Create asynchronous mirrored pair

To configure asynchronous mirroring, you create a mirrored pair that includes a primary volume on the local array and a secondary volume on the remote array.

Before you create a mirrored pair, meet the following requirements for SAN Manager :
  • The Web Services Proxy service must be running.

  • SAN Manager must be running on your local host through an HTTPS connection.
  • SAN Manager must be showing valid SSL certificates for the storage array. You can accept a self-signed certificate or install your own security certificate using SAN Manager and navigating to Certificate > Certificate Management.
Also be sure to meet the following requirements for storage arrays:
  • Each storage array must have two controllers.
  • The two storage arrays must be discovered in SAN 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 11.60.2. (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.
  • Your local and remote storage arrays are connected through a Fibre Channel fabric or iSCSI interface.
  • You have created both the primary and secondary volumes that you want to use in the asynchronous mirror relationship.

The process to create an asynchronous mirrored pair is a multi-step procedure.
