Running NW 7.5.2 with Data Domain DD880 in VTL mode. It has been suggested by DD that we need to relabel tapes each day via a script in order to keep the data stored on the DD880 trimmed down for replication, and I will agree thats probably a good idea. I have a script written that works pretty well. The problem comes in if that script is running against a pool when a backup kicks off that wants to use the same pool. Some of the relabel commands may fail, and then that tape may be "stuck" in that drive, and that drive can't be used until I can get that tape out. The only way I get the tape out is to go to the DD880 and export those tapes, then import them back into the library. Here's a sample of 2 that got stuck today because oracle backups kicked off in the middle of this process:

OR0073 from oracle8daycdl on JB DD880456-1 will be re-labeled
setting verbosity level to `3'

My question has 2 parts I guess, is there a problem with my script? And is 
there maybe a better way to do this? Here's my script:

#!/bin/ksh

# Program Name: recycle_tapes_J1.sh

#First, get a list of all tapes marked recycled and output to a file we will

mminfo -q "!inuse,volrecycle,location=$LOCATION" -r "volume, pool, volretent,

do

#WORKINGLOOP - delete and relable volumes

        mminfo -q "volrecycle,pool=$POOL,location=$LOCATION" -r volume | while 
read VOLUME

        do

        echo "$VOLUME from $POOL on JB $LOCATION will be re-labeled"
        echo "$VOLUME from $POOL on JB $LOCATION will be re-labeled" >> 
recycled_tapes_NT2LEGATOJ1.txt

        nsrjb -Yvvv -j $LOCATION -R -b $POOL -L $VOLUME

        done
done
