What is the meaning of tape minor numbers (rst interface) in FreeBSD 2.0-RELEASE? I find there are rst0, rst0.0, rst0.1, rst0.2, rst0.3 and nrst* (norewinding?), erst* (what're they?), ct0ctl* (again, what're they?) I've attached an Exabyte EX8200 tape drive to the system (a NCR53c810 SCSI bus), but I can only read/write to rst0.2, but not other rst0*, why? Which minor number should I use for the command 'mt'? I want to do rewind, offline, erase, etc. stuff. But whenever I issued mt status command, the OS complaints with something like: 7: unknown tape type How to cope with it? I also tried to attach a Tandberg 3600 QIC tape drive to the SCSI bus, the bootup message identified it as "a known rouge", what did that mean? But the mt command also fails on the Tandberg! Can anyone enlighten me? Thanks in advance. Stephen Wong.
