Preparing to Upgrade Clustered Controllers (BUI)
Use the following procedure to prepare to upgrade clustered controllers.
Before You Begin
Complete Preparing for a Software Upgrade.
Note - For the purpose of this procedure, the first controller to be upgraded is referred to as controller A and its peer 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. If both controllers in a cluster have active resources, choose either controller to upgrade first.
-
On your local system, download the software update as described in
Checking for and Downloading Software Updates (BUI).
The update package 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.
-
On controller A, go to Configuration > Cluster and check the active
resources and status of each peer.
For information about the cluster states, see Cluster Takeover and Failback in Oracle ZFS Storage Appliance Administration Guide, Release OS8.7.0.
