PD hints - Disk disappearance


Disk disappearance

In Microsoft Windows 2003 and Windows 2000 operating systems, volumes on new disks are not automatically mounted and assigned drive letters by default when added to the system at boot-up. As a result, when a disk is no longer accessible due to a malfunction (for example, a bad cable), the Windows operating system will treat this as a Removable Disk event. Figure 1 shows the event posted when Windows no longer detects a disk. This can be caused by a failure in the Enclosure unit or a mis-configuration of the storage. Using the ServeRAID Manager, ensure that the device (logical drive) is still available to this initiator.

Several things can cause a drive to disappear, including a failed path to the storage unit (for example, the DS400). Return to Disk Disappearance to continue with PD Maps (click the Back button on your browser).
