Boot disk HW path

Hi,
I have following :
# lvlnboot -v
Boot Definitions for Volume Group /dev/vg00:
Physical Volumes belonging in Root Volume Group:
/dev/dsk/c1t2d0 (0/0/1/1.2.0) -- Boot Disk
/dev/dsk/c2t2d0 (0/0/2/0.2.0) -- Boot Disk

Then also my ISEE report says I have boot disk on same HW path, i shud purchase new hardware to shift the alternate disk. isnt it something wrong report?
Thanks and rgdz
Prashant

Re: Boot disk HW path

Did you execute dd from c1t2d0 to c2t2d0 ?

# echo "0x2008?4D" | adb /dev/dsk/c1t2d0

# echo "0x2008?4D" | adb /dev/dsk/c2t2d0

Execute the above commands. If the output for the both the disks match, that implies
LVM headers on both the disks are same.

Re: Boot disk HW path

Only one of the field is differing in this:
# echo "0x2008?4D" | adb /dev/dsk/c1t2d0
2008: 157971547 976681765 157971547 976681766

root@crdushp5:/.root

# echo "0x2008?4D" | adb /dev/dsk/c2t2d0
2008: 157971547 978017094 157971547 976681766

What is recommended next?
Thanks and regards

Re: Boot disk HW path

I dont see any problem with this. PVID field should be different.

May be it is referring to the way your mirroring has been setup ? - It would be a good idea to check and confirm the allocation policy (PVG-strict) and if you have /etc/lvmpvg file.

Re: Boot disk HW path

Prashant --

Its possible that its complaining because both of them are off of the 0/0 card although I'm not sure.

Are we sure these are seperate disks or are they alternate links to the same disk ?

Re: Boot disk HW path

They cannot be alternate links to the same disk since the PVID is different. If both the device files refer to the same device then PVID will be same.
