Figure 3-9 Reliable Scalable Cluster Technology peer domain (RPD)

This implementation also makes use of Topology Services and Group Services.

This means that you have all nodes and all the RSCT components in use, as

shown in Figure 3-1 on page 52.

3.2.4 Combination of Reliable Scalable Cluster Technology domains

You can have a combination of all three types of domains (stand-alone,

management domain, and RPD) together with the old RSCT structure as used by

PSSP and HACMP/ES.

In this section, we focus on one implementation only: the combination of a RSCT

peer domain and a RSCT managed domain. An example of such a combination

might be using CSM with RPD-based GPFS on some nodes.

Node Y is a RSCT management server. You have three nodes as managed

nodes (Node A, Node B, and Node C). Node B and Node C are also using GPFS

on RPD. Therefore, you are required to configure a peer domain for these two

nodes, as shown in Figure 3-10 on page 61.
