@Ajal,
When you submitted a delete command from rman, it will only delete the backup information from control file and catalog. It couldn’t delete backup physically from commvault storage because external pruning is disabled.
You can validate with the job id’s.
Are the backups running through commvault schedule? If yes, each backup will have unique piece names starting with the job id’s.
Check which pieces pruned from Oracle when submitted delete command, compare the same in commvault under job history using job id’s of pruned backups.
Let us know in case of any questions.
