Task 2: Route the Fiber-Optic Cables for the Two-
Lane Links
Task 2: Route the Fiber-Optic Cables for the Two-Lane Links
The following tasks assume that you have routed (but not connected) the single-mode
fiber-optic cables to be used for the two-lane links. (Do not connect the two-lane links
until you are instructed to do so by the guided procedure.) If you have not already
routed the cables:
1. Label both ends of each fiber-optic cable to be used for the two-lane links. On the
label, include the fabric and cluster switch position (X1, for example) and the port
number (8, for example) to which the cable will be connected.
2. Route the cables. For more information, refer to Section 2, Planning for Installation.
Task 3: Install the Three Star Groups of the Tri-Star Topology
Use the procedure for Installing a ServerNet Cluster Using a Star Topology on
page 3-1 to install three ServerNet clusters, each containing one cluster switch per
fabric and up to eight nodes.
You can save time by configuring the clusters to use the X1/Y1, X2/Y2, and X3/Y3
cluster switches, but this practice is not required. The Add Switch guided procedure
detects the cluster switch configuration and gives you an opportunity to change it
before merging the clusters.
Task 4: Use the Guided Procedure to Prepare to Merge the
Clusters
Before merging the three star groups of the tri-star topology, you must use the Add
Switch guided procedure to verify that the hardware and software are ready.
1. On any node connected to one of the star groups, run the Add Switch guided
procedure:
a. From the system console of that node, for TSM, choose
Start>Programs>Compaq TSM>Guided Configuration Tools>Add Switch. For
OSM, the guided procedure is launched from within the OSM Service
Connection by performing the Replace action from the Switch object.
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)
