WANT TO GET DATA BACKUP ON TAPE FROM SITE "A" AND RESTORE IT FROM SITE "B"

Previously we got site "A" node pool data backupsets on tape cartridges from TSM and easily restored it  on site "B"  after create a same node pool like site “A” and then creates table of content and restored it. Now we are using Commvault and want to restore on tape backup data from site "A" to site "B".  Could you tell me how can we do via Commvault?
