Assuming you mean Serviceguard, you use the cmviewcl command to determine which system a particular package is running on. There's not necessarily one primary node in a cluster since multiple packages can exist in a cluster and each one could run on a different node.

As Jeff already said, "cmviewcl" is the command you need.

In particular, use "cmviewcl -v" and then look at "Node_Switching_Parameters" in the section of each package.

The NODE_TYPE field will say either "Primary" or "Alternate".

These settings are specific to each package: for example, Node A may be the primary node for package X, while it is an alternate node for packages Y and Z.
