Scsi problems with MPT-Fusion-based HBA

[paw]

Hi,

I am hoping that the experts on the list may be able to give me some 
insight with an a scsi-related problem I am experiencing. I am simply 
looking for an interpretation of what this I/O means, or what I might be 
able to try to solve the problem.  The equipment is in a remote 
location, and spare parts are not available to try swapping things out.  
Thanks in advance for all your help,  --paw


Kernel:  2.4
Server:   HP Proliant 380DL
Scsi:   (HP Part # 268351-B21, LSI Logic / Symbios Logic 53c1030 PCI-X 
Fusion-MPT Dual Ultra320
Device:  Western Scientific EonStor A16F/A16U Disk Array  16-disk, 6TB 
RAID divvied into 2TB partitions
Connection: Single 3 foot scsi cable rated to U320.

Problems:
Extremly poor throughput, and intermittant,  debilitating Scsi errors 
causing lockups. Server reboots necessary to clear error conditions
