Hello,
I was browsing through the forums and came across yours. Emulex OneCommand Manager gives you the ability to manage Emulex and OEM Emulex adapters (e.g. NIC, FC, FCoE and iSCSI). In addition, you can view target information but you will not be able to interact with the array. Emulex OneCommand Manager for VMware vCenter Server plug-in might be a better fit for you as its specific for VMware 4.x and 5.x.

Also take a look at the Implementers Lab for more technical information regarding VMware and Emulex OneCommand Manager.

Hope this helps.
