Consider the following when powering on and powering off cluster hardware:
Use the power-on and power-off procedures in the manuals that shipped with the hardware only for systems that are newly installed or in the process of being installed.
Use power-on and power-off procedures in Sun Cluster 3.0 System Administration Guide for nodes in an existing cluster.
After the cluster is online and a user application is accessing data on the cluster, do not use the power-on and power-off procedures listed in the manuals that came with the hardware.
