## Uninstalling a Package

You can remove a single package or multiple packages.

## How to Uninstall a Package

1. Assume a role that provides `solaris.cluster.admin` RBAC authorization.
2. Uninstall an existing package.

       # pkg uninstall pkg-fmri

   If you want to uninstall more than one package, use the following syntax.

       # pkg uninstall pkg-fmri pkg-fmri

   The `pkg uninstall` command will fail if there are other installed packages that depend on the pkg-fmri you are uninstalling. To uninstall the pkg-fmri, you must supply the `pkg uninstall` command with all the pkg-fmri dependents. For additional information on uninstalling packages, see Adding and Updating Oracle Solaris 11.1 Software Packages and the `pkg`(1) man page.

## How to Uninstall Quorum Server or AI Installation Server Packages

1. Assume a role that provides `solaris.cluster.admin` RBAC authorization.
2. Uninstall the quorum server or AI installation server packages.

       # pkg uninstall ha-cluster/*

   | Caution - This command uninstalls all `ha-cluster` packages installed on the system.

### Updating Tips

Use the following tips to administer Oracle Solaris Cluster updates more efficiently:

- Read the SRU's `README` file before performing the update.

- Check the update requirements of your storage devices.

- Apply all updates before running the cluster in a production environment.

- Check the hardware firmware levels and install any required firmware updates that might be needed. Consult your hardware documentation for information on firmware updates.

- All nodes acting as cluster members must have the same updates.

- Keep cluster subsystem updates up to date. These updates include, for example, volume management, storage device firmware, and cluster transport.

- Test failover after major updates. Be prepared to back out the update if cluster operation is degraded or impaired.

- If you are upgrading to a new Oracle Solaris Cluster version, follow the instructions in the Oracle Solaris Cluster Upgrade Guide.
