Before you can update the library with a library software update file, you
must use the Update Software Wizard to download the file to the MCB.
You can use the Update Software Wizard to perform the following
operations:
• Install new library software (inclu
ding downloading and installing
software)
• Reinstall the currently installed library software package
• Roll back library software to a previously installed package
You can perform all update operations while viewing the physical library.
However,
if you are viewing a partition, the only operations that are
available to you is updating drive firmware (by using either firmware
images or update tapes) for drives within the partition.
You can perform update operations from e
ither the library’s touch screen
or a remote client on a remote host computer, with one exception. You
cannot download images form the local touch screen.
During the software update process, the MCB distributes the various parts
of the sof
tware package to the proper library components. The MCB also
keeps track of the software components it updates so that you can roll
those components back to a previous version.
After the library finishes installing new library software or rolling back
li
brary software to a previously installed level, the library automatically
restarts. Any necessary autoleveling of library components begins after
the library powers up and discovers library components.
As a result of restore, rescue, or revert operations,
the library shuts down. You must have physical
access to the library to bring the library back up.
If you are performing a restore, rescue, or revert
operation using remote access, the library will
remain shut down until the library is directly
powered back on.
If you choose to reinstall the currently installed software package, the
robotics control unit (RCU), picker, and drive sleds are updated.
Therefore, the library does not restart after the reinstallation process
completes. The reinstallation procedure should be run only under specific
circumstances. For more information, see Rolling Back to the Previous
Build Package on page 395.
