You configure mirrored pairs in the Unified Manager interface, and then manage the pairs in System Manager.
Before creating a mirrored pair, follow these guidelines:
You must have two storage arrays.
Each storage array must have two controllers.
Each controller in both the primary array and secondary array must have an Ethernet management port configured and must be connected to your network.
Your local and remote storage arrays are connected through a Fibre Channel fabric.
The storage arrays have a minimum firmware version of 7.84. (They can each run different OS versions.)
You must know the password for the local and remote storage arrays.
You must have enough free capacity on the remote storage array to create a secondary volume equal to or greater than the primary volume that you want to mirror.
You have installed the Web Services Proxy and Unified Manager. Mirrored pairs are configured in the Unified Manager interface.
The two storage arrays are discovered in Unified Manager.
