Static electricity can damage modules and electronic components.
We recommend using a grounded antistatic wrist strap and a
grounded work surface when handling modules.
1. Using the documentation that came with your Fibre Channel host bus
adapter, install the Fibre Channel adapter in an open 64-bit PCI slot.
2. Set the Fibre Channel adapter to run on fabric (see Section 4.2.2)
3. Obtain the Fibre Channel adapter worldwide node and worldwide port
names (see Section 4.2.3).
4.2.2 Setting the Fibre Channel Adapter to Run on a Fabric
The Fibre Channel host bus adapter (FCA) defaults to the fabric mode, and
can be used in a fabric without taking any action. However, if you install
an FCA that has been used in the loop mode on another system, you will
need to reformat the nonvolatile RAM (NVRAM) and configure it to run in a
Fibre Channel fabric configuration.
Use the worldwide ID manager (wwidmgr) console utility to determine the
mode of operation of the Fibre Channel host bus adapter, and to set the mode
if it needs changing (for example, from loop to fabric).
Use the wwidmgr utility to verify that the topology for all Fibre Channel host
bus adapters are set to fabric as shown in Example 4-1 and Example 4-2.
Example 4-1: Verifying Fibre Channel Host Bus Adapter Topology

pga0.0.0.3.1 - Nvram read failed
[ 0] pga0.0.0.2.0 1000-0000-c922-4aac FABRIC UNAVAIL

[9999] All of the above.
A Link is down message indicates that one of the adapters is not available,
which means that its probably not plugged into a switch.
The warning message Nvram read failed indicates that the Fibre
Channel host bus adapter nonvolatile random-access memory (NVRAM)
has not been initialized and formatted. The next topology will always be
UNAVAIL for the host bus adapter that has an unformatted NVRAM. Both
messages are benign and can be ignored for the fabric mode of operation.
