A2	sw1a and v1a*
B2	sw1b and v1b*
A3	v1a and sw2a*
B3	v1b and sw2b*

B4	AltMaster Sun StorEdge T3+ array and the “B” path switch
T1 to T2	sw2a and sw2b*

* Sun StorEdge 6900 series only

Note –In an actual Sun StorEdge 3900 or 6900 series configuration, there could be more Sun StorEdge T3+ arrays than are shown in FIGURE 2-1and FIGURE 2-2.

By using the Storage Automated Diagnostic Environment, you should be able to isolate the problem to one particular segment of the configuration.

The information found in this section is based on the assumption that the Storage Automated Diagnostic Environment is running on the data host, and that it is configured to monitor host errors. If the Storage Automated Diagnostic Environment is not installed on the data host, there will be areas of limited monitoring, diagnosis and isolation.

The following diagrams provide troubleshooting information for the basic components and Fibre Channel links specific to the Sun StorEdge 3900 series, shown in FIGURE 2-1, and the Sun StorEdge 6900 series, shown in FIGURE 2-2.
