Shutdown gracefully Red hat cluster with UPS

Hi,
I'm planning to secure my Linux cluster système (2HP DL380 G5 server and one MSA 1000 storage)with a UPS.I would like the UPS to shutdown gracefully the cluster if any electricity issue (light off).
I've heard that it's possible with server, but my système is a cluster.
Can somebody can help?

Probably, the UPS provider will give you an application to run a command/script.

In your script, use ssh to shutdown the other nodes, then shutdown the server itself.

Thanks Ivan,
but what about the storage?
I'm used to shutdown the storage physically, and also, the system is a cluster, normal steps to shutdown a cluster is to shutdown the servers first and than the storage.

Yes, that is true, but as far I know, the MSA does not have a shutdown/poweroff command on the CLI.
