Tape drive disappears
We have two MSL6030 connected into two u320e cards.
The drive and libraries are detected in the BIOS and within Windows. We are running NetBackup 6.5 a few backups will run then the eventlog will show errors for the express2 driver: The device \Device\Scsi\express21, is not ready for access yet.
And a tape drive will have gone missing from the Device Manager.
Any suggestions?

Re: Tape drive disappears
is the RSM servie running? If yes, set it to "disabled". Try a firmware and driver update, and check the cabling and the termination. Is it always the same drive, that disappears?
Best regards,
Patrick

Re: Tape drive disappears
Also check for the Firmware of the Drive. You can check it with the L&TT tool, from www.hp.com/support/tapetools

Re: Tape drive disappears
maybe also u320 fc/scsi mapping should be checked for the correct host to drive assignments

Re: Tape drive disappears
The lib drives are SCSI. The e320e card is a FC/SCSI router. If you install the new host, its HBA port wwns are not assigned to the library SCSI drives (they are missing from the port 0 map), therefore the host does not see them. You should check the port 0 map and add/assigned the hosts HBA port wwns to the appropriate library drives
