Connectivity issue between the extents of a logical volume when extended

Dear Awadhesh,

Basically I am reading my hard disk through Winhex(ver-13.5) and I am unable to make the connectivity between the extents of a logical volume within a volume group. As in my last query I have told that I have made a Logical Volume Group of 50GB, in which I have created 2 logical volumes(LogVol01 and LogVol02), both of 10 GB. After some time the disk space allocated for first logical volume(i.e. 10GB) gets filled, then I further extended this logical volume by 10GB. Now the total disk spcae allocated to my first logical volume is 20GB. So now, if you check it through WinHex first it keeps 10GB of first logical volume, then 10GB of second logical volume and then again 10GB of first logical volume, which I have extended later. Now my question is where exactly it keeps this information that from which particular sector or offset it will keep its extent. As i have to make a connectivity between the first 10GB of first logical volume and its extent which is also of 10GB that I got after the second logical volume. Now I think I have made my point more clear to you.
Ask to me if there is any confusion yet.

Regards
Himanshu

vxdestroy_lvmroot

vxdestroy_lvmroot(1M)													     vxdestroy_lvmroot(1M)

NAME

       vxdestroy_lvmroot - remove LVM root disk and associated LVM volume group

SYNOPSIS

       vxdestroy_lvmroot [-v] [-b] lvm_root_disk

DESCRIPTION

       The  vxdestroy_lvmroot  command	tears  down  and removes the LVM volume group associated with the specified physical disk. This is done by
       removing the volumes in the volume group and then removing the volume group.

OPTIONS

       -b	 Invokes the setboot command to change the primary boot disk to the VxVM root disk from which the system was booted (if  the  pri-
		 mary  boot  disk is not already set to this disk).  The alternate boot device remains unchanged.  If the -v option is also speci-
		 fied, the settings of the primary and alternate boot devices are displayed.

       -v	 Outputs verbose messages including a timestamp that indicates major operations being performed.

ARGUMENTS

       lvm_root_disk
	    Specifies the device name of the LVM root disk that is to be destroyed, along with its entire volume group.

EXAMPLES

       This example shows the vxdestroy_lvmroot command invoked in its simpliest form:

       /etc/vx/bin/vxdestroy_lvmroot c5t1d0

       # /etc/vx/bin/vxdestroy_lvmroot -v -b c3t0d0
       Are you sure about destroying c3t0d0 (imported on VG /dev/vg02) ? YES
