Mirroring a device

About this task

You can mirror a device locally or remotely. When you add a local mirror, a device in the local cluster is used to create a RAID-1 device. If the local device you are mirroring is already a RAID-1, the mirror is added as another leg. For a remote mirror, a device in the remote cluster is used to create a distributed device. You can mirror a device with or without a volume on top.
NOTE When creating a remote mirror, the mirror must not be in a consistency group.

    1. In a metro node Local:
