Resuming a Mirrored Pair

Use the Resume Enhanced Remote Mirroring dialog to resume data transfer between a primary logical drive and secondary logical drive participating in Enhanced Remote Mirroring, after the mirror has been suspended or unsynchronized.

The Resume Mirrored Pairs option enables you to control when the data on the primary logical drive and the secondary logical drive should be synchronized. This ability helps to reduce any performance impact to the host application that might occur while any changed data on the primary logical drive is copied to the secondary logical drive.

After the mirrored pair is resumed, only the regions of the primary logical drive modified since the mirrored pair were suspended are written to the secondary logical drive.

Frequently Asked

What is a write consistency group?


Attention:

Possible loss of data access – If the selected mirrored pair is part of a write consistency group, you automatically suspend all mirrored pairs in the write consistency group. Use the command line interface to resume single write-consistent mirrored pairs.

Any data that is written to the primary logical drive is logged while the mirrored pair is suspended and is automatically written to the secondary logical drive when Enhanced Remote Mirroring is resumed. A full synchronization is not required.
