I've been battling rman strangeness for some time. Every couple of days, messages like the following will show up in our rman logs:  

RMAN-00571: ===========================================================

RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============

RMAN-00571: ===========================================================


RMAN-12009: command aborted because some backup pieces could not be located

RMAN-12008: could not locate backup piece

RMAN-03009: failure of backup command on ORA_SBT_TAPE_1 channel at 06/02/2008 03:06:29

ORA-27192: skgfcls: sbtclose2 returned error - failed to close file

ORA-19511: Error received from media manager layer, error text:

   VxBSAEndTxn: Failed with error:

   The transaction was aborted.

ORA-19600: input file is backup piece
(/oraback1/flash_recovery_area/REMGT/backupset/2008_06_02/o1_mf_nnndf_TA G20080602T013340_4476rf8l_.bkp)

ORA-19601: output file is backup piece (91jhsnlt_1_2)  

Recovery Manager complete.  

We use veritas' netback to write to tape. Veritas reports everything as completing successfully.  

When I validate the backupset this piece is a part of, it validates properly:  

Backup Set Copy #2 of backup set 87489

RMAN>     Anyone know what is happening here? Anyone know if I can consistently and safely ignore this error stack?
