Using SCF to Monitor a ServerNet Cluster

The Subsystem Control Facility (SCF) provides commands that display general

information about the ServerNet Cluster subsystem. SCF monitoring tasks include:

•

Displaying information and status for SNETMON and the ServerNet cluster

subsystem

•

Checking ServerNet cluster connections

•

Getting information for Expand-over-ServerNet processes, lines, and paths

Using SCF to Display Information About SNETMON

You can use the Kernel subsystem SCF INFO PROCESS command to display

configuration information for the ServerNet cluster monitor process. The recommended

generic process name is $ZZKRN.#ZZSCL. This process is also referred to as

SNETMON. Example 1-1 shows an SCF INFO PROCESS command and its output.

For more information about the SCF INFO PROCESS command, refer to the SCF

Reference Manual for the Kernel Subsystem.

You can also use the SCF LISTDEV command to display the SNETMON logical device

(LDEV) number, name, and device type. Example 1-2 shows an SCF LISTDEV

command and its output.

For more information about the SCF LISTDEV command, refer to the SCF Reference

Manual for G-Series RVUs.

Note. In this section, the ServerNet cluster monitor process ($ZZSCL) is referred to by its

abbreviation, SNETMON. And the symbolic name for the SNETMON generic process is

assumed to be ZZSCL, which is the recommended symbolic name.
