- We have: a H-P 9000/835, HP-UX 8.0, a SCSI card, and no adequate backup
- device. We also have a SCSI DAT cartridge drive (H-P model C1520A) and I
- wanted to attach it to the 835. Granted that the C1520A is not on the list
- of officially-supported devices, but I dont see the point of having a SCSI
- standard if conforming devices cannot communicate.
-
-
- The drive belongs to another machine; on that machine it does work. So I
- did the following:
-
- shutdown, switch off, attach drive to SCSI bus, switch on, (CPU last),
- rebuild kernel by:
-
- SAM --> view/modify kernel --> tape drivers -->
- This offered the choice of a 79xx driver (tape1) I said NO
- or a SCSI driver (tape2) I said YES
-
- perform task --> exit task --> rebuild kernel --> exit SAM & reboot, then
- do insf -e then reboot again.
-
- Then SAM --> peripherals --> tapes --> view
-
- finds the new SCSI tape at address 4.3.3.0 with driver tape2 as well as the
- previous old cartridge drive at 4.5.3 with driver disc1. Selecting the SCSI
- drive and doing "view dev files" finds several entries in /dev/rmt and in
- dev/mt .
-
- Now I want to backup files onto this drive, so I did:
-
- sam --> backups --> backup interactively
-
- If I enter /dev/rmt/0m into the space for the backup device, I get an error:
-
- "this device file has no physical device associated with it." If I move the
- cursor into the space for the backup device and type the HELP key, I get:
-
- examining device at 4.0.0
- 4.3.3.0
- 4.5.3
-
- and the only choice the Help will offer is /dev/rct/c1d0s2 at address 4.5.3
- (again: this is the old cartridge drive, and not large enough for a full
- backup). 4.0.0 is the disk drive and 4.3.3.0 the DAT drive that I want to
- backup on.
-
- Backing up by using /etc/fbackup also failed.
-
- /etc/fbackup -f /dev/rmt/0m -i /
-
- This ran for some time, printing various messages as if it were assembling
- a backup file then failed with:
-
- fbackup: could not open output file /dev/rmt/0m
-
- I believe the SCSI card in the 835 is OK because we connected an optical
- disk drive & it worked. There is only 2 metres of visible cable + maybe 1
- more of internal length in the SCSI devices.
- The manual (Installing peripherals Vol.1) is unhelpful. Please does anybody
- know what is wrong? I ran some simple commands to try to see what is wrong:
