Quick Reference: SCF Commands for Controlling a ServerNet
Cluster
Table 5-2 lists SCF commands that can be used to control components of a ServerNet
Cluster.
SCF Objects for Managing a ServerNet Cluster
Before using commands to control ServerNet cluster operations, be sure to review the
objects that represent components of the ServerNet cluster subsystem:
•
Kernel subsystem PROCESS objects for the following processes:
°
ServerNet cluster monitor process (SNETMON)
°
Message monitor process (MSGMON)
°
External ServerNet SAN manager process (SANMAN)
•
ServerNet Cluster subsystem (SCL) SUBSYS object
The Kernel Subsystem PROCESS Objects
The ServerNet cluster monitor processes are represented by Kernel subsystem
PROCESS objects. SCF commands for configuring, starting, stopping, and displaying
information about PROCESS objects are described in the SCF Reference Manual for
the Kernel Subsystem.
The SCL Subsystem SUBSYS Object
The SCL subsystem SUBSYS object represents the way in which the ServerNet
cluster monitor process starts ServerNet cluster services and joins systems to the
Table 5-2. SCF Commands for Controlling a ServerNet Cluster
