Task 6: Configure Expand-Over-ServerNet Lines for
the Remote Nodes
Task 6: Configure Expand-Over-ServerNet Lines for the Remote
Nodes
Unless automatic line-handler configuration is enabled, the ServerNet nodes in each
half of the split-star topology will not have Expand-over-ServerNet line-handler
processes configured for the remote nodes in the other half of the split-star.
You can use a guided configuration procedure to configure and start Expand-over-
ServerNet lines between the two halves of the split-star topology. You must perform
this procedure on all nodes in the cluster.
From the system console of the system you are adding, for TSM choose
Start>Programs>Compaq TSM>Guided Configuration Tools>Configure ServerNet
Node. For OSM, the guided procedure is launched from within the OSM Service
Connection by performing the Add Node to ServerNet Cluster action from the
System object. Online help is available to assist you in performing the procedure.
Task 7: Verify Operation of the Cluster Switches
1. Log on to a node in the range of ServerNet node numbers 1 through 8, and use the
OSM Service Connection or TSM Service Application to verify the operation of the
local X-fabric and Y-fabric cluster switches.
2. Log on to a node in the range of ServerNet node numbers 9 through 16, and use
the OSM Service Connection or TSM Service Application to verify the operation of
the local X-fabric and Y-fabric cluster switches.
Task 8: Verify Cluster Connectivity
On all nodes in the newly merged cluster, use the SCF STATUS SUBNET $ZZSCL
command to verify ServerNet cluster connectivity.
Note. Using the SCF STATUS SUBNET $ZZSCL command requires T0294AAA or a
superseding SPR. If remote passwords are configured, you can issue the SCF STATUS
SUBNET $ZZSCL command for a remote node (for example, \REMOTE) on the local node as
follows:
SCF STATUS SUBNET \REMOTE.$ZZSCL
This command eliminates the need to establish a logon window on each node.
