/dev/dsk/c4t3d0 16384 16384
/dev/dsk/c6t11d0 16384 16384

You can use "pvchange" to immediately set the primary disk:

pvchange -s /dev/dsk/c6t11d0

(no need to specify the VG)

But "pvchange -s" is only valid until next reboot, because /etc/lvmtab will remain unchanged.

I tried this on the a test and then do a vgdiplay and it shows the original disk as primary.

I tried the pvchange -s, but when i do a lvdisplay -v, it still shows the same disk as the primary disk.
