ScsiPort timeout errors

Karthigeyan_K · June 25, 2002, 3:55am

Hi,

I have a Windows 2000 + SP2 system with fibre channel HBAs
connected to a storage array.
When running I/O on the storage, I am seeing the following messages
in the event log:

The device, \Device\ScsiPort2, did not respond
within the timeout period.

It contains the following dump data:

0000: 0f 00 10 00 01 00 66 00 …f.
0008: 00 00 00 00 09 00 04 c0 …À
0010: 00 01 00 52 00 00 00 00 …R…
0018: 00 00 00 00 00 00 00 00 …
0020: 00 00 00 00 00 00 00 00 …
0028: 01 00 00 00 01 00 00 00 …
0030: 07 00 00 00 07 00 00 00 …

According to a Microsoft Support Article, Q182335,
http://support.microsoft.com/default.aspx?scid=kb;en-us;Q182335
there are two types of ScsiPort timeout errors:

(a) The I/O request does not complete within the allotted
time frame. Here, the UniqueErrorValue in the dump data
(offset 0x10) is set to 0x00000100.

(b) The SCSI adapter (HBA) did not respond to the system
after an I/O request has been issued. Here, the UniqueErrorValue
is set to 0x50000101.

* In the above dump data, UniqueErrorValue (0x52000100)
is neither of these two values. Is this a new type of ScsiPort timeout?
Any ideas under what conditions this error is logged?
Is this timeout documented anywhere?

Thanks in advance,
karthigeyan

Karthigeyan,

It is undocumented and it is a consequence of SRB_FUNCTION_RESET_BUS. It is
also not an error.

There are two timeout values you can play out with.

One is the disk timeout, create a TimeOutValue under HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Disk\ and set it to a min or two.
http://support.microsoft.com/default.aspx?scid=kb;en-us;Q248191
secondly if the HBA supports any timeout values, you can set that too (using registry or its management app)
