Chapter 15: Maintaining Your Library
Maintenance Actions
Caution: Before you update drive firmware during this procedure,
make sure that tapes are not mounted in any of the drives.
If tapes are mounted in drives during the update process,
the library loses knowledge of the cartridge home cell in
storage, resulting in library and host inventory issues.
If you load a firmware image onto a drive that is the same
version that is currently running on the drive, the upgrade
will fail.
If host reservations exist on drives, it will fail the upgrade.
1 On the Update Drive Firmware dialog box, select Firmware Image.
