Determine the Physical Location of the FCSA
If you are replacing an FCSA because it has failed, you probably have received an event message
telling you that one of a disk’s paths is not working. This might be the only way you know that
an adapter is down. To locate the adapter that has the problem, use the SCF INFO DISK DETAIL
command to determine the FCSA’s location. (See Figure 3-1.) Scan the command output for the
group, module, and slot location of the FCSA that is running the problematic path.
The sample command output is truncated to show only relevant information:
->INFO DISK $DS101, DETAIL
In this example, assume that $DS101 has a problem with its primary path. In the Primary Path
Information field, note the Location of the FCSA (group 11, module 2, slot 1).
NOTE: The display in Figure 3-1 (page 51) shows information about an adapter interfacing to
a NonStop S-series server. The group designation therefore has two digits. In Integrity NonStop
NS-series servers, the group designation consists of three rather than two digits. For more
information about the group designation in NonStop S-series and Integrity NonStop NS-series
systems, see Manufacturing Naming Conventions on page 1-11.

Identify the Devices
Now you need to find out all the devices that are using that adapter and check that they have
functioning alternative paths before you remove the adapter. Use the SCF STATUS ADAPTER
DETAIL command to display all the devices connected to the adapter:
->STATUS ADAPTER ZZSTO.#FCSA.GRP-11.MOD-2.SLOT-1, DETAIL
