hp ux

Hi,

I was trying to find out what this command does and why it would not run.

hpux -vm

I have someone asking me but I am more hardware than software.

Thank you
Jon

Shalom Jon,

You might try giving us a model number, an OS and some context.

I will take a leap and guess you are at the ISL or EFI prompt.

hpux -is
#single user mode
hpux -lm
#logical volume maintenance mode

I've never used the -vm switch and do not even know if its valid.

Have you tried "man hpux"?

" hpux(1M) hpux(1M)

NAME
hpux - HP-UX bootstrap"

Hi,

Ok it looks like it is for booting the machine in maintenance mode/single user mode. Is there a reason this command would not work?

Could it be a corrupt OS?

thanks
Jon

As Pete said...it's all there in the manpage

You must be "root" to run these...

-vm Boot the system in VxVm maint mode, etc..

-lm Boot the system in LVM maint mode, etc..

You use this command when you interupt the boot process. Both hpux -lm and hpux -vm will put you initiate single user mode.

If you are unfamiliar with these commands, you may want to be sure to have someone handy (i.e. HPUX Admin)with you when you try them.

Regards,
Rita

Just to clarify, in case there's a misunderstanding:

"hpux -vm" and other similar commands are not meant to be entered to the shell prompt while the OS is running: the shell command "hpux" does not exist.

These commands are for the ISL> boot prompt of the PA-RISC hardware.

The standard procedure on server systems is:

- Power on the system. Wait for the self-tests to complete, then press any key on the console to interrupt the boot sequence. The system will display the PDC> prompt.

- Type "boot pri" (or "boot alt" or whatever)
to boot from the system disk.

- The system should ask something like "Interact with IPL (Y/N)?" Answer Y.

- You will now see the ISL> prompt. Here you can use the "hpux [options]" -style commands, as documented in "man hpux".

Actually you must have access to the console and root isn't needed since you haven't logged in yet.

Thanks for your help. It seems the OS was corrupted somehow and they had to reload the OS.

Thanks
