Only nodes in the home cluster will participate as token managers.

Note that "mmdiag --tokenmgr" lists all potential token manager nodes, but
there will be additional information for the nodes that are currently
appointed.

--tokenmgr
   Displays information about token management. For each mounted GPFS file
   system, one or more
   token manager nodes is appointed. The first token manager is always
   colocated with the file system
   manager, while other token managers can be appointed from the pool of
   nodes with the manager
   designation. The information that is shown here includes the list of
   currently appointed token
   manager nodes and, if the current node is serving as a token manager,
   some statistics about prior
   token transactions.
