Need experiences regarding booting from SAN

Proposed environment is a mix of p670s and p630s. IBM
business partner is pushing booting from SAN (Shark).
Customer (and I) favor booting from internal disks,
because of our mutual feeling that this is more
RELIABLE (while more inflexible).

Questions:

1. If you're booting from SAN (or did in the past),
what problems/advantages did you encounter?
2. What SAN solution, pSeries solution, and fiber HBA
combination were you using?
3. Does a particular SAN solution (EMC, Shark,
Hitachi) make it easier/harder to implement SAN
booting?
4. Any issues with migrations/updates/mksysb
restores?
5. Other commentary.

I still prefer booting from internal disks (and
including SAN disks as non-boot rootvg disks if I
must), but I realize that there must be some real
advantages....
