Sun Cluster Data Services Developer's Guide for Solaris OS

Using the Boot Method

The RGM executes the Boot method on nodes or zones that join the cluster, that is, that have just been booted or rebooted.

The Boot method normally performs the same initialization as Init. You must code the Boot method so that it is idempotent. In other words, even if the Boot method has initialized the resource during a previous execution, subsequent calls to the Boot method exit successfully.
