| Description | The device, \Device\ScsiPort0, did not respond within the timeout period. |
| Event Information | According to Microsoft: CAUSE: EMCs Symmetrix disk array supports on line upgrade and reconfiguration operations that require stalling I/O operations at certain points during the operation. If these operations are carried out while the Symmetrix array is under load, the I/O stall may last longer than the default 10 second time-out value that Windows NT 4.0 sets for SCSI operations. This timeout value is 20 seconds for Windows 2000. RESOLUTION: WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk. To resolve this issue, add the TimeOutValue DWORD value in the following registry key. EMC recommends setting the value data to 60 seconds in decimal format. HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Disk\ This procedure is described in the Windows NT 4.0 DDK documentation release notes. EMCs Hardware Compatibility testing for HCL certification is done with TimeOutValue set to 60 seconds |
