when you use nsrjb -w to 'withdraw' the tapes from the jukebox  the location 
will be blanked.   that is enough to stop them being requested for  backups... 
but you should mark them all as full, and manual recycle to avoid any of them 
being written to while in the library for restores.   also nothing wrong with 
putting the write-protect tabs on just to make sure....  (so long as you have 
version 7 at least...).

Subject: [Networker] Changing the tapes, use mmlocate ?


Greets.

You know, I'm a slack tape operator. I'm not sure that's something 
people are willing to publicly admit but I'm going to step right out 
there and say it. I tend to run my LTO-2 tapes to the point where I know 
it's time to change them when I start seeing read errors on test 
restores. Manufacturer tape change recommendations, what are those? 
Being slack and not changing tapes often is why I have to ask the 
following...

That said, can someone confirm for me that in my 4560 IBM Tape Library 
(4 drives, 60 slots, has barcode reader)

1) Unload all tapes using nsrjb -u
2) Use mmlocate to set the location of all tapes to something like 
"dusty_box_shelf_6"
3) Remove the physical media and insert the load the new media
4) Use nsrjb to label all slots

My goal is to prevent Networker from asking for the old tapes. Should 
they be set to "full" first or is using mmlocate good enough to let 
Networker know that it shouldn't ask for the tape during future backups

Thanks for the advices, sorry for the basic question.
