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.
