4.7.6 Set FC Link Speed

There are two modes of operation for FC: 1 Gbit/s and 2 Gbit/s. It is

important to match the speed of the port with the speed of the loop or

fabric to which the port is attached.

LSI Logic has implemented autonegotiation on the 2 Gbit/s-capable,

Fusion-MPT devices. If you are experiencing difﬁculty with the

AutoNegotiate algorithm on your fabric or loop, or if you wish to set or

show the link speed for the adapter manually, use the following

procedure:

Select the port or adapter shown (use the port name your system assigns):

ok select /pci@8,700000/IntraServer,fc@1

Then enter commands as shown in the following example:

ok show-link-speed

Link speed selected is 1 Gbaud

Current link speed is 1 Gbaud

ok set-link-speed

Note: The OpenBoot BIOS provides help when you enter a

command that does contain the proper arguments. In this

case, OpenBoot responds with:

usage is <link-speed> set-link-speed

ok a set-link-speed

Link speed selected is autobaud

Link speed has been set

Change will take effect after system power cycle
