Master Server Disk Recovery
Recovering Master Server When Root is Lost
This procedure assumes that the root file system has been lost along with all other files on
the system disk. Figure 2 illustrates the procedure.
The recovery method described here reloads the operating system on an alternate boot
disk and boots from this disk during the recovery. This lets you recover the root partition
without risking a crash due to overwriting files that are being used by the operating
system during the restore.
Figure 2. Recover Master Server When Root is Lost (overview)
1. Load the operating system on the alternate boot disk, using the same procedure as
you normally would for the server.
2. Create, on the alternate disk, the partition and directory where NetBackup and its
databases resided on the original disk. By default, they reside under /usr.
4. Restore root partition
5. Restore /usr/openv/netbackup
6. Restore /usr/openv/volmgr
7. Restore all other files
8. Copy NetBackup databases from
the alternate disk:
/usr/openv/netbackup/db
/usr/openv/volmgr/database
