Do you mean HMC (HMA) reboot or just physical machine reboot?
According my understanding you can reboot HMC and it is independent from
SE reboot since both are separate virtual objects (virtual machines). Of
course reboot of physical machine affect all virtual objects/machines
under.
BTW: I do not suggest to reboot SE with no purpose, however it is
perfectly possible during normal operations. Temporary lack of SE will
not disrupt production, but some administrative operations (IOCDS
update, IODF activate, change LPAR weights) will be temporarily
unavailable.

Thats my understanding too Tom. According to our SSR, its a pain if they have
to reboot the HMC for whatever reason, they have to make sure the SE is
switched to the correct one so they don't reboot the Primary SE.

And there's the new HMA Hardware Management Appliance on the z15 that
eliminates the need for external HMC boxes. I haven't seen this yet,
but one rumor is that the existing 2 SE 1U boxes inside a mainframe
(which to me look exactly like rack mount HMC boxes anyway) will boot up
the HMC software first, then start a VM task which boots up the SE
software.
