4.5 Installing and Configuring the KGPSA PCI-to-Fibre
Channel Adapter Module
When you install the KGPSA PCI-to-Fibre Channel adapter module, you
have to ensure that it is configured symmetrically. The following sections
discuss KGPSA installation and configuration.
For an arbitrated loop configuration, you need to configure the link type of
the adapter for loop operation, as described in Section 4.5.3.
4.5.1 Obtaining the Worldwide Names of KGPSA Adapters
A worldwide name is a unique number that the Institute of Electrical
and Electronics Engineers (IEEE) assigns to a subsystem and that the
manufacturer sets prior to shipping. The worldwide name that is assigned
to a subsystem never changes. Obtain and record the worldwide names
of Fibre Channel components in case you need to verify their target ID
mappings in the operating system.
Fibre Channel devices have both a node name and a port name worldwide
name, both of which are 64-bit numbers. Most commands you use with Fibre
Channel only show the port name.
There are multiple ways to obtain the KGPSA port name worldwide name:
•
You can obtain the worldwide name from a label on the KGPSA module
before you install it.
•
You can use the
show dev
command as follows:
P00>>>
show dev
.

pga0.0.0.1.0
PGA0
WWN 1000-0000-c920-eda0
pgb0.0.0.2.0
PGB0
WWN 1000-0000-c920-da01
•
If the operating system is installed, the worldwide name of a KGPSA
adapter is also displayed in the boot messages generated when the
emx
driver attaches to the adapter when the adapter’s host system boots. Or,
you can use the
grep
utility and obtain the worldwide name from the
/var/adm/messages
file as follows:
#
grep wwn /var/adm/messages
F/W Rev 2.20X2(1.12): wwn 1000-0000-c920-eda0
F/W Rev 2.20X2(1.12): wwn 1000-0000-c920-eda0
F/W Rev 2.20X2(1.12): wwn 1000-0000-c920-eda0
.
.
.
Record the worldwide name of each KGPSA adapter for later use.
