Move a root disk to another server?

Fredric Vådegård — Tue, 25 Oct 2005 07:25:43 GMT

Is it possible to move a root disk (HP-UX 11.00, L2000) to another server with similar HW?
If yes, what steps do I need to perform?

Thanks!

hi,
the HW must be the same...
the HW path of the device must be the same...

similar is not sufficient to be sure that the system boot

YES.

We do this all the time.

1. install disk on new server
2. interrupt at BCH
3. SEA to ascertain your disk HW path
4. Boot that HW path
BCH> boot x/y/z/p.q.h ...
5. Yes to interaction with ISL
6. ISL > boot -lm
7. ioscan;insf -e
8. note new cXtYdZ of boot disk
9. Generate vg map of vg00:
/usr/sbin/vgexport -s -p -m ./vg00.map vg00
10. vgexport vg00
11. mkdir /dev/vg00
12. mknod /dev/vg00/group c 64 0x000000
13. vgimport -v -s -m ./vg00.map /dev/vg00
14. Now fix lvlnbot:

vgchange -a y /dev/vg00
lvrmboot -r /dev/vg00
lvlnboot -r /dev/vg00/root or lvol1
lvlnboot -b /dev/vg00/stand or lvol0
lvlnboot -d /dev/vg00/swap or lvol2
lvlnboot -s /dev/vg00/swap or lvol2

lvlnboot -R
sync
sync
reboot

That's it...

In some cases you may need to fix ioconfig...

Hi Fredric ,

If its the same hardware , then there is no need to make any changes. You just unplug the root hard disk while L2000 is off and then plug it in into the new L2000.Power it on! That's all.

Conflicts or systems panic occur if the root
scsi id is changed ( ie jumpers settings). If you do make such changes, then you need to apply the procedure mentioned by Nelson Caparroso.
