You can use the SnapDrive for Windows MMC snap-in to disconnect a dedicated or shared LUN, or a LUN in a Snapshot copy or in a FlexClone volume.
Before you begin
- Make sure that neither Windows Explorer nor any other Windows application is using or displaying any file on the LUN you intend to disconnect. If any files on the LUN are in use, you will not be able to disconnect the LUN except by forcing the disconnect.
- If you are disconnecting a disk that contains volume mount points, change, move, or delete the volume mount points on the disk first before disconnecting the disk containing the mount points; otherwise, you will not be able to disconnect the root disk. For example, disconnect G:\mount_disk1\, then disconnect G:\.
- Before you decide to force a disconnect of a SnapDrive LUN, be aware of the following consequences:
- Any cached data intended for the LUN at the time of forced disconnection is not committed to disk.
- Any mount points associated with the LUN are also removed.
- A pop-up message announcing that the disk has undergone "surprise removal" appears in the console session.
About this task
Under ordinary circumstances, you cannot disconnect a LUN that contains a file being used by an application such as Windows Explorer or the Windows operating system. However, you can force a disconnect to override this protection. When you force a disk to disconnect, it results in the disk being unexpectedly disconnected from the Windows host.
Steps
- Under SnapDrive in the left MMC pane, expand the instance of SnapDrive you want to manage, then expand Disks and select the disk you want to manage.
- From the menu choices at the top of MMC, navigate to either to disconnect normally, or to force a disconnect.
- When prompted, click Yes to proceed with the operation.
Note: This procedure will not delete the folder that was created at the time the volume mount point was added. After you remove a mount point, an empty folder will remain with the same name as the mount point you removed.
The icons representing the disconnected LUN disappear from both the left and right MMC panels.
