Primary Boot Disk you can find out by using:-

On HPUx 11.23

# echo "bootdev/x"|adb -n /stand/vmunix /dev/kmem
bootdev:
0x1f020002
# ll /dev/dsk
total 0
brw-r----- 1 bin sys 31 0x020000 Oct 8 2004 c2t0d0

brw-r----- 1 bin sys 31 0x020002 Oct 8 2004 c2t0d0s2------------->>

brw-r----- 1 bin sys 31 0x034000 Oct 13 2004 c3t4d0
#

On PA-RISC

# echo "boot_string/S" |adb /stand/vmunix /dev/mem
boot_string:
boot_string: disk(0/0/1/1.15.0.0.0.0.0;0)/stand/vmunix
#ioscan -fnH 0/0/1/1.15.0.0.0.0.0

# dmesg|grep -i boot
Boot device's HP-UX HW path is: 0/1/1/0.1.0

# ioscan -fnH 0/1/1/0.1.0
Class I H/W Path Driver S/W State H/W Type Description
=====================================================================
disk 2 0/1/1/0.1.0 sdisk CLAIMED DEVICE HP 146 GMAP3147NC
/dev/dsk/c2t1d0 /dev/rdsk/c2t1d0
/dev/dsk/c2t1d0s1 /dev/rdsk/c2t1d0s1
/dev/dsk/c2t1d0s2 /dev/rdsk/c2t1d0s2
/dev/dsk/c2t1d0s3 /dev/rdsk/c2t1d0s3

Hi,

For Finding the Physical Boot Disk & Seconday Boot Disk.

Check with setboot & lifls -l command.

root # setboot
Primary bootpath : 0/1/1/0.1.0
Alternate bootpath : 0/1/1/1.2.0

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

Then on the Primary bootpath & alternate boot path to check boot related information with the help of disk address.

root # lifls -l /dev/rdsk/c2t1d0

please use below command to findout booted root disk
For ITANIUM,
echo "bootdev/x" | adb -n /stand/vmunix /dev/kmem

from the output
# ll /dev/dsk/* | grep -i

For PA-RISC
echo "boot_string/S" | adb -n /stand/vmunix /dev/kmem

You can get configured primary & secondary disk in the system by setboot -v command

HI guys,

there would be corruption in my previouse post

please see the original below

For ITANIUM,
echo "bootdev/x" | adb -n /stand/vmunix /dev/kmem

from the output
# ll /dev/dsk/* | grep -i

For PA-RISC
echo "boot_string/S" | adb /stand/vmunix /dev/kmem

You can get configured primary & secondary disk in the system by setboot -v command

Hi,

try "lvlnboot -v" to get the Physicla Disk Path which the system is booted up with.

also you can use setboot, but this might not guarentee you of the disk you are booted with.

thanks
Shi
