Manual Disaster Recovery of an UNIX Cell Manager
Chapter 10 513
• A device connected to the Cell Manager.
Procedure The following steps need to be performed to recover a Cell Manager:
1. Replace the crashed 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 that you cannot restore the database directly. See
Chapter 6, “Restoring Data,” 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.
