Updating or Patching a Zone Cluster

Language:

To update a solaris branded zone cluster, you apply an SRU by using the scinstall-u update command.

To patch a solaris10 branded zone cluster, apply a patch by using the clzonecluster install-cluster -p command or the patchadd command, or by patching an alternate boot environment.

This section provides the following procedures:

How to Update a `solaris` Branded Zone Cluster

Perform this procedure to update a solaris branded zone cluster by using the scinstall-u update command to apply an SRU.

Assume a role that provides solaris.cluster.admin authorization on a node of the global cluster.
From a node of the global cluster, update the entire node.
```
phys-schost# scinstall -u update [-b be-name]
```
Repeat this step on each cluster node.
Reboot the cluster.
```
phys-schost# clzonecluster reboot
```

How to Patch a `solaris10` Branded Zone Cluster (clzonecluster)

Perform this procedure from one node of the global cluster.

Assume a role that provides solaris.cluster.admin authorization on a node of the global cluster.
Boot the zone cluster into Offline Running mode.
- If the zone cluster is not booted, run the following command.
```
phys-schost# clzonecluster boot -o zone-cluster
```
- If the zone cluster is booted, run the following command.
```
phys-schost# clzonecluster reboot -o zone-cluster
```
From one node of the global cluster, patch the entire solaris10 branded zone cluster.
```
phys-schost# clzonecluster install-cluster -p patch-spec [options] zone-cluster
```
For more information about the install-cluster subcommand, see the clzonecluster(1CL) man page.

Note - If the scinstall -u update command fails with a message that the pkg command is out of date, follow the instructions in the message.

Reboot the zone cluster.

phys-schost# clzonecluster reboot zone-cluster

How to Patch a `solaris10` Branded Zone in a Zone Cluster (`patchadd`)

Perform the following steps on each configured zone-cluster node.

Bring the zone cluster into an offline-running state.
```
phys-schost# clzonecluster reboot -o zone-cluster
```
Log in to the zone-cluster node.
```
phys-schost# zlogin zone-cluster
```
From the command line, type patchadd.
```
zchost# patchadd
```
Install the patches that correspond to the new release.

How to Patch an Alternate Boot Environment for a Zone in a `solaris10` Branded Zone Cluster

Use this procedure to patch an alternate boot environment (BE) for the zone of zone-cluster node. This method provides the option of backing out of the patched BE if necessary.

Become administrator for the zone of the zone-cluster node you want to patch.
Create, patch, and activate a new boot environment, then use the shutdown command to reboot the zone.
Follow instructions for these tasks that are contained in How to Create and Activate Multiple Boot Environments on a solaris10 Branded Zone in Creating and Using Oracle Solaris 10 Zones.
Repeat the preceding steps for the zones of any other zone-cluster nodes that you need to patch.
