Starting ServerNet Cluster Services
any of the SNETMON process configuration attributes if you configured SNETMON
with the TACL macro documented in the ServerNet Cluster 6780 Planning and
Installation Guide.
Aborting SNETMON on a node does not change the state of ServerNet Cluster IPC
connectivity to and from that node. However, while SNETMON is not running, the node
cannot:
•
Bring up remote IPC connectivity to any processor that is reloaded in the cluster
•
Bring up IPC connectivity to any new node that is added to the cluster
•
Automatically repair any failed remote IPC connections.
Expand-over-ServerNet lines to any new node that is added to the cluster while
SNETMON is not running cannot be brought up either.
Although ServerNet Cluster IPC connectivity is not brought down when the SNETMON
process is aborted, Expand-over-ServerNet lines tolerate only temporary absences of
SNETMON. Typically, Expand-over-ServerNet lines for the node are brought down if
SNETMON is aborted and is not restarted within five minutes.
Starting ServerNet Cluster Services
You can use OSM or SCF to start ServerNet cluster services.
Using OSM to Start 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 Available Actions list, select Set ServerNet Cluster State and click
Perform Action.
3. In the ServerNet Cluster State drop-down list, select Started and click OK. The
Action Status box shows the progress of the action.
4. Click Close to close the Actions dialog box.
5. Verify that ServerNet cluster services are started. (See Using OSM to Check the
Status of the ServerNet Cluster Subsystem on page 1-14.)
Using SCF to Start ServerNet Cluster Services
To start ServerNet cluster services on the local system, use the SCF START SUBSYS
$ZZSCL command:
> START SUBSYS $ZZSCL
Note. If you try to start ServerNet cluster services before the fiber-optic cables are connected
between the MSEBs in group 01 and the cluster switches, you receive an error.
