Controlling ServerNet Cluster
Processes
This section describes how to perform tasks that control the state of the ServerNet
cluster processes.
The Subsystem Control Facility (SCF) is the primary tool for performing these tasks.
For detailed syntax and descriptions of the SCF commands used in this section, see
Section 4, SCF Commands for SNETMON and the ServerNet Cluster Subsystem, and
Section 5, SCF Commands for the External ServerNet SAN Manager Subsystem.
The tasks for controlling the processes in a ServerNet cluster include:
•
Starting the Message Monitor Process (MSGMON) on page 2-3
•
Aborting the Message Monitor Process (MSGMON) on page 2-3
•
Starting the External ServerNet SAN Manager Process (SANMAN) on page 2-4
•
Aborting the External ServerNet SAN Manager Process (SANMAN) on page 2-4
•
Restarting the External ServerNet SAN Manager Process (SANMAN) on page 2-5
•
Starting the ServerNet Cluster Monitor Process (SNETMON) on page 2-5
•
Starting ServerNet Cluster Services on page 2-6
•
Stopping ServerNet Cluster Services on page 2-8
•
Switching SNETMON or SANMAN Primary and Backup Processes on page 2-9
Some of these tasks can also be performed with the OSM Service Connection. These
tasks include stopping and starting ServerNet Cluster Services and switching the
primary processor for SNETMON and SANMAN. The OSM method for performing
each of these tasks appears along with the corresponding SCF example.
