Fbackup Errors

[Mel_12]

Hi,
I just installed HP SureStore DAT24 without any proper refrence manual; just blindly. I re-activated my old script that worked before my last backup drive died. Well, here is the errors. Please help anybody.
Thanks
Mel

did you try to replace the tape with brandnew(neverused) one?

I'd suggest that you verify that the device file exists, and relates to your tape drive

ll /dev/rmt/0mb
ioscan -fnCtape

If this is OK, clean the drive, and try the backup again with a new tape.

If it still fails, you'll probably need a new tape drive, so log a hardware call with HP.

Its an HP drive, which is good, and its connected fine because fbackup does actually try to write to the device file successfully, so it must be a tape/cleaning problem. The tape in the drive says its beenused 38 times so try a different, hopefully new, tape, and give the tape a run through with a cleaning tape a few times first. If that doesnt fix it the drive may be faulty - was it working successfull elsewhere before you installed it ?

[Cheryl Griffin]

"fbackup(9999): I/O error" looks like a hardware failure.

New tape, clean the drive, check ioscan and for the SCSI/tape patches, test the drive with dd or tar. Check the syslog for errors.

Thanks guys. The problem was resolved by simply selecting one of the device names that SAM listed and replacing the device name in my script with this name which ended with BEST. (/dev/rmt/BEST). If anybody could tell me how to revert to the device name on my script which was /dev/rmt/0mb , that would be great. A detailed explanation on how the system named the backup drive to /dev/rmt/BEST would be appreciated.

Thanks
Mel
