Steps for Merging Three Star Topologies to Create a
Tr i-Star Top ology
You must log on to nodes attached to at least two different star groups of the tri-
star topology in order for the guided procedure to test all of the remote connections
on both fabrics.
11. Log on to a node attached to a different star group of the tri-star topology to test
the other remote connections. Run the Add Switch guided procedure again. In the
Local Switch Information dialog box, click the Test button to test the connectivity
between the local remote switches.
12. On all nodes in the newly merged cluster, use SCF to verify ServerNet
connectivity:
>SCF STATUS SUBNET $ZZSCL, PROBLEMS
13. Use the Configure ServerNet Node guided procedure to configure and start
Expand-over-ServerNet lines between the star groups of the tri-star topology.
Unless the automatic line-handler configuration feature is enabled, you must run
the Configure ServerNet Node guided procedure on every node in order to
configure and start the Expand lines to all other nodes.
From the system console of a node, choose Start>Programs>Compaq
TSM>Guided Configuration Tools>Configure ServerNet Node.
If you log on to a
node attached to . . .
The guided procedure checks
these remote connections . . .
X1/Y1 X1/Y1 to X2/Y2 and
X1/Y1 to X3/Y3
X2/Y2 X2/Y2 to X1/Y1 and
X2/Y2 to X3/Y3
X3/Y3 X3/Y3 to X1/Y1 and
X3/Y3 to X2/Y2
Note. In order to use the PROBLEMS option, T0294AAG (or a superseding SPR) must be
applied.
If the PROBLEMS option is not available, use the SCF STATUS SUBNET $ZZSCL
command on all nodes. SCF STATUS SUBNET $ZZSCL requires T0294AAA or a
superseding SPR. If remote passwords are configured, you can issue the SCF STATUS
SUBNET $ZZSCL command for a remote node (for example, \REMOTE) from the local
node as follows:
SCF STATUS SUBNET \REMOTE.$ZZSCL
This command eliminates the need to establish a logon window for each node.
