Volume instance mapping API

Edit online

In PowerVC, you can look up the backend resources that are related to the volume connections for a virtual machine. The API attempts to provide the following data if applicable: Virtual I/O Servers, Fibre Channel ports, shared storage pools, block device mappings, and zones that are associated with a volume to a given virtual machine.

Backend Storage Resource Mapping (APIs)

The following API can be called against a specific volume or virtual machine:
Table 1. Table 1. Volume Instance Mapping APIs
Method URI Description
