I have to add new tape drives to our IBM 3494 library connected to TSM server 184.108.40.206 on AIX 5.3. We already have 10 tape drives that are running. I have to add another 4 tape drives. I know that once installation and zoning is done. I can add the tape drives to TSM. I need a step by step procedure for adding the tape drives in TSM and making it visible for the tape backups. Please help me in this.
