Sun Cluster's scconf
Using scconf you can view some useful information about Sun Cluster configuration such as information about cluster transport, disksets, etc. Using multiple v’s you can increase output verbosity. It’s pretty useful especially if you inherited the cluster. I added this command to my Useful Sun Cluster commands, as well.
