I totally agree with MadeInGermany that you should check for a firmware/driver update.
Also, if you have a working configuration then that's always a good start since you can compare setting with the faulty system.
It does rather look like the primary suspects are the FC adapter(s) so I would compare all the QLogic BIOS settings against the working configuration and justify in your own mind the reason for any differences.
In particular I would be checking (with typical values I would expect to see in brackets) Frame Size (2048) and Execution Throttle (64).
You might also consider talking to QLogic tech support.

Hi,
I'm trying to determine which HBA cards are installed on my Solaris 10 (Sun-Fire-V240) machine.
The relevant data I have is below, but from it I cannot ascertain for sure if I have Emulex 10000 or 11000 HBA cards.
Can anyone suggest how to determine my HBA hardware ?
Thanks,
Ron.

NAME
qlc - ISP2200, ISP2300, and SP212 Family Fibre Channel host bus adapter driver.
SYNOPSIS
SUNW,qlc
The qlc host bus adapter driver is a Sun Fibre Channel transport layer-compliant nexus driver for the Qlogic ISP2200, ISP2200A, ISP2310,
ISP2312, and SP212 adapters. These adapters support Fibre Channel SCSI and IP Protocols, FC-AL public loop profile, point-to-point fab-
ric connection and Fibre Channel service classes two and three (see NOTES section below).
The qlc driver interfaces with the Sun Fibre Channel transport layer to support the standard functions provided by the SCSA interface. It
supports auto request sense and tagged queueing by default. The driver requires that all devices have unique hard addresses in private
loop configurations. Devices with conflicting hard addresses are not accessible.

NOTES
SP-212-based host bus adapters (including QLA-210) are supported on x86 platforms only and are limited to a maximum of 8 targets in fab-
ric and sixteen targets in local loop topology. FL topology is not supported with the SP-212-based host bus adapter.
