There are various reasons which can cause hard drive not showing up in Disk Management and other hard drive related errors. We saw in device manager that there isn't an associated driver for the disk so the Windows team will have to find out why Windows system drivers aren't being assigned to the device.

Only if we were trying to mount the disk as a paravirtual controller would it be utilizing VMware drivers. Since the disk is loaded on a LSI SAS controller, the drivers for these devices are built into Windows. So the issue seems to be Windows related as we can see in the logs that the device is being mounted within the guest. We have opened SR with VMware and first approach from them to remove the vmdk file and added back but its didnt worked.Later on they asked us to re-boot the VM andĮven after re-boot its no luck,so finally they took ssh session and suggested that it is Windows Driver issues and windows team need to look.
