Hi All,

I created one LUN for my IBM host (vio) through NetApp, now when I am checking the LUN through LUN show command same LuN is shown multiple time with different hdisk value.

Any Suggestion!

Are there multiple network paths configured to this NetApp?  You'll need the MultiPath driver installed if not already.

It is configured. I am having this issue with only vio1 but vio2 is working fine and both are sharing the same Datastore.

Could use a little more info...  Have you tried deleting and recreating this LUN?  Can you read/write to this LUN equally well from both hosts?  If you create a second LUN and connect to both servers, is the same issue present?  Thx

I tried a lot time creating and deleting LUNs. I created two LUNs shared them between VIO1 and VIO2. VIO2 is showing LUN correctly but VIO1 is showing same LUN repeatedly.
