Fibre Channel Links
The following sections provide troubleshooting information for the basic
components and Fibre Channel links, listed in
TABLE 2-1.
Note – In an actual Sun StorEdge 3900 or 6900 series configuration, there could be
more Sun StorEdge T3+ arrays than are shown in FIGURE 2-1 and 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.
