SolutionThe script runs frecover which is a restore utility not a backup. May be the script tries to identify the tape using frecover and there is a problem with the tape but without seeing the script we can not tell.

Re: frecover(5412): Do you wish to try to salvage
What Device/Media you are using for restoration?
As per your log it seems that there is media/cartridge error. That may be a wrong cartridge/tape or may that media is corrupted and not readable.
please crosscheck with below options,
1. check other backed-up media that is working properly in this device or not?
2.once try to clean this drive and then try frecover on same media.
3. if possible it will be better if you can try this media to restore with any other device or server and see what is the result?

Re: frecover(5412): Do you wish to try to salvage
Hi Vinay,
Hope you are taking tape archive (ignite). can you try once to take manually by make_tape_recovery command and check it is successful or not. if required please try on new media also.
if successful then please check your script and modify it accordingly.
if you are not much aware about the script then better you take help with concern person at your site who is aware.
Thanks.

It seems to be going into the fbackup/frecover path and not make_tape_recovery.
What's in $RUN_LOG, /var/opt/patrol/backups/run_SYSTEM.log?

Re: frecover(5412): Do you wish to try to salvage
echo "Running SYSTEM backup" >> $LOG 2>&1
/usr/sbin/fbackup -n -f $TAPE -g $GRAPH -I $DIR/tape_index >> $LOG 2>&1
if [ $? -eq 0 -o $? -eq 4 ]
then
/usr/sbin/frecover -f $TAPE -I $DIR/index.SYSTEM
else
print...
The intent of the script is to run fbackup and then use frecover to extract the index from the tape for verification.
However the $? that is saved is not the exit code of fbackup but the exit code of the append operation, >>, which is always successful.
So fbackup failed and frecover could not find the index on the tape.
Two thing wrong, bad tape and bad login in the script when checking the exit code $?
(I wonder why you used more and scrolled line by line to display the script)

Huh? The exit status comes from fbackup, AFTER the shell redirects the output.
(This isn't a multiple stage pipeline.)
