Hi,

We have a SAN that exports 4 LUNs. These appear as SCSI devices on the server (/dev/sd[c-f]). When I try to create physical volumes on these devices, I get the following error:

#>pvcreate /dev/sdc
 Physical volume "/dev/sdc" successfully created

#>pvcreate /dev/sdd

This happens after pvcreate is run the second time, does not matter in which order. It looks like when pvcreate sets the device id, it somehow sets it for all the devices.


You're sure sd[c-f] is not the same device on multiple paths?


How can I be sure? How do I check?

This SAN exports another set of 4 LUNs to a different server and they work just fine.

pvcreate --version
  LVM version:     2.00.33 (2005-01-07)
  Library version: 1.00.19-ioctl (2004-07-03)
  Driver version:  4.4.0

pvcreate on the server that does not work is a little newer, so I wonder if there was any new code/bug fix(es) since this version that caused a regression.
