Could you load the driver with the ql2xextended_error_logging module
parameter enabled:

	$ echo "6 4 1 7"  > /proc/sys/kernel/printk
	$ insmod qla2xxx.ko ql2xextended_error_logging=1

and forward over the resultant messages file beginning with the load
of the driver to the point at which the File-system failure occurs.

I can setup somthing similar locally, I take it you are writing
directly some some lun exported off the DS400, and not using DM?

Just curious, what are those errors?

Please also provide the output of:

	$ cat /proc/scsi/scsi
	$ lspci -vvx

and your .config file.
