Use FAStT MSJ to determine what host adapters are present and where they are in the systems, as well as what RAID controllers are attached and whether they are on Fabric (switches) or loops. Figure 1 shows the FAStT MSJ window for a configuration with two 2340 host adapters.

adapters
As we expand the HBA tree we see what is attached to the HBA, as shown in Figure 2.
The HBA World Wide Name is 20-00-00-E0-8B-0F-E8-40 and it has one device attached to it. When the first two bytes of the Port ID display (and they are other than 00), the configuration is Fabric (switch). In the example below, the configuration is loop since the first two bytes are 0.
Note that the Port number (21-00-00-E0-8B-0F-E8-40) will be used to assign this HBA to the controller port to which it is attached. This will be done through ServeRAID Manager.

2340 host adapter
As shown in Figure 3, if you select one of the devices beneath the host adapter port, you find that it is a controller in a DS400 unit with one LUN assigned to it. FAStT MSJ refers to the controller as “Disk.” The controller is on-line and diagnostics have been enabled.
