Naming Connections
It is highly recommended that you assign names to connections that have meaning in
the context of your particular configuration. One system that works well is to name
each connection after its host, its adapter, its controller, and its controller host port, as
follows:
Examples:
A connection from the first adapter in the host named RED that goes to port 1 of
controller A would be called RED1A1.
A connection from the third adapter in host GREEN that goes to port 2 of controller B
would be called GREEN3B2.
NOTE: Connection names can have a maximum of 9 characters.
Numbers of Connections
The number of connections resulting from cabling one adapter into a switch or hub
depends on failover mode and how many links the configuration has:
• If a controller pair is in multiple-bus failover mode, each adapter has two
connections, as shown in Figure 1–7.
