Filtering issue, while trying to create a volume in Linux
Just pulled in 3 new luns on a Linux system that is using Powerpath 4.5.3. We are up to 37 volumes, listing as emcpowera through emcpowerbb. I am able to see all of the volumes using powermt display dev=all, and I can fdisk the new volumes, however when I try to run a pvcreate of the last two volumes, I get the following error:
Device /dev/emcpowerba1 not found (or ignored by filtering).
Device /dev/emcpowerbb1 not found (or ignored by filtering).
Not sure what filtering file to look at, we check /etc/lvm/lvm.conf removed all of our filter lines, still same issue. Does anyone have any ideas?

Maybe they already have a partition table on them ??
Can you please try to scratch the lun and run pvcreate again ??
# dd if=/dev/random of=/dev/emcpowerba1 bs=1M count=8
If you want you can also try to run pvcrate with "-vvvv" option.. Maybe it will give you better details on why it's failing.
