Hi,

use just

setboot

You'll see the primary path and the alternate path (which is the mirrored disk).

HTH.

Best regards,
Fabio

# setboot
Primary bootpath : 0/8/0/0.3.0
Alternate bootpath : 1/4/0/0.3.0

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

This will tell you which is your primary and which is your secondary disk

Hi Ajin,

Boot disks configured shown by:
# setboot
# lvlnboot -v

To find which disk the system is booted from currently:

# more /var/adm/syslog/syslog.log | grep -i boot

Nov 30 12:35:43 xxxxxx vmunix: Boot device's HP-UX HW path is: 0/1/1/0.1.0

So you will get the HW path of current disk.

Regds..

#setboot
would tell you which is primary disk and which is secondary and
#lvlnboot -v
would tell you which disk are boot disks so as to decide which disks you need to put in setboot.

Hello Ajin, How are you?

One liner From my old notes:
echo "boot_string/S" | adb -k /stand/vmunix /dev/kmem

Cheers!!

hi

u can use

#setboot

# dmesg | grep -i boot

this will show the last boot disk in which the system is booted..

if u have both primary and secondary disk

u can use this

# echo "bootdev/X"|adb -n /stand/vmunix/dev/kmem

if u have IR volume

then

#echo "boot_string/S" | adb /stand/vmunix/dev/mem

compare the both output value bt

#ll /dev/dsk

Hi

You boot off of the alt, look at setboot, see both the pri and alt listed in the output and you can't make a distinction. 'setboot' lists three possiblitiles including the cdrom.

To find what you are currently boot off of you have to query the kernel with this command:

echo "bootdev/X" | adb -o /stand/vmunix /dev/kmem

...is correct choice for Ia64 and,

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

...is the correct choice for Pa-risc.
