We have no SCSI device in the server, but we use the ISCSI to network to other company's Hard disk!
is that the problem?

Not sure...are there any other associated messages in the event viewer?

Also, do a regedit and search for aa81xx and see if there is more information that can provide detail on that particular entry.

This error is common to a lot of SCSI controllers.
Check the article below for troubleshooting tips/hints:

Are you using the latest iSCSI initiator? Current version is 2.03 (11/29/2006)
Are you using teaming software for your network connections? There are known issues with teaming and iSCSI.

From Microsoft:

The device \device\SCSI\%scsiport% did not respond within the time period
event code 9

The two types of timeouts are distinguished by the presence (or absence) of the ASCII character "P" in offset 0x13 of the byte data.

The first type of timeout is one in which the I/O did not complete in the allotted time frame. Within the SRB for each I/O is a TimeOutValue, in seconds, which is longer for larger data transfers and shorter for smaller data transfers. This type of timeout is indicated by a UniqueErrorValue equal to 0x00000100 in the event log. This timeout indicates that an I/O did not complete in the allotted time.

You'll get this message on an iSCSI card when the machine cannot access the SAN for a short period .. If you have a SAN node w/multiple clusters this error would be generated if there is a configuration issue w/the SAN. but more than likely its just an error generated when the system temporarily loses connection with the SAN. This will be more common in high traffic environments and over WAN links.

What type of iSCSI card do you have?
