I have some LTO tape drives, and use cleaning tapes as required, but the lifetime of the cleaning tapes is not as predictable as I would have expected. I'm looking for a way to query the system, whether it be the robot (Quantum i6000) or Veritas Netbackup to see if the tape has actually expired.
Honestly I'm not exactly sure what causes a tape to be expired -- I'd assume it winds to the end and stops, so it doesn't reuse a previously used section. Currently Netbackup is storing the number of "available cleans" in the "number of times mounted" field, which always starts out at 50, but I've noticed cleaning tapes can expire after as few as 15 cleaning cycles, perhaps for a particularly dirty drive. Thanks.
