I am new in db2 and recently assigned to do backup jobs for db2.My problem is whenever I want to backup the database to the tape,the tape directory is not displayed in the backup options and whenever i click on the browse button and specify the directory name like //test,the name is not exist in the tape and there is nothing being backup to the tape .I'm using dds4 tape media and the drive is properly installed.i don't find any difficulties when using it for sql server. I have no idea why it is so difficult to recognized and backup to that tape.

Do you have any ideas on how to make it recognized the tape and is there any command line for db2 backup in dos..???
