Resetting GSP password

Hi (again)

Is there any way of resetting login/password for GSP?

Please, help.

I've tried this stufF:

Accessing Guardian Service Processor
Internal Port
The Guardian Service Processor (GSP) internal port can be used as a
???back door??? to reset security options in case the GSP administrator
password is forgotten, for example. It can also be used in order to
upgrade the GSP firmware from an HP-UX session. The internal port
needs to be configured in order to use it.
1. On the system, the GSP internal port should be /dev/tty1p0.
2. SAM does not configure the GSP internal port.
3. If the device file is not present, it can be created as follows:
#cd/dev
#mknod tty1p0 c 1 0x010000
4. Since this allows unrestricted access to the GSP and bypasses GSP
security features (no user or password required). Make sure to delete
this device file when you have finished using it.
5. The internal port can be accessed via terminal emulators such as cu.
To use cu, you need the follow entries (the entries must be exactly as
shown):
/usr/lib/uucp/Systems needs the following entry:
gspiport Any;5 gspiport,f900 - ????????????\r\d\r\d\r
ogin:-BREAK-ogin:
uucp asswrd: uucp-BREAK-ogin: uucp asswrd: uucp
The spelling looks unusual, but it needs to be exactly as shown.
/usr/lib/uucp/Devices needs the following entry:
gspiport tty1p0 - 9600 direct
6. when all of the configuration is done, you should be able to access the
GSP internal port with the cu command:
cu-1/dev/tty1p0
7. To terminate the cu session, use ???~.??? [return]

But, with this result:

root@grecopr2:/etc/uucp# cu -l /dev/tty1p0
Connected

And anything else...

Any help??

Re: Resetting GSP password

Hi Ruben,

Try this,

//quote//

When the GSP administrative password is forgotten it can be reset by pressing the GSP reset button and responding, within 5 seconds, to the query that appears on the system console. On the L-Class systems access to the button requires removal of the side panel that covers the PCI I/O cards.

With root login the following HP-UX command can be used to reset GSP.

stty +resetGSP
This functions the same as pressing the GSP reset button, response to query on the system console is required.

Note that all user information and passwords are erased.

This command also can be used on PA-8x00 based A-Class and N-Class servers.

//EndQuote//

Hope this helps.

Re: Resetting GSP password

Ruben,
The back-door you used was closed with the GSP firmware version A.01.09 because it was a security hole.
The only way with an up to date firmware version is to reset the GSP and confirm it at the local console
There is no good troubleshooting with bad data

Rachelle, this link has something to do with servers... looks like unix device or something.

Could it possibly be an incorrect link?
