Hi Experts,

HP backup application invokes RMAN backup script like

run {
allocate channel 'dev_1' type 'sbt_tape';
backup incremental level filesperset 1

And during execution folowwing error appear:

Recovery Manager: Release - Production

RMAN-06005: connected to target database: CIS (DBID=3980547323)

RMAN-10031: ORA-19624 occurred during call to DBMS_BACKUP_RESTORE.DEVICEALLOCATE

When I'm trying to change type of channel to 'disk', -
all command completed succesfully.

Maybe Oracle need some modification to support SBT_TAPE type or something?

Thanks in advance.
