CADISK should fully perform the restore operation through the z/OSMF "restfiles" API when using the X-IBM-Migrated-Recall header. z/OSMF restfiles API starts a TSO address space in the background, and CA DISK prompts to confirm restoration. However, it is not possible to respond to a prompt in this environment. It should behave similar to automatic restoration when CA DISK does a RESTORE as a result of a batch job.
Failure message is attached.
