Mirroring the Root Volume Group on HPUX 10.20

[Lisa Moore]

I have just started an entry-level admin position and one of my first tasks involves mirroring the root volume group. I would appreciate any advice/instructions offered.

pvcreate -B /dev/rdsk/cxtxd0

vgextend /dev/vg00 /dev/dsk/cxtxd0

mkboot -l /dev/rdsk/cxtxd0

mkboot -a "hpux -lq (;0)/stand/vmunix" /dev/rdsk/cxtxd0

mkboot -a "hpux -lq (;0)/stand/vmunix" /dev/rdsk/cytyd0

lvextend -m 1 /dev/vg00/lvolx /dev/dsk/cxtxd0

lvlnboot -Rv /dev/vg00

setboot -a full hardware path (es:8/4.5.0)

hi,
and after the stuff Vincenzo gave you, which makes sure you have a bootable drive, you need to mirror the software

<>
lvextend -m 1 /dev/vg00/lvol1 /dev/dsk/cxtyd0
lvextend -m 1 /dev/vg00/lvol2 /dev/dsk/cxtyd0
lvextend -m 1 /dev/vg00/lvol3 /dev/dsk/cxtyd0


lvextend -m 1 /dev/vg01/lvol4 /dev/dsk/cxtyd0
lvextend -m 1 /dev/vg01/lvolx /dev/dsk/cxtyd0

good luck,
Thierry.

Hi Lisa:

As a general guide to common administration tasks (particularly working with LVM to extend filesystems and/or mirror logical volumes), I would look at "HP-UX System Administration Tasks":
