You configure mirrored pairs in the SANtricity Unified Manager interface, and then manage the pairs in SANtricity 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.
