Hello

I do have problem using Linux with an external HP tape drive. The server platform is also an HP Server; the server is an HP ML350 G4, and the Tape drive is a HP Storage Works Ultrium 448 - 1U Rack-mountable.

Tried hp_rescan ? Maybe it's only for SAN-stuff, but maybe it also works in this case.

cheers, Rainer

HP Ultrium documentation says two drivers should be automatically up, sym53c8xx for LSI SCSI interface "st" for tape and /proc/scsi/scsi should contain information about tape drive, e.g. SCSI ID. However none of them happened in my case! (document: "UP LTO Ultrium 2-3 - Unix Config Guide")

The SCSI adapter is an LSI53C1030. The system has another the same adapter which is used for hard disk drives.

The interesting part is, the hard disk are detected and even OS boots from them, but I can't make the tape drive work. Moreover, in system boot up, LSI SCSI BIOS displays informations saying there is a tape drive connected!

the hard disk is apparently running on a CCISS HP SmartArray raid controller of some sort, and is being seen as /dev/cciss/c0d0 . I'm not sure these support tape. Now, if this is the sort of SmartArray raid controller which takes over and manages the other SCSI channels, maybe you have to go into the BIOS (or the SmartArray BIOS) and disable this.

pertinent info from DMESG... I note the 53C1030 is seen as PCI device 02:03 and the CCISS is 0A:04

ah... looking at your LSPCI output...

note those first two are two PCI Functions on the same PCI Slot (actually, I believe that may be an onboard device), while the 2nd two are two seperate SmartArray 6400 cards. I bet you plugged your tape into a SmartArray port rather than a onboard(?) SCSI port. The PCI addressing notation there like 02:03.0 is Bus:Slot.Function

Any one has same experience, suggestion, comments or clues?

I've place a zip file here: http://msarmadi.googlepages.com/report_files.zip which contains:

Mehdi,

did you install the "mt-st" RPM ? This lets you control your tape with the mt utilities.

Knowledgebase articles that seem to be relevant for your case are e.g. http://kbase.redhat.com/faq/docs/DOC-1235 http://kbase.redhat.com/faq/docs/DOC-7084

HTH,

Kay
