I guess this is caused by the lack of capability.
Please check if enough capability was added to

Thanks, all the test in SCSICMD.exe can pass now, when I set the ep

We found that sg_persist --read-keys can't get the same result in VM
and host, and now we get the same result in both VM and host mode.
But Windows 2008 Failover Cluster Still can't get the cluster disk

Sometimes I can see the lun which passed to the vm, sometimes not.
