n4000 gsp update

Hi there, I have searched all previous threads but have been unable to find the answer to my problem. I am trying to upgrade the f/w on my gsp from a01.06 to a01.12, but when i log in to the gsp there is no "lc" command available. I have upgraded many L1000/2000 systems successfully by pressing reset on the gsp and resetting the passwords, which then gives me administrator access and the "lc" command. I have tried to issue a reset from the unix comand line but this still does not give administrator menus. Am I missing a trick somewhere, or is there a different way of getting the "lc" command on a N4000 gsp?
thanks in advance

Re: n4000 gsp update

Hi, if i remember correctly there is a gsp reset switch at the back on the core i/o board, on the right hand side. Press this and then get to the console quickly to confirm you want to reset the passwords.

Re: n4000 gsp update

Thanks for that Andy, I did that and did not get the option to reset the passwords at all, so where now

Re: n4000 gsp update

are you connected directly to the back of the system on a local serial console port?

I'm pretty sure you need to be to do the reset

Re: n4000 gsp update

Yes, I am directly connected, press the reset button, the light comes on and no message appears on the screen. I then have to do a Ctrl+B to go back in and I am still in the operator screen

Re: n4000 gsp update

Be on the console, connected to GSP when doing the manual GSP reset.

The password reset prompt is only displayed for 10 seconds or so, be there to catch it right away.

Re: n4000 gsp update

Hi Scot thanks for that, but it just does not appear at all, I am stood in front of the screen as soon as I hit the button and nothing appears at all

Re: n4000 gsp update

Re: n4000 gsp update

Hmm, you should at least see some msgs displayed about the GSP reset.

Re: n4000 gsp update

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.

Re: n4000 gsp update

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"

Re: n4000 gsp update

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?

Re: n4000 gsp update

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
