Manual Disaster Recovery of an UNIX Cell Manager

 

•

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

 

 

-stopcommand. 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

 

 

-startcommand.

 

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.
