Before you map external volumes to the local storage system, review the information about the planning workflow to ensure that you understand the Universal Volume Manager requirements and implementation procedures.
Follow this general order to prepare for Universal Volume Manager:
- Review System requirements.
- Verify that the external storage system whose volumes you want to map is supported by Universal Volume Manager. See Appendix A, Special settings required for certain supported external storage systems.
- Verify that the functionality you want is supported for mapped external volumes. See Supported software for external volumes.
- In the external storage system, select a port and set parameters, as necessary. See Setting up ports on the external system.
- In the local storage system, identify the port to be connected to the external storage system and make sure it is specified as an external port. See Setting port attributes on the local system (VSP 5000 series).
- Plan data paths from the local storage system to the external storage system. See External paths, path modes, and configurations.
- In the external storage system, prepare volumes for use in the local storage
system. For example, if you plan to use an external volume for replication, verify that it
meets the requirements for replication software.
For instructions and additional information for VSP E series, see External volume requirements.
For instructions and additional information for VSP 5000 series, see:
- In the local storage system, configure the external volume groups to which you will assign the external volumes during the mapping operation. See External volume groups.
- Optionally, change the default values of the mapping settings before performing the operation. See External volume policy settings and functions.
