Trouble with DLT

Verónica Muñoz Segovia — Wed, 09 Aug 2000 21:44:19 GMT

I installed an external Compaq DLT in a HP9000 Class J210 Server and when I enter to SAM in Backup and Restore I got the next message:

"The error handler has gotten the error code 1 of type NOTE with the associated strings
8/12/5.2.0
DEC DLT2000 15/30 GB

What kind of error is this? What am I need to correct in order to can use this DLT to backup?

Regards,

Veronica

Veronica,

Please make sure "stape" Driver is loaded in the Kernel.
I am affraid the DEC DLT 2000 may not be supported on HP 9000 systems. Please check this with HP.

Bad news, the dlt drives from compac have special firmware. Thats why you cannot get a non compac dlt to work on a compac machine.

firstly I would recommend you install th elatest patches for SAM, fbackup and SCSI, plus any dependencies they list.
The second recommendtaion is to check the file:
/usr/sam/lib/C/pd_devinfo.tx and see if there is a reference in there to the device as it shows up in an ioscan output.
If not, try adding an entry to reflect the device, and try again.

I have tried this myself recently using a Compaq DLT2000. It just will not work on an HP. Some firmware commands are simply not available which HP-UX expects to use in order to talk to the tape drive. I gave up, I think your out of luck. In the end ive attached it to a PC running Linux and it works fine!

SAM backup and restore will call fbackup/frecover.
fbackup is able to check for supported tape drives, ie, tape drives with HP firmware. To get around this check you can use, fbackup from the command line, specifying the hostname of the machine:device file of the tape drive.

for example
fbackup -f localhost:/dev/rmt/0m
Try using another backup routine, tar or cpio
if they fail then the tape drive is not compatible.
