Unisphere and Unisphere Central 2020 R1 Administrator's Guide

Step 5B: The Activated DR Volume is Deactivated

After the replication from the activated DR volume to the original source volume is synchronized, Unisphere Central prompts the administrator to halt IO to the secondary volume.

NOTE IO must be halted before the destination volume is deactivated because the deactivation process unmaps the volume from the server.
