Setting Up Remote Copy
1.Install and configure Remote Copy. For more information, see the HP 3PAR Remote Copy Software User’s Guide.
NOTE: Be sure to configure the backup server with the same names, structure, and Windows authentication mode settings as the primary server.
2.Use the provcfg.exe tool (HP’s hardware provider tool) to configure the HP 3PAR Storage Systems in the Remote Copy setup to be the default HP 3PAR Storage Systems.
CAUTION: For Remote Copy to function correctly, the Remote Copy Storage Systems must be the default HP 3PAR Storage Systems.
If the Remote Copy HP 3PAR Storage Systems are not the default HP 3PAR Storage Systems, Recovery Manager will not be able to locate the relevant Remote Copy volume groups, and the Remote Copy operations will fail.
3.After you have set up Remote Copy on two HP 3PAR Storage Systems, create a Remote Copy volume group for testing purposes.
4.Configure the Remote Copy volume group for synchronization either in synchronous mode or in asynchronous periodic mode with a period value of zero.
Support for Remote Copy Modes and Policies
Recovery Manager supports Remote Copy in synchronous and asynchronous periodic mode.
•If you are using synchronous Remote Copy, the policies on the production system (the Remote Copy primary system) and the backup system must match. If the policies do not match, Recovery Manager cannot create virtual copies on a synchronous Remote Copy system.
However, if you manually specify an expiration value, a retention value, or both when you create a virtual copy, Recovery Manager creates the virtual copy on a synchronous Remote Copy system even if the policies on the primary and backup servers do not match.
NOTE: For more information on specifying values at the time you create virtual copies, see:
◦The sections on manually creating virtual copies in “Using the Recovery Manager GUI” (page 29)
◦The description of the RMExch create command in “Using the Recovery Manager CLI” (page 51)
•If you are using asynchronous periodic Remote Copy, you can create Recovery Manager virtual copies even if policies on the servers do not match. If policies do not match, the virtual copies use the policies on the backup server.
•If you are running Remote Copy in a Synchronous Long Distance configuration, the virtual copies on the synchronous and asynchronous periodic Remote Copy backup servers do not have the exact same timestamp.
Support for GeoCluster for Microsoft Windows
Recovery Manager for Exchange supports the use of both Remote Copy and HP 3PAR GeoCluster Software for Microsoft Windows:
•When synchronous mode Remote Copy is used with Recovery Manager for Exchange and GeoCluster, you can use Recovery Manager to create virtual copies on both the production system (the Remote Copy primary system) and the backup system.
•When Synchronous Long Distance Remote Copy is used with Recovery Manager for Exchange and GeoCluster, you can use Recovery Manager to create virtual copies on all three systems:
