Changing HW path of the system volumes

[Prema Krcmar]

Hallo,

I failed one change. It was about moving rx8620 cells ..
When cell was moved to new location (and different cell position) system did not boot because HW path of internal system drives has changed (I expected that) so I booted into maintenance mode and tried to persuade vg00 that drives is still there but with different path (I used 'vgcfgrestore -o' command) ... and I was unsuccessful. Is there any another way ? Does vgcfgrestore works on vg00 ?

Also when I was fixing this with ignite - ignite has same issue, system drives are not present - and was trying to restore image on SAN drives instead. I used advance menu, I selected only internal drives, but it scan hw on startup of the menu and then was ignoring what I selected (at least for system drives). I finally fixed it by manual editing of configuration file .. but all this took a lot of time ..
Just one note - it was on remote destination and I had no chance to have FC cables unpluged.

HW and OS:
ia64 hp server rx8620
HP-UX B.11.23 ia64

Thanks ahead for answers and ideas ..

As for the first part and this question:

and I was unsuccessful. Is there any another way ?

What you need no to do if your HDW path to your vg00 has changed is:

go into -lm
export vg00
import vg00 with map
lvlnboot -v -R vg00
setboot -p NEWHDWpath

And it should work with no problems.

And the other way, with ignite it should work perfec. just restore your image to your internal hard drives.

What exactly did you change (old and new position of the cell; what cells are in the nPar, etc.)?

Internal disks are "hard wired", so h/w path remains.

Shalom,

Manually boot the system at the EFI prompt.

lvlnboot -r /dev/vg00/lvol3 # root fs /
lvlnboot -s /dev/vg00/lvol2 #swap
lvlnboot -d /dev/vg00/lvol2 #swap/dump
lvlnboot -b /dev/vg00/lvol1
lvlnboot -R
lvlnboot -v
setboot

setboot -a 52.1.0 # second disk

Should permit you to re-set the boot path.

Torsten:

It was in remote location (few hundred miles) .. and I was not involved in planning. Base of this request was consolidation of CPUs with same speed into the same cabinet.
I guess, that just board with CPU and memory plus hard drives was moved. MAC and WWN were same.
