5 Server at source site (not mapped) 6 Server at DR site

Step 5B: The Activated DR Volume is Deactivated

After the replication from the activated DR volume to the original source volume is synchronized, Storage Manager 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.

Step 5C: The Source Volume is Activated

Storage Manager prompts the administrator to deactivate and unmap the destination volume. The source volume resumes replicating to

the destination volume, and the source volume is activated and mapped to the server at the source site.
