Upgrade to 4.1.0

These instructions explain how to upgrade to Appliance Controller 4.1.0 from 4.0.0. Older Appliance Controller releases are not supported for upgrades to 4.1.0.

If you are upgrading from a release prior to 4.0.0, download an offline version of the documentation for the release you are upgrading to from the Documentation Center Downloads page BEFORE upgrading to the current Appliance Controller release.

Note: Upgrades can last up to 5 minutes depending on several factors, including if Samba is upgraded, and if the node is part of a NAS cluster, during which client connections to NAS shares, if configured, are interrupted. Quantum recommends scheduling the upgrade during off-hours to minimize the impact of these interruptions.

Beginning with Appliance Controller 4.1.0, the qxsarray and qstorage commands are no longer supported. If you experience an issue as a result of the removal of the qxsarray and qstorage commands, contact Quantum Technical Support (see Contacting Quantum Support).
