DAT72 backup failed??

[Richard Bordignon]

Used INSF -e option and now the tar command works on the new tape drive. In using SAM fbackup I get the following error.

"Fbackup Output"

Shalom,

The default device for backup fbackup uses is not there or you chose the wrong one.

There is a choice with sam based interactive backup, so perhaps choose something that is present.

ioscan -fnC tape

Hi,

perhaps a problem with special file if a other tape has been installed before

What version of HP-UX are you using? The DAT72 is relatively new and you may not be able to get this to work with fbackup on 10.20 or earlier. Check your available device files with:

insf -knfC tape

Note that many of the device files in /dev/rmt are duplicates with short and long names. For fbackup, you can just use the short name (0m 1m 2m 3m, whatever). fbackup does have some internal code that knows how certain models of tape drives work (whereas tar does not) so a patch for fbackup may be needed.

Hi Richard,

Systems with DAT72 drives need the newest stape patch ([PHKL_29247/PACHRDME/English] for 11.00
or [PHKL_29248/PACHRDME/English] for 11.11) for such drives to be recognized and usable.

Check if this is available if not pls update I guess this should resolve the issue.

Best Regards,
Prashanth

Explanation of the error message is that the device is not recongnisable by fbackup.Confirm the device name being used by fbackup with that of manual tar command.
Refire the fbackup from command line by specifying exclusively the device name.

HTH and more informative
