6. Change the Volume Group, Logical
Volume and Filesystem Settings
The options described in this chapter are only for AIX clients.
This section describes the process of changing the volume group, logical volume, and/or filesystem information
retrieved from a backup before using the option to
Recreate Volume Groups , Recreate Logical Volumes or
Filesystems , or Reinstall from a System Backup .
The physical volumes (disks), volume groups, logical volumes and filesystems defined on the backup are
compared against the current system’s hardware configuration. If there are problems that would prevent the
backup from being installed onto the system, such as missing disks or disks that are too small to contain the
backup data, a list of messages indicating the problems will be displayed and the user will be required to either
make changes manually or must select to automatically fix any problems that are non-fatal.
Non-fatal errors are those that require changes to the logical volume configuration that will allow the data to be
restored, although all of the logical volume features may not be the same as on the original system. For
instance, if there is only one remaining physical volume that matches the original system configuration for a
particular volume group, any mirroring and/or striping will need to be disabled for the logical volumes in that
volume group since these features require at least two physical volumes. If such non-fatal errors occur when
checking the system information, you will be provided the option of automatically fixing the errors. You may also
change the volume group or logical volume information manually to either add more disk space or change other
logical volume attributes manually that would allow the logical volume to be created as desired.
The Change Volume Groups & Logical Volume Settings
Menu
When selecting to Recreate Logical Volumes or Filesystems or Recreate Volume Groups from the SBAdmin
interface, or when selecting to Change Volume Group, Logical Volume or Filesystem Settings when installing
from a System Backup , a screen similar to the following will appear:
The screens shown below are the color versions that will appear when you are using
either a color ASCII terminal or when displaying the options from the administrator
application. If you are using an “lft” console, the options will appear in black and
white as the LFT driver does not support color terminal applications.
