First, log on to Dell Equallogic SAN, create a new Volume (we separate between the boot volume, 100GB LUN, thin provision, OS sees only 60GB) and a new Data volume (same settings like the boot volume).
Once done, went to our ESX servers from Vsphere client->Configuration tab->chose Storage adaptor and rescan fornew storage devices and new vmfs volumes (so the ESX can 'see' the new LUNs on the SAN).
Once done, go to STORAGE and Add new storage -you should be able to see the new LUNs.
(I then got an error: multihost access is not enabled for this target - missed a check box on the SAN while creating the LUN).
that's it. now you should be able to create a new VM and point it's file to the respective LUN(s).
