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 or iSCSI interface.
- 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.
- Your storage array must contain at least one mirror consistency group. You create a consistency group in Unified Manager in the Create Mirrored Pairs wizard.
