I have a critical problem , that:
i have a VSAT NMS based on SUNspark 20 ,solaris 2.5.1 environment
suddenly vsat system is down , and no disply on the SUN monitor?no thing to do !!!?
the light emiting diode is green on SUNspark?
SO please could you guide me to analys the problem and solve it ?/
I'll bite.
Since you mentioned that the normal function of the system seems to have stopped working, have you powered it down, then tried to boot it back up?
Is there a Sun keyboard and mouse directly connected?
No keyboard == no output to a monitor.
Next, if the VSIMMs have failed, the onboard video circuitry stops working.That would mean shutting down and repairing/replacing components.
Can you ping the SS20?
Can you telnet to the SS20?
If you can connect via telnet, then go in and review the system logs.
If the SS20 is not reachable by telnet then shut it down and use the information in the top two sticky posts in this Workstation Forum to establish a connection from another computer. Then your investigation can begin.
Thanks alotBills ;
I proceeded with your steps but :
i can not access ss20 with telnet
no response form ping
I would like to tell that ;
after power-on the ss20 , the key board makes tone as well as CAPS LOCK KEY flashes , and eventually the SCROLL LOCK KEY IS ON (green)
but no any out put disply ?
expect and wait to hearing from you an answer for this case ,,,please
Regards
If you cannot connect via telnet, then it may not be fully booted to multiuser mode. (Probably waiting for some maintenance, such as having a filesystem repaired.)
The keyboard lights 'seem' to be showing you normal function, so I think it is passing the very first part of POST.
Unless you can establish a TIP connection as described in those sticky posts, you will never be able to investigate any deeper.That sort of a connection will let you see the boot process on the screen of another computer.If you have never done this, then it is time that you taught yourself.It is a standard diagnosis method.
