Yes here is th o/p of fdisk -l. Two Luns are assigned. one of 323 G and another of 359 G as seen blow. sda is my local disk. So do you think incorrect zoning can lead to this?
Thanks Paras.

Has any one seen this kind of situation? Sounds like zoning problem ..Storage is HDS and the LUN type created was of type netware. I don't know why this type but my storage administrator said its correct. This might be an issue?
Or if you can ellaborate how this is zoning problem it wud be great help.
Are you sure that you can see correct luns? check the size ?
