Hi

You must use RDM. Otherwise is not supported. SCSI commands is the reason. 

Furthermore on some versions I managed to crash the ESXi as well.

If you have a 2-3 node cluster how do you share the disks across?  Do you have VM’s with their own VMDK’s (if not RDM) in each node or is there some way to share access to the same VMDK’s?  What are the advantages doing this other than existing HW use?  Seems to me for a lab environment or very small nonperformance focused implementation this may be a viable option.
