attached storage problem!!!

Hi,

I have a shared storage which was working fine. Suddenly I have deleted my datacenter, cluster along with its virtual mechines. After recreating all these, I am not getting my storage which I have accessed before. It discoverd the luns, and allowing me to logged in. but not giving me chances to select my lun. (+) signs are dimed. I tried a lot. Please check the image I have uploaded. the last luns I am trying to get. other luns are not working as well.

Please help me.
