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

You configure mirrored pairs in the SAN 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 11.50. (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 SAN Manager. Mirrored pairs are configured in the SAN Manager interface.
• The two storage arrays are discovered in SAN Manager.
• Your storage array must contain at least one mirror consistency group. You create a consistency group in SAN Manager in the Create Mirrored Pairs wizard.
