Patch set on top of previous 6 sent in earlier. Patch 1 corrects a change to spc_illegal_op() where I added a heap of code to dprintf() the SCSI op code. I've moved this code into its own routine dump_cdb(). Patch 2. Implement MOVE MEDIUM op code. Allow mtx (or NetBackup's 'robtest' utility) to move media between slots.
