During the software update process, the MCB distributes the various
parts of the software 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
library 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.
Caution: 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 re-installation process
completes. The re-installation procedure should be run only under
specific circumstances. For more information, see
Previous Build Package
Note: Rollback and re-installation of current package options are
viable recovery steps during a failed firmware upgrade,
however these features should not be used as troubleshooting
tools.
Accessing the Update Software Wizard
The Update Software Wizard gives you access to all of the library's
software update operations.
Note: Before performing a software upgrade, we recommend that
you shut down and restart the library.
