Dell PowerVault MD 32XX/36XX Series Storage Arrays CLI Guide

All virtual disks might not be available for use in virtual disk copy operations. To determine which candidate virtual disks on the storage array can be used as a source virtual disk, use the show virtualDiskCopy sourceCandidates command. To determine which candidate virtual disks on the storage array can be used as a target virtual disk, use the show virtualDiskCopy targetCandidates command. These commands return a list of the expansion enclosure, slot, and capacity information for source virtual disk and target virtual disk candidates. You can use the show virtualDiskCopy sourceCandidates and the show virtualDiskCopy targetCandidates commands only after you have enabled the virtual disk copy feature.

A source virtual disk can be a standard or thin virtual disk. A target virtual disk can be a standard or thin virtual disk in a disk group or disk pool and, if the legacy version is enabled, a legacy snapshot base virtual disk.
