How do I remove quorum from my system disk?

[Joe Profaizer]

I initially had my system disks mirrored. However, I ignited the system and wrote the ignite tape to the other mirror disk without breaking the mirror first. I can now boot using:
hpux -lq, but now that I have the system up, how can I set my system disk (dev/dsk/c2t6d0) to never need quorum to boot?

Thanks,

..JOe

1) lvreduce -m 0 each LVOL.
2) vgreduce the VG.

Hi,

You can remove the missing disks from the vg00 to solve this.

#strings /etc/lvmtab

Will list the other disk in vg00 and with vgreduce you can reduce that disk from vg00. If the other disk listed in /etc/lvmtab is missing then you should use

#vgreduce -f /dev/vg00

If the disk is attached to system then

#vgreduce /dev/vg00 /dev/dsk/cxtydz
Where cxtydz is the other disk in vg00.

Another way of doing it will be put "hpux -lq" as the default boot string in AUTO file. But this is not the recomended way.

HTH,

Hi Joe:

My question back to you would be why wouldn't you want to re-mirror your boot disk?

I would certainly want to do so, and then would want to set the low quorum on *both* disks so that if there was a failure, I would automatically boot:

# mkboot -a "hpux -lq" /dev/rdsk/cXtYdZ #...on BOTH disks...
# setboot -a [alternate_path] #...for newly mirror disk...
# lifcp /dev/rdsk/xCtYdZ:AUTO - #...verify the boot string...

Regards!
