of the optical cable.

Converter (GBIC) modules in the DSGGA, DSGGB, or DSGGC Fibre
Channel switch.
6.8.3.2 Setting the KGPSA-BC or KGPSA-CA to Run on a Fabric
The KGPSA host bus adapter defaults to the fabric mode, and can be used in
a fabric without taking any action. However, if you install a KGPSA that
has been used in the loop mode on another system, you will need to reformat
the KGPSA nonvolatile RAM (NVRAM) and configure it to run on a Fibre
Channel fabric configuration.
Use the wwidmgr utility to determine the mode of operation of the KGPSA
host bus adapter, and to set the mode if it needs changing (for example,
from loop to fabric).
______________________ Notes ______________________
You must set the console to diagnostic mode to use the wwidmgr
utility for the following AlphaServer systems: AS1200, AS4x00,
AS8x00, GS60, GS60E, and GS140. Set the console to diagnostic
mode as follows:
P00>>> set mode diag
Console is in diagnostic mode
P00>>>
The console remains in wwid manager mode (or diagnostic mode
for the AS1200, AS4x00, AS8x00, GS60, GS60E, and GS140
systems), and you cannot boot until the system is re-initialized.
Use the init command or a system reset to re-initialize the
system after you have completed using the wwid manager.
If you try to boot the system and receive the following error,
initialize the console to get out of WWID manager mode, then
reboot:
P00>>> boot
warning -- main memory zone is not free
P00>>> init
.
.
.
P00>>> boot
If you have initialized and booted the system, then shut down the
system and try to use the wwidmgr utility, you may be prevented
from doing so. If you receive the following error, initialize the
system and retry the wwidmgr command:
