I. Replacing a Boot disk in PA-RISC

II. Replacing Mirrored Boot disk in PA-RISC: [If the disk is hot-swappable]

--- Replacing a Boot disk in PA-RISC ---

1. Detach the disk and replace the disk
# pvchange -a N /dev/dsk/cXtXdX -----> replaced disk
(Optional)# lvreduce -m 0 -A n /dev/vg##/lvol# <PV list>
2. Repopulate the LIF area
# mkboot /dev/rdsk/cXtXdX -----> replaced disk
3. Change the AUTO file contents as apropiate: 
A) Primary boot disk
# mkboot –a “hpux” /dev/rdsk/cXtXdX
B) Alternate boot disk 
# mkboot –a “hpux –lq” /dev/rdsk/cXtXdX
4. Restore the LVM reserved areas
# vgcfgrestore –n vg00 /dev/rdsk/cXtXdX -----> replaced disk
5. Reattach the new disk
# pvchange -a y /dev/dsk/cXtXdX
6. Reactivate the VG to recognize the recovered disk
# vgchange –a y vg00
7. Resynchronize mirrors
# vgsync vg00


Replacing Mirrored Boot disk in PA-RISC: [If the disk is not hot-swappable]
-------------------------------------------------

1. Initiate the boot sequence:
# shutdown –hy 0

2. Replace the damaged disk.
The damage disk is one of the boot disk mirrors? No, jump to step 6.

3. Interrupt the PDC boot sequence.
[Escape]

4. Boot from the good mirror disk, with quorum disable.
SEA IPL

Choose the boot disk:
P#

Interact with IPL?
yes
hpux –lq -is    <----single user

5. In the HP-UX system prompt, force HP-UX to recognize the replaced disk:
# insf –eC disk

6. Restore the LVM reserved areas (PVRA/VGRA):
# vgcfgrestore –n vgXX /dev/rdsk/cXtXdX   -----> replaced disk

7. Repopulate the LIF area:
# mkboot /dev/rdsk/cXtXdX -----> replaced disk

8. Change the AUTO file contents choosing the best policy for the boot path: 

A) Primary boot disk.
# mkboot –a “hpux” /dev/rdsk/cXtXdX

B) Alternate boot disk.
# mkboot –a “hpux –lq” /dev/rdsk/cXtXdX

9. Reactivate the volume group to attach the physical volume.
# vgchange –a y vgXX

Note: In case that the volume group don’t start to synchronize the logical volumes automatically, you can force synchronization with:

# vgsync vgXX
