Operating System Software Instruction Manual

In an SLD Remote Copy configuration, a single Remote Copy group is copied directly to volumes
on two other systems by admitting the volumes to groups with two targets. Synchronous mode
Remote Copy is used between the primary (source) and backup system that are physically closer
to each other where a high bandwidth/low latency connection is shared. Asynchronous periodic
(periodic) Remote Copy is used between the primary system and backup system that are physically
farther apart and sharing a lesser connection. The synchronous connection must be a Fibre Channel
connection, while the asynchronous periodic connection can be either all Fibre Channel (over an
IP network) or all IP. Only unidirectional functionality is allowed between Remote Copy pairs.
NOTE: To configure SLD Remote Copy, you must have three available systems with configured
Remote Copy ports. At least two of the systems must have Fibre Channel ports.
To configure SLD Remote Copy:
1. In the Manager Pane, select Remote Copy.
2. In the Common Actions panel, select New Configuration.
The New Remote Copy Configuration wizard appears.
Targets
1. Under Select a Configuration, select Synchronous Long Distance.
2. Under Assign a System to Each Target:
• Select a storage system graphic. In the menu list, select a storage system to assign. Repeat
for the other storage system graphics.
NOTE: Only available systems, which satisfy requirements appear. For more information,
see the HP 3PAR Remote Copy Software User's Guide.
3. (Optional) Under Label Locations, enter a location for each storage server, for example, Lab
1, New York.
4. (Optional) Under Name the Target Systems, the Target Name fields are automatically populated
with the storage server names. You can enter an alternate name if you want.
5. Click Next.
Links
1. A graphical representation of each system's Remote Copy ports appears under Create Links.
Click and drag from a port on one system to a port on the other system. Repeat for the other
Remote Copy ports.
NOTE: You must use Fibre Channel links for the systems you plan to configure with
synchronous mode Remote Copy.
2. For IP links, in the IP Settings groups for each system/port, all fields are automatically populated
based on the link relationship you established under Create Links.
a. (Optional) Enter the gateway address for each system/port.
b. (Optional) Click Apply to test the link configuration, or Ping to test the communication
between the links.
3. For Fibre Channel links, in the Settings groups for each system/port:
a. Connection Type - Select Point for point-to-point mode or Loop for arbitrated loop mode.
b. Configured Rate - Select Auto (default), 1 Gbps, 2 Gbps, or 4 Gbps.
c. Click Apply to test the link configuration, or Ping to test the communication between the
links.
4. Click Next.
