Hi malki,

You need to lvreduce out the disk you don't want in the mirror anymore - as follows:

lvreduce -m 1 /dev/vg_name/lv_name /dev/dsk/cxtydz

Hi Malki:

You can make it happen with the lvreduce command:

# lvreduce -m 1 lv_name pv_name_you_need_to_release

This will remove the mirror copy from the specified disk. Check the lvdisplay output after doing this for confirmation:

# lvdisplay -v lv_name

HTH,
