Actually i am too new to netbackup.So the guy who was handling before told me that i have to remove some tapes out the 15 before .And after that i can only add new tapes.So i got it wrong and he also told me the wrong procedure .And i also followed the same as i was not having time to go through the doc's.Now when i go throught the docs i found that he told me the wrong procedure .Actually he was not using to choose the option on (Empty media access port ) I was also following the same and Now i looked the docs and got the right procedure and now i am able to get the tapes ...:)
