Mostly - nobody has all of this figured out. Also that you need to think
much of the time at partition level not disk level. It is quite sane to
share a disk between two hosts. GFS even allows shared writable access to
the same partitions.

To do stuff partition level you need uuids. You also in a SAN do probably need
some dynamic handling. Firstly a device can move while you are using it,
secondly you want multi-path support. Part of the SAN can fail and you need
to find alternative paths to a given disk.
