Upgrading a ServerNet Cluster

Steps for Merging Three Star Topologies to Create a

Tr i-Star Top ology

4. If you have not already done so, upgrade all nodes in all clusters to G06.13 or a

later G-series RVU. For nodes upgraded to G06.13, you must apply the release 3

SPRs indicated in Table 4-6 on page 4-8. Refer to Upgrading Software to Obtain

G06.14 Functionality on page 4-34.

5. On any node connected to one of the clusters, run the Add Switch guided

procedure:

a. From the system console of that node, choose Start>Programs>Compaq

TSM>Guided Configuration Tools>Add Switch.

b. In the Select Upgrade Topology dialog box, select the tri-star topology as the

topology to which you want to upgrade.

c. In the Select Switch Configuration Tag dialog box, select one of the following

configuration tags:

•

Max 24 nodes, nodes 1-8 (0x10002)

•

Max 24 nodes, nodes 9-16 (0x10003)

•

Max 24 nodes, nodes 17-24 (0x10004)

d. Follow the dialog boxes to update the firmware and configuration for the X-

fabric cluster switch if the guided procedure determines that the switch needs

updating.

e. When prompted, update the firmware and configuration for the Y-fabric cluster

switch. The guided procedure remembers the configuration tag you selected

for the X-fabric cluster switch and uses it for the Y-fabric cluster switch.

f. When the guided procedure prompts you to connect the cables for the X fabric,

click Stop Task. You must not connect the two-lane link cables until all the

cluster switches have been updated.

6. Repeat Step 5 on the second cluster.

7. Repeat Step 5 on the third cluster, but do not click Stop Task when the guided

procedure tells you to connect the cables.

8. Connect the two-lane links on both fabrics using the fiber-optic cables. See

Connecting the Two-Lane Links on page 4-87.

9. When the cables are connected, click Continue in the Connect the Cables dialog

box.

10. In the Local Switch Information dialog box, click Test to verify the connection

between the cluster switches.
