Re: Exchange Server Hangs OR REBOOTS



I would look at the Adaptec Storage manager if you are using it and inspect every disk that could have possibly generated a log entry about any Bad SCSI statuses. You should see a SCSI status similar to this output below:

Bad SCSI status - Check condition
28 00 02 D3 31 00 00 00 80 00 00 00

NOTE: If the first byte is the SCSI Status (0x28), then this indicates that the drive's Queue was full and it could not accept anymore I/O requests from the controller.

and

Request Sense
70 00 06 00 00 00 00 28 00 00 00 00 29 02 00 00 00 00
Unit Attention

NOTE: The 12th & 13th positions indicate the important response from the device - in this case 29 02 indicates "SCSI Bus Reset Occurred".

Do you have any drives that have orange or red lights on them as this would indicate a problem with that drive in your array? You might be able to look at this: http://www.moojit.net/Networking/downloads.shtml. I have never used this utility but you can give it a whirl.

Regarding the \Device\Scsi\dpti2o1 message, does the 1 at the end of dpti2o1
relate to hard drive 1 in my array?
