The autoleveling feature enables you to automatically update firmware on all Fibre Channel (FC) tape drives that are connected to I/O blades. This allows you to keep all FC tape drives of the same type at the same firmware level. Tape drive firmware is verified whenever a tape drive is reset, such as when the library is power cycled or rebooted, or whenever a tape drive is added or replaced. If the firmware does not match, the tape drive firmware is autoleveled.
FC tape drives must be connected to an I/O blade to participate in autoleveling operations. The library does not support autoleveling FC tape drives connected directly to an FC host or switch. In addition, the library does not support autoleveling SCSI or Serial Attached SCSI (SAS) tape drives.
To enable autoleveling, you must upload a firmware image file to the library. If you have multiple versions of FC tape drives installed in your library (for example, LTO-3, LTO-4, and LTO-5), you must upload a unique firmware image file for each version. For instructions on uploading tape drive firmware used in autoleveling, see Uploading Tape Drive Firmware Used in Autoleveling.
You can delete a firmware image file when you no longer want to autolevel tape drive firmware. For instructions on how to delete firmware, see Deleting Tape Drive Firmware Used in Autoleveling.
