I'm running lvm-1.0.8-9 on RHES3 and am receiving the following when I 
try to utilize a volume from an EMC array:
# pvcreate /dev/emcpowera
pvcreate -- invalid physical volume "/dev/emcpowera"

The OS sees the volume fine:
# fdisk -l /dev/emcpowera
Disk /dev/emcpowera: 10.7 GB, 10737418240 bytes
255 heads, 63 sectors/track, 1305 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

I can create a partition and then a filesystem without issue, but I 
really need to use it within LVM.

Any ideas?
