Hi Everyone,
I have read thread after thread on RDM and I now need to make a inquiry to the group. I have an ESXi 5.0 host with a 3ware 9650SE raid controller. After updating the driver ESXi now sees the 3ware controller just fine. I can format in VMFS and create 2TB vmdk volumes just fine. At this point there is no data on the array so I would like to experiment with RDM. My desire is to mount a 4TB RDM volume to a guest. I do not need snapshot or other VMFS features for this storage. As we all know, VMFS is now capable of larger than 2TB but VMDK's are still limited to 2TB.
If I go to my guest and create a disk the Raw Device Mode is always greyed out. All the RDM instructions on this forum indicate that a 4TB LUN is possible but from a SAN.
Is a 4TB RDM volume possible on an internal hardware raid controller?
Thank you!
