As I couldnt wait, I decided to remove the vcenter from the Access/VMware tab. Once I did that, vCenter&ESXi disappeared from there, AND I found that all ESXi now appears in the Access/Host tab. I created a LUN via Storage/VMware tab, it choosed the LUN ids he wanted, but then I could modify the ID for all the host, 1 by 1. Not the best solution, but at leasts I could choose my IDs.  [NAME] know it shouldnt be a problem, but i dont like the word "should". Anyway, it's astonishing that you can not choose the LUN ID. I avoided the problem as stated before.  [NAME] I have alredy posted there my thoughts, thanks!     
Hello everybody,  Thanks in advanced for your help. I got a huge exp deploying VNX, but now I'm just deploying a new Unity 300. It's cool, mainly the integration with VMware, but i am facing a problem here.  I have an enviorement with a vCenter + 4 servers, two DS-4400M (EMC FC SW) and an old VNX, and now I want to present 4 new datastores from Unity to my ESXis, so I can start vmotioning VMs from the old VNX to the new Unity. Mi problem is that I'm not being able to find how to specify a LUN ID for the luns, and Unity choose whatever it wants, in this case 0. The problem is that my old VNX datastores are presented with LUN IDs from 0 to 8, so I'm worried about ID conflicts.  I have checked communities and KBs, and tried via Unisphere UEM CLI, but I cant not see anyway in which I can create the lun (GUI or CLI) choosing the LUN ID, either I cant find how to modify the storage group, which I cant see but I guess is there.  Any idea? Thanks a lot! [IMAGE]
Unity: storage groups, lun id?
