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 .
