Use Remote Mirroring to create a copy of a primary logical driveon another, secondary storage subsystem. Creating a copy of a logical drive at a remote location gives you a backup of your data that can be accessed in case of catastrophic data loss at the primary site.
The Create Remote Mirror wizard helps you to quickly define a primary logical drive and a secondary logical driveand synchronize the data between the two logical drives.
Important: Not all controllers have the capability to create and support a Remote Mirror. Controllers must have dual, host-side interface ports in order to use this feature. Consult your hardware documentation for more information about your controllers.
Before using this wizard, make sure the following requirements have been met:
Ensure the storage subsystems containing the two logical drives you want to mirror are connected together through a Fibre Channel fabric interface.
Enable the Remote Mirroring premium featureon both storage subsystems (primary and secondary) using a feature key.
Activate the Remote Mirroring Feature on both storage subsystems (primary and secondary) using the Storage Subsystem >> Remote Mirroring >> Activate pull-down menu option in the Subsystem Management Window.
Note: You can launch the Create Remote Mirror wizard if you haven't activated the Remote Mirroring premium feature on the local storage subsystem. However, an error dialog is displayed, "Remote Mirroring Not Activated". From this dialog, select the Activate button and the Activation wizard is started. After you have activated the feature on the storage subsystem, restart the Create Remote Mirror wizard.
Ensure the secondary storage subsystem contains a logical drive that is greater than or equal to the capacity of the primary logical drive in the mirrored pair.
Procedure
1
Select a logical drive in the Logical View and then select Logical Drive >> Remote Mirroring >> Create pull-down menu option or select Create Remote Mirror from the right-mouse pop-up menu.
Result: The Create Remote Mirror - Introduction screen is displayed.
2
Follow the directions on each of the screens and press Next when ready to move to the next screen.
Note: Each wizard screen has context-sensitive help. Press Help to receive help appropriate for that particular screen.
A Preview of the Create Remote Mirror Wizard
After enabling the Remote Mirroring premium feature and activating it on both the primary and secondary storage subsystems, you can create a Remote Mirror. The following describes some of the screens you will encounter when using the Create RemoteMirror Wizard:
The Select Storage Subsystem screen allows you to select the storage subsystem that contains the secondary logical drive to be included in the mirrored pair.
The Select Secondary Logical Drive screen is used to select the secondary logical drive to be included in the mirrored pair.
The Set Synchronization Priority screen is used to set the synchronization priority level for the mirrored pair.
