After a very large I/O packet is lost in a Windows Server 2003 SAN environment, a long delay may occur before error recovery processing starts (916045)
The information in this article applies to:
- Microsoft Windows Server 2003, Datacenter Edition
- Microsoft Windows Server 2003, Enterprise Edition
SYMPTOMSA very large I/O packet may be lost or corrupted in a Microsoft Windows Server 2003 Storage Area Network (SAN) environment. In this case, it may take a long time for the I/O time-out to occur and for error recovery processing to start.
CAUSE
This problem occurs because the current Classpnp time-out algorithm increases the SCSI Request Block (SRB) time-out value by 60 seconds for every 64 KB of data transfer that is requested. The algorithm ignores the 60-second maximum time-out value in the registry.
STATUSMicrosoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
