or
Plus did you try

I tried to restore previous archive. still i am getting the same issue.

[root@rhel5 /]# vgremove myVG
Do you really want to remove volume group "myVG" containing 1 logical volumes? [y/n]: y
Do you really want to remove active logical volume myLV? [y/n]: y
  Unable to deactivate open myVG-myLV-real (253:2)
  Unable to deactivate logical volume "myLV"

why i am unable to remove the VG.

Can you check the volume status:

lvs

Select allOpen in new window

Plus make sure......

There is no other indication that the LV or VG is open or in use. The 'df ' command reports no mounted filesystems. Neither 'fuser ' nor 'lsof ' report any open files related to this LV.

Check this link, "Why can’t I remove a Linux logical volume? and Cannot Deactivate LVM Logical volume

[root@rhel5 src]# lvs

[root@rhel5 src]# pvremove /dev/sdb
  Can't open /dev/sdb exclusively - not removing. Mounted filesystem?

To remove an inactive logical volume, use the lvremove command. You must close a logical volume with the umount command before it can be removed. In addition, in a clustered environment you must deactivate a logical volume before it can be removed.
