Read LIF Header

PVR — Mon, 05 May 2008 07:33:36 GMT

Hi Champs

I use the following command to read PVRA of a disk in HP-UX 11.11

echo "0x2008?4D" | adb /dev/dsk/c5t1d0

This shall give me CPU ID, PV ID etc. from the LVM header of the disk.

But when I try the same command in 11.23 and 11.31, it didn't give me anything. It simple hangs....Is there any difference in the LVM structure in 11.23 and 11.31 ?

Thanks in advance :)

HI:

Add the backward compatability switch to 'adb' on 11.23 or later:

# echo "0x2008?4D" | adb -o /dev/dsk/c5t1d0

Regards!

Instead of using confusing adb, you should use xd:
# xd -tx4 -j 0x2008 -N 16 /dev/dsk/c5t1d0
