Information About What to Do Before Installing an Upgrade

Explain to the cluster administrator what he or she must do before installing the upgrade package on a node, as follows:

• If the upgrade package overwrites existing methods, instruct the cluster administrator to reboot the node in noncluster mode.

• If the upgrade package updates only the monitor code and leaves the method code unchanged, tell the cluster administrator to keep the node running in cluster mode. Also tell the cluster administrator to turn off monitoring of all resource types.

• If the upgrade package updates only the RTR file, leaving the method and monitor code unchanged, tell the cluster administrator to keep the node running in cluster mode. Also tell the cluster administrator to keep monitoring turned on for all resource types.
