bplist shows control file backup but rman "restore controlfile" fails with file not found

OK, I am trying to restore an Oracle database from a TOTALLY complicated setup and really need some help.

Overview: My production Oracle database server is actually a pair of Solaris servers running Symantec HA with one node active and one node in standby.  My backups are scheduled through NetBackup which calls an Oracle RMAN script to backup the databases.  Full database backups are generated every night and archive log backups are run at noon and 6:00 PM.  Backups go to a pair of DataDomain devices, one in my primary datacenter and one at my disaster recovery site.  At my disaster recovery site, I have a single Solaris server as a database server.  Finally, I have an Oracle RMAN catalog that runs on a Windows server.  This catalog is shut down twice a day and a Windows backup of just the RMAN directory is made, again to the DataDomain devices.

Now, I am testing my disaster recovery.  We have stopped the replication between the local and remote DataDomain devices.  I connect to the Unix server at the DR site and am attempting to recover the databases from backup.  We have added entries to the hosts files and created a No.Restrictions file so that the server at the DR site has access to the NetBackup backups.

When I run "bplist -C st31bora01 -t 4 -l -R /" at the DR database server, I see several backup files including the catalog backup I want (database files removed from the list for brevity).

I then try and use the following commands to recover the controlfile:

rman
set dbid = 1968089396
connect catalog rman10@RMANdb
connect target backup_dba
list backup of controlfile;
RUN
{
ALLOCATE CHANNEL CH1 TYPE 'SBT_TAPE';
SEND 'NB_ORA_CLIENT=st31bbl01,NB_ORA_POLICY=ORA_PASPROD';
restore controlfile;
}

Unfortunately, this does not work and I get the following failure:

Starting restore at 17-Oct-12 15:27:36

channel CH1: starting datafile backupset restore

channel CH1: reading from backup piece PASPROD_c-1968089396-20121014-01

failover to previous backup

I don't understand why it's not working.  The only thing I can see is that when I "list backup of controlfile", I see media ID's that are at the primary site as indicated by "Media: @aaaac".

RMAN> list backup of controlfile;

But when I go into the NetBackup Administration Console (at the DR site) and select NetBackup Management --> Catalog in the treeview on the left, I see all the Media ID's are "@aaaae".

Any help you can offer would be greatly appreciated.
