We just installed a new HP MSL4048 Tape Library with 2 HP Ultrium 6-SCSI Tape drives. We are using a mixture of LT0-4 and LTO-6 backup tapes. Our backup server recognizes the Tape Library (Medium Changer) and the 2 Tape drives. Our backup server uses Symantec Backup Exec 2012 and for some reasono it's recognizing the LTO-4 and LTO-6 tapes as cleaning tapes. I have done the following trouble shooting steps so far:
1. Power down and powered up both the backup server and the Tape Library.
2. Cannot successfully run a backup job because all the backup tapes are being read as cleaning tapes.
3. Check the settings and properties in Symantec Backup Exec 2012 software.
Any ideas why this is happening?
