Fibre Channel ServerNet Adapter Installation and Support Guide (G06.28+, H06.06+, J06.03+)

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.

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.
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” (page 50).
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” (page 55).
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, the ESS subsystem
recognizes the new FCSA WWNs, but if certain security parameters are set within the ESS, the
ESS subsystem does not use the new WWNs automatically. If the ESS subsystem does not
recognize the FCSA WWNs, when you restart the DISK object, the NonStop server returns Error
66. If you receive Error 66 after starting the paths for an FCSA connected directly to the ESS
fibre-channel ports, or if the FCSA ports are connected to the FC switch instead of directly to the
ESS fiber-channel ports, you must have the ESS or FC switch administrators enter the new FCSA
WWNs in the WWN zones in the SAN and in the appropriate host-group WWN configurations
in the ESS. Entering the new WWNs enables the SAN to recognize the new FCSA. When the new
WNNs are entered, restart the DISK object.
