NOTE:

User can make use of the Expiration policy settings of HP 3PAR Recovery Manager in

which case those retained virtual copies are removed by the StoreServ after the expiration period
has elapsed.

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 name, 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 StoreServ
Storage Systems in the Remote Copy setup to be the default HP 3PAR StoreServ Storage
Systems.

CAUTION:

For Remote Copy to function correctly, the Remote Copy Storage Systems must

be default HP 3PAR StoreServ Storage Systems.

The Primary StoreServ should set as default on Primary backup server and the Secondary
StoreServ should be set default for Remote backup server.

If the Remote Copy HP 3PAR StoreServ Storage Systems are not default HP 3PAR StoreServ
Storage Systems, HP 3PAR Recovery Manager will not be able to locate the relevant Remote
Copy volume groups, and the Remote Copy operations will fail.

3.

After Remote Copy on two HP 3PAR StoreServ Storage Systems is set up, 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

HP 3PAR Recovery Manager supports Remote Copy in synchronous, , and asynchronous periodic
mode.

When 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, HP
3PAR 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, HP 3PAR Recovery Manager creates the virtual copy on a synchronous
Remote Copy system even if the policies on the primary server and backup servers do not
match.

NOTE:

For more information on specifying values at the time of creating virtual copies, see:

The sections on manually creating virtual copies in

“Using the Recovery Manager GUI”

(page 40)

The description of the HpRmCli Exch create command in

“Using the HP 3PAR

Recovery Manager for Exchange CLI” (page 64)

When using asynchronous periodic Remote Copy, HP 3PAR Recovery Manager virtual copies
can be created even if policies on the servers do not match. If policies do not match, the virtual
copies use the policies on the backup server.
