Do not take this for granted, but I think the iSCSI connections won't work (assuming you are using iSCSI). So doing a P2V may break that part and the machine will stop seeing the storage.

VMware uses an abstraction for that part and arguably , in VMware can be easier. As a matter of fact, our SAN and "expert" VMware guy, had a hard time helping me configuring our metal Cluster because that. He struggled configuring iSCSI for the SAN because and I will quote him, "it was easier on VMware".
