•
You cannot add new targets to a Synchronous Long Distance Remote Copy configuration.
•
The following restrictions apply:
A 1-to-N Remote Copy configuration can have a maximum of two backup systems. ◦
◦ In an N-to-1 Remote Copy relationship, a maximum of four primary (source) systems use
the same system as backup server.
◦ In order to configure Synchronous Long Distance Remote Copy, at least two of the systems
must have Fibre Channel ports. 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.
To create a Remote Copy target:
1.
Select Remote Copy in the Manager Pane.
2. Select the Remote Copy Configuration node in the Management Tree.
3. In the Common Actions panel, click Add to Configuration.
The Create Remote Copy Target wizard appears.
Targets
1. Under Select a Configuration, the current remote copy type will be selected.
2. Under Assign a System to Each Target, click a storage system graphic. In the menu that appears,
select a storage system to assign. Repeat for the other storage system graphic.
NOTE: Only available systems, which satisfy requirements appear. See the HP 3PAR Remote
Copy Software User's Guide for additional information.
3. (Optional) Under Label Location, enter a location for each storage server, e.g. 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 wish.
5. If both assigned systems are running supported HP 3PAR OS, the checkbox to Create additional
targets for simultaneous synchronous and periodic operations will be enabled and selected.
When Additional Targets for Multimode is selected, an additional target pair is presented
with the default target name of system followed by _1 and _2. You can change the target
name as desired, and there will be validation to make sure the target names on the same
system are unique.
At this point, if you reassign a system to one that runs a non-supported HP 3PAR OS, the
Additional Targets for Multimode will be deselected and disabled, and the additional target
pair will be removed.
6. Click Next.
Links
1. A graphical representation of each system's Remote Copy ports appears under Create Links
Between Systems. You will see the new target on the link.
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 Between Systems.
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.
