SunCluster Quick Command Reference

Hey There,

Well, sitting back and reflecting today, I realized that we've done our fair share of posts on cheat-sheets and such (Our LVM command reference, for example). However, when it comes to clustering systems, we've probably been unfair in our bias toward Veritas Clustering as opposed to SunCluster, for which we've only put up, I believe, one post with our Simple SunCluster Monitoring Script (Thankfully linked back to from The SunCluster Wiki). What's a poor blog to do? ;)

With that in mind, today we're going to lay down a quick command reference for SunCluster. Hopefully you'll find it useful and enjoy it :) Of course, it assumes that you know, mostly, how to use SunCluster (and are familiar with basic clustering concepts), but it can be used as an attractive wallpaper, if nothing else ;)

All of this information, and much more, can be found at Sun's Online Documentation Center for SunCluster.

Enjoy,

SHUTTING DOWN AND BOOTING A CLUSTER

To shut Down the Entire Cluster:

host # cluster shutdown

From one node:

host # clnode evacuate
host # shutdown - Shut Down a Single Node

To boot a Single Node from the OBP:

ok> boot

To reboot a Node Into Noncluster Mode from the OBP:

ok> boot -x
