Hi Bill Just check out the readme-files that comes with the patch/maintenance package. It clearly states that Tivoli recommends connecting the tape drives on separate adapters from the disk.
>From the readme-file of the TSM StorageAgent for SUN v5.2.1.3 (ftp://ftp.software.ibm.com/storage/tivoli-storage-management/patches/storage-agent/5.2.1.3/TSMSTA5213_SUN.README): ********************************************************************************* * Host Bus Adapter recommendation * ********************************************************************************* It is highly recommended that Tape Drives and Tape Libraries be connected to the system on their own host bus adapter and not share with other devices types (DISK, CDROM, etc.).

They don't think that mixing the 2 will be a performance issue. I remember a couple years ago this was an issue of data corruption, but that has been addresses. Can someone point me to any whitepapers or documentation explaining why they should spend a couple more $'s and get an additional adapter for those server they want to do LANfree backups on?
