Show Disks with the Same Physical Volume ID
This menu item displays each Enterprise Virtual Array virtual disk and any virtual
disks that have the same physical volume identifier.
Recreate Volume Group
This menu item allows you to recreate the volume group of a virtual disk that has
the same physical volume identifier as another.
1. Open the snapshot utility and choose Recreate Volume Group.
2. Choose the virtual disk from the list of presented disks.
The utility changes the physical volume ID on the disk, issues the
recreatevg command on the disk, and then mounts any filesystems on the
disk.
The new volume group name is in the form of sX_<old volume group name>,
and any of the filesystems are mounted in the directory /snapX.
Table 2 displays an example of how the recreated volumes are named and
mounted.
Expanding Volumes
You can increase the volume size of the virtual disk with Command View EVA.
You simply change the size parameter in the particular virtual disk’s property
page.
IBM AIX does not support dynamically growing a virtual disk volume. If you
need to increase the size of a virtual disk, use the workaround that follows:.
Note: As with any large-scale operation, it is always best to first create a backup of
your data.
