DRQ Timeouts. The number of times that a physical drive continued to request data, but did not get a command completion during the reference time (phyDrvRefTime). This value increases every time a DRQ timeout occurs for the physical drive. A defective drive or cable may cause DRQ timeouts to occur. If you see an increase in these errors, complete the following steps for the monitored system: 1. Check the cables connecting the drive to ensure that they are intact. 2. If the cables are properly connected, schedule server down time to run diagnostics to verify that a problem exists. If the value is not supported, it is set to 4,294,967,295.
