Remove faulty disk LV from VG
Hi,

Have mirrored the primary disk to 3 .

Server and OS:
# uname -a
HP-UX pdwp1s B.11.11 U 9000/800 118434630 unlimited-user license

# model
9000/800/L3000-7x


Code:
# strings /etc/lvmtab
/dev/vg00
+F@<
/dev/dsk/c1t2d0
/dev/dsk/c2t2d0
/dev/dsk/c2t0d0

But now I have only 1 disk active (Other 2 removed ).. But am failed to remove the red marked disk from VG00 .. .

Here's the present status
Code:
# vgdisplay -v vg00
vgdisplay: Warning: couldn't query physical volume "/dev/dsk/c2t0d0":
The specified path does not correspond to physical volume attached to
this volume group
vgdisplay: Warning: couldn't query all of the physical volumes.
--- Volume groups ---
VG Name                     /dev/vg00

# lvlnboot -v
lvlnboot: Couldn't query physical volume "/dev/dsk/c2t0d0":
The specified path does not correspond to physical volume attached to
this volume group

Now I want to remove the above VG error as something expecting like this .

Code:
# strings /etc/lvmtab
/dev/vg00
+F@<
/dev/dsk/c1t2d0

## Have tried below
# vgreduce vg00 /dev/dsk/c2t0d0
vgreduce: Couldn't query physical volume "/dev/dsk/c2t0d0":
The specified path does not correspond to physical volume attached to
this volume group

# mv /etc/lvmtab /etc/lvmtab_
# vgscan -av
# vgchange -a y /dev/vg00
vgchange: Volume group "/dev/vg00" does not exist in the "/etc/lvmtab" file.

Please suggest the Solution steps ...

vgdisplay

VGDISPLAY(8)						      System Manager's Manual						      VGDISPLAY(8)

NAME

       vgdisplay - display attributes of volume groups

SYNOPSIS

       vgdisplay  [-A|--activevolumegroups]  [-c|--colon]  [-d|--debug] [-D|--disk] [-h|--help] [-s|--short] [-v[v]|--verbose [--verbose]] [--ver-
       sion] [VolumeGroupName...]

DESCRIPTION

       vgdisplay allows you to see the attributes of VolumeGroupName (or all volume groups if none is given) with it's physical and  logical  vol-
       umes and their sizes etc.

   OPTIONS
       -A, --activevolumegroups
	      Only select the active volume groups.

       -c, --colon
	      Generate colon seperated output for easier parsing in scripts or programs.

	      The values are:

	      1  volume group name
	      2  volume group access
	      3  volume group status
	      4  internal volume group number
	      5  maximum number of logical volumes
	      6  current number of logical volumes
	      7  open count of all logical volumes in this volume group
	      8  maximum logical volume size
	      9  maximum number of physical volumes
	      10 current number of physical volumes
	      11 actual number of physical volumes
	      12 size of volume group in kilobytes
	      13 physical extent size
	      14 total number of physical extents for this volume group
	      15 allocated number of physical extents for this volume group
	      16 free number of physical extents for this volume group
	      17 uuid of volume group

       -d, --debug
	      Enables additional debugging output (if compiled with DEBUG).

       -D, --disk
	      Show  attributes	from  the volume group descriptor area on disk(s).  Without this switch they are shown from the kernel.  Useful if
	      the volume group isn't activated.

       -h, --help
	      Print a usage message on standard output and exit successfully.

       -s, --short
	      Give a short listing showing the existence of volume groups.

       -v, --verbose
	      Display verbose information containing long listings of physical and logical volumes.  If given twice, also display verbose  runtime
	      information of vgdisplay's activities.

       --version
	      Display version and exit successfully.

DIAGNOSTICS

       vgdisplay returns an exit code of 0 for success and > 0 for error:

       1  error reading VGDA
       2  volume group doesn't exist
       3  not all physical volumes of volume group online
