Urgent:L2000 GSP - console write access failed

Hi all,
I have a task to rebuild this L2000 server.

I don't have root password
I don't have LAN IP address

I only have GSP IP address and Login/Password

I knew the system was in trusted system.. and has ignite disk available.

When I tried to reset root password using single mode, it still asked me old password.

Then I don't know what happen it hangs... when I tried to reconnect to the GSP. I got this message, "[Request for console write access failed!]". That is everytime I press Ctrl-E c f.

Please see attachment for screen dump.

How am I able to regain the access for GSP?

And how am I able to reset root password?

Please help me... Thank you...

Are you sure about the new IP settings (gateway correct)?

You need to reset the GSP to make them valid:

...
-> Settings have been updated.
-> Reset the GSP for LAN configuration to take effect.
-> Use the R option of the XD command to reset the GSP.


In your case, the most easy way to do this is pulling the power plugs.

Hope this helps!
Regards
Torsten.

It appears that the current state of the GSP will not allow access. As mentioned, push the GSP reset button and try again. If that doesn't work, a reboot will not help. The GSP runs all the time, even when the CPU has been powered off. You need to remove the power cords for a minute, then plug them for a GSP reset. Once you get the GSP working, you may need to patch the code if the version is old.

Thank you... after reset GSP, now I have gain write access.

How do I reset my root password in a trusted system without reinstall the whole server?

You need to get into single user mode, if you haven't established a password for that too.

Re: Urgent:L2000 GSP - console write access failed

1. Boot the system in to single user mode.

2. Mount /usr file systems.
# mount /usr

Note: The file system might need file system check (fsck) before mounting.

3. Use the below command

# /usr/sam/lbin/usermod.sam -F -p "" root


4. Change the root account password.
# passwd root

5. Boot the system in to multi user mode.
