Thanks Tarhon. Pvscan doesn't show /dev/hdc2 at all. Does pvscan only
work on mounted drives?
[root at moe ~]# pvscan
PV /dev/hda2 VG VolGroup00 lvm2 [74.41 GB / 32.00 MB free]
Total: 1 [74.41 GB] / in use: 1 [74.41 GB] / in no VG: 0 [0 ]
[root at moe ~]# lvscan
ACTIVE '/dev/VolGroup00/LogVol00' [72.44 GB] inherit
ACTIVE '/dev/VolGroup00/LogVol01' [1.94 GB] inherit
Thanks,
Mike
