HP-UX 11 - SIOC_INQUIRY when running diskinfo

Posted on 2009-12-19

Hello Everyone!
        We recently removed a few disks from an HP-UX server, however they are still showing up when running an ioscan -fnC command.  Here is what we have done:

1. Remove all volume groups and associations with the disks
2. shutdown server
3. Removed LUN association on SAN
4. performed ioscan -fnC (disks still show up as "claimed")
5. removed special files using rmsf 'path to special file'
6. rmfs -H 'hardware path'
7. reboot

From our understanding, the disks should now be gone from HP-UX.  The strange thing is that the disks still show up as "Claimed" when we run an ioscan -fnC, but there are no associated special files.  If we do a diskinfo of the disks, we receive a message that states "SIOC_INQUIRY."

We have tried adding in new disks (we rebuilt our RAID group for RAID 1/0 instead of RAID5) but they are not accessible as the system appears to see the old disks still.  I am not the Unix admin for our company, but I am trying to assist him.  I would appreciate any assistance you can provide!  Please let me know if any further information is required.

    We resolved this issue, it turns out Unix was not the problem, we had powerpath installed and it was causing our issues.  We issued a powermt -check command to clean up the entries and this resolved our issue.
