DiskRaid.exe does not populate "Array Lun number" correctly

Applies to: Windows Server 2008 R2 StandardWindows Server 2008 R2 EnterpriseWindows Server 2008 R2 Datacenter More

Symptoms


You have a Virtual Disk Service (VDS) 3.0 hardware provider installed that supports “LUN NUMBER SUPPORTED” feature on a computer (HOST) that is running Windows Server 2008 R2 or Windows 7.

When you run the Diskraid command to list the LUNs on the subsystem the right most column shows the array assigned LUN number. After selecting a HOST exposed LUN (NT Disk) and unmask it with /uninstall option. The disk will be uninstalled from the host system and then mask setting applied.

If you now execute the command “List luns” the selected LUN will now not show the array assigned LUN Number.

Cause


This is a bug as DiskRAID doesn’t show the output correctly.

Workaround


Exit and Restart DiskRAID to view detail LUN for the selected Lun, it does show the Lun number correctly.
