	I've not used the Shark stuff, so I don't know.  What sense to
you mean "/dev/vpathaa1 is a partition"?  Do you mean "I have a device
/dev/vpathaa, I ran fdisk /dev/vpathaa, now I have a partition
/dev/vpathaa1"?  Or do you mean "I have a partition /dev/sda1 and a
partition /dev/sdc1, they are linked via vpath to /dev/vpathaa1"?  The
former should absolutely work.  The latter won't, I'd bet, because the
vpath code would be advertising it as a whole device, not a portion of a
bigger device.
