HP Data Protector A.06.11 Recovery Manual page 131

Prerequisites
You will need the following to successfully perform a disaster recovery:
• Media containing the last valid known backup of the root partition of the Cell
Manager and IDB.
• A device connected to the Cell Manager.
The following steps need to be performed to recover a Cell Manager:
1. Replace the affected disk.
2. Boot your system from the installation media of your operating system.
3. Reinstall the operating system. Refer to your system administrator's manual for
instructions. During the installation, using the data gathered during the
preparation phase (pre-exec script), re-create and configure the physical and
logical storage structure of the storage, logical volume structure, filesystem and
mountpoints, network settings and other.
4. Reinstall the Data Protector on the Cell Manager.
5. Restore the latest backup of your database and /etc/opt/omni to a temporary
directory. This simplifies the restore of all other files from media.
NOTE:
You cannot restore the database directly. See the online Help for instructions.
This includes stopping all Data Protector processes with the
/opt/omni/sbin/omnisv -stop command. This ensures that no files
will be in use.
6. Remove the /etc/opt/omni directory and replace it with the /etc/opt/omni
directory from the temporary area. This re-creates the previous configuration.
7. Start Data Protector processes with the /opt/omni/sbin/omnisv -start
command.
8. Start the Data Protector user interface and restore all the files used from your
backup.
9. Reboot the system.
Your Cell Manager should now be successfully recovered.
