Adding mirroring to the root vg - HP Unix

1. pvcreate -B /dev/rdisk/c2t2d0
   • Create the PV on the second disk so that LVM can manage it
   • -B makes it a bootable volume
     
2. mkboot /dev/rdsk/c2t2d0
   • Installs the boot files on the second disk
     
3. mkboot -a "hpux-lq (;0)/stand/vmunix" /dev/rdsk/c2t2d0
   • Creates an autoboot file on the disk, with information on how to boot
     
4. vgextend /dev/vg00 /dev/dsk/c2t2d0
   • extends the volume group to include this second disk.
     
5. vgdisplay -v vg00
   • To verify that the second disk is now part of the volume group
6. lvlnboot -v
   • To verify that the system thinks this disk can boot
7. lvextend -m 1 /dev/vg00/lvol1 /dev/dsk/c2t2d0
   • This extends the logical volume to the mirrored disk, effectively creating the mirrored copy.
   • This command needs to be run for each logical volume in the volume group
