Re: Change PV Link path

You can use vgreduce and vgextend to reorganize Alternate links.

vgreduce /dev/vg11 /dev/dsk/c19t0d2
vgextend /dev/vg11 /dev/dsk/c19t0d2

and vg11 will become to:
PV Name /dev/dsk/c13t0d2
PV Name /dev/dsk/c18t0d2 Alternate Link
PV Name /dev/dsk/c15t0d2 Alternate Link
PV Name /dev/dsk/c19t0d2 Alternate Link

One thing I don't understand is that why you expect the "Total PE" will be reduced from 6945 to 5208?

Yes either you can do vgreduce and then vgextend or try this single command
pvchange -s /dev/dsk/c13t0d2
this will set the /dev/dsk/c13t0d2 as the primary disk
