I'm accessing the console by TELNETing to the blade chassis, and connecting to the blade console. I believe this runs at a baud rate of 57600. Because of this I've modified the following files within mfsBSD: > > etc/ttys (from inside mfsroot.gz) > # Serial terminals > ttyu0 "/usr/libexec/getty std.57600" vt100 on secure > ttyu1 "/usr/libexec/getty std.57600" dialup on secure > ttyu2 "/usr/libexec/getty std.57600" vt100 off secure > ttyu3 "/usr/libexec/getty std.57600" vt100 off secure > # Dumb console > dcons "/usr/libexec/getty std.9600" vt100 off secure > > boot/loader.conf > boot_multicons="YES" > boot_serial="YES" > comconsole_speed="57600" > console="comconsole" > > The Java console from the chassis web interface doesn't work on my laptop, but via another server I've been able to grab the attached screenshot. It states: > getty[706]: open /dev/ttyu0: No such file or directory Seems like it doesn't find any uartX devices during boot. Can you boot the box without the console in such a way that you can ssh into it and get a copy of the dmesg? -- John Baldwinhome | help
