original is placed in the recycle bin so that it can be retrieved if necessary. During this time, the activated DR volume continues to accept

IO.

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.
