3 Replacing an FCSA
This section describes how to replace a Fibre Channel ServerNet adapter (FCSA) in
an IOAM enclosure.
You might need to replace an FCSA if it has failed or partially failed. If POST fails and
an OSM alarm is generated on the FCSA SAC, you must replace the FCSA.
If you are moving the FCSA to a different slot, see Section 4, Relocating an FCSA.
Overview of FCSA Replacement Procedures
In the OSM Service Connection, there is a Replace action for FCSAs that performs
many of the SCF replacement tasks in the background. HP recommends that you use
the OSM Replace action and its associated help to replace the FCSA. If you decide to
use the OSM Replace action for all SCF tasks, you can omit Step 5 and Step 6
described in Prepare to Replace an FCSA.
Note that using the OSM Replace action alone has these effects:
•
Alarms are generated when you pull the adapter.
•
The I/O driver tries to recover when the paths are lost.
To prevent these effects, you can use SCF to switch paths and stop devices manually,
even though OSM can perform these tasks for you. If you choose to use SCF for
switching and stopping, follow the directions in Switch the Paths to Another FCSA and
Stop the Devices That are Using the Adapter on page 3-6 in Prepare to Replace an
FCSA.
When you replace an FCSA with a new adapter in the same slot without changing
anything on the path to the ESS, you stop the DISK objects and install the new
adapter.

Note. Whenever you handle an FCSA, follow standard operating practices to avoid damage to
the equipment. See Review Standard Operating Practices on page 2-8.
