This appendix provides an example walkthrough of the SRDF/Metro interface with Unisphere for PowerMax 9.0. The following operations are covered in the examples:
Create new Devices on Source and Target Arrays
In this section, we will create new source and target volumes which will be added the active SRDF/Metro group. Navigate to the Storage, Volumes section and follow the create wizard to create appropriate primary side devices (R1). You will then select the secondary array (0191) and do the same to create the secondary devices (R2).
Verify SRDF/Metro Group is currently Active
On the primary array (0130), choose Data Protection, Storage Groups, SRDF, to verify that the MetroApp1 storage group mode is active.
Perform Createpair –Exempt operation with active SRDF/Metro Group
To add the previously created devices to the SRDF/Metro active configuration, choose Data Protection, SRDF Groups, select the MetroRDFG group, then the Create Pairs option above to enter the appropriate wizard to add new devices to the chosen SRDF group.
Display updated SRDF/Metro Group with Newly Added Devices
To verify the devices were added successfully, navigate to Storage, Storage Groups, choose MetroApp1 and verify that it now contains the additional devices.
