What do I need to know before creating a mirrored pair?

Before creating a mirrored pair, follow these guidelines.

• You must have two storage arrays.
• Each storage array must have two controllers.
• The two storage arrays must be discovered in Unified Manager.
• Each controller in both the primary array and secondary array must have an Ethernet management port configured and must be connected to your network.
• 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.
• Asynchronous mirroring is supported on controllers with Fibre Channel (FC) or iSCSI host ports, while synchronous mirroring is supported only on controllers with FC host ports.
