seria console on ultra 60 solaris

Hi!!
I have a ultra 60 running solaris  9 fully installed. It has graphic card on it to. It used to operate as a database server before with monitor and keyboard attached.

Currently, due to oversize SUN monitor, I decided to take it off as well as the keyboard and begin to use serial console. My laptop doesn't have serial port, therefore, i use serial-usb converter.

1. use hyperterminal
2. set to use COM4
bit/second = 9600
data bits = 8
parity = none
stop bits = 1
flow control = none

I connected to the ultra60 and turned it on, had my laptop's hyperterminal connected via COM4.
However, there is nothing showed off on the screen.

Am I missing something? Could it be he SUN's video card?

thanks so much!

Hi,

After disconnecting the console/keyboard/mouse from the server, did you reboot the machine?

Hi,

Normally, once you disconnect the monitor/keyboard/mouse and power on the m/c, the login process will be running on the serial port.

Possible reasons, could be

- The wrong specification of port on the laptop (COM4)
- The wrong / faulty cable
- Faulty serial port on the m/c

thanks!
what cable should I get?
I used 2 cables connected together
1. 25 pin --> 9 pin
2. 9 female --> 9 male

i assume it would work since the cable perfectly fit into the 25-pin port of the Ultra.
They said i would need a null modem cable. Is it equivalent to serial one? one more thing though, is it possible for me to install solaris from console?

thanks so much

Hi,

- Normally Sun will ship a console (serial) cable along with the m/c.

Some useful links for cables and pin assignment.

http://www.lammertbies.nl/comm/cable/RS-232.html
http://www.sunhelp.org/unix-serial-port-resources/serial-pinouts/

- Regarding installing from the console (serial), yes you can.

thanks! Look like that the cable i have been using is not quite correct though.
Just one thing to make sure ;) : the console should work while the station has graphic card installed right?

Hi,

If you do not connect the keyboard/mouse to the m/c while turning it on, the m/c will make the serial port the console and you can see the ok prompt, etc. and when you boot OS you will get login screen, but this will be character based will use command line.

a) If no keyboard is connected, console will be serial port A
    If you still have the option to run with monitor, check if this has not been
    re-programmed in NVRAM. You should either have (default):
      # eeprom | grep put
      input-device=keyboard
      output-device=screen
    or (explicit)
      # eeprom | grep put
      input-device=ttya
      output-device=ttya
    You can change with
      # eeprom "input-device=ttya"    
b) Some USB-to-serial converters are NOT working correctly :-(
    Especially if you use a converter that also requires some driver software
    for windows, it's very likely that it will not work as it should.

Thanks!!
The bad thing is that my laptop does not have serial port. I just found out a DB9-RJ45 converter that i used to configured PANSAT. Will that work as well?
(i'm trying to connect here)

thanks!!

Hanno P.S.IT Consultant and Infrastructure ArchitectCommented:
I don't know the serial port pinout for PANSAT :-(

Unfortunately, many manufactuers use different pinouts for their ports -- that's why
many ship serial cables and/or adapters with it.
Also, pinout may be DTE or DCE ...

I just received the cable. will try it out.
dump question: isn't that Sun supposedly to direct everything to console when no monitor represents. Why we have to set NVRAM?
thanks!

well..it works great!! I finally can look at the console which is much better coz I don't have to carry the big a$$ sun monitor around.

IN addition, I have one database solaris server is running. Can i just safely plug in the cable and look at the console?
thanks so mcuh!

Hi,

Be careful if you are going to use laptop to connect to the serial port. When you start the hyper terminal be careful some times when you stop the hyper terminal window it cause the sun server to go to ok prompt.

I do not recall how to avoid it, but I think you remove the cable then stop the hyper terminal.

I log out first, then disconnect the terminal, then unplug the cable.
Sound ok?

Hi,

Before you close the hyper terminal unplug the cable.

Hi,

Setting the Key to the "Lock" icon will prevent the stop signal from halting you machine.

If you face the situation and find your m/c in the ok prompt due to this problem just type go and enter and the server resumes (do not give boot command, just go command).
