the procedure below, bring the

OBVS_VELOCIS

and

OBVS_MCRS

cluster groups online using the Cluster Administrator utility.

How to Replay
Transaction Logs

Proceed as follows:

1. Run the following command to replay the transaction logs:

omnidbrestore -replay_only -firstlog

where

is the first transaction log that was

created just after the IDB backup was started.

At the end of the

omnidbrestore -autorecover

output, Data

Protector displays the exact command you should use to replay the
transaction logs, giving you the name of the first transaction log.

For example, the command could be:

omnidbrestore -replay_only -firstlog AAAAAC

where

AAAAAC

is the first transaction log created after the IDB

backup was started.

2. Run the

omnidbcheck

command.

This completes the recovery procedure.

Recovering the IDB to a Different Disk Layout

You can restore the IDB to a disk of a different size than before the
disaster, and to different directories than at the backup time.

Prerequisites

Ensure the following before recovering the IDB to a different disk layout:

• If possible, store the

media.log

file from the previous installation to

a safe place. It will provide you with information about the media
used since the last IDB backup.

• Verify that Data Protector is installed on the Cell Manager and the

system where a device is attached. (Preferably, this device was used
for the IDB backup.)

• Import the media with the IDB backup.
