Read-only volume attribute clear after snapshot creation

Some VSS providers (I met such situation during the HP P4000 application aware snapshot creation) after snapshot creation leave read-only attributes bit set in created snapshots. In this situation the Snapshot or SmartVolume can be mounted to Windows server only as read-only volume.

To clear this attributes the Microsoft DiskPart utility can be used  (volume V: as example)

DISKPART> select volume V:

Volume 2 is selected volume.

DISKPART> attributes volume clear readonly

Volumes attributes cleared successfully.
