To upgrade a cluster from Solaris 8 to Solaris 9 software or from Solaris 9 to Solaris 10 10/05 software or compatible, with or without upgrading Sun Cluster software as well, you must instead perform a nonrolling upgrade. Go to Performing a Nonrolling Upgrade.
Ensure that all steps in How to Prepare a Cluster Node for a Rolling Upgrade are completed.
Perform this step to prevent the Solaris upgrade from attempting to mount the global devices.

Uncomment all entries in the /a/etc/vfstab file for globally mounted file systems that you commented out in Step 1.
Install any required Solaris software patches and hardware-related patches, and download any needed firmware that is contained in the hardware patches.
Do not reboot the node until Step 5.
Reboot the node into noncluster mode.
Include the double dashes (--) in the following command:
