As your cluster requirements change, you might need to add, remove, or modify the device groups on your cluster. Oracle Solaris Cluster provides an interactive interface called clsetup that you can use to make these changes. The clsetup utility generates cluster commands. Generated commands are shown in the examples at the end of some procedures. The following table lists tasks for administering device groups and provides links to the appropriate procedures in this section.
Oracle Solaris Cluster software automatically creates a raw-disk device group for each disk and tape device in the cluster. However, cluster device groups remain in an offline state until you access the groups as global devices.
Caution - Do not run metaset -s setname -f -t on a cluster node that is booted outside the cluster if other nodes are active cluster members and at least one of them owns the disk set.
