Upgrading Clustered Controllers (BUI)
Before You Begin
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:
-
Click on the power icon in the upper left section of the
navigation bar.
-
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.
