5 Managing a ServerNet Cluster
This section describes how to monitor and control a ServerNet cluster. This section
contains two subsections:
Monitoring Tasks
Monitoring tasks allow you to check the general health of the ServerNet Cluster. These
tasks include:
•
Displaying Status Information Using the TSM Service Application on page 5-1
•
Running SCF Remotely on page 5-12
•
Displaying Information About the ServerNet Cluster Monitor Process (SNETMON)
on page 5-13
•
Checking the Status of SNETMON on page 5-14
•
Checking the Status of the ServerNet Cluster Subsystem on page 5-16
•
Checking ServerNet Cluster Connections on page 5-17
•
Checking the Version of the ServerNet Cluster Subsystem on page 5-17
•
Generating Statistics on page 5-18
•
Monitoring Expand-Over-ServerNet Line-Handler Processes on page 5-20
•
Monitoring Expand-Over-ServerNet Lines and Paths on page 5-20
Displaying Status Information Using the TSM Service
Application
You can use the TSM Service Application to gain information about the MSEBs, the
local node, the remote nodes, the external X and Y fabrics, and the ServerNet
Switches in the ServerNet Cluster. In the split-star and tri-star topologies, a cluster
switch appears as a remote switch in the TSM Service Application if you are logged on
to a server that is not directly connected to the switch.
The TSM Service Application obtains information about the local node and the fabrics
from both SANMAN and SNETMON. Information about the remote nodes is obtained
only from SNETMON.

Note. You can use OSM instead of TSM for any of the procedures described in this manual.
For information on using OSM instead of TSM, see Appendix H, Using OSM to Manage the
Star Topologies.
