Mirror volumes asynchronously

With the Asynchronous Mirroring feature, a volume can have two physical copies, which facilitates data availability and minimizes downtime. Every asynchronous mirroring relationship involves one volume in a primary role and one volume (on a different storage array) in a secondary role.

  • Create asynchronous mirrored volume
    You mirror a volume asynchronously to maintain data at the remote storage array to be a point-in-time consistent copy of data at the local storage array. You do this by creating a mirror consistency group to establish the mirroring relationship between the two storage arrays, and then selecting the primary volume and secondary volume that you want to use in the mirror.
  • Complete mirrored pair for primary volumes created with AMW
    If you created a primary volume on a storage array managed by ThinkSystem Storage Manager 's Array Management Window (AMW), you can create the secondary volume with ThinkSystem System Manager .
