I stand corrected. Although I must point out he did say "new" system :-) : Also, if the tape drive is external and separate, it can be turned off and unplugged : and carried to another machine, used, and returned without powering down the : Unix box. I thought you could do this anyway? I've done it frequently on other OS', and assumed you could do the same under FreeBSD. Can't the scsi(8) command be used to reprobe the bus when a device has been added or removed? The scu command under Ultrix/DUnix can do this, and I think it can be done under HP-UX as well. -- Jeff Aitken jaitken@dimension.net
