Connecting to a LUN in a Snapshot copy

You can connect to a LUN in a Snapshot copy using either a FlexClone volume or a read/write connection to a LUN in a Snapshot copy depending on what version of Data ONTAP you have installed on your storage system.

Before you begin

Steps

1. 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.
2. Expand the LUN whose Snapshot copy you want to connect, then click on Snapshot Copies to display the list of Snapshot copies. Select the Snapshot copy you want to connect.
   Note: If you cannot see the Snapshot copy list, make sure that cifs.show_snapshot is set to on and vol options nosnapdir is set to off on your storage system.

3. From the menu choices at the top of MMC, navigate to Action > Connect Disk to launch the Connect Disk wizard.
4. In the Connect Disk Wizard, click Next.
5. In the Provide a Storage System Name, LUN Path and Name panel, the information for the LUN and Snapshot copy you selected is automatically filled in. Click Next.
6. In the Select a LUN Type panel, Dedicated is automatically selected because a Snapshot copy can be connected only as a dedicated LUN. Click Next.
7. In the Select LUN Properties panel, either select a drive letter from the list of available drive letters or type a volume mount point for the LUN you are connecting, then click Next.

   When you create a volume mount point, type the drive path that the mounted drive will use: for example, G:\mount_drive1\.

8. In the Select Initiators panel, select the FC or iSCSI initiator for the LUN you are connecting and click Next.
9. In the Select Initiator Group management panel, specify whether you will use automatic or manual igroup management.

   If you specify...	Then...
   Automatic igroup management	Click Next. SnapDrive uses existing igroups, one igroup per initiator, or, when necessary, creates new igroups for the initiators you specified in the Select Initiators panel.
   Manual igroup management	Click Next, and then perform the following actions: In the Select Initiator Groups panel, select from the list the igroups to which you want the new LUN to belong. Note: A LUN can be mapped to an initiator only once. OR Click Manage Igroups and for each new igroup you want to create, type a name in the Igroup Name text box, select initiators from the initiator list, click Create, and then click Finish to return to the Select Initiator Groups panel. Click Next.

10. In the Completing the Connect Disk Wizard panel, perform the following actions.
    1. Verify all the settings
    2. If you need to change any settings, click Back to go back to the previous Wizard panels.
    3. Click Finish.
