Hello,
I have a volume group that has one logical volume and it spans 6 LUN's. I want to replace one LUN in this 6 with another one. It is not striped.
Can I use this {pvmove /dev/dsk/c1t0d0 /dev/dsk/c2t0d0} like in the man page?
I am not sure as the man page is 100% clear when there is a LV that spans more than one LUN.
Any help appreciated.

Sure, you can use pvmove to move the PEs from one LUN to the other even if the LV spans multiple LUNS
# pvcreate /dev/rdsk/
# vgextend /dev/vg01 /dev/dsk/
# pvmove /dev/dsk/c1t0d0 /dev/dsk/
pvmove can fail if the system is not current on LVM patches.
I would recommend a backup of the LV before executing pvmove. Also make sure you dont interrupt the command in between :-)
If you can take a downtime of the system, install the latest LVM cumulative patch before going ahead with the change
# pvcreate /dev/rdsk/
# vgextend /dev/vg01 /dev/dsk/
# pvmove /dev/dsk/c1t0d0 /dev/dsk/
