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.

Steps

1. Perform the following actions to launch the Connect Disk wizard:
   1. In the left MMC pane, select the instance of SnapDrive you want to manage.
   2. Select Disks.
   3. From the menu choices at the top of MMC, navigate to Action > Connect Disk.

   The Connect Disk Wizard is displayed.

2. In the Connect Disk Wizard, click Next.
3. In the Provide a Storage System Name, LUN Path and Name panel, perform the following actions:
   1. Select a storage system from the drop-down menu, or type a new storage system name and click Enter.
   2. Double-click the volume that contains the Snapshot copy of the LUN you want to connect.
   3. Double-click the .snapshot directory and locate the appropriate Snapshot copy.
   4. Double-click the Snapshot copy and locate the LUN you want to connect.
   5. Click the LUN you want to connect and then clickNext.

   The Select a LUN Type panel is displayed.

   Note: If you cannot see the Snapshot copy directory, make sure that cifs.show_snapshot is set to on and vol options nosnapdir is set to off on your storage system.

4. 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.

   The Select LUN Properties panel is displayed.

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

   The Select Initiators panel is displayed.

6. In the Select Initiators panel, select the FCP or iSCSI initiator for the LUN you are connecting and click Next.

   The Select igroup Management Type panel is displayed.

7. In the Select Initiator Group Management panel, specify whether you will use automatic or manual igroup management. If you select automatic igroup management, SnapDrive uses existing igroups or, when necessary, creates new igroups for the initiators you specified in Step 6. If you select manual igroup management, you manually choose existing igroups or create new ones as needed.

   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 Step 6.
   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.

   You are done with igroup management.
