How do you determine the current boot path/device

Correct. The mirror is only written during normal operation. All reads will come from the primary.

As far as Itanium, the above procedure mentioned about tracking down the minor number from the adb...bootdev result. As seen in the bootinfo script above, you get the adb results, extract the device number (something like 0x1000004) digits, then search for a match of the minor number in the disk devicefiles.

Not straightforward, but everything about booting in Itanium is convoluted...

[Torsten.]

Usually this can be found in syslog and dmesg (if still not overwritten):



Boot device's HP-UX HW path is: 0/7/1/0/4/0.0.0

[Torsten.]

Note: the path in 11.31 is in agile format, e.g.


Boot device's HP-UX HW path is: 0.0.c.1.0.4.0.5000112345678123.4001000000000000

Bill -
I tried to attached script and I'm getting usage errors.
Here is the output:
bootstring using adb:
Last booted using ioscan: /dev/disk/ is not a special file
ioscan: /dev/disk/ is not a special file
0xffffffff ( or )

lvlnboot -v:

[Bill Hassell]

Looks like you need to update your bootable disks. lvlnboot -v is not reporting anything and several parts of the script depend on having valid boot values.

[Bill Hassell]

Also looks like setboot is empty, which means your system won't reboot without interaction.
