Booting HP-UX into single user mode?

[D K_1]

Can you do the Solaris equivalent of:
ok boot cdrom -s

Thanks!

Hi:

The HP-UX equivalent is: ISL>hpux -iS

...JRF...

[D K_1]

This will boot into single user mode off of a cdrom?


Thanks!

Hi DK

It depends on the servers you have - however, when you are prompted to go into ISL, press enter to enter ISL and type search this would search and return all the bootable path names of all the bootable devices, you then have to use the boot command to boot (with the hardware path for the CD) to from the CD

ISL> search
ISL> b P1 (or something like that)
take a look at the manual - HPUX System Administration Tasks http://docs.hp.com/hpux/pdf/B2355-90672.pdf
for the section on starting and stopping hpux

Good luck.

To boot off of the CDROM you need to interrupt the boot sequence by hitting any key when prompted (default 10 second delay). Then specify the SSI path of the CDROM after the boot (bo) command.

"bo 10/12/5.2.0" for instance. If you don't know the path, then a search for bootable media should show it: "sea install"

If you simply want to enter single user mode, though, you so not need the CDROM. Simply interupt the boot, tell it to boot off of your root default root volume, "bo", then answer "y" when it asks if you want to interact with IPL/ISL. When the IPL prompt is displayed, enter "hpux -is".

Hi David,

Perhaps you can explain a little more about what this boot mode does on Solaris? Does it allow you to boot into a fully functioning OS, or is it some limited capability OS, such as would be used for recovery operations?

For what it's worth, I'm only familiar with the recovery type of boot on HP-UX, and even then, you'd have to boot a special CD, meant specifically for recovery operations (i.e. I don't believe you can boot into single-user mode from the Install/Core OS media, except to perform recovery operations). This type boot is not the same as booting single-user mode from the hard drive.
