Upgrading Software on Clustered Controllers
Upgrading Software on Clustered Controllers
This section describes how to upgrade the system software for an Oracle ZFS Storage
Appliance with clustered controllers. Cluster update is also referred to as a rolling update.
Controllers are upgraded one at a time, and each controller is upgraded while it is not providing
service to clients. A cluster update can be performed using either the BUI or CLI.
Use the following tasks to upgrade software on clustered controllers:
■
Preparing to Upgrade Clustered Contollers - BUI, CLI
■
Upgrading Controller A - BUI, CLI
■
Upgrading Controller B - BUI, CLI
Preparing to Upgrade Clustered Controllers (BUI)
Use the following procedure to prepare to upgrade clustered controllers.
1.
On each controller, go to Configuration > Cluster, and click the lock icon next
to the management interface.
2.
Check the active resources and the status of each controller on the
Configuration > Cluster page.
For information about the clustered states, see “Inherited Properties” in Oracle ZFS Storage
Appliance Administration Guide, Release OS8.6.0.
Note - For the purpose of this procedure, the first controller to be upgraded is referred to as
controller A, the other one is controller B.
■
If one of the controllers is in a Stripped state (it has no active resources), upgrade that
controller first to avoid availability delays. This is controller A.
■
If both controllers in a cluster have active resources, choose either controller to upgrade
first.
3.
On your local system, download the software update.
The update is a single compressed file named with the version number, such as ak-nas-2013-
06-05-0-0.0.pkg.gz. You can rename the file if needed; the version number is recorded within
the image. The updates can vary in size, but are typically several hundred megabytes in size.
4.
On the Maintenance > System page of controller A, click the add icon next to
Software Updates.
