If you would share your knowledge with us, we might be able to help you recovering your system without restoring from backups - since it is apparently NOT a failed disk?

Anyways, you should be able to restore a plain rootvg onto your spare disk and than import the 'old' rootvg under another name / VGID ... AIX will rename the logical volumes but if you recreate the empty mountpoints, you should be able to mount the filesystems manually.

Kind regards

volunroot(8)						      System Manager's Manual						      volunroot(8)

NAME
volunroot - Remove Logical Storage Manager hooks for rootable volumes SYNOPSIS
/usr/sbin/volunroot [-a | -A] OPTIONS
Specifies that all volumes on the system disk be converted back to UNIX disk partitions, not just the root and swap volumes, rootvol and swapvol. Forces removal of the private region unless it is the last one in the system. DESCRIPTION
The volunroot script can be used to restore the accessibility of the root, swap, and other file systems on the boot disk directly through disk partitions instead of through volume devices. The script also removes other changes that were made to enable booting of the system from the root volume, so that the system will boot with no dependency on the Logical Storage Manager. When used with no options, volunroot affects only the root and swap volumes, rootvol and swapvol. For volunroot to work properly, only one plex must exist for each of the affected volumes. This plex must be the one created by volrootmir or the original plex created when the root disk was encapsulated. This ensures that the underlying subdisks will have equivalent partitions defined for them on the disk. If these conditions are not met, the volunroot operation fails and none of the volumes are converted to disk partitions. The unwanted plexes can be removed using either voledit or volplex. SEE ALSO
