When GAD setup is complete, the host sees the P-VOL and S-VOL of each pair as a single volume in a single storage system. Resource groups are created in the secondary storage system using the primary storage system's serial number and model as virtual information, so that the P-VOL and S-VOL of each pair share the same virtual storage machine information.
- If a P-VOL is registered on a virtual storage machine, make sure to create the virtual storage machine on the secondary storage system using the same model and serial number as the virtual storage machine with the P-VOL registered.
- All resource groups must be assigned to the users of VSP One Block Administrator and the REST API. If any of the resources is not assigned, these management tools cannot be used. Make sure that you assign all resource groups to the user groups containing the users of these management tools if you want to use the management tools in an environment with resource groups.
A virtual storage machine is composed of multiple resource groups that have the same virtual information. When you create a resource group and specify the virtual serial number and model, the resource group is registered in the virtual storage machine. If the virtual storage machine does not already exist in the storage system, it is created automatically when the resource group is created.
