To perform server-free data movement, a path must exist from the datamover to both the disk and the drive. If either path is not defined or is offline to all datamovers defined then the data movement cannot occur via server-free.
The operation continues using another method.
Define the appropriate paths from a datamover to the disks and drives. If a path is defined from a datamover to a drive in a library then all drives in that library should have paths defined from that same datamover. A path may have to be updated to specify online=yes.
