If you have not connected the Drive to the system, I normally don't do that while the system is powered, so yes if you are mounting (physically connecting) the drive it would require a reboot. Although I think I have heard that SCSI can be hot connected, I just don't feel comfortable doing it. It does look as though your linux box has the st driver (and loaded it) so you are half way there, granted I am assuming the PowerVault 112 drive is controllable with normal scsi tape commands and drivers, and is on the scsi bus, I have not got mine yet so I can not confirm. try `cat /proc/scsi/scsi` and see if your tape drive is listed. May I suggest you start here: http://www.tldp.org/HOWTO/SCSI-2.4-HOWTO/st.html Although the following is for the Ftape drives it may help you in general, be aware that you will want to access /dev/nst? or /dev/st? (see [1]) instead of /dev/ftape. read the man pages for tar, mt, and possibly cpio, or if you are using a different tape backup software read its documentation. http://www.tldp.org/HOWTO/Ftape-HOWTO-7.html And the following may also be of use to you. http://www.linuxtapecert.org/ http://www.linuxtapecert.org/links.html http://www.tldp.org/HOWTO/SCSI-2.4-HOWTO/index.html [1] http://www.tldp.org/HOWTO/SCSI-2.4-HOWTO/dnames.html -- Todd Denniston Crane Division, Naval Surface Warfare Center (NSWC Crane) Harnessing the Power of Technology for the Warfighter
