Ben, use the *st or *stc device. There is a section on how to configure 3583/Solaris/TSM in the Using IBM LTO Ultrium with Open Systems redbook SG24-6502, see page 158. You will find this redbook very helpful.

Dist Stor Manager" <[EMAIL PROTECTED] .EDU> 02/06/2002 03:15 PM Please respond to "ADSM: Dist Stor Manager" We are hooking a new IBM 3583 tape library up to a Solaris host to be a remote site TSM server. The Ultrium drives have various /dev/?st... devices through which we can access them. The no-brainer was to use the driver that tells the drive to compress the data, but I'm not sure between these 2 options: /dev/rmt/*stc <- compression and "Rewind on Close" /dev/rmt/*stcn <- compression but "No Rewind on Close" I can't find anything in the TSM or library documents on which to use. Does TSM get confused if a tape were to be mounted and it was not at the beginning? Kind of seems like we would reduce tape and drive wear by using the "no rewind" device drives, and writes might happen quicker it the tape is not rewound... Any suggestions would be helpful. (the listserv archive site is currently inaccessible.) Thanks, Ben Micron Technology Inc.
