How to gain access to RSC

Posted on 2006-06-16

I have a new V490 server. It is preinstalled with Solaris 10. When I first connected to serial management port, it shows 'Please login'. I tried possible default passwords that the vendor provided to me, and none of them worked. Anyone worked with Sun Fire V490 and Solaris 10?  It seems that only the diag light is on in front pannel no matter I put the key in normal or diag mode. It did not move further in booting.

Please help!

If the OBP is 4.15.0 or later, then the keyswitch can be put in the "diag"
position to enable "service mode". Then, the system can be power cycled
or reset remotely to force output to ttya. See document 79449 for more details on

If the OBP is earlier than 4.15.x, then follow the steps below:

     Access the system as root to create a new RSC user. If root can login
     into system remotely then proceed to Step 2.

     If root cannot access system remotely and RSC is currently the active
     console then the only other way to gain access to the system console
     would be through ttya. However, because RSC is configured we would need
     to change the system's output and input devices back to their default
     settings. Setting these defaults can be accomplished by using one of
     the following two methods:

     * Method 1:
         After turning on the power to your system, watch the front panel
         wrench LED for rapid flashing during the boot process. Press the
         front panel Power button twice (with a short, one-second delay
         inbetween presses).

             The above procedure temporarily overrides certain nvram
             parameters to their default settings.
             The original values will be restored after the next
             hardware or software reset.

     * Method 2:
         Remove RSC card.
         By removing the RSC card, the output and input devices will forced
         to ttya. For information on how to remove the RSC card, please  refer
         to the Server Owner's Guide.

         When the system is at the ok prompt, manually set the input-device
         and output-device parameters back to ttya. Once this has been done,
         the RSC card can be re-installed into the system. For  information on
         how to install the RSC card, please refer to the Server Owner's  Guide.

     With both methods, when the console is on ttya, boot the OS and log in
     as root.

     a. Execute the following 3 commands in order to create a new RSC
        user with full permissions:

           /usr/platform/`uname -i`/rsc/rscadm useradd <username>
           /usr/platform/`uname -i`/rsc/rscadm userperm <username> cuar
           /usr/platform/`uname -i`/rsc/rscadm userpassword <username>

        Note: You may need to delete an RSC user if there are already
              4 existing RSC users defined.
     b. Reboot the RSC card.
     c. Log into RSC using the login and password created in Step 2a.
     d. If you used method 1 in step 1 above, you will have to reboot the
        system to allow the RSC card to be used as the console again.
     e. If you used method 2 in step 1 above, then you will have to return
        your input-device and output-device to "rsc-console" to set up the
        console as the RSC card again and reboot.

It is advisable to check that the login created in step 2a works prior to
re-enabling the RSC console.
