Removing faulty disks from mirror

[Rui Vilao]

Hi all,

I have an HP-UX 10.20 with mirrored disks.

A disk failed (I have no more maintenance for this host...).
I want to remove the mirror from the
logical volumes and remove the faulty disk from the Volume Group.
# strings /etc/lvmtab
/dev/vg00
cd7^
/dev/dsk/c0t6d0
/dev/dsk/c0t4d0
/dev/dsk/c0t5d0
/dev/dsk/c0t3d0

/dev/vgoradb

/dev/dsk/c3t0d3
/dev/dsk/c3t1d3

==> c0t5d0 is faulty

# lvdisplay -v /dev/vg00/lvol8

...

When I try:

# lvreduce -m 0 /dev/vg00/lvol8 /dev/dsk/c0t5d0
lvreduce: Warning: couldn't query physical volume "/dev/dsk/c0t5d0":
The specified path does not correspond to physical volume attached to

lvreduce: Warning: couldn't query all of the physical volumes.
lvreduce: Physical volume "/dev/dsk/c0t5d0" does not belong
to volume group "/dev/vg00".
Logical volume "/dev/vg00/lvol8" is not reduced.

# vgreduce /dev/vg00 /dev/dsk/c0t5d0
vgreduce: Couldn't query physical volume "/dev/dsk/c0t5d0":
The specified path does not correspond to physical volume attached to
this volume group

How can I remove the disk?

Thanks in advance for your help,

Kind Regards,

Rui.
