One question - with "including hotplug", does that mean some set hotplug
standard? Reason I'm asking is, we have a few servers from SuperMicro,
with a ICH5R S-ATA controller that claims it's supporting hotplug, but
hotplug is not in your ICH5-summary.
Alas, there is no hotplug support in the ICH5 or ICH5-R SATA hardware.
One could argue there is "coldplug" support in that hardware -- disable the entire interface, including any active devices, then re-enable and re-scan -- but it's a bit of a hack. If there's enough demand, I could write some code for that. It would involve something like
# /sbin/sata off
{ plug in or remove a device }
# /sbin/sata on
You really, really, really don't want to actually unplug a SATA drive while it's active, on ICH5 hardware.
How does it work on other hardware?
