HP recently shipped us a P212 SCSI RAID card; this was chosen for our new Quantum tape drive. After a week of fighting with it, we tried an alternate SCSI card (non RAID) at the suggestion of Quantum, and Voila, all problems disappeared. Quantum claims (perhaps true, perhaps not) that some of the SCSI RAID cards are not implementing the full generic SCSI protocol and don’t handle having non-disk systems on their bus. So, hopefully Google picks up this HP P212 SCSI RAID card (PN: 013218-001) and anyone else struggling with this will see this!
