Are you planning to install EMC VSI plugin to provision storage through vsphere client?
If its generallly making storage available, you will have to create LUNs on VNX and assign them to ESXi servers.
Then format them with VMFS and create datastores. Once this is done, you will be able to add storage to the VM's using that datastore.

You create a new virtual disk, and specify the new virtual disks to be stored on the new datastore.

You now need to select Storage > Add Storage

you should then see a LUN to select and format with VMFS-5 ?

did you check the LUN is visible to ESXi?

Host > Configuration > Storage Adaptors > Select iSCSI Software Adapter

you should see the LUN, that's been added

Is the LUN present?

Did you ensure, that the LUN was mapped to the IQN on the SAN ?

yes i did this but it is realy confusing.i did one experiment by installing a software SAN Storage on my lap top and created iscsi target.then i go to the esxi and put the IQN and tested.It was not working then for testing i check the port on my software SAN which was 3261 but in DYNAMIC DISCOVERY of the iscsi software adapter i did not change the port it was 3260.this time it quickly discover the storage.and i easily added the iscsi storage.
now the prob which i think is with the port of emc vnx storage.whats ur idea should i confirm the port as storage admin told me it is a default port 3260 but now with my test i am sure that it is bcz of the wrong port.how can i confirm the emc vnx port

the default port is 3260

When you tested connecting to Windows what port did you use there to test?

You have created the correct networking for iSCSI ?
