Troubleshooting SANMAN

For general information about SANMAN, refer to Section 1, ServerNet Cluster

Description. $ZZKRN.#ZZSMN is a persistent process that should be configured to be

started at all times. SANMAN must be in the STARTED state on a system in order for

the system to join a ServerNet cluster.

Use the following steps to troubleshoot SANMAN:

1. Verify that SANMAN is started. Do one of the following:

•

Using the TSM Service Application, click the ServerNet Cluster resource to

select it, and check the SANMAN Process State attribute. See Figure 7-6 on

page 7-18.

•

At an SCF prompt type:

-> STATUS PROCESS $ZZKRN.#ZZSMN

2. If $ZZKRN.#ZZSMN is not configured, refer to Section 3, Installing and Configuring

a ServerNet Cluster, for information about configuring it.

3. If $ZZKRN.#ZZSMN is configured but not started, use SCF to start it:

-> START PROCESS $ZZKRN.#ZZSMN

4. If you continue to have problems, contact your service provider.

Note. If $ZZKRN.#ZZSMN does not appear to be available, it might be configured

using a different symbolic name. Use the SCF INFO PROCESS $ZZKRN.* command to

display a list of all currently configured generic processes.

Note. Systems using the Tetra 8 topology must have a version of SP firmware that supports

clustering to participate in a ServerNet Cluster. Otherwise the ServerNet cluster processes

$ZZKRN.#ZZSCL (SNETMON) and $ZZKRN.#ZZSMN (SANMAN) will abend repeatedly when

a system load is performed with G06.09 or later. Installing a version of the SP firmware that

supports clustering after the cold load and subsequently trying to start $ZZSCL and $ZZSMN

does not correct the problem.

To correct the problem, you must install a version of SP firmware that supports clustering and

then perform a system load. To determine which version of SP firmware you need, see

Checking SPR Levels

on page 2-24.

This problem does not affect systems that use the Tetra16 topology.
