18. Recreate Volume Groups, Logical
Volumes or Filesystems
The options described in this chapter are supported for AIX systems only. Due to the
complexity of Linux and Solaris configurations, allowing creation of devices onto
other devices (i.e. meta-disks on logical volumes or ZFS volumes on slices, etc), this
features is not available for Linux or Solaris at this time.
When to Use These Options
Due to various system problems, it may be necessary to recreate a filesystem or even an entire volume group
that had to be removed from the system due to a failed disk drive or other problem. Since changes frequently
occur to the system configuration, such as the expansion of filesystems, and moving or striping of logical
volumes across disks, it is often not known the proper sizes and locations of the logical volumes and
filesystems needed to restore the data properly. However, this information is stored on the backup media and
can provide an automated way of recreating the volume groups, logical volumes and filesystems exactly as they
were previously without prior knowledge.
Use one of these options to recreate the volume groups, logical volumes and/or filesystems into which you will
later restore the data using the option
Restore Data from a Backup .
It is sometimes also desirable to replicate a volume group configuration from one system onto another. This
option will allow you to use the information stored on a backup to create or recreate volume groups, filesystems
or logical volumes on another system, while changing the locations and sizes of the filesystems and logical
volumes to accommodate the new system.
In addition, a volume group or logical volume may be recreated on the same system from which it originated,
even if the original volume group or logical volume still exists. This is handy for being able to restore prior data
to the system and still keep the current copy available. This is accomplished by assigning a different volume
group or logical volume name(s) to the new volume group or logical volumes created.
Important: This is the only option in the SBAdmin Interface that must run a user
interface on the client (although the client system need not have a graphical display).
In order to have the user interface (which is running on the client) display on the
admin system , the client must have AIXwindows installed. If AIXwindows cannot be
found on the client, an appropriate message will be displayed and you may not
continue. You must either install AIXwindows on the client or rebuild the volume
groups, logical volumes or filesystems manually on the client.
Recreate Volume Groups
To recreate volume groups, you must have an accessible a System Backup containing the desired volume
groups you wish to create.
To recreate a volume group, perform the following steps:
1. Select Actions "Recreate Volume Groups from the menu bar. A screen similar to the following will
display:
