6780 Switch and Component Names

The layered topology is built with 6780 switches. A 6780 switch is represented in OSM

as a switch module. The full OSM switch name takes this form:

Switch Module $ZZSMN.Y23 (1021.3)

In this example:

•

Y21 indicates the fabric (Y), zone (2), and layer (3) of the switch.

•

(1021.3) contains the group and module number. The first two digits of all switch

group numbers is always 10. The next two digits of the group number represent

the zone (2) and fabric (where 0=X and 1=Y). The last digit (3) represents the

switch module number.

Note that the switch module number and layer number are equivalent.

For a listing of all possible switch names and identifiers, see Table 3-5 on page 3-29.

The components of the 6780 switch are named in the same manner, except that the

portion of the name in parentheses is extended to include a slot and possibly a port

number. For example, consider this name:

Switch Port $ZZSMN.Y21 (1021.1.6.2)

The part of the name in parentheses (1021.1.6.2) specifies group 1021, module 1,

slot 6, and port 2.

Learning More About Cluster Components

To become more familiar with the cluster components:

•

Read the following OSM subsections. They show you how to display information

about the different ServerNet cluster resources.

•

Select a cluster resource in the OSM Service Connection and press F1 to display

the online help. A description of the resource, including its attributes and any

available actions, appears.

Looking at a ServerNet Cluster From the

Remote Nodes

Because the view of a ServerNet Cluster can change significantly from one node to

another, you should gather data at each node by using both OSM and SCF. Then

compare the information:

•

With the OSM Service Connection, you can compare information by logging on to

the system console for each node in the cluster. Or, if an OSM dedicated LAN or a

public LAN is available that links multiple nodes, you can log on to any member

node from the same system console.
