Adjusting Default Firmware Settings
Occasionally, a user may find it necessary to adjust default firm-
ware parameters set by ADLINK during the original manufacturing
process. Adjustments to these parameters will affect future
behavior of the host adapters, and should be reserved for
advanced users who fully understand the implications of such
changes.
The firmware supports several configuration options, defined indi-
vidually in “Adjusting Link Speed” and “Adjusting Interrupt Coa-
lescing” below. These options may be configured using the
MPTUtil utility menu, as described in Command Line Update Tool
for DOS on page 19.
Adjusting Link Speed
The link speed of the host adapter is configurable. By default, the
link speed is set to Auto. This means the host adapter automati-
cally detects the link speed of all other nodes on the link and auto-
matically adjusts itself to work with those nodes. If this automatic
operation fails (for example, other nodes on a loop do not support
AutoNegotiation), the host adapter may be configured specifically
to either the 4 Gbit/s, 2 Gbit/s, or 1 Gbit/s speed..
Configure the link speed of the host adapter by following these
steps:
1. To set the link speed of the host adapter, execute this
command from DOS:
A:\ MPTutil
The MPTUtil program identifies all LSI host adapters in
the system, and allows you to select which adapter to
update (Figure 4-4: MPTUtil Device Selection on page 20).
NOTE: NOTE:
The link speed must be configured for each port.
