DS3300 iSCSI Components

• Core I/O protocol support for iSCSI:• Protocol-specific error handling and recovery for iSCSI.• iSCSI name/address management.

• Ancillary protocol support for protocols that are required for a workable iSCSI solution:

• SNMP• DHCP• iSNS

• Controller Properties management • iSCSI Ethernet port names and IP addresses• Packet size attributes• Authentication method selection• Management of “shared secrets” (i.e. passwords)


System StorageTM


Powering the DS3300

• Power on and off order are important• Power on

• Turn on the power switch on both power-fan canisters on any attached EXP3000 drive trays

• Turn on the power switch on both power-fan canisters on the DS3300 • Check that all lights show normal operation

• Reverse the order for power down. (make sure IO is stopped prior to power down)

Mis-wire Reporting

• When a Mis-wire condition is detected the RAID controller firmware will report the following:

• A “Needs Attention” condition • A critical MEL event indicating the presence of the Mis-wire Condition• A Recovery Action (Recovery Guru) indicating the Mis-wire


System StorageTM


“Needs-Attention” Condition

• The presence of a SAS Mis-wire condition is graphically reported to the user in the form of a “Needs Attention” condition

• When the Mis-wire condition is corrected, the “Needs Attention” condition will be removed.

Storage Manager GUI Changes

New iSCSI tab


System StorageTM


Storage Manager iSCSI Tab

Storage Manager iSCSI tab provides these components:

• Change Target Authentication

• Enter Mutual Authentication Permissions

• Change Target Identification

• Change Target Discovery• Configure iSCSI Host

Ports• View/End iSCSI Sessions• View iSCSI Statistics


System StorageTM


Change Target Authentication

• None (default)• CHAP

• 12 to 57 characters• May be randomly generated

• Initiator must know secret in order to use the array


System StorageTM


Mutual Authentication Permissions

• Two-way authentication

• Enables a client to validate itself to a server and for the server to validate itself to the client

• By default, the initiator authenticates to the target (CHAP)

• With mutual authentication the target authenticates to the initiator


System StorageTM


Identification and Networking

• Note the iSCSI name format• Not all initiators support aliases (Microsoft software initiator

currently does not)


System StorageTM


Identification and Networking

• If iSNS discovery is enabled for the subsystem but the iSNS server IP address and port number are not located using DHCP, the controller firmware uses the user-supplied iSNS server IP address and port number to configure the iSNS server location.


System StorageTM


Configure iSCSI Host Ports

• Static or DHCP• Currently IPv4

• Enable ICMP PING responses


System StorageTM


Configure iSCSI Host Ports


System StorageTM


DS3300 iSCSI Partitions

• Storage Partitions adjustments for iSCSI:• Provide Storage Manager support for iSCSI topology definition • Accommodations for Host Port entities and iSCSI Initiator entities• The Host Context Agent understands how to collect iSCSI information

about host systems and push this information to the controller


System StorageTM


Storage Manager Components

Storage Manager software is comprised of these software components:

• Storage Manager java application (SMclient)

• Storage Manager in-band management agent (SMagent)

• Storage Manager Utilities

• Failover Driver (MPIO or RDAC, depending on OS)


System StorageTM


Storage Manager Java Application (SMclient)

• Storage Manager Java Application is used to monitor and manage the DS3300 storage system over LANs, WANs

• Can be installed on a management station or a host

• Uses SMagent (In-Band) and the DS3300 API (Out-of-Band)

Out of Band

IP address of controller

System StorageTM


Setting the initial out of band IP address

• Default method is to use DHCP• If there is no DHCP server the default IP address for the controllers

are:• Controller 0: 192.168.128.101• Controller 1: 192.168.128.102• Port 2463 (registered with IANA;

http://www.iana.org/assignments/port-numbers)• Storage Manager uses TCP for connections• Storage Manager uses UDP broadcast on local subnet for automatic discovery

• Three methods to change the default values• By using a client with Storage Manager connected out-of-band with a cross-

over cable between the host and the controllers’ management ports• By using a client with Storage Manager connected in-band with a cross-over

cable between the host and the controllers’ host ports

Initial in-band IP address

• The default host port IP address for the controllers are:• Controller 0 iSCSI Port 0: 192.168.130.101• Controller 0 iSCSI Port 1: 192.168.131.101• Controller 1 iSCSI Port 0: 192.168.130.102• Controller 1 iSCSI Port 1: 192.168.131.102

• Three methods to change the initial default values• By using a client with Storage Manager connected out-of-band with a

cross-over cable between the host and the controllers’ management ports

• By using a client with Storage Manager connected in-band with a cross-over cable between the host and the controllers’ host ports

Storage Manager Configuration Files

• Storage Manager uses a primary and backup configuration file • emwdata_v0X.bin• emwback_v0X.bin

• A list of storage arrays and hosts included in the management domain

• The name of the mail server you have set to forward e-mail to configured e-mail alert destinations.

• The sender's e-mail address you have set that will appear on every mail message sent to configured e-mail alert destinations.

• Alert notification destination addresses you have set for e-mail and SNMP trap messages about individual storage systems in the management domain.
