5.5.6. Adding or Deleting a GULM Lock Server Member

The procedure for adding or deleting a GULM cluster member depends on the type of GULM node:
either a node that functions only as a GULM client (a cluster member capable of running applications,
but not eligible to function as a GULM lock server) or a node that functions as a GULM lock server.
The procedure in this section describes how to add or delete a member that functions as a GULM lock
server. To add a member that functions only as a GULM client, refer to
Client-only Member"; to delete a member that functions only as a GULM client, refer to
