Stopping ServerNet Cluster Services
Stopping ServerNet Cluster Services
You can use OSM or SCF to stop ServerNet cluster services.
Using OSM to Stop ServerNet Cluster Services
1. In the tree pane of the OSM Management window, right-click the ServerNet Cluster
resource, and select Actions.
2. From the Actions list, select Set ServerNet Cluster State and click Perform
Action.
3. In the drop-down list, select Stopped and click OK. The Action Status box shows
the progress of the action.
4. Click Close to close the Actions dialog box.
Verify that ServerNet cluster services are stopped. (See Using OSM to Check the
Status of the ServerNet Cluster Subsystem on page 1-14
Using SCF to Stop ServerNet Cluster Services
To stop ServerNet Cluster services on the local system, use the SCF STOP SUBSYS
$ZZSCL command:
> STOP SUBSYS $ZZSCL
When ServerNet Cluster Services Are Stopped
When you stop ServerNet cluster services, the ServerNet cluster monitor process
brings ServerNet cluster services to a STOPPED logical state. The ServerNet cluster
monitor process itself does not stop but remains an active process. Terminating access
to the ServerNet cluster proceeds:
1. The ServerNet cluster monitor process sets the ServerNet cluster subsystem state
to STOPPING and logs the state change.
2. The ServerNet cluster monitor process informs each remote ServerNet cluster
monitor process that the subsystem is stopping.
3. The ServerNet cluster monitor process instructs each local processor to terminate
ServerNet connectivity.
4. When the processors have finished terminating connectivity, the ServerNet cluster
monitor process moves the subsystem to the STOPPED state and logs the
Note. The STOP SUBSYS command stops ServerNet data traffic for a node on both external
fabrics (X and Y). By contrast, the SCF STOP SERVERNET $ZSNET command, when used
on a ServerNet node, stops internal and external ServerNet data traffic for only one fabric (X or
Y). No SCF command can stop ServerNet data traffic on only one external fabric.
