Can I use pass-through disks in a Hyper-V cluster to eliminate the VHD size limitation?
Posted on 2010-09-08
I'm stuck in a situation where I'm going to create a Cluster Shared Volume (CSV) to host 4 VMs. Unfortunately, one of these VMs needs a data disk larger than 2 TB so that means I can't use a VHD as the VHD size limitation is 2 TB.
I figured I would create a pass-through disk. What I don't know is... can I do this in a clustered configuration? In other words, will the pass through disk follow from host to host assuming the zoning and LUN configuration is done properly?
The confusing part to me is... from the host perspective, the pass through disk must be OFFLINE. I'm not sure an offline resource can follow/fail from node to node.
Is this a legitimate configuration? Can I have as many disks/VHDs as possible on the Cluster Shared Volume and then have this one pass through disk for one of the VMs hosted on a separate LUN and have the cluster work?
Hopefully this makes sense. Let me know if you need any additional data to help answer.
