Bootable mirror disk

Yvonne Butler — Fri, 22 Oct 2004 06:04:53 GMT

I've been trying to get a bootable mirror disk configured but lvlnboot -v is still showing the 2nd disk as not bootable (see below):
Boot Definitions for Volume Group /dev/vg00:
Physical Volumes belonging in Root Volume Group:
/dev/dsk/c1t2d0 (0/0/1/1.2.0) -- Boot Disk
/dev/dsk/c2t2d0 (0/0/2/0.2.0)
Boot: lvol1 on: /dev/dsk/c1t2d0
Root: lvol3 on: /dev/dsk/c1t2d0
Swap: lvol9 on: /dev/dsk/c1t2d0
Dump: lvol9 on: /dev/dsk/c1t2d0, 0

I've run the following commands to create the bootable mirror disk, see below:
pvcreate –f –B /dev/rdsk/c2t2d0
mkboot –l /dev/rdsk/c2t2d0
mkboot –a “hpux –lq” /dev/rdsk/c2t2d0
vgextend /dev/vg00 /dev/dsk/c2t2d0
lvextend –m 1 /dev/vg00/lvol1 /dev/dsk/c2t2d0
lvextend –m 1 /dev/vg00/lvol2 /dev/dsk/c2t2d0
lvextend –m 1 /dev/vg00/lvol3 /dev/dsk/c2t2d0
lvextend –m 1 /dev/vg00/lvol4 /dev/dsk/c2t2d0
lvextend –m 1 /dev/vg00/lvol5 /dev/dsk/c2t2d0
lvextend –m 1 /dev/vg00/lvol6 /dev/dsk/c2t2d0
lvextend –m 1 /dev/vg00/lvol7 /dev/dsk/c2t2d0
lvextend –m 1 /dev/vg00/lvol8 /dev/dsk/c2t2d0
lvextend –m 1 /dev/vg00/lvol9 /dev/dsk/c2t2d0 lvextend –m 1 /dev/vg00/lvol10 /dev/dsk/c2t2d0
lvlnboot -R
setboot -p 0/0/1/1.2.0
setboot -a 0/0/2/0.2.0
lvlnboot –v

Still the 2nd disk isn't bootable according to lvlnboot -v.

Hello Yvonne,

It is a bit diffecult reading the above output.

check this doc for the steps.

Try the following -
lvlnboot -r /dev/vg00/lvol3 /dev/vg00
lvlnboot -b /dev/vg00/lvol1 /dev/vg00
lvlnboot -s /dev/vg00/lvol2 /dev/vg00
lvlnboot -d /dev/vg00/lvol2 /dev/vg00
lvlnboot -R
lvlnboot -v

I've looked at the cookbook and it doesn't give me anything I haven't already tried.

As for Michael's suggestions, I've tried these commands but lvlnboot -v still doesn't show the 2nd disk (c2t2d0) as bootable.

The results of lvlnboot -v is:

Boot Definitions for Volume Group /dev/vg00:
Physical Volumes belonging in Root Volume Group:
/dev/dsk/c1t2d0 (0/0/1/1.2.0) -- Boot Disk
/dev/dsk/c2t2d0 (0/0/2/0.2.0)
Boot: lvol1 on: /dev/dsk/c1t2d0
/dev/dsk/c2t2d0
Root: lvol3 on: /dev/dsk/c1t2d0
/dev/dsk/c2t2d0
Swap: lvol9 on: /dev/dsk/c1t2d0
/dev/dsk/c2t2d0
Dump: lvol9 on: /dev/dsk/c1t2d0, 0

Hi,

You forget to do lvlnboot for all volumes

lvlnboot -r (root lvol path)
lvlnboot -b (boot lvol path)
lvlnboot -s (swap lvol path)
lvlnboot -d (dump lvol path)

Its ok everyone, I've found the problem... The disk had already been in the lvmtab and was already mirrored but wasn't bootable. I've therefore started again basically by taking the mirrors off, removing the disk from lvmtab and starting over. Straight away after running everything up to mkboot -a "hpux -lq" etc... the 2nd disk appears as bootable in lvlnboot -v.

Thanks everyone, it was the cookbook that got me thinking on the right tracks...
