Disk remain readonly inside guest while it is read-write enabled on hypervisor host

Hi,

Strangely Hyper-V guest is not updating its disk cache, even issuing diskpart rescan is not helping. So disk (Harddisk1) inside guestremains readonly while disk (Harddisk7) is read-write enabled on hypervisor host.

Hyper-V guest VM disk status

Thanks in Advance,

Hermesh
