Workflow for setting up external volumes

Before you begin setting up Universal Volume Manager, consult the topics in Planning workflow to make sure you have completed all planning tasks.

For VSP 5000 series:

1. Set up ports on the local and external storage systems. See the following:
   • Setting port attributes on the local system (VSP 5000 series)
   • Setting up ports on the external system
2. [Optional] Edit mapping settings before starting the mapping operation. For details, see External volume policy settings and functions.

   You can also make changes during the mapping operation or accept the default settings.

3. Map each external volume to an internal volume. The following settings are required:
   • Set the emulation type of the external volume to OPEN-V.
   • Set the number of LDEVs per external volume to 1.

   For details, see Mapping an external volume.

4. After an external volume is successfully mapped, perform the one of the following depending on the emulation type of the volume:
   • For mainframe emulations, format the volume or perform the Write to Control Blocks operation. For details, see the Provisioning Guide.
   • For OPEN-system emulation, define LU paths to hosts by using Device Manager - Storage Navigator, or namespaces on the NVM subsystem with an NVM subsystem port added for NVMe by using CCI. For details, see the Provisioning Guide.
     Note: To define a namespace for NVMe, CCI must be used. The operations cannot be performed from Device Manager - Storage Navigator. For more information about how to define the namespace for NVMe, see the Provisioning Guide or Command Control Interface User and Reference Guide.

For VSP E series:

1. Set up ports. For details, see Port setup (VSP E series).
2. [Optional] Edit mapping settings before starting the mapping operation. For details, see External volume policy settings and functions.

   You can also make changes during the mapping operation or accept the default settings.
