can't see vmware connections in ns-120

hi all

i just wanted to ask a question, in which i am stucked since last 3 days,

i have vmaware esxi 5.1, having iscsi software adapter, which i wanted to connect with my NS-120,

i have already read and implement the solutions given on support pages, but all in vain,

it is also pertinent to mention that i am connecting the same vmware host with my AX4/5i, but in the case of NS-120, i am helpless,

please guide me for the procedure.

i will be really great full to all the advisers and experts.

thanks n regards
