Upgrade Guidelines 0 Before upgrading StorNext, review the following upgrade guidelines:
• Before upgrading, make sure there is no I/O activity. On the StorNext home
page, the number of store candidates should be 0. For tape drives, make sure
no media is mounted and no read/write operations are being performed. If
there is I/O activity, wait for the I/O activity to complete before upgrading. If
you attempt to perform an upgrade during a period of high activity, the
upgrade may fail.
• Before upgrading, Quantum recommends reviewing system configuration
settings and performing a backup procedure to back up StorNext
configuration files.
Note: Quantum supports upgrades only from the previous two
major releases of StorNext. For example, you can upgrade to
StorNext 3.5.1 from version 3.1 or 3.0, but not from version 2.8
or earlier.
