lvlnboot -v not shown boot alternative device as Boot disk

[Sanjay Shinde]

Hi guys,
OS : HP-UX 11.0, H/w : N class serve,
Problem :
Root volume group like lvol2,3,4,5,6,7,8 has been mrror without mkboot -a, because of that lvlnboot -v is not showing Boot disk for alternative disk ( mirror disk).
Also :-
while mirroring lvol1 error message
Logical volume "/dev/vg00/lvol1" has been successfully extended.
lvlnboot: LIF information corrupt or not present on "/dev/dsk/c2t6d0".
Use the "mkboot" command to initialize the LIF area.

lvlnboot -v
Boot Definitions for Volume Group /dev/vg00:
Physical Volumes belonging in Root Volume Group:
/dev/dsk/c1t6d0 (0/0/2/0.6.0) -- Boot Disk
/dev/dsk/c2t6d0 (0/0/2/1.6.0)
Boot: lvol1 on: /dev/dsk/c1t6d0
/dev/dsk/c2t6d0
Root: lvol3 on: /dev/dsk/c1t6d0
/dev/dsk/c2t6d0
Swap: lvol2 on: /dev/dsk/c1t6d0
/dev/dsk/c2t6d0
Dump: lvol2 on: /dev/dsk/c1t6d0, 0

I tried with mkboot /dev/rdsk/#### and
mkboot -a "hpux -lq" /dev/rdsk/c2t6d0 and use overwrite (y/n) : y
Also tried lvlnboot -R
all lvol showing mirror
but lvlnboot -v not showing alternative boot disk as above.

Any itea, other than removing disk from vg00 and recreate mknod and mirror all lvol1,2,3..8 ?

Thanks in advance,
Sanjay Shinde

Hi Sanjay:

Did you 'pvcreate' specifying a bootable disk?

# pvcreate -B /dev/rdsk/cXtYdZ

I suggest that you break your mirrors, and build your disk again, beginning with the appropriate 'pvcreate -B' sequence.

Regards!

Hi Sanjay,

Did you use the -B option on the pvcreate command on the alt boot disk?
It's mandatory - it reserves the boot space.

Rgds,

Did you update the BDRA ?

# lvlnboot -r /dev/vg00/ /dev/vg00
# lvlnboot -b /dev/vg00/ /dev/vg00
# lvlnboot -s /dev/vg00/ /dev/vg00
# lvlnboot -d /dev/vg00/ /dev/vg00

root=/, boot=/stand, primary swap and dump is the same LV.

Sanjay,

Why don't you start fresh? Break out all the mirror, take out the disk from the vg00.
Do pvcreate -b on the disk and then perform mkboot and all other procedures to make the mirrored root disk.

[Sandip Ghosh]

Sorry , it should be pvcreate -B.

As this box is install using ignite tape from Ingite tape of same hardware machine,but different size root disk 9GB and 18 GB and I am not sure about pvcreate -B, but when I try
lvlnboot -r /dev/vg00/lvol1
lvlnboot: Physical Volume "/dev/dsk/c2t6d0" on which Logical
Volume "/dev/vg00/lvol1" resides is not a Boot Physical Volume.

So need to recreate all using
vgreduce /dev/vg00 /dev/dsk/c2t6d0
pvcreate -B
vgextend
mknod
and Mirror all lvol's

Thanks for evryone who reply.

Hi,

try,

mkboot -l /dev/rdsk/cxtydz
mkboot -a "hpux -lq (;0)/stand/vmunic" /dev/rdsk/cxtydz

lvlnboot -v /dev/vg00

Hope this helps.

It happens, because Ignite doesn't support the mirroring . You have to do everything seperately.

Sandip

You are correct, Ignite doesn't support bootable mirrored disks. You have to do it manually.
