Error when running make_recovery ?

[Scott Dunkley]

I am running:

make_recovery -A -v -d /dev/rmt/0mn

and as it tries to right he LIF to the tape it fails with the following error.....
make_recovery(472): /usr/bin/dd failed,res=512,errno=0
Cleanup

Can anyone tell me what this means please, I assume dd is failing but dont know why ????

most usually this is a bad tape or tape drive. can be that the tape drive needs cleaning. also can be the corrupt device files.

test yourself using a normal dd on the command line to that tape.

also could be patch issue where you need scsi patches. check for latest ones on the patch database here.

Thanks, I think it is a dodgy drive, i have tried cleaning it several times, and it works fine on another machine with a different dlt drive.....thanks again!!!!!!

For what I can tell, it looks like either bad media or a problem with your device files. Call #AA5745602 recommends the following:

You are getting this error because you either have a defective media,
or a defective tape device.

Use these steps to isolate your problem:

A. Verify the 'dmesg' entry.

B. Execute the 'insf -e' command.

C. Use a new 120 meter tape.

D. Execute the 'dd if=/dev/dsk/c.. of=/dev/null bs=1024k' command.

Hope this helps.
