No this is another set of server on which am testing the clone behaviors ..

Here what have did
# OS data alread in 1 mirrored state
# HAVE mirrored it to one more disk
# AND removed the third disk
# Then have run below script

Code:

# sh -x  lvmirr_b.sh
## cat lvmirr_b.sh
for i in 1 2 3 4 5 6 7 8 9
do
 # lvextend -m 1 /dev/vg00/lvol${i} /dev/dsk/c2t0d0    ## As have extended to  -m 2
 lvreduce -m 1 -A n -k  /dev/vg00/lvol${i} /dev/dsk/c2t0d0
done

# vgreduce -f  /dev/dsk/c2t0d0
# mv /etc/lvmtab /etc/lvmtab_9212
# vgscan -v 

### And now am getting above error 

### Below out for more desc..
 # lvdisplay -v /dev/vg00/lvol1

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

NAME

       lvdisplay - display attributes of a logical volume

SYNOPSIS

       lvdisplay  [-a|--all]  [-c|--colon]  [-d|--debug]  [-h|-?|--help]  [--ignorelockingfailure]  [--ignoreskippedcluster] [--maps] [--nosuffix]
       [-P|--partial] [--units hHbBsSkKmMgGtTpPeE] [-v|--verbose] [--version] [LogicalVolumePath [LogicalVolumePath...]]

       lvdisplay --columns|-C [--aligned] [-a|--all] [-d|--debug] [-h|-?|--help] [--ignorelockingfailure] [--ignoreskippedcluster]  [--noheadings]
       [--nosuffix]  [-o|--options [+]Field[,Field...]]  [-O|--sort [+|-]Key1[,[+|-]Key2...]]  [-P|--partial] [--segments] [--separator Separator]
       [--unbuffered] [--units hHbBsSkKmMgGtTpPeE] [-v|--verbose] [--version] [LogicalVolumePath [LogicalVolumePath...]]

DESCRIPTION

       lvdisplay allows you to see the attributes of a logical volume like size, read/write status, snapshot information etc.

       lvs(8) is an alternative that provides the same information in the style of ps(1).  lvs(8) is recommended over lvdisplay.

OPTIONS

       See lvm(8) for common options and lvs for options given with --columns.

       --all  Include information in the output about internal Logical Volumes that are components of normally-accessible Logical Volumes, such as
	      mirrors,	but  which are not independently accessible (e.g. not mountable).  For example, after creating a mirror using lvcreate -m1
	      --mirrorlog disk, this option will reveal three internal Logical Volumes, with suffixes mimage_0, mimage_1, and mlog.

       -c, --colon
	      Generate colon separated output for easier parsing in scripts or programs.  N.B. lvs(8) provides considerably more control over  the
	      output.

	      The values are:

	      * logical volume name
	      * volume group name
	      * logical volume access
	      * logical volume status
	      * internal logical volume number
	      * open count of logical volume
	      * logical volume size in sectors
	      * current logical extents associated to logical volume
	      * allocated logical extents of logical volume
	      * allocation policy of logical volume
	      * read ahead sectors of logical volume
	      * major device number of logical volume
	      * minor device number of logical volume

       -m, --maps
	      Display  the  mapping  of logical extents to physical volumes and physical extents.  To map physical extents to logical extents use:
	      pvs --segments -o+lv_name,seg_start_pe,segtype

       --columns, -C
	      Display output in columns, the equivalent of lvs. Options listed are the same as options given in lvs(8).

Examples
       Shows attributes of that logical volume. If snapshot logical volumes have been created for this original logical volume, this command shows
       a list of all snapshot logical volumes and their status (active or inactive) as well:

       lvdisplay -v /dev/vg00/lvol2

       Shows the attributes of this snapshot logical volume and also which original logical volume it is associated with:

       lvdisplay /dev/vg00/snapshot
