volume groups are created on the Primary server for the SAP system and the database, respectively.

DB2 Universal Database v7.2 for AIX® is used; DB2 UDB suspended I/O capabilities are available on all platforms supported by DB2 UDB.

An IBM ESS 2105 F20 is used. The same scenarios also pertain to other ESS models supporting the same functionality as the ESS F20, such as the ESS Model 800 (Silvertip). The servers were attached to the ESS via SCSI adapters, but alternatively fibre channel may be used.

Installing Advanced Copy Services

An IBM representative should install Copy Services on the ESS 2105 F20. Copy Services is a separately sold feature of the ESS. It includes FlashCopy for the Open Systems environment.

Installing the Command Line Interface on AIX

Install the ESS Command Line Interface on the AIX server from which you want to execute the FlashCopy tasks. Alternatively, you can also execute the FlashCopy tasks from the ESS Copy Services Web Interface.

Install the Copy Services Command Line Interface software. It requires the IBM 2105 Runtime environment for AIX as a prerequisite.

The installation fileset of the Command Line Interface is named ibm2105cli.rte. The destination of the fileset is /usr/opt/ibm2105cli. The installation fileset of the IBM 2105 Runtime environment for AIX is ibm2105.rte. The destination of the fileset is /usr/opt/ibm2105.

Creating and assigning ESS logical volumes

1.Use the StorWatch ESS Specialist Web Interface to define logical volumes and assign them to the Primary and the Backup server.

a.Select Storage Allocation from the StorWatch ESS Specialist menu

b.Select Open Systems Storage -> Modify Volume Assignments -> Add

Volumes

c.Select the server, the SCSI adapter to which the logical volume(s) should be attached, and the disk group on which the logical volumes should be created and click Next.

d.Select Raid-5as storage type, specify the size and number of logical volumes and click Perform Configuration Update.

e.Repeat these steps until you have created and assigned all logical volumes that are required.

Make sure that for each source disk you create a target disk of the same size or bigger in the same ESS LSS.

2.On each AIX server, run cfgmgr to define SCSI paths to the ESS. The ESS logical volumes will be visible as hdisks on the Primary and Backup servers. Use the following AIX command to list the ESS logical volumes assigned to a server:
