Hello,
Please note the output of nsrjb, tapes & inquire cmd, check the tape 
numbers in registry and reboot the server and redo the cmd to see any 
thing changed,i.e drive order, do you have the drives FC attached ? have 
you enabled persistent binding on the Tape lib & also on windows server ?
Since you only have two drives, it may just be easy to mount couple of 
tapes in them and do unmount cmd from networker  nsrjb -f \\.\Tape0 for 
example ( or use GUI)  & see which tape drive is actually getting 
unmounted, if it's not the one you just issued the cmd for them you have 
drive mismatch. ( mt cmd can also be used for drive verification).All 
backup activity should be stopped first.
You can user nsrjb cmd to reconfigure  the tape lib or use GUI to 
reconfigure, remember to note down your jukebox values if you have 
changed, i.e timers & pools etc before you delete the tape lib ( i would 
try  rebooting backup server  first)
HTH

Hi Paul,

Thanks for that. The fact that the drives keep changing to not write 
enabled are a good indication of this. Can you remind me of the networker 
commands I need to run from the CMD prompt to delete and re-create the 
jukebox?


Thanks.
