We have not gotten as far as installing Linux for this purpose, but our research indicates that you will indeed need a LAN connection (more specifically, an Ethernet or Token Ring connection) from Linux to the library. Our research also indicates that you will need FCP (Fibre Channel Protocol) connections from Linux to the tape drives. As usual with recent hardware, only the variant of FCP that uses switches is supported; point to point and arbitrated loop connections are not supported. The main sources for these conclusions are the device support Web page for TSM: http://www-3.ibm.com/software/sysmgmt/products/support/IBM_TSM_Supported_Devic es_for_Linux.html#IBM%20Magstar%20Tape%20Products which states that the IBMtape device driver is required, the README page for the driver: ftp://ftp.software.ibm.com/storage/devdrvr/Linux/SLES8/IBMtape_Magstar_zSeries .ReadMe which states that only FCP attachment is supported, and the device driver documentation page: ftp://ftp.software.ibm.com/storage/devdrvr/Doc/ which contains documents stating that FCP is required for tape drive attachment and that Ethernet or Token Ring is required for tape library attachment. One of my co-workers reports seeing the same attachment requirements in Web accessible copies of handouts from IBM presentations to SHARE and other user groups.
