LSI Logic Adapter, and should be reserved for advanced users who fully
understand the implications of such changes.
The LSI Logic firmware supports several configuration options, defined
individually in Section 3.4.1, “Adjusting Link Speed,” and Section 3.4.2,
“Adjusting Interrupt Coalescing.” These options may be configured using
the MPTUtil utility menu, as described in the subsection entitled
“Running the MPTUtil Program”.
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 2
Gbit/s or 1 Gbit/s speed.
Note: The LSI7202XP-LC, LSI7202EP-LC, and LSI7202EP each
have two FC ports and the LSI7402XP-LC, LSI7402XP-LC,
and LSI7402XP-LC each have four FC ports, so the link
speed must be configured for each port. The
LSI7102XP-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 the DOS command line:
A:\ MPTutil
The MPTUtil program identifies all LSI Logic host adapters in
the system, and allows you to select which adapter to update
(Figure 3.4).
Step 2. The MPTUtil program displays a menu of options. (Figure 3.5).
To change the link speed on the LSI7202XP-LC Port 0 (lower
port, near the PCI connector), select the following menu option:
f-Toggle Board Speed on Function 0
To change the link speed on the LSI7202XP-LC Port 1 (upper
port from the PCI connector), select the following menu option:
