Rman backup excluding missing archivelogs

Question

Please help me in the following scenario :
I have 2 months old archivelog in my disk..am taking full rman database backup daily at night..but not the archivelog. once I moved some of my archivelog files to another mount point as the archivelog destination is almost filled.
when i try to take the backup of archivelogs,I got the message
RMAN-00571: ===========================================================
RMAN-03002: failure of backup command at 11/24/2008 23:16:23
RMAN-06059: expected archived log not found, lost of archived log compromises recoverability
ORA-19625: error identifying file /archv/PROD/PROD1_234_662754021.arc
ORA-17503: ksfdopn:4 Failed to open file /archv/PROD/PROD1_234_662754021.arc
ORA-17500: ODM err:File does not exist
which is expected, since I moved the file /archv/PROD/PROD1_234_662754021.arc to another location inorder to have that as a temp.solution ..
now , I have all my archivelogs starting from nov-3 till date in the log_archive_dest_1
RMAN> run
ALLOCATE CHANNEL ch00 TYPE 'SBT_TAPE';
ALLOCATE CHANNEL ch01 TYPE 'SBT_TAPE';
BACKUP FORMAT 'arch_u%u_s%s_p%p_t%t'
Archivelog
FROM TIME "TO_DATE('11-03-2008:23:46:15', 'MM-DD-YYYY:HH24:MI:SS')"
UNTIL TIME "TO_DATE('11-24-2008:23:46:15', 'MM-DD-YYYY:HH24:MI:SS')"
DELETE INPUT;
release channel ch00;
release channel ch01;
now, is there anyway i can include the old archivelogs in the rman by restoring from the temporay location and taking backup. I know that I have a full database backup, but I need to have my old archivelogs also included in that ? or () does backup arhcivelog all will give any error message now ?(ORA-17500: ODM err:File does not exist)
Any way ?

You need to unregister the old archivelog path and register the new archivelog path for the backup to be successful without changing the backup command.
Assuming you're using 9i or 10g (although 'SBT_TAPE' hints 8i), you can either
1. use the 'change' and 'catalog' command to unregister the archivelogs from the old place and re-register the archivelogs in the new place:
change archivelog 'oldpath\archivelogname' unregister';
catalog archivelog 'newpath\archivelogname';
or
change archivelog 'oldpath\archivelogname' unregister';
catalog start with 'newpath';
2. Not include the archivelog clause in the backup (not recommended)
I generally backup archivelogs at least 2-3 times before deleting them and make sure they are on seperate tapes (if possible). Deleting on input has one point of failure.
