It is also a good idea to capture a library snapshot information before
making any significant change to your system such as upgrading library
firmware. Technical support personnel can, if necessary, use the snapshot
file to troubleshoot the library. For more information, see
Snapshots of Library Information
Caution: If you are currently running library firmware version
320G.GS004 or 400G.GS006, you must first install and run
the Library Service Utility before upgrading firmware. If
you do not first run the Library Service Utility, then the
firmware upgrade may not complete successfully. The
Library Service Utility and installation instructions are
located in the ".zip" file that contains the firmware
download files.
If you are currently running library firmware prior to
version 320G.GS004, do not upgrade to version
320G.GS004 or 400G.GS006, but instead upgrade to the
latest version. You will not need to run the Library Service
Utility.
Note: If you downgrade from one major firmware version to an
earlier major version, library configuration settings will be
reset to the factory defaults. You can restore the other
configurable items using a configuration file that was saved
when the earlier version of library firmware was installed on
the library, or you can reconfigure your library's settings. For
more information, see
Configuration
Note: If you are running firmware version 400G or higher and want
to downgrade, the following restrictions apply:
• If your library is Quantum branded, you can downgrade to
version 400G or higher (there is no lower version of
Quantum-branded firmware).
• If your library is ADIC branded and has FC I/O blades
installed, you can downgrade to version 400G or higher.
Firmware versions 320G and lower do not support FC I/O
blades. If your library does not have FC I/O blades, you can
downgrade to a lower version of firmware.
