Hi,

After you have replied "Y" or "yes" on Interact with IPL. This will be your command line to go to single user mode "hpux -is".

Or you can drop down to single user from a running system with "shutdown -y 0".

One important difference in dropping down to single user is that some filesystems in the root VG will remain mounted which do not get automatically mounted when going to single user mode from boot.

Hi Joshua,

An other utility available as tell you Alan is that you maintain open your telnet terminal to work and you don't need to use the console.

Justo.

Hi joshua,
If you are in multi user mode, you can execute 'init 1' (be sure to inform all your users)
or restart your machine and interrupt the boot process, reply 'Y' to interact with IPL. and execute 'hpux -is' on ISL prompt

Just for your information, as the specific answer has already been given:

This is documented in the hpux(1M) manual page, i.e. "man hpux".

The boot(1M) manual page ("man boot") points to the relevant manual pages, pdc(1M), isl(1M) and hpux(1M).

What often helps in cases like this is trying the "man -k" command with a suitable keyword.

For example in this case "man -k boot" would have pointed you to the boot(1M) manual page. (However "single" and "user" would have given no_suitable/too_many pages, so your mileage may vary.)
