Question:
I understand that if no keyboard is present on a sparc, it will fall
back to ttya as an i/o console.
Is it possible to have serial console access simultaneously with a
proper keyboad console attached? Even on workstations it would be
useful to have remote console access for emergency situations.
Answer:
My initial thought is yes... but I've never configured it so that
both the serial console and the graphical head were THE console.
Maybe it's easy.. maybe not...
Certainly you can run a getty on the serial line though... so you
can at least log in through it. That, I know you can do.
I would probably opt to have the console on the serial port
if I had a choice. It's just a bit more flexible with regards
to what you can do with it (unless you just can't live without
a fat gui).
If the configured 'input-device' isn't present, then it will fall back
to ttya.
Keyboard attached, yes. Keyboard console, no.
There is only one "console", which is determined by the OBP at boot
time. All boot messages and OBP interaction go there.
You can attach a keyboard and use it on the machine while Solaris is
running for normal user logins, but you cannot use it as a console if
ttya is the console.
