clvt API

These topics describe the clvt (cluster virtualization tool) API.

The clvt commands perform PowerHA® SystemMirror® cluster operations. Cluster operations include adding, deleting, and querying cluster objects, as well as bringing nodes on or offline and modifying resource groups and interfaces.

The general syntax for clvt commands:

clvt action class object name [name=value]...

Not all action class combinations require object or name=value pairs.

Not all commands have output. If they do, this is noted.

If the user enters an illegal value, the return code is non-zero. Not all commands produce error messages.
