Boot in single-user mode? Detailed
instructions might be more reliable if anyone
other than you knew something about the
system (OS, hardware, console. ...)

How are you entering into system through console or remote session using ssh or telnet?

In this case, you take system into single user mode using following steps:

You can login to MP...type cm, select rs--->your partition no and press y
This will restart the partition, now you can stop at BCV by pressing any key, (it asks for that) and type bo pri, (to boot with primary path)
when asked if you want to interact with ISL(Initial System Loader), select Y
You will get ISL prompt
interact with ISL (Y/N): Y (type y)
ISL>
Type hpux -is
This will land you to # prompt
#

Now you can change password here using passwd command.

Boot the system in single user mode. you will get the below prompt

You will get ISL prompt
interact with ISL (Y/N): Y (type y)
ISL>
Type hpux -is
This will land you to # this prompt

then mount the /usr,/var,/temp

after mounting it use the
#modprpw -k root

Hi Jackizam,

FOR PA Servers.

1--> reboot
2--> stop the boot sequence and go to the isl prompt.
3--> run hpux -is
4--> reset the password.

FOR IA64 Servers.

1--> Interupt the boot sequence at EFI boot
2--> Choose to boot from Primary boot path
3--> boot vmunix --> interupt.
4--> at the EFI prompt type
EFI> boot vmunix -is

you will get # prompt.

# passwd root
Enter new password:
Confirm:

#init 3 <---- boot into run level 3

OR

# shutdown -r -y 0 <---reboot the machine

Asif Sharif

Hi

FOR PA Servers.

Firt you have to reboot the server through mp console mp---cm---rs--yes
Then then the server will reboot ,

Whenever the server will reach the boot sequence prompt then select the isl prompt (for PA servers), and run the below command.

hpux -is

For IA 64 servers select the EFI shell prompt and run the belo command

boot vmunix -is

you will get # prompt.

# passwd root
Enter new password:
Confirm:

After these activities you have to reboot the server by the below command

# shutdown -r -y 0

Best Regards

You got a question with almost no useful
information. You expect the person who asked
it to explain the solution in greater detail?
Seems to me unrealistic.

Hi,
My solution is:
1--> Interupt the boot sequence at EFI boot
2--> Choose to boot from Primary boot path
3--> boot vmunix --> interupt.
4--> at the HPUX prompt type
HPUX> boot vmunix -is

you will get # prompt.

# passwd root
Enter new password:
