two are created that count against the logical drive limit.
The number of supported mirror definitions is dependent on the hardware in your storage subsystem. Refer to the initial setup

Make sure that the switch fabric is configured appropriately before you start this procedure.
Reservations on secondary logical drives are blocked. However, reservations on primary logical drives are allowed.

Preview of the Activate Enhanced Remote Mirroring Wizard
After you enable the RM premium feature and before you create a remote mirror, you must activate the RM premium feature. This list describes some of the dialogs that you will encounter when you use the Activate Enhanced
Remote Mirroring Wizard:
The Activate Enhanced Remote Mirroring Wizard - Introduction dialog lets you select the free capacity or the unconfigured capacity node on which to place the mirror repository logical
drives.
The Activate Enhanced Remote Mirroring Wizard - Create Array dialog lets you specify a new where the mirror repository logical drives will reside.
