hi again, the only other way i could think of is to configure the gsp through hpux if thats possible. never tried it but theres lots of threads regarding this
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]

from the 7400 hardware manual

then if you run the command

# stty +resetGSP < /dev/GSPdiag1

from the console, a message like

"press 'p' within 5 sec to reset all user accounts"

should come up.

failing that, possibly faulty gsp/core io board.

Hi Andrew, thanks for that explicit answer, however while we have been corresponding my salesman has sold both discs from my system so now I have no unix to try. While I had them I did do the stty +reset command but that didn't prove any help. I think that I will print off your reply and wait until I can get a disc and reload unix. There is one more thing I was wondering ....... If I took the battery from the GSP might that clear the passwords or would it do more damage and leave the system completely "kerry packered"
cheers

hi, it might work, i've read that some people have done it or just pushed a piece of paper between the contacts for a minute or so to clear it. This apparently will clear all the config?

Hi Andrew, have "papered" the battery for 5 minutes and hey presto..... can get into the system as administrator to update the f/w.
Thanks for all your patience, will now close the thread, but I am still none the wiser as to why the reset did not work properly
cheers
