sounds like a bug.  try oracle support.  if the original backup command backed 
it up, and the backup is part of the catalog already, the backup archivelog 
delete all input shouldn't think it still needs to back it up.     it is 
confused apparently, and not including this backup in its calculations about 
what it still needs.

from your "list" command, it seems it is aware of the backup from a reporting 
perspective, but not from a calculation about what needs to be backed up.  

probably two separate code paths.  produce a simple test case that reproduces 
this and send it to support.

1.  generate a bunch of log switches
2.  backup logs until sequence x delete input
3.  generate some more log switches, backup archive log delete all input

if you get the error, it must be a bug (or a consequence of #2 that should be

Subject: RMAN backup of archived log fails

G'day all.

I've spent all day yesterday and today trying to figure this out - but 
no luck. Has anyone seen this before, or maybe a hint where to look? 
I've tried all Oracle doco, google, the list archives, etc. (but maybe 
my search terms are off..)

Versions are:

Oracle RDBMS (both target, catalog and RMAN itself)
NetBackup: 5.1
Target OS: MS Windows 2003 sp 1
Catalog OS: RedHat Enterprise Linux 4

Some time ago we ran out of space on our archive log destination, due to 
ongoing problems with NetBackup and the Dell tape libraries.. that's now 
fixed and we backup up the archived log files by specifying sequence 
ranges (via NetBackup), as in

RMAN> backup archivelog until sequence #### delete input;

All backlog files are now backed up, but when we run the normal job, 
which has "backup archivelog all delete input", it fails complaining 
that it cannot find a file which was backup up with the sequence limited 
command. This is the error:

released channel: ch00
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================

ORA-27041: unable to open file
OSD-04002: unable to open file
O/S-Error: (OS 2) The system cannot find the file specified.

Both the database and the catalog say that the file it complaints about 
are backed up:
