Microsoft Failover Cluster (MSFT) on Nutanix | Nutanix Community
Skip to main content

With AHV-20190916.189, Nutanix supports Directly Attached Volume Groups in a Guest VM Cluster. On AHV clusters, you can create a guest VM cluster by directly attaching a volume group to guest VMs.

After you attach a volume group to guest VMs, vDisks appear as SCSI devices to the guest operating system and you do not need to set up any in-guest connections when you are creating a guest cluster. If you directly attach volume groups to guest VMs, you can seamlessly share vDisks across VMs in the guest cluster.

You can directly attach a volume group to guest VMs to create the following guest clusters:

1. Microsoft Failover Cluster (MSFT)

2. Red Hat Enterprise Linux (RHEL) Cluster

Acropolis Release Notes

hello, I'm trying to implement a Microsoft cluster for a client using volume group and creating the disks necessary to mount the SQL Server, I can see the disks in the two members of the cluster but when I try to migrate the resource to another node the resource is offline and I can't go up again.

The AHV is in version 20190916.410, would the recommendation be to use volume group atached on the VM or to deliver via ISCSI?

The error when I try to put the resource online is 0xaa resource in use, the documentation I read says that it is necessary to be with virtIO in version 1.4.x but that version is not available for download, can you give me a help?

How would I implement a failover cluster over two datacenters and two Nutanix Clusters where I also have different IP-Adresses? 

Can this be done with AHV and Metro?

Finally got it solved.  I was exactly same place as Diego.  “...when I try to migrate the resource to another node the resource is offline and I can't go up again.”

So all documentation explains the iSCSI Initiator yet nothing explains the part you need to do before that.  Add Roles and Features > Install feature “Multipath I/O” and go into it.  There you will see the option to enable iSCSI support devices.  That’s it, just check that box, nothing else.  Now after that confirm iSCSI initiator and now it will pass the cluster validation report and the cluster will be able to control it.
