You can not extend an older filesystem with striping.  Also, striped
partitions must be the same size.  In the above example, you would have
to make sure that dks0d1s6 and dks0d4s7 were the same size.  But since
it appears you want to extend an already existing filesystem, you should
remove the ":stripes=2" field, and then everything should work.
Remember, after the
	mklv lv1
execute
	growfs /dev/dsk/lv1
to extend your older filesystem onto the new disk.
