Managing the Data Protector Internal Database

Recovering the IDB

Chapter 9

422

• 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
Procedure

To recover the IDB, run the

omnidbrestore -autorecover

command.

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 DCBF
Part

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
Binary Files Are
Missing

DC binary files are organized so that one binary file exists for each
medium. If some DC binary files are missing, media positions of some
media point to the non-existent files. An error message is displayed when
browsing the relevant filesystems. Proceed as follows:

1. From the

omnidbcheck -bf

output, identify the Medium ID of the

missing binary file. Run the

omnimm -media_info

command to get other attributes of the medium, such as medium
