A suggestion I was given, but TSM support I think, was after changing
ANYTHING on a drive...microcode...upgrades...whatever...always do an UPD
DRIVE command against each one. TSM communicates with the drives and keeps
track of the capabilities reported. All this does is refresh TSM's
information. Now, if you delete the drive and add it back in you're OK.
You can see some of this information with the SHOW LIBRARY command.
