You need to determine if it's one or all media servers having a problem with dismounts. The most common cause of unload failures is device mapping mismatch (when ACS address e.g. 0,0,10,0 does not map to the correct /dev/rmt/xcbn device name).
If logging is increased on ACSLS side, you will be able to see all mount/dismount requests in acsss_stats.log. If you have VERBOSE entry in vm.conf on all media servers, you will be able to see the NBU part of Media Manager comms as well in /var/adm/messages.
