Chapter 2Checking the Server Environment

Connection to servers is possible in the following environments.

Check the "Server Support Matrix" for server environment conditions.

2.1 Hardware

Refer to the "Server Support Matrix".

2.2 Operating System (OS)


2.3 Fibre Channel Cards


2.4 Veritas Volume Manager (VxVM)


2.5 Veritas Cluster Server (VCS)




Chapter 3Notes

Note the following issues when connecting the ETERNUS DX/AF to a server.

3.1 ETERNUS DX/AF Setup Notes

The following settings will depend on the exact connection conditions.

• Host Response settings

"Host Specific Mode" and "Reservation Conflict Response for Test Unit Ready" settings

• Reset Group settings

Perform the settings correctly by referring to "Configuration Guide -Server Connection- Storage System Set-tings" that corresponds to the ETERNUS DX/AF to be connected.

3.2 Notes Regarding the Number of LUNs

The maximum number of LUNs vary according to the system environment.

System environment

ETERNUS DX/AF

ETERNUS DX S4/S3 series,ETERNUS AF series,ETERNUS DX200F,ETERNUS DX80 S2/DX90 S2,ETERNUS DX400 S2 series,ETERNUS DX8000 S2 series

ETERNUS DX60 S2

Single path (FJspio) environment Maximum 512 LUNs Maximum 256 LUNs

ETERNUS DX/AF ODM package for AIXMPIO

Exact details depend on the OS being used.There are no specific ODM package restrictions.

ETERNUS Multipath Driver 2 (AIX) envi-ronment

Exact details depend on the OS being used.There are no specific multipath driver restrictions.



3.3 Fibre Channel Switch Notes

The Fibre Channel switches that can be connected depend on the connection configuration that is used (theOS and the ETERNUS DX/AF). Refer to the "Server Support Matrix for FC-SWITCH" before starting.

When a Fibre Channel switch (ETERNUS SN200 series, Brocade series) is to be used between the server andETERNUS DX/AF, follow the preparation-in-advance and Fibre Channel switch setup procedures given in the"Configuration Guide -Server Connection- (Fibre Channel) Fibre Channel Switch Settings".

• If AIX server is connected to a Fibre Channel switch, the Fibre Channel switch port link speed must be set.Set the link speed of the Fibre Channel switch ports according to the link speeds of the server-side FibreChannel cards, as follows:

Combination of devicesSet the Fibre Channel switch port linkspeed to...Maximum link speed of Fibre Channel

cardMaximum link speed of the FibreChannel switch

8Gbit/s 32Gbit/s 8Gbit/s fixed

16Gbit/s 8Gbit/s fixed




4Gbit/s 32Gbit/s —





2Gbit/s 32Gbit/s —

16Gbit/s —




If the devices being connected together both have automatically set link speeds, the resulting link speedmay be less than optimal. The default link speed setting for Fibre Channel switch ports is "Automatic". Thelink speed setting of a true IBM Fibre Channel card cannot be changed to other than "Automatic", so theFibre Channel switch port link speeds must be fixed to match the actual speed of the server-side FibreChannel cards, as per the above table, so that the same link speed is always used.

3.4 LVM Notes

Disable [Bad Block Relocation] for a LVM logical volume that was created on ETERNUS DX/AF storage sys-tems' LUN. Also, [Bad Block Relocation] must be disabled for the logical volume in which file system logs arestored.

Chapter 3 Notes3.3 Fibre Channel Switch Notes



3.5 Server Startup and Power Supply Control Notes

Before turning the server on, check that the ETERNUS DX/AF storage systems and Fibre Channel switches areall "Ready". If the server is turned on and they are not "Ready", the server will not be able to recognize theETERNUS DX/AF storage systems.

Also, when the ETERNUS DX/AF power supply is being controlled by a connected server, make sure that theETERNUS DX/AF does not shut down before the connected servers. Similarly, the Fibre Channel switches mustalso be turned off after the connected servers have been shut down. If turned off, data writes from the run-ning server cannot be saved to the ETERNUS DX/AF storage systems, and already saved data may also beaffected.

3.6 Veritas Volume Manager (VxVM) Notes

• Confirm and acquire the ASL required for using the ETERNUS DX/AF storage systems from the following Ver-itas web-site.

https://sort.veritas.com/asl

• Refer to "8.4 Installing the FJspio Package" (page 22) and install the FJspio package on the AIX systembefore installing VxVM.

• Install Veritas Array Support Library (ASL) after installing VxVM.

• For VxVM 5.1 or later

ASL does not need to be installed.

3.7 Notes for Veritas Volume Manager Dynamic Multipathing(VxVM DMP)

When using the VxVM DMP function, do not use it with a single path configuration.

3.8 Veritas Cluster Server (VCS) Notes

Veritas Cluster Server should be installed according to the directions given in the documentation providedwith Veritas Cluster Server.

3.9 Multipath Notes

Refer to the "Server Support Matrix" for details of the different combinations of Multipath configurations.

Chapter 3 Notes3.5 Server Startup and Power Supply Control Notes



3.10 Virtual I/O Server (VIOS) Notes

• Perform the settings described in this manual only for a VIOS.

When performing VIOS settings or installing software, the root privilege for the VIOS environment is re-quired.

• To use a VIOS, ETERNUS Multipath Driver 2 (AIX) or FJSVmpio is required. Install ETERNUS Multipath Driver 2(AIX) or FJSVmpio in the VIOS.

• Configuring LVM on the VIOS is not supported.

3.11 Oracle RAC Notes

• Set the CSS miscount parameter to a value of 60 or higher.

• Set "fc_err_recov", an "fscsi" attribute, to "fast_fail".

3.12 Path Addition Notes

Added paths may not be automatically recognized if the OS is not rebooted after adding the paths. In thatcase, execute the following command.

#cfgmgr

In addition, if Veritas Volume Manager (VxVM) is used, execute the following command.

#vxdctl enable

Chapter 3 Notes3.10 Virtual I/O Server (VIOS) Notes



Chapter 4Checking the Server Information

Check the World Wide Name (WWN).

Execute the following command to display the WWN of fcs0.

# lscfg -vl fcs0

The WWN is displayed in the [Network Address].

If multiple Fibre Channel cards are installed, change the parameter and re-execute the command.



Chapter 5Installing and Setting Up ETERNUSmgr

If ETERNUSmgr is to be used, install it according to the directions given in the "ETERNUSmgr Install Guide".After installation is complete, follow the instructions in "ETERNUSmgr User Guide" and set up ETERNUSmgr.



Chapter 6Setting Up the ETERNUS DX/AF

Set up the ETERNUS DX/AF storage systems using ETERNUS Web GUI or ETERNUSmgr.

ETERNUS DX/AF setup can be performed independently of server setup. For details on how to perform thesesettings, refer to the following manuals.

• "Configuration Guide -Server Connection- Storage System Settings" that corresponds to the ETERNUS DX/AFto be connected

• "ETERNUS Web GUI User's Guide" or "ETERNUSmgr User Guide"



Chapter 7Setting Up the Fibre Channel Switches

Perform the settings required to connect the ETERNUS DX/AF storage systems and server via the Fibre Chan-nel switch, according to "Configuration Guide -Server Connection- (Fibre Channel) Fibre Channel Switch Set-tings".

If the access path is set with ETERNUS SF Storage Cruiser, the Host Response settings are set to the defaultvalues.

• Refer to "Server Support Matrix" to check the support status of SAN Boot and refer to the manual of theserver, OS, or the Fibre Channel card that is to be used.

• When using a logical unit (LUN) of the ETERNUS DX/AF storage systems as a boot disk, make sure that theLUN has enough capacity to install the OS.



Chapter 13Storage Migration

This chapter explains how to configure the server for performing Storage Migration.

When Storage Migration is performed, configure the settings so that the ETERNUS DX/AF LUNs can be usedfrom the server (AIX).

■ Setting Procedure Outline

Execute the operation to start Storage Migration from ETERNUS Web GUI. Perform all other operations in theserver (AIX).

1 Unmount the file system.

2 Deactivate the volume group.

3 Export the volume group.

4 Remove the LUN.

5 Turn off the server.

6 Start Storage Migration, change the connection destination to the migration destination ETERNUSDX/AF, and then reboot the server.

7 Import the volume group.

8 Mount the file system.

■ Example Setting Procedure

The following procedure shows an example configuration for AIX 6.1.

1 Unmount the file system.
