Thank you to everyone who answered my request for the 6800 Password unlock
procedure.
Although I received many different emails, they all said basically the same
thing, that is as follows.
SUN PROCEDURE FOR RESTING SC PASSWORD ON 4800/6800
How do we reset the platform administrator's password if it is lost or
forgotten
?
Resolution
If the platform administrator's password is lost, the following procedure
can be
used to clear the password.
1. Reboot the System Controller (SC). You won't be able to do this by
logging
into the platform shell. You'll need to hit the reset button on the SC to
do
this.
2. The normal sequence of a System Controller rebooting is for SCPOST to
run,
then ScApp. You'll need to wait for ScApp to start loading, then hit
Control-A
to spawn a
vxWorks shell. SCPOST is done running when you see the message 'POST
Complete'.
At this point, ScApp will begin to load. When you see the copyright
message
'Copyright
2001 Sun Microsystems, Inc. All rights reserved.', Hit CONTROL-A. You
should see
the following:
Task not found
spawning new shell.
->
This last line is the vxWorks prompt. Keep in mind, that ScApp will still
continue to load all the way to the point of giving you the menu to enter
the
platform/domain shells. To
make it less confusing, wait for the ScApp menu to display on your screen,
then
hit return. You should see the vxWorks prompt -> again.
3. Make a note of the current boot flags settings. This will be used to
restore
the boot flags to the original value.
-> getBootFlags()
value = 48 = 0xC = '0'
* Save the 0x number for # 7 below.
4. Change the boot flags to disable autoboot.
-> setBootFlags (0x10)
5. Reboot the System Controller. Once reset, it will stop at the ->
prompt.
Use CONTROL-X or the reboot command to do this.
6. Enter the following commands at the -> prompt.
-> kernelTimeSlice 5
-> javaConfig
-> javaClassPathSet "/sc/flash/lib/scapp.jar:/sc/flash/lib/jdmkrt.jar"
-> javaLoadLibraryPathSet "/sc/flash"
-> java "-Djava.compiler=NONE -Dline.separator=\r\n
sun.serengeti.cli.Password"
Wait for the following System Controller messages to display. Your prompt
will
come back right away, but it'll take about 10 seconds for these messages
to show
up:
Clearing SC Platform password...
Done. Reboot System Controller.
7. After the above messages are displayed, restore the bootflags to the
original
value using the setBootFlags() command.
-> setBootFlags (0xC)
* Use the value returned from #3 above.
8. Reboot the System Controller using CONTROL-X or the reboot command.
Once
rebooted, the platform administrator's password will be cleared.
This procedure works with firmware version 5.11.3 and higher.
Thanks Again
Glenn May
