The LSI Logic firmware supports several configuration options, defined
individually in
Section 3.4.1, “Adjusting Link Speed,”
and
“Adjusting Interrupt Coalescing.”
These options may be configured using
the MPTUtil utility menu, as described in
3.4.1
Adjusting Link Speed
The link speed of the LSI Logic host adapters is configurable. By default,
the link speed is set to Auto. This means the host adapter automatically
detects the link speed of all other nodes on the link and automatically
adjusts itself to work with those nodes. If this automatic operation fails
(for example, other nodes on a loop do not support AutoNegotiation), the
LSI Logic host adapters may be configured specifically to either the
4 Gbit/s, 2 Gbit/s, or 1 Gbit/s speed.
Note:
The LSI7204XP-LC has two FC ports and the
LSI7404XP-LC has four FC ports, so the link speed must
be configured for each port. The LSI7104XP-LC has only
one port.
Configure the link speed of the host adapter by following these steps:
Step 1.
To set the link speed of the host adapter, execute this command
from DOS:
A:\ MPTutil
The MPTUtil program identifies all LSI Logic host adapters in
the system, and allows you to select which adapter to update
(
Step 2.
The MPTUtil program displays a menu of options. (
