VMware & EMC: "sharing" a LUN between physical and virtual host
Posted on 2010-03-25
Is it possible to allow a physical host to access a RDM (Raw Device Mapping) LUN?
We want to share a LUN between a virtual host and a physical host. I mean, both running servers must be able to access this same LUN simultaneously.
We had to declare this LUN as a RDM, according to some VMware's PDF documentation ; to make it accessible from a virtual host.
Right now, the LUN is OK from our virtual host and is seen from the physical host as an unknown disk.
Hosts are both running W2k3 and we're use ESXi 4.
