Hi all,
I'm newbie about 3par.
I had 4 Hyper-v Host and i config raid 1 thin and export one volume on 4 hyper-v host for store VMs on that. I stuck on issue when i store VMs on this Volume. This volume often error and after that all VMs store on this failure. I had turn on MPIO feature and health check on 3par and everything ok.
But i know why i still error on volume
I appreciate about all answers.
Sorry about my bad english.
Thanks all.

Try turning off odx. It's a non-feature, and causes tons of issues

If ODX doesn't solve your problem, check the VMQ feature if you're on HP hardware with Emulex drivers and are using iSCSI. Disabling this turned my Hyper-V rig stable again. VMQ mostly hurt my vSwitches though.

Turn off all VMQ on a host: get-netadapter | disable-netadaptervmq

Of course, have your environment's firmware up-to-date at all times.

Also, be sure to get every update and recommended hotfixes for Windows 2012(r2) failover clusters:

Oh, and check if your Windows hosts have the right persona.
