DL380 G4 SCSI bus downshift Problem
---------------------------------------------------------------------------------
Problem:
---------------------------------------------------------------------------------
When I start this server it will execute a SCSI-bus Shiftdown within a day, resulting in a very slow disk responses (File copy of about 5-8MB/s which normally does about 20-30MB/s)
The Windows EvenViewer reports:
o Type: Error
o Source: disk
o Event: 11
o Description: The driver detected a controller error on \Device\Harddisk 3
These errors are ONLY reported for the 4x 300GB disken (2,3,4,5) and occure randomly for all 4 disks and NEVER for the 2x 72GB Boot disks (0,1)
The eventlog has reported about 1000 of these error messages over the past 9 months

HP Event Notifications:
---------------------------------------------------------------------------------
o SCSI bus fault occurred on Storage Box box 0, , Port 1 of Array Controller . This may result in a "downshift" in transfer rate for one or more hard drives on the bus.
The "HP System Management Homepage" reports: no failed/degrade items
The "HP Insight Diagnostics" does not report relevant errors
Full Event Logs are available
---------------------------------------------------------------------------------
Conclusion:
---------------------------------------------------------------------------------
The only thing I can think of is that the SCSI Backplane or the embedded SA6i controller is defective
It is not related to the 300GB disks as the errors where already there when they were added (they replaced 4x 146GB)
