Air Cleaner User Manual

After you have selected a rootvg volume group to import, you are asked:
Mount filesystems after importing?
Type y or n to indicate whether or not the filesystems in the rootvg volume group
should be mounted after the volume group is imported. When performing some
maintenance tasks, such as checking and repairing the root (/) or /usr filesystem,
you would not want to mount the filesystems at this time.
After you make your selection, the rootvg volume group is imported, the root (/)
and /usr filesystems are checked and repaired if necessary, and then all filesystems
are optionally mounted. If you chose to mount the filesystems, you are then asked:
Do you want to rebuild the boot logical volume now?
Type y or n to indicate if the boot logical volume should be rebuilt using the AIX
bosboot command. Doing so can recover from many operating system failures but
causes no harm.
You are then placed in a maintenance shell (preceded by the “ksh>” prompt. You
can perform operating system commands from this prompt. When ready, use
normal operating system procedures for rebooting the system.
Performing Recovery Installation
A recovery installation will restore only the operating system on the client by
performing the following steps:
1. Import a rootvg volume group.
2. Check, repair if needed, and mount the root (/) and /usr filesystems.
3. Restore the root (/) and /usr filesystem data from the backup media.
4. Rebuild the boot logical volume.
5. Reboot the system.
This process is not intended for updating the operating system on the client. It is
used to restore the primary operating system filesystems from the client’s backup.
It might be possible to restore the data from a backup taken from another machine,
but note that, because only the root (/) and /usr filesystem data is being restored,
there might be incompatibility with other data in the rootvg volume group.
After you select this option, the LVM information is read from the backup media
and you are provided a list of physical volumes that exist on the system and a list
of logical volumes that reside on those disks. You must select only one physical
volume containing the root (/) and /usr filesystems to be restored. Some systems
might have more than one rootvg volume group.
It is important that you select a physical volume containing a rootvg volume
group. SysBack cannot determine which disks have a rootvg because the volume
group information does not include the name of the volume group. However, you
should be able to determine the rootvg volume group by looking at the list of
logical volumes contained in the volume group.
After you select the rootvg volume group to use, the volume group will be
imported. You are then asked:
