I have a san that has been replicating offsite and attempting to perform a restore. I build a similar esx host to that of my production environment and I managed to mount the datastore to the esx host and I am able to see the vdmk files and inventory the vms. One of the vms has a rdm and while I can see the rdm file in the datastore when I tried to add it to the VM, the Raw Device Mapping is greyed out.
I have tried everything but I am not successful in mapping the rdm. Any assistance will be appreciated. I am running esx 5.x
