It sounds like you've done all the logical troubleshooting on the PSL NIC. Replacement seems the next most likely course.
On the SRCSASRB, what part of it is showing 128MB?
Bad, bad, how long is Warranty for the PSL Boards? How to become replacement?
SRCSASRB - shows me at the Boot Screen (the other controllers shows 256MB ), also in the Raid Manager this one shows only 128 mb, the other ones show me 256 mb
It's a three-year warranty on the PSL board. You can replace it through Intel I think, but it's usually way faster to go through whomever you bought it from.
No idea on the SRCSASRB.
I realize this thread is a bit old, but I have the same issue with my SRCSASRB. It shows as only having 128MB. Did you ever find a solution to your issue?
