After configuring the cluster, use the SFW Configuration Wizard for Microsoft Failover Cluster to set up the SFW components for enabling support for live migration. SFW support for Hyper-V live migration is supported on a network within a Microsoft failover cluster. This wizard also enables fast failover support for SFW disk group resources in the cluster.

Enabling Hyper-V live migration support in a Microsoft Failover Clustering environment involves the following tasks:

Configuring SFW for Hyper-V live migration support using the SFW Configuration Wizard for Microsoft Failover Cluster
Enabling FastFailover attribute for SFW VMDg resources

You can launch SFW Configuration Wizard for Microsoft Failover Cluster from the Solutions tab in the Solutions Configuration Center (SCC). The wizard can be run from any node of the Microsoft failover cluster that has Hyper-V role added to it.

You can use the wizard for the following scenarios:

After configuring a Microsoft failover cluster for the first time or after adding a new node to the Microsoft failover cluster
For enabling FastFailover attribute for SFW VMDg resources
After removing a node from a Microsoft failover cluster
Reconfiguring live migration support in case of any change in the network properties

Note:

In synchronous mode of replication, if fast failover is set, then the RVG cannot be stopped and started when a disk group fails over to another node. If the RLINK is in hard synchronous mode, it may not be connected when the volume arrives, and the I/Os may fail. In such case, the Event Viewer displays NTFS and ReFS errors and file system reports the volume as RAW. Therefore, fast failover is not supported if the RLINK is in hard synchronous mode.
