Managing the Data Protector Internal Database

Recovering the IDB

procedure for recovering the IDB to a different disk/volume layout. You can use the -previewoption of the omnidbrestore command to see where the files will be restored.

•If possible, move the media.log file from the previous installation to a safe place. It will provide you with the information about the media used since the last IDB backup. This is very helpful for updating the IDB if transaction logs are not available.

•Verify that Data Protector is installed on the Cell Manager and the system where a device is attached (preferably, the device used for the IDB backup).

•If the IDB is installed on MC/ServiceGuard, run the cmhaltpkg <pkg_name> command on the active node before performing the guided autorecovery, to stop the Data Protector package. When the guided autorecovery has finished, run the cmrunpkg <pkg_name> command on the active node to start the Data Protector package, where <pkg_name> is the name of the Data Protector cluster package.

•If the IDB is installed on Microsoft Cluster Server, take the

OBVS_VELOCIS cluster group offline using the Cluster Administrator utility on the active node before performing the guided autorecovery. When the guided autorecovery has finished, bring the OBVS_VELOCIS and OBVS_MCRS cluster groups online using the Cluster Administrator utility.

Recovery	1. Check all backups using the following command:
Procedure	omnidbrestore -autorecover -logview -skiprestore
	2. Choose the backup session you want to restore from and perform the
	restore by running the omnidbrestore -autorecover -session
	<sessionID> command.
	For example, if you choose to restore from the backup session
	2000/12/26-1and the original device used for the IDB backup exists,
	run:
	omnidbrestore -autorecover -session 2000/12/26-1
	The command guides you through restoring the IDB and replaying
	transaction logs since the last IDB backup. If the transaction logs are not
	available, you can still update the IDB by importing all media used since
	the last IDB backup. In this case, refer to “Updating the IDB by
	Importing Media” on page 433.
