Replication-enabled volumes can be created using a combination of PowerShell and Failover Cluster Manager or by using Windows Admin Center.
For each replica-enabled volume, you need a corresponding log volume on both sites (with a minimum of 8 GB in size) and an equivalent replica volume on the secondary site. The log volume is used to serialize writes for replication.
The following table shows the volumes that are must create a 1 TB replica volume:
Once a replicated volume is created, go toto verify the status of the replica traffic encryption.
See Appendix A for the correct PowerShell Cmdlets and Failover Cluster Manager steps to create the volumes shown in this table. It is recommended that you create two-way mirrors for all volumes to improve write performance and capacity efficiency.
For a planned site failure, when the volume replication direction is reversed, the disk reservations on the secondary site for Replica Volume and Replica-log volumes are removed and moved to the primary site. Source Data and Source Log volumes are given the disk reservations and become active on the secondary site. After 10 minutes, the virtual machines residing on the primary site associated with the migrated volume automatically Live Migrate to the secondary site.
