What do I need to know before creating a mirror consistency group?

You must have the browser-based ThinkSystem SAN Manager installed, and have discovered the two storage arrays you want to mirror data between. Then, from SAN Manager , you select the primary volume's storage array and click Launch to open the browser-based ThinkSystem System Manager .

In addition, make sure of the following:

• 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 must have two storage arrays.
• Each storage array must have two controllers.
• You must know the password for the local and remote storage arrays.
• Your local and remote storage arrays must be connected through a Fibre Channel fabric or iSCSI interface.
