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, a Replace action for FCSAs 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 on page 3-2.
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.
When you replace an FCSA with a new adapter in the same slot without changing
anything on the path to the ESS, stop the DISK objects and install the new adapter.
The new adapter will have new WWNs. If the FCSA ports are directly connected to the
ESS fiber channel-ports, the WWNs still may need to be updated in the ESS. Normally,

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.
