Decoding mptscsih errors

[Patrick_Boyd at Dell.com]

No ID 6 is the backplane. By default all Dell backplanes or enclosures
use target 6 unless the enclosure is in cluster mode and then it will
use target 15. 

Can you tell us what the system is doing when the lockup occurs?

Hi,


Errors (posted at the bottom) seem to only occur during boot. Node is
experiencing intermittent lockups...so i am trying to follow every lead.
Motherboard has been replaced 2 days ago by Dell....lockups after a day
or so still occuring. Dell diagnostics (from EW5076A0) and MPMemory come
out clean.

Here are all the devices.
scsi2 is the where the root device is...where id 0, lun 0 is the root
disk, and id 6, lun 0 is the controller? 
The failure is in the controller(?),id 6! Trying to understand it.....

# cat /proc/scsi
