homeyjoe, thank you for the post.

Just wondering why you have changed the logical volume type to copy ?

2. changed new lv to be type 'copy'

I didn't do this step, but would like to know the reason behind changing the type. When I created a logical volume and tried to copy it ( as i mentioned in the previous post ) i got an error and the message was :: Change the type of the logical volume with chlv command ...
At that time, i didn't understand why it needs to be changed and into what ...

So, I skipped, and I let the system create the logical volume and copy....So, when I chose the second option, I am not sure if AIX will automatically change the logical volume type to copy ?

Also, after successful mounting do i need to change the type to something else in-order to make the logical volume into write mode ?

lvdisplay

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

NAME

       lvdisplay - display attributes of a logical volume

SYNOPSIS

       lvdisplay [-c|--colon] [-d|--debug] [-h|-?|--help] [--ignorelockingfailure] [--maps] [-P|--partial] [-v|--verbose] LogicalVolumePath [Logi-
       calVolumePath...]

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 is recommended over lvdisplay.

OPTIONS

       See lvm for common options.

       -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.

Examples
       "lvdisplay  -v  /dev/vg00/lvol2"  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 /dev/vg00/snapshot" shows the attributes of this snapshot logical volume and also which original logical volume it is associated
       with.
