Cannot remove lvol (Faulty disk)

[luissma]

Hi,

I have a failing disk that I'd like to remove/put back in my Volume Group (disk has been physically replaced) but I have a mirrored volume in a not very good state that has one of the sides in stale state and the other one in unknown condition because of the old failing disk that prevents me from doing any operation:

# lvdisplay -v /dev/vg01/lvol3
lvdisplay: Warning: couldn't query physical volume "/dev/dsk/c1t0d0":
The specified path does not correspond to physical volume attached to
this volume group
lvdisplay: Warning: couldn't query all of the physical volumes.

I'd like to get rid of this volume to recreate it afterwards.

# lvremove -f /dev/vg01/lvol3
lvremove: Couldn't query physical volume "/dev/dsk/c1t0d0":
The specified path does not correspond to physical volume attached to
this volume group
lvremove: Couldn't delete logical volume "/dev/vg01/lvol3":
The specified logical volume is open, or
a sparing operation is in progress.

Trying to reduce the mirror:

# lvreduce -A n -k -m 0 /dev/vg01/lvol3 /dev/dsk/c1t0d0
Physical extents on remaining physical volumes are stale or
Remaining physical volumes are not responding.
lvreduce: The LVM device driver failed to reduce mirrors on
the logical volume "/dev/vg01/lvol3".

# lvreduce -A n -k -m 0 /dev/vg01/lvol3 /dev/dsk/c2t0d0
Physical extents on remaining physical volumes are stale or
Remaining physical volumes are not responding.
lvreduce: The LVM device driver failed to reduce mirrors on
the logical volume "/dev/vg01/lvol3".

Trying to reduce the Volume

# vgreduce -f /dev/vg01
Not all extents are free. i.e. Out of 4340 PEs, only 4332 are free.
You must free all PEs using lvreduce/lvremove before the PV can be removed.
Example: lvreduce -A n -m 0 /dev/vg01/lvol1.
         lvremove -A n /dev/vg01/lvol1
Here's the map of used PEs

         --- Logical extents ---
         LE      LV              PE     Status 1
         0000    lvol3           1838     current

Could somebody give me a hand?

Thanks in advance.

After several operations tried following:

vgcfgrestore -n /dev/vg01 /dev/rdsk/c1t0d0
vgchange -a y /dev/vg01

That has left my volume in a reasonable status and has allowed me to do some operations with it

# lvdisplay -v /dev/vg01/lvol3
