start system-config-lvm
select a volume group "delta" which contains /dev/sda{11,12,8}

The picture displays the "red" pv's as this:
   sda8 sda12 sda11
This is the reverse of "the right order."

Note that under the "delta Physical View | /dev/sda" (in the left pane), the
order is:
   Partition 11
   Partition 12
   Partition 8
which is also the order in which the pv's get allocated to a lv.
This is "the right order".

Please change the order used for the overall graphical display.
