I agree about the reboot part...apparently, with SDD on AIX, the vpath
will failover on the event of the loss of one link to the surviving
link(s), but it will not "fail back" when the link is restored, unless you
reboot.
AIX seems to be the only platform (that I have seen) for which this is
true.
We ran into that, and thought it was something that we were doing wrong;
spoke to one of the switch vendors, and they confirmed it.
