When you use library maintenance to copy files from one library maintenance tape to a new library maintenance tape, the disk family names in the directory for the new tape are the same as those in the original tape directory. The tape directory of a library maintenance tape created by an NFT file transfer from one host to a tape at another host will contain the original disk family names, but not the original host name. A restore from such a tape will attempt to copy the files to the disk families with the proper names at the host where the restore statement is executed.

If you attempt to use a RESTORE statement with one of these tapes, you will receive the following error message and the RESTORE process will terminate:

MT <unit number> TAPE DIRECTORY DOES NOT CONTAIN DISK
FAMILY NAMES, RESTORE TERMINATED
