rescan ESXi 5.1 storage with dead / error paths

I have some datastores under 'Devices' showing 'dead or error / lost communication' in the vSphere client. They are not under datastores. This is on an HP P2000 G3 and a VNXe 3150. The VNXe is lost communication and the P2000 is dead or error. I cannot find the associated datastores on either SAN. It's like they don't exist. I know some datastores were created, mapped to hosts on the SANs, then deleted from the SANs before rescanning and adding the datastore to the ESXi hosts.

There are no networking issues on any host or either SAN. All VMs are running properly.

My concern is that if I rescan the hosts I will end up in a APD situation because of these errors.

Any insight into how to better troubleshoot this, and specifically, if someone could let me know if I will get an APD if I rescan, is greatly appreciated. To note I have refreshed without issue but not rescanned.
