Problem MSA 30 DB + DL560 + SA6400

[mynto]

Hi,
We have a problem with MSA30DB connected to ProLiant DL560 G1 by SmartArray 6400. Approximately once a week some of the disks placed in MSA30DB disappear. After restart of server disks appear again but logical drive (RAID 1+0 based on 6 disks) which contains these disks has to be rebuilded. There is no rule on which drive or bus error occur. Below you can see errors from event viewer of Windows 2003:

Description:
SCSI bus fault occurred on Storage Box box 0, , Port 0 of Array Controller in slot 2.
This may result in a "downshift" in transfer rate for one or more hard drives on the bus.
-------------------------------------------
We have already upgraded firmware and driver of SmartArray 6400 and firmware of all disks.
SA6400:firmware Rev B, v2.62, Driver 5.70.0.32
Disks 146.8GB:Model COMPAQ BF14687B56, firmware HPB4

Could you give us any advice what we should do to solve the problem ?

Hi

I was wondering if you managed to get a fix for the above issue as we appear to be having the same issues.

This can be a problem with SCSI cable.

Please update to version 2.76A.

http://h18007.www1.hp.com/support/files/server/us/download/26776.html

Updated recommended hard drive firmware list with models that have been experiencing excessive SCSI command timeouts. When one of these drives is present, user will see a POST message recommending he upgrade the drive's firmware. Failure to upgrade may result in the bus down-shifting from Ultra 320 to Ultra 3.
