Adding a HyperSwap relationship to an existing 3-site consistency group
You can add existing HyperSwap relationships that are configured between the near sites to an existing 3-site consistency group. If you are using Orchestrator 3.0, The HyperSwap relationship must be empty and cannot contain volumes with active data. HyperSwap relationships must be in the consistent synchronized state before they can be added to a 3-site consistency group.
Orchestrator 4.0 supports the ability to add a HyperSwap relationship with data to existing 3-site consistency group. If you are running Orchestrator 4.0, see Adding a HyperSwap relationship with data to 3-site consistency group.
Using the management GUI
You can view and manage HyperSwap relationships on the Remote Copy page, but HyperSwap relationships are created automatically during the HyperSwap volume creation. To view current HyperSwap relationships on the system, select . HyperSwap relationships are listed in the management GUI with the type, activeactive, and must be in the consistent_synchronized state before they can be converted to a 3-site consistency group.
To add an existing HyperSwap relationship to a 3-site consistency
group, complete these steps:
- In the management GUI, select .
- Select Independent Relationships and right-click the relationship and select Convert to 3-site.
- Uncheck the This relationship contains data checkbox.
- Select the 3-site consistency group from the list that displays and select Next.
- Under Choose a pool, specify the numerical ID for the storage pool on the auxiliary-far site that provides capacity for the target volumes. To verify these details, select Launch the Aux-Far management GUI, and select . If the selected pool is a data reduction pool, select This is a data reduction pool.
- Under Aux-Far pool settings, select the method for saving capacity that this pool uses.
- In the Volume base name field, enter a naming convention that identifies the volume as part of the 3-site consistency group. The names are automatically generated to include the specified base name, the name of the 3-site consistency group, and an incremental number.
- Click Convert.
- After the conversion completes, verify that the HyperSwap relationship is part of the 3-site consistency group. Select the 3-site consistency group and verify that the new relationship displays in the list of relationships.
Using the command line interface
To add a HyperSwap (activeactive) relationship to an existing 3-site consistency group, complete these steps:
- Run the mkvolume command to create an empty
volume.
# svctask mkvolume -pool Pool0:Pool1 -size 5048 -unit mb -name Hyperswap_Volume Volume, id [8], successfully created - Run the lsrcrelationship command on the HyperSwap relationship to verify that the state of the relationship is
consistent_synchronized.

consistency group where the stand-alone relationship is to be
added.
