#pvcreate /dev/dsk/...

Initialize disks for use in lvm.

#vgextend -g PVG0 /dev/vgsmp /dev/dsk/...
#vgextend -g PVG1 /dev/vgsmp /dev/dsk/...

By this you will extend the respective pvg with named disks. See /etc/lvmpvg for changes.

What does lvdisplay -v /dev/vgsmp/lvsmp | more says (first lines of output till logical extents mapping)? See allocation, mirroring etc. Then we will continue with lvextend and fsadm (provided you have onlinejfs installed).
