make way for rootvg. With virtual disks you can resize your volume group on the fly:
Note: this is supported for rootvg and concurrent vgs from AIX 6.1 TL 4. See IBM technote IZ80021 http
I tried to increase rootvg on an LPAR running AIX 5.3 TL 11 and hit the following error:
Looks like the volume group needed to be varied off and varied on again. For rootvg, that means a reboot.
No reboot on AIX 6.1
In AIX 6.1 (from TL 4 - use oslevel -s to check your AIX level), you can increase rootvg on the fly.
Sounds like yet another reason to migrate to AIX 6.1.
