Create a Pairing

A LUN must be present before a pairing can be created.
Note
Caution We do not recommended using target entities in Read-Write mode as this poses a risk to the accuracy of
the data replication and may corrupt data recovery.
Once Async Replication pairing is setup, Increase Size and Delete operations are disabled on the Source
LUN used for the pairing.
The Async Replication Pairings window displays a table of LUNs and their host pairings. Information
about and the date and time of the last replication and the last restore is also displayed. From this
window, create new pairings using the top left-hand window button. On mouse hover over each pairing,
the replication schedule, and the source and target device info for that pairing appears in a pop-up box.
On right-click, an options menu appears for the selected pairing for the following:
