Can't un-mirror a disk

[Dario_1]

How can I un-mirror the root disk. vgreduce -m is complaining about an illegal option. HP-UX 11.11.

Thank you for your help.

Hi,

Maybe you meant to try 'lvreduce -m' ?

Hi:

# lvreduce -m 0 /dev/vg00/lvolX

...for each logical volume that is mirrored.

Regards!

Hi (again):

...since you probably should specify which disk (that's best), do:

# lvreduce -m 0 /dev/vg00/lvolX /dev/dsk/cXtYdZ

hi,

Assuming you have only one mirror volume and your disk is /dev/dsk/c2t6d0

for LVOL in /dev/vg00/lv*

> echo $LVOL
> lvreduce -m 0 $LVOL
> vgreduce /dev/vg00 /dev/dsk/c2t6d0
> done

Unfortunately, the mirrors are done at the Logical Volume level, so that's why you'd have to use the lvreduce -m 0 instead of vgreduce -m 0

And if this fails the please provide the exact error message. Thanks!
