What do you see in the vSphere client under Configuration - Storage Adapters when you select the LUN under Details, and then right-click and select Manage Paths ?
Do you also see the 4 paths ? And does each of the paths have a Status Active ?
It looks as if your storage device has 2 storage processors.
See Cormac blog post Ye olde Controller, Target, Device (ctd) Numbering for some more info on this.
