You're trying to fit a round peg in a square hole. Why do you want to implement locked cannister mode? Security? A backupset *can* be read without a db backup, as long as you're dealing with like OS platforms. They're much less secure than an offsite pool. Exports are similarly insecure. Data from TSM's offsite tape pools cannot be read without a current database backup and other required TSM server metadata. -- Mark Stapleton ([EMAIL PROTECTED]) Certified TSM consultant Certified AIX system engineer MCSE
