Controller/Driver error with Event ID 11

[BillClark22]

Running into an issue with BE11d and my server/bus adapter setup. The
backup "runs" but then fails on verification with an I/O error. Upon
further examination I see a System Event with the following: Source:
Lsi_scsi, Event ID: 11, Desription: "The driver detected a controller error
on \Device\RaidPort1". From what I gather there is something wrong with the
adapter/driver combination. The adapter is an HP SC11Xe Host Bus Adapter
(HP# 412911-B21) that I purchased separately from the DL380-G5 server it
resides in. The server came with the P400 Array that controls the internal
drives. Running Windows 2003 Server with Sp2 and all updates. I have all
the latest drivers and firmware for the LSI and the P400 and I still get
this error. Any ideas as to what is happening?? Need help ASAP!!
