    Try to increase the size of the containing volume (if there is any free space left in the aggregate) & then try to online the LUN.

    The LUN has gone offline due to the containing volume filling up.  If this LUN was built to best practices then there will only be this single LUN inside the volume, which means that the only thing that can fill the volume up are either snapshots (or a combination of overwrites which blow out the snapshots).  As Radek says, you can resize the volume if there is room in the containing aggregate or if there is no room you can identify snapshots which the customer is willing to delete and then (only if they agree) delete them to free up space.  You can then bring the LUN online.

    This LUN, which I see is the SnapInfo LUN does not usually fill up so I would check a few things.  Ensure scheduled snapshots are disabled for all LUN volumes on the controller.  Only SnapManager should be scheduling Snapshots.


    Also, reading the following article, which is very useful:
