mirrored boot drive 1

[cndcadams]

I was wondering if there is a command in the OS that will tell me which device of my mirrored boot drives the system was booted from.

Thanks

do you have an ILO/MP card within your host? I found an entry in ConsoleLog
Boot device's HP-UX HW path is: 0/1/1/0.1.0

just doublechecked: If you are lucky it is still in the dmesg

[daFranze]

yes, I'm a nitpicker ;-) : setboot -v displays the value of a variable, which might have changed since last boot

Here you are ...

echo bootdev/X | adb /stand/vmunix /dev/kmem |\
awk '/[0-9i]/{print "Boot disk:/dev/dsk/c"substr($2,4,1)"t"substr($2,5,1)"d0"}'

Example ...

root@xxx# echo bootdev/X | adb /stand/vmunix /dev/kmem |\
> awk '/[0-9i]/{print "Boot disk:/dev/dsk/c"substr($2,4,1)"t"substr($2,5,1)"d0"}'
Boot disk:/dev/dsk/c1t6d0

Gentlemen;

Thanks for the responses. setboot command I was aware of but it shows primary and alternate which I was not sure if it would change if someone decided to boot the alternate drive. I figured it would still show the same paths for primary and alternate no matter which one you booted(I will have to run a test to see what happens.


daFranze thanks for your input, I will keep that in mind.

Martin999 your response gains a star for effort. I ran the command it is what I was looking for. I will have to document that as I know I will not remember the syntax.

Thanks again

Glad it was of help, yep, got it documented as I can't remember it either .... thanks for the star

Martin999:
works an PA-RISC, but on itanium systems bootdev/X does not work. Any idea what to change?

 

[Martin999]

Hmm, I'll look into it, might have to bare with me ..

 

[Martin999]

Try ...

echo bootdev/X | adb /stand/vmunix /dev/kmem (and process the output - leading 0x at 11.23)

or:

echo boot_string/S | adb /stand/vmunix /dev/kmem

Unfortunately, just discovered we haven't actually got any Itanium systems yet ... so this is untested.
Let me know how you get on.

Thanks,

Martin

Hi Martin,
echo bootdev/X | adb /stand/vmunix /dev/kmem
gives the error message
adb: warning: Unrecognized format character - 'X'.

echo boot_string/S | adb /stand/vmunix /dev/kmem
says
adb: warning: Unrecognized format character - 'S'.

I wonder if there is a document out there explaining the differences between adb on pa-risc and itanium systems.
Thanks for your help,
stefan

rtfm you could say: when i use the -o flag for adb it works in backward compatibility mode and works just as on any pa-risc system:

echo bootdev/X | adb -o /stand/vmunix /dev/kmem
bootdev:
bootdev: 0x1f021002

Thanks swolf ... yep rtfm )
