iscsi storage

I am using dell equalloc ps 6000 with firmware version V6.0.2(R287892). I am currently using Storage Link for my SR's. Noting that this is being deprecated. I configured another equallogic using iscsi. The problem i have now is the the volume does not itemise the contents of my iscsi volume. i have to go to xenserver to check on these. storage link used to give me the ability to check on an individual vdi and adjust space as required. Do i have to create an iscsi SR for each vm? i created on huge SR and that is where i dumped all the vms but cannot see them individually. i hope i am making sense. Please advise. In short i would like to have an iemized view of my vdi on equallogic the way storage link does it.
