Complete Preparing to Upgrade Clustered Controllers (BUI).

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.

Log in to controller A and failover its resources to controller B by performing a reboot:
1. Click on the power icon in the upper left section of the navigation bar.
2. Select Reboot from the drop down menu and click OK to confirm.
  Do not select Diagnostic Reboot. Wait for the reboot to complete before proceeding.
On controller A, go to Maintenance > System, and click the arrow icon next to the name of the update you want to install.
(Optional) Click CHECK to perform health checks.
For information about health checks, see Working with Health Checks.
Click APPLY to begin the update process.
Wait for controller A to fully reboot, and log back in to controller A.
Go to Configuration > Cluster and verify that controller A is in the "Ready (waiting for failback)" state.
For information about the cluster states, see Cluster Takeover and Failback in Oracle ZFS Storage Appliance Administration Guide, Release OS8.7.x.
(Optional) To monitor firmware updates, go to Maintenance > System and check the update counter.
Log in to controller B and go to Configuration > Cluster to verify that controller B is in the "Active (takeover completed)" state.
For information about the cluster states, see Cluster Takeover and Failback in Oracle ZFS Storage Appliance Administration Guide, Release OS8.7.x.
Go to Configuration > Cluster, and click FAILBACK to change the cluster to an Active/Active configuration.
Note - This is not necessary if you want an Active/Passive configuration.
Go to Maintenance > System, and click the arrow icon next to the name of the update you want to install.
(Optional) Click CHECK to perform health checks.
For information about health checks, see Working with Health Checks.
Click APPLY to begin the update process.
Wait for controller B to fully reboot, and then log back in to controller B.
Go to Configuration > Cluster to verify that controller B is in the "Ready (waiting for failback)" state.
For information about the cluster states, see Cluster Takeover and Failback in Oracle ZFS Storage Appliance Administration Guide, Release OS8.7.x.
(Optional) To monitor firmware updates, go to Maintenance > System and check the update counter.
Log in to controller A and go to Configuration > Cluster to verify that controller A is in the "Active (takeover completed)" state.
For information about the cluster states, see Cluster Takeover and Failback in Oracle ZFS Storage Appliance Administration Guide, Release OS8.7.x.
To verify that all firmware updates are complete, go to Maintenance > System and check the update counter.
Note - Do not begin the next step until all firmware updates are complete.
Go to Configuration > Cluster and click FAILBACK to change the cluster to an Active/Active configuration.
Note - This is not necessary if you want an Active/Passive configuration.

Both controllers are now upgraded.
Go to Maintenance > Hardware to verify that all disks are online.
All lights should be green.
Verify there are no controller and disk shelf component errors.
All lights should be green. An amber light indicates a component error.
If any components have errors, check for pool errors by going to Configuration > Storage, and check the STATUS and ERRORS columns for each pool.
Pools should be online and have no errors.
Log in to controller B and repeat steps 18-20 for controller B.
Enable any data services that were disabled before the upgrade, as described in Enabling a Service (BUI) in Oracle ZFS Storage Appliance Administration Guide, Release OS8.7.x.
