I have a server (SUSE 11.5) that has two disks. There is only one volume group (vg01). How do I determine the physical device on which that vg exists?

By physical device, what do you mean? A volume group can correspond to multiple disks or partitions. Do you want them all? – Faheem Mitha Mar 22 '11 at 19:13
I guess it was poorly-worded, but yes, all of them. Your answer was what I needed - thanks! – swasheck Mar 22 '11 at 19:22

I think

# pvdisplay

shows you the physical device(s) corresponding to all your volume groups.

Inter alia, my system shows, for example

--- Physical volume ---
  PV Name               /dev/sdc6
  VG Name               olddebian
  PV Size               186.26 GiB / not usable 638.00 KiB
  Allocatable           yes 
  PE Size               4.00 MiB
  Total PE              47683
  Free PE               5443
  Allocated PE          42240
  PV UUID               QcpaYU-GuWX-ssIl-U2i9-26Cq-QhQf-fgOyD4

This is the only one of my VGs that corresponds to a raw partition. The others are on top of software raid devices.

@swasheck: In addition to pvdisplay showing a lot of information, there is pvs with compact output. Similarly there are vgdisplay and vgs for volume groups and lvdisplay and lvs for logical volumes. – Gilles Mar 22 '11 at 20:29
@Gilles: yes, pvs is better for this question. – Faheem Mitha Mar 22 '11 at 20:37
@Gilles. I'd stumbled across those commands while searching for this answer, but thank you. They will be most helpful for what I need to do, now that I have the initial requirement satisfied. – swasheck Mar 24 '11 at 12:35
