Disk Partitions and AdvFS

Is there any good reason to carve up partitions to utilize with AdvFS
domains vs. using 1 whole disk partition per domain?

i.e.

foo_domain -> dsk75a
bar_domain -> dsk75b
car_domain -> dsk75d
...

vs.

foo_domain -> dsk76c
bar_domain -> dsk77c
car_domain -> dsk78c

We have a system set up to utilize partitions vs. the whole disk
approach. It seems like a bad idea to me (i.e. it seems better to me to
do all partitioning at the SAN level). Is there any good reason to do it
using partitions at the OS disk level?

Thanks.
