In that case you may not want to be using LVM.

Most of the Linux filesystems have an extend capability, so that is not
a problem.

I don't know how to get the kernel itself to rescan the hardware for
capacity changes.  Obviously you can reboot, but there must be a better
way.

I would look for SAN documentation that describes the resize process. 
The commands will likely be exactly the same from the Linux perspective.
