9.1.2 Planning for storage and database protection

In this section we will give some considerations how to plan the storage and

Tivoli Storage Manager database protection. For more details, please refer to:

“Protecting and Recovering Your Server” in the Administrators Guide.

For this configuration example we chose to have:

Tivoli Storage Manager server:

򐂰 Code installed under rootvg filesystems /usr on both nodes

򐂰 Tivoli Storage Manager mirroring for database and log volumes

򐂰 RAID0 shared disks volumes configured on separate storage subsystem

arrays for database and log volumes copies

–/tsm/db1

– /tsm/db1mr

–/tsm/lg1

–/tsm/lg1mr

򐂰 Database and log writes set to sequential (which disables

DBPAGESHADOW)

򐂰 Log mode set to RollForward

򐂰 RAID1 shared disk volumes for configuration files and disk storage pools.

– /tsm/files

–/tsm/dp1

Tivoli Storage Manager Administration Center

Note: The Administration Center can be a critical application for environments

where administrator and operators are not confident with the

IBM Tivoli

Storage Manager Command Line Administrative Interface

. So we decided to

experiment with a clustered installation, even if it is not currently supported.
