import or delete a host public key after the Data Domaingenerated Certificate Signing Request is signed by an external certificate authority(CA).

l Provides the ability to securely import or delete an externally created certificateauthority (CA) certificate.

l Upgrades the hash function used in the algorithm for authentication of thecertificate from MD5 to the more secure SHA1.

l Enables the use of Secure FTP (FTPS) or Secure Copy Protocol (SCP) fordownloading system log files and core files to a local PC, uploading releaseupdate RPM files, and uploading certificates.

Note

This feature is for downloading system information (logs, autosupports, supportbundles) and uploading system upgrade files. These protocols cannot be used toaccess backup data.

Oracle Optimized Deduplicationu Introduces new functionality for Oracle 11g that allows the database administrator to

use RMAN multiplexing. When enabled, the following are in place:l Improves deduplication efficiency in Oracle 11g deployments if using Oracle

multiplexing.l The deduplication ratio returns to similar levels experienced without multiplexing.

Actual deduplication improvement will depend on the block size used. Thebiggest improvement is achieved using the Oracle 8K or 16K block sizes;deduplication ratio improvements will be smaller with larger block sizes.

Note

The Oracle 4K or 32K block sizes are not supported for RMAN multiplexing.

RELEASE NOTES


u These benefits apply to the following backup scenarios:l Oracle RMAN backups of Oracle databases directly to a Data Domain system using

either CIFS or NFS protocols are supported.l DD Boost for Oracle RMAN 1.2.l Data Domain is dedicated to the Oracle workload only.

u Implementation guidelines:l Multiplexing must be disabled for any Oracle client or backup application that is

not supported; set FILESPERSET=1 and MAXOPENFILES=1.l The first full backup created after you enable this feature can significantly

increase the amount of storage used inside the Data Domain system; ensure thatsufficient space is available.

l As a general rule, ensure that the maximum storage used by old data is no morethan 30% of total space available. This should accommodate the first full backupafter enabling advanced Oracle deduplication. Be sure that the system is sizedappropriately for the desired ingest rate and retention periods.

l Deduplication rates will return to optimal levels after the first full backup and withevery subsequent backup after application-optimized compression for Oracle isenabled.

Note

These enhancements are more apparent with Oracle RMAN than with other backupapplications. Also, the throughput improvements become more apparent over time, notnecessarily immediately after upgrading.

DD Boost Enhancementsu DD Boost over Fibre Channel (FC)

l Supports DD Boost over Fibre Channel (FC) enabling disk-based simplicity in FCenvironments. FC is used as a transport, and once transport is established, everything else is

transparent to the application including features and constructs of DD Boost. DD Boost features supported over FC include aggregation, failover without

dependency on client multi-pathing software, distributed segment processing,and managed file replication over Ethernet.

l Clients: For supported clients, see the EMC DD Boost Compatibility Guide at theEMC Data Domain support portal.

l Host HBAs: Emulex LPe 11002/4GB, Emulex LPe 1205/8GB,QLogic 2562/8GB,QLogic 2462/4GB.

l Fibre Channel Switches: Brocade 6505, Brocade 6510, Brocade 300, Brocade5100, Brocade 5300 and Cisco 9100 Series Multi Layer Fabric switches.

l DD Boost over FC provides simplified management over access groups.l DD Boost over FC allows co-existence with VTL infrastructure. See deployment

guides for new installations and transitions from VTL deployments.u Supports enhanced Symantec NetBackup optimized synthetics (virtual synthetics).

l Full backup after 8-10 cycles of virtual fulls are no longer needed for Data Domainsystems with memory larger than 4GB, which include these models:DD140, DD160, DD565, DD580, DD610, DD620, DD630, DD640, DD660, DD690,DD670, DD860, DD880, DD890, and DD990.



l No change to requirement for full backup after 8-10 cycles of virtual fulls forsystems with smaller than 4GB memory which include these models:DD120, DD510, and DD530.

u Supports backing up an application/media server to a remotely located Data Domainsystem under the following application and network characteristics:l Applications: EMC NetWorker and Symantec NetBackup.l Network characteristics:

Network Speed: 100 Mb to 10 Gb Ethernet (full duplex). Round Trip Time (RTT): Up to 5 ms. Bandwidth: Unrestricted bandwidth for the above network speed. Packet Loss: < 0.001% including packet fragmentation.

u Supports Symantec NetBackup Auto Image Replication (AIR), which provides theability to automatically manage the replication of a deduplicated backup image fromone NetBackup master server domain to another.l Support for AIR results in faster time to DR for critical backup images, automatic

cataloging and significantly improved RTO between two different NetBackupdomains. It will also simplify connectivity as there is no more need for local mediaserver to connect to both sides; the communication with second site happensremotely.

l Supports a point-to-point replication configuration.u Supports Symantec NetBackup 7.5.0.4 Accelerator for file system workloads with low

change rates.l Supports virtual synthetic full backups on the Data Domain system.

Note

In versions of NetBackup prior to 7.5.0.4, jobs may fail with a message such as thefollowing:11/07/2012 11:58:35 - Critical bptm (pid=9739)A portion of data to be included from a previous backup(backupid = ostqa-linux2_1351870224, offset = 661288960,length = 36352) has incorrect checksum (calculated checksumfrom backup image faf2aff1392269d36db7dbcc211f3d97b3f526ed,expected checksum 2345ea1603b4cb4ae2c29e5f6a9353e7832faee6)

The workaround for this problem is to upgrade to NetBackup 7.5.0.4 or later.u Data Domain virtual synthetic backups are supported with EMC NetWorker 8.1 and

EMC Avamar 7.0.u All the new features of DD Boost over FC and most of the features of NBU AIR can be

managed using the DD System Manager GUI.u For supported configurations, see the EMC DD Boost Compatibility Guide at the EMC

Data Domain support portal.

Networking EnhancementsThis version of DD OS includes the following enhanced networking features.IPv6 Support for Replicationu IPv6 support is added for directory replication, collection replication and MTree

replication. This allows users to take advantage of the vast address space availablewith IPv6. Managed file replication over IPv6 networks is not supported in thisrelease.

RELEASE NOTES


u IPv6 is not supported for backup protocols in this release.u IPv6 support can be configured using the CLI. Configuring IPv6 addresses in the DD

System Manager (formerly Enterprise Manager) GUI is not currently supported.u Both the source and destination system must be configured with IPv6.u A single Data Domain system can be configured with both IPv4 and IPv6, thereby

allowing some replication traffic to flow over IPv4 networks (if one of the sites doesnot have IPv6 capabilities) and other replication traffic to flow over IPv6 networks.

New Operations to Enhance Network Supportabilityu An alert indicating the presence of an invalid network card is added in this release. If

an invalid network card is detected, an alert is sent; however, ongoing operations arenot suspended. This check is always enabled and cannot be disabled. Because theuse of an unsupported network card can result in unexpected errors, the alertprovides a recommendation to remove the invalid card.

u The net show stats detailed command provides more complete informationthan in previous releases.

u The congestion monitor is now enabled by default. To adjust and configure thecongestion monitor, use the net congestion-check command.

VTL Enhancementsu Expanded tape library emulations for open systems to support ADIC i2000 tape

library emulation.u Expanded tape drive emulations for open systems environments to support the

following:l HP LTO-3 tape drive emulation.l HP LTO-4 tape drive emulation.l IBM LTO-4 tape drive emulation.

u Expanded tape drive emulation for IBM i environments using IBM LTO-4 tape drivesupport emulation.

u Ability to perform a complete IBM i installation from Data Domain VTL, eliminating theneed for the IBM Software Distribution Media DVD (also known as IBM i systemrecovery IPL Type D from tape).

u Ability to assign VTL LUN 0 from multiple target ports for greater deploymentflexibility.

u Improved scalability by supporting 1024 initiators and 2048 access groups.u Enhanced capability to track tape location history.

Data Domain Encryption Enhancementsu Supports local encryption key management for DD Encryption of data at rest.

l Enables local key management with key rotation with the same key types andstates; up to 254 keys allowed.

l Configured and managed through either the CLI or the DD System Manager GUI.l Supports a secure key import and export function via CLI using either SCP or SFTP

to enable customers to store their keys safely in an external location.l Included with DD Encryption license.



u Supports the co-existence of multiple key management options for DD Encryption onthe same DD system enabling the customer flexible migration to and from the othertypes of encryption key management.l Supports default local key management, basic static encryption key, and RSA

DPM external key manager.l If local key management is used and the user upgrades to a RSA DPM

environment at a later time, the local keys will not be visible to RSA DPM andthose keys created prior to the upgrade to DPM will have to be managed locally onthe Data Domain system.

The scsitarget command is not supported on GlobalDeduplication Arrays (GDAs).The SCSI target subsystem configuration comprises several SCSI target entities:u services (VTL and DD Boost)u transports (Fibre Channel)u endpoints (virtual ports that map to system addresses that are Fibre Channel

interfaces)u logical devicesu host initiatorsu access groupsThese are the options used with the scsitarget command:u deviceu disableu enableu endpointu groupu initiatoru persistent-reservationu resetu service

Fixed IssuesThis release of DD OS, 5.4.3.0-436446, includes a number of fixed issues. The releasealso includes fixed issues from prior releases in the DD OS 5.4 feature family.

Fixed in Version 5.4.3.0-436446This topic lists important changes and fixes made to this version of DD OS.Table 8 DD OS 5.4.3.0DD Boost Issues: Fixed

Bug # Description107995 Fixed an issue where a packet that was malformed in transit caused a file system

panic during decompression.108386 Fixed the issue in which Backup Exec 2012 duplicate jobs could fail for backups

that were sent directly from Backup Exec 2012 to the Data Domain system.110464 Fixed the issue in which an inventory of the Data Domain device by Backup Exec

could fail due to an incorrect error code.111191 Fixed the issue in which the number of ifgroup clients could not be increased above

a maximum of 256.115522 Fixed the issue in which some zero-length files that were used as event semaphores

were deleted prematurely, which could cause some files to be omitted from abackup catalog.


Fixed Issues 31

Table 9 DD OS 5.4.3.0File System Issues: Fixed

Bug # Description78040 Fixed the issue in which a Data Domain system reported incorrect MTree and

compression statistics due to double accounting for raw bytes on references andsegments.

92919 Fixed the issue in which consecutive markers were merged in an incoming datastream, and when the merged markers exceeded a certain byte length, then a zero-size segment reference resulted, causing the file system to crash. This issue onlyoccurred when Oracle application optimization is enabled.

94286 Fixed the issue in which Data Domain system performance could degrade becausesome opaque entries created for snapshots on systems with MTree replication werenot deleted as expected on the replica, and the accumulation these stale opaqueentries affected system performance.

104408 Fixed the issue in which opening a spanning file could result in a file system panicdue to a health monitor timeout on a Data Domain system with the ExtendedRetention software option enabled.

104919 Fixed the issue in which users could not authenticate with CIFS following anupgrade to DD OS 5.4.0.7.

106315 Fixed the issue in which backups could fail due to resource contention with spacereclamation processes.

107665 Fixed the issue in which a DD2500 system was not correctly tuned, which causedresulted in memory issues and a file system panic.

108380 Fixed the issue in which a Data Domain system, after recently running garbagecollection, experienced timeouts for several NFS or DD Boost remote procedurecalls at an increasing rate. The RPC timeouts followed a situation in which the fileverification process verified files in the ASUP without capturing the correcttimestamp. The problem usually disappeared after a system panic and restart.

108749 Fixed the issue in which users belonging to an Active Directory Domain whoseNETBIOS name is not unique in the Active Directory forest could not authenticate.

109657 Fixed the issue in which a CIFS group name or a CIFS group member's usernamecontaining the $ character followed by two non-hex characters could causeoperations involving either of those names, including logins, to fail.

110535 Fixed the issue in which a Data Domain system with the Extended Retentionsoftware option enabled could panic during archive data movement if the writestream count for ingest exceeded the maximum supported by the system.

113664 Fixed the issue in which a Data Domain system could panic with NetBackup AIRbecause of anomalies introduced on the wire into requests to close a file.

Bug # Description108678 Fixed the issue in which a Data Domain system running DD OS version 5.2.2.4 could

become unresponsive to RPC services queries, requiring a hard reboot to restorefunctionality.


Bug # Description105326 Fixed the issue in which a Data Domain system could panic due to an RPC timeout

that occurred due to an excess of files awaiting processing.106249 Fixed the issue in which NetBackup Automatic Image Replication jobs failed due to

an image metadata (_IM) file error when the fragment file(s) (_F1, _F2, ...) tooklonger than 10 minutes to complete. The Knowledge Base article 95090 containsfurther details.

107015 Fixed the issue in which DDBoost over Fibre Channel failed to start when invalidendpoints were present on the Data Domain system.

Table 21 DD OS 5.4.2.0File System Issues: Fixed

Bug # Description81531 Fixed the issue in which a Data Domain system with NFS_LOG_IMMEDIATE_SIZE

set to 64k and using small writes was not able to recover from any previous DataDomain file system panic, with the added result that backup jobs affected by thepanic needed to be re-done.

86411 Fixed the issue in which the Data Domain file system was using only 1GB ofcontiguous memory heap, which leads to memory fragmentation inside the filesystem in the long term because the libc allocator did not scale optimally withnon-contagious memory. This fix reduces memory fragmentation in the file system'svirtual memory space and helps the file system run longer.

98162 Fixed the issue in which a race condition between garbage collection enumerationand segment processing could lead to a Data Domain file system panic.

100254 Fixed the issue in which the Data Domain file system could panic when overwritingbackup files with densely populated markers.

102307 Fixed the issue in which a DD Boost virtual synthetics backup by means of anAvamar high-generation backup or a NetBackup Accelerator rescan backup couldfail during the ingest phase with error 5048 (indicating a limit on t0 segmentreferences in a t1 segment) or sometimes, incorrectly, with error 5044 (indicatingthat the file system is read-only).

102547 Fixed the issue in which the Data Domain file system crashed due to a problemencountered with MTree replication of backups optimized by the virtual syntheticsfeature between Data Domain systems with different DD OS families.



Table 21 DD OS 5.4.2.0File System Issues: Fixed (continued)

Bug # Description102830 Fixed the issue in which the filesys destroy and-zero operation produced

operation timeout errors and provided no progress indicators when executed on aData Domain system with the Extended Retention software option enabled.

102988 Fixed the issue in which the number of managed file replication jobs could exceedthe maximum allowed filecopy streams. Because of this error condition, data-movement processes could fail to start and could handle the error improperly. Theimproper error handling could cause a memory leak that in turn caused a filesystem panic during a file system shutdown.

104641 Fixed the issue in which the filesys verify resume command may not insome cases resume its scrubbing function.

104672 Fixed the issue in which the file system of a Data Domain system that had beenupgraded to DD OS version 5.4.0.7 could panic continuously.

104676 Fixed the issue in which certain types of write workloads could exhibit degradedperformance.

104821 Fixed the issue in which the Data Domain file system could panic due to a racecondition between two threads that negatively affected a backup job.

105111 Fixed the issue in which a mismatch in the number of segments read during deltareplication from a source Data Domain system running DD OS version 5.3 or newerto a destination Data Domain system running a version of DD OS older than 5.3destabilized the file system on the source system and caused repeated file systempanics.

105121 Fixed the issue in which users could unintentionally create anomalies by enablingExtended Retention on a Data Domain system using the System Manager GUI evenif encryption had previously been used on the system. The Extended Retentionsoftware option cannot be enabled on a Data Domain system if the system hasused encryption previously; all encrypted data needs to be cleared of encryption,and all encryption settings need to be removed before the Extended Retentionsoftware option can be enabled.

105503 Fixed the issue in which the Data Domain file system dumped core because of anerror in the system registry.

107213 Fixed the issue in which a Data Domain system user with user or backup-operator roles was unable to run the replication sync command.

108927 Fixed the issue in which the DD OS file system could panic when using MTreereplication from a Data Domain source system running DD OS 5.4.1.x or 5.4.0.x to adestination system running DD OS 5.1.x where no MTree quota was set on thesource system.


Bug # Description103731 Fixed the issue in which the Replication Summary Report in the System Manager

GUI displayed a misleading label for the Y-axis in the summary chart of the report.The Y-axis is now correctly labeled as Network Bytes (MiB) instead of NetworkIn&Out (Mbps).

Bug # Description105933 Fixed the issue in which users could not add a Data Domain system in the

Enterprise Manager if the registry keys were missing or in some other anomalousstate.


Bug # Description93458 Fixed the issue in which the DD OS filesystem could panic because the Data

Domain system failed to attach a shared memory segment. This could occur for avariety of reasons. As a result of this fix, an error message is logged, and there is nofilesystem panic.

95983 Fixed the issue in which Data Domain file system could panic if a colon character (:)is present in any field of an NFS rmtab entry.

100269 Fixed the issue in which the output of the ddboost file-replication showstats command and the contents of the ddboostFileReplicationStatsTable object(.1.3.6.1.4.1.19746.1.12.5.1 ) were not consistent.

100352 Fixed the issue in which an unresolved symbolic link led to an asynchronous RPCtimeout, which in turn caused a Data Domain file system panic.

102419 Fixed the issue in which DD Boost looked up and opened streams that NFS had justclosed, which in turn caused NFS to close the streams again. This could happenrepeatedly and could cause performance stalls.

105014 Fixed the issue in which an NFS remote procedure call could become delayed andultimately cause a file system panic. The delay could occur if a large number ofstreams needs to be flushed at the same time the RPC is being processed.

105408 Fixed the issue in which the Data Domain file system panicked when anautosupport job ran the filesys show detailed-stats command.

105620 Fixed the issue in which a soft lock could cause a system panic after upgrading aData Domain system to DD OS 5.4.0.8.


Bug # Description77396 Fixed the issue in which a Data Domain system controller upgrade could not be

performed on a system where the expansion shelf was at a level of DD OSpreceding than the head. For example, if the head was at DD OS 5.4 but theexpansion shelf was at DD OS 5.2, the controller could not be upgraded. In thecurrent feature family (DD OS 5.5), the upgrade can proceed.

88664 Implemented a process to reduce IO latency and to avoid file system slowdowns byplacing an upper limit on the number of retries executed for IO that completed withan error.

95405 Fixed the issue in which Data Domain systems became unusable if the log directory(/ddr/var/log/debug/cifs) was accidentally deleted. The log directory isautomatically recreated on the next system boot.

Bug # Description96692 Fixed the issue which caused a segmentation fault in SMS and a general protection

fault in SNMP.98970 Fixed the issue in which a DIMM error message did not include the correct DIMM

location.100849 Fixed the issue in which some DD640, DD670, DD860, and DD890 platforms report

spurious environmental alerts (such as voltage threshold, chassis temperaturethreshold, or fan speed) in the storage controller chassis. This platform firmwareissue was first addressed with a DD OS change in releases 5.1.4.0, 5.2.3.0, 5.3.1.0and later major releases. However, that previous change did not completelyaddress the problem.

103139 Fixed the issue in which the process that generates autosupport reports could enteran infinite loop, which could overtake most of the CPU resources, necessitating asystem reboot to restore normal operations. This issue occurred only with PCIehardware problems.

103153 Fixed the issue in which historical database pruning failed because of insufficientspace on the participation in which to perform some of the pruning operations.

104609 Fixed the issue in which garbage collection enumeration, an initial phase of systemcleaning, could become suspended, causing significant performance degradation.This issue only affected Data Domain systems that used virtual synthetics.

104869 Fixed the issue in which a Data Domain system unexpectedly rebooted after diskreconstruction.

105341 Fixed the issue in which a DD120, DD510, or DD530 model system could issue aspurious core dump capability alert when the system's core dump capability wasnot impaired.

107119 Fixed the issue in which the System Management Service could run out of memory,possibly causing a system crash, followed by a system restart.


Bug # Description97005 Fixed the issue in which system cleaning (garbage collection) could incur a

significant performance reduction if a replication context is broken during thecleaning process. The fix resolves an situation that the broken replication contextleft open, causing the system cleaning slowdown.

100752 Fixed the issue in which a delayed file deletion in a replication pair led to anasynchronous RPC timeout, which in turn caused a Data Domain file system panic.

102465 Fixed the issue in which space reclamation could stall on a Data Domain systemwith collection replication configured if the system crashed during garbagecollection.

103650 Fixed the issue in which a Data Domain system could become unresponsivebecause too many active replication contexts overloaded System ManagementServices with status requests that by default required locks.

incident, and snapshots that should have been deleted could remain, even thoughthe Data Domain system considered the snapshots to be expired.

104071 Fixed the issue in which the Data Domain file system could panic when aNetBackup Auto-Image Replication (AIR) operation tried to create a file on an MTreereplication destination.

105045 Fixed the issue in which directory replication failed between two Data Domainsystems because of a mismatch between encryption settings on the two systems.

106815 Fixed the issue in which a Data Domain system using managed file replication withreplication throttling could hang, panic, or exhibit slowed performance.

107664 Fixed the issue affecting MTree Replication where the source Data Domain systemhas the Extended Retention software option enabled. A panic could occur on thedestination Data Domain system because the format of a file on the source systemhas undergone a change due to the file's migration to the Retention tier.


Bug # Description103414 Fixed the issue in which is was not possible to delete a VTL pool from the Enterprise

Manager GUI, while it was possible from the DD OS command line interface.105109 Fixed the issue in which users could not use the DD System Manager (GUI) to select

and configure an endpoint for Fibre Channel access group devices if the endpointhad previously been renamed.

105927 Fixed the issue in which a VTL upgrade (as part of a DD OS upgrade) failed becausenon-existent Fibre Channel ports existed in the VTL configuration. A port couldbecome non-existent if its configuration changed, such as by replacing a FibreChannel interface with an Ethernet interface. The upgrade process now checks fornon-existent VTL ports and disallows the upgrade if non-existent ports are detected.

Bug # Description93670 Fixed the issue in which the ddboost status, ddboost show user-name

and ddboost show connections commands could fail with an errorcontaining the RPC error=12 message if the number of DD Boost clientsexceeded 100. This error did not adversely impact any backup, restore, orreplication operations.

95869 Fixed the issue that affected adding and managing DD Boost clients. As a result ofthis fix, all clients will report fully qualified domain names (FQDN) when reportingthe host name to the Data Domain system. Customers who configured individualclient names for ddboost access or ddboost ifgroup will need to modifytheir configuration to include the FQDN of the clients. However, this enhancementallows easier configuration if *.domainname satisfies the needed configuration.Be aware that clients are expected to be configured for domain name support,based on client platform type. Windows clients are expected to be configured with adomain name in the registry. To perform this configuration, click Start > Run, openregedit, and look for this entry:HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Domain

99178 Fixed the issue in which a Data Domain source system could panic if a NetBackupAuto Image Replication (AIR) job was cancelled.
