6.2. RSCT peer domain setup

A GPFS cluster requires an underlying RSCT peer domain. In this section, we describe the commands we used to create an RSCT peer domain on our experimental setup.

There are currently two types of domains in RSCT:

  • A management domain, with one management server and managed nodes. This is typically a CSM domain. The RSCT communication in this model flows between the management server and the nodes; it never flows between the nodes themselves.

  • A peer domain, where all nodes have the same role as far as RSCT is concerned. The information about the domain is available to all participating nodes through the use of Topology Services and Group Services, which are started upon creation of the peer domain.

Note that we do not ...
