setboot question

Luke Bell — Tue, 30 Nov 2004 10:16:38 GMT

hi

I booted one of my hp L Class servers last night only to find that it automatically interrupted the boot up and just sat at the boot prompt.

I have been looking and it seems that I can change this setting using

/usr/sbin/setboot -b off

Is this correct has any one used this before?

I might be able to try to turn it on on a test server then turn it off but I don’t want to try it until I understand more what it does the man page wasn’t all that clear.

If this isn’t the way of stopping the box interrupting boot up what is?

Actually, I think you want to set autoboot on:

setboot -b on

You should probably set autosearch on, too.

Then check:
Just type setboot
the output should look like:
Primary bootpath : 0/0/1/1.2.0
Alternate bootpath : 0/0/2/0.2.0

Autoboot is ON (enabled)
Autosearch is ON (enabled)

All the best

This out of th man pages:
AutoBoot AutoSearch Boot Action
_______________________________________________________________________
off off Go to the BCH and prompt the user.
on off Attempt the primary path; on failure
go to BCH.
on on Attempt the primary path; on failure
try next path.
off on Skip the primary path and try alternate path.
If the alternate paths are not configured to
boot or fail, go to BCH.

ive just tried this autoboot off and on on the test box and thanks it works

with autosearch on though it seems that when it interupts the boot process it automatically searches for bootable devices.

this is fine on my test box as ive only got 4 devices but on my production box theres 30 or so so it could take a very long time to search?

As Victor pointed out, the action taken when autoboot and autosearch is one is to attempt the primary path and automatically search if that primary path fails. In normal circumstances the extra 30 devices would not make a difference.
