This document describes how to cross-reference (device mapping) IBM i disk units with VIOS disk units.
Resolving the problem
At some point, you may need to know the physical location of the virtual disk units. This information might be needed for performance measurements or service, or you might need to be able to translate to and from IBM i to VIOS to the physical devices (including an external disk, if relevant). This document describes how to map the i drives to the VIOS drives and then to the physical disks.
