Sbtbackup() failure and sbtrestore() failure

Question

Hi All,
I'm getting failures from sbtbackup() as well as failure from sbtrestore() for a successful backup. Below are the rman scripts which generate the errors, any help will be really appreciated -
For backup failure -
run {
allocate channel dev1_1 type 'sbt_tape' TRACE=1 format '%u_%p_%c'
parms='SBT_LIBRARY=/opt/CA/BABoraagt/libobk64.so,ENV=(PARENT_JOBID=335,SBT_PARMS=10.0.2.31;DGROUP0;26.01.07

backup full database include current controlfile; sql 'alter system
archive log current'; backup archivelog all delete input; release channel
dev1_1; }

RMAN-05016: failover to previous backup
For the failure from backup, errno=9 means "Bad file number" but don't know which file it's referring to. For restore failure, simply lost with errno=255.
Thanks a lot.

Answer 1

More likely the error is with the configuration of Media Manager. There could be various reasons.
What is your OS ????
