Issues with cluster shared storage adding disks?

I'm playing with some equipment an ran into an interesting issue... something new I've never seen or heard of.

Two X8 systems (fat twin) each with:
LSI 8E HBA's flashed to IT mode,
2012R2 fully updated.
On My Domain
8088 into a DataOn 2.5"JBod.
both clustered with HyperV and storage roles installed.

Currently they have nothing on them do only 1GBE on a dumb switch that's shared to a separate DC

Seems like a good setup a shared pool of disk and some HA VM's right...?

Problems arise when I run cluster validation, few minor warnings (I'll post them in next post)

in particular the disks are visable from each node and seem to be OK, but when added to clustered storage they are marked "failed" but I know there is NO WAY they are all bad.

there are 4x PERFECT S3500's
4x 32GB Intel SLC's
4x 500GB sata
2x4TB


My end goal is to populate like so:
2x 2TB 4x4TB 3.5's per node
This will be for Boot and archive. (I might even put in 4x 8TB archive drives)
8088's to the JBOD for VM storage as well as my exchange and a few DB' used in house.
the Jbod will have :
4x s3500, I might up it to 8 units
Maybe? the 4x 32SLC's for hot writes.
then I'll fill the rest with the piles of 1TB spinners I have, eventually going to 4TB or SSD's as needed.

Testing has completed Passfully. The configuration appears to be suitable for clustering. However, you should review the report because it may contain warnings which you should address to attain the highest availability.

The issues for sata drive is they can not handle scsi reservation, means in a cluster environment they will always fight for the resource and cause the storage to go offline. It should work as a standby node. When the primary go offline, you can always mount the volume to the new node. You need to share the folder again. It should retain ntfs permissions.

Any reason ha is required on the storage level?

If you want the ability to move vm between 2 nodes on hyper-v, maybe one node as storage and both can be hypervisors.
