partition by looking at the process table. However, you can run the following
commands to find out this information:
# lssrc -g hb
# lssrc -g hr
Following is an example of this output for the heartbeat:
Subsystem Group PID Status
hb.sppart2 hb 14302 active
hb.spcws hb 15332 active
and for the host_responds:
Subsystem Group PID Status
hr.sppart2 hr 16582 active
hr.spcws hr 16846 active
The partition name is appended to the daemon name to give a unique
subsystem name from which to determine which daemon is servicing which
partition.
With these distinct subsystems on the Control Workstation, each partition has its
own separate and distinct
heartbeat ring. These rings function completely
independently from each other with no heartbeat traffic flowing between the
rings.
Figure 69 shows this structure.

If there are any AIX Version 3.2.5 partitions, the heartbeat daemons on the
Control Workstation that service these will be started up in
compatibility mode
(but they are still hbd daemons) so that they can communicate with the ccst
daemons on the nodes.
