Managing the Data Protector Internal Database

Recovering the IDB

Recovery Procedure

•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.

To recover the IDB, run the omnidbrestore -autorecovercommand.

The command reads the IDB recovery file and if IDB backups are logged to the file, it stops the services and starts restore of the IDB back in place. All the options are generated automatically using data from the IDB recovery file.

Once the restore is complete, the omnidbrestore checks if transaction logs are available to be replayed. If logs are available, you are asked to confirm the replay of the logs. If this step is cancelled or transaction logs are not available, output describes how to update the IDB since the last IDB backup by:

•importing media

•finding the transaction logs and replaying them later

Once you replay logs or import media to update the IDB, the full IDB should be successfully recovered.

Handling Minor Database Corruption in the DCBFPart

If you detect that the IDB corruption is of minor severity, it means that some DC binary files are missing or corrupted. If this is the case, there is no need for complete IDB recovery. You can easily recreate the binary files by importing catalog from media. Choose the recovery procedure depending on the corruption type.

Recovering if DC DC binary files are organized so that one binary file exists for each Binary Files Are medium. If some DC binary files are missing, media positions of some

Missingmedia point to the non-existent files. An error message is displayed when browsing the relevant filesystems. Proceed as follows:

1.From the omnidbcheck -bfoutput, identify the Medium ID of the missing binary file. Run the omnimm -media_info<Medium> command to get other attributes of the medium, such as medium
