RMAN -06100: no channel to restore a backup or copy of datafile 51

Question

Oracle 10.2.0.4
I am attempting to duplicate a database from a full backup that was written to tape. I connect to a catalog, the target, and an auxilliary database. I allocate channels for disk and allocate auxiliary channels. For testing purposes I am trying to restore one data file from tape to disk but get RMAN-06100.

RMAN-06026: some targets not found - aborting restore
RMAN-06100: no channel to restore a backup or copy of datafile 51

Answer 1

Here is some additional information:
6100, 1, "no channel to restore a backup or copy of datafile %d"
// *Cause: A datafile, tablespace, or database restore could not proceed
// because the backup of the indicated file exists on a device type
// that was not allocated for restore.
// *Action: None - this is an informational message. See message 6026 for
// further details.
what do i need to do to correct this: backup of the indicated file exists on a device type that was not allocated for restore
