Rebuild the operating system in the event of a disaster.
Before You Begin
- Ensure that the destination client is same as source client while performing a disaster recovery.
- Make sure to Install the Linux Operating System on the system that you want to restore. Make sure to install the Operating System exactly as it existed prior to a hardware or software corruption problem.
For Image Level on Unix Agent:
- The client computer must have a default install partition with the File System iDataAgent installed on it. Make sure to enable the Networking option. The TCP/IP, hostname, and domain name settings of the default install must match those of the system that you are restoring.
- Create and mount a root file system on the system that you want to restore.
Image Level Agent cannot be used for disaster recovery of operating system volumes.
- Type the command to create partitions/slices on the disk.
fdisk [-l] [-b SSZ] [-u] device
- Type the command to create the root file system.
mkfs [-V] [-t fstype] [fs-options] /dev/<hda1> [size]
where <hda1> is the Drive Identifier of the partition where you want to create the root file system.
mkfs [-V] [-t linux] [devfs] /dev/<hda1> 
- Type the command to mount the new root file system at /mnt.
mount /dev/<hda1> /mnt
Where <hda1> is the Drive Identifier of the partition containing the root file system.
mount /dev/<hda1> /mnt
- If any other file systems existed on the root disk before the crash, type the command to recreate them as well.
mkfs [-V] [-t fstype] [fs-options] /dev/<hda2> [size]
- Create an empty directory called "proc" on /mnt .
- If you have recreated any file systems other than root, type the command to mount these as well.
mount /dev/<hda2> /mnt/<file_system_name>
where <file_system_name> is the name of the file system and <hda2> is the Drive Identifier of the partition containing the file system.
- If required, install either the lilo or grub bootloader (per the bootloader that was used in your environment) to the restored disk.
- Exit and restart the computer.
