Extending Striped LVM on xfs

hello,
i was wondering what best practice would be to grow a striped logical volume. the server is a VM and its striped logical volume consists of 4 RDMs.
my understanding would be to;
change RDM size at the vmware level
rescan scsi on the server (so reboot not required)
preform vgextend onto the new presented size
do lvextend
then do grow_xfs on the logical striped volume

or do i have to create 4 new separate RDMs of a same size to original
add these into volume group
extend volume group
extend logical volume
grow xfs

i will be testing this but would like other peoples experiences on what worked best?
