I have NB 6.0 mp4 Master/Media/EMM running on W2K3 sp 2 server. Made month
end tape standalone for off-site storage and ejected from SL500 libray. Tapes
are LTO3 Ultrium RW 800GB. Put new blank tape with custom barcode label into
library and ran inventory: update volume configuration(no bar code or meida
id rules, using default).

Tape removed for off-site storage: Media ID is CAS031 and Bar Code is CAS031
New Blank: Media ID is CAS031 and Bar Code is CAS032

Unable to re-label, erase or un-assign volume pool. Any help greatly appreciated.
