Subject: maturity of hotplug disk storage devices

Hi,
I am looking for some advice on the maturity of hotplug functions for
Linux disk storage devices. I looked into this two years ago and found
that although insertion/removal appeared to often work, in particular
with scsi, it was not really officially supported thru the entire
protocol stack at the time.
Now, I find evidence in general, hotplug support has improved,
presumeably positively influenced by subsequent USB and firewire
development. But disks are more complex than printers, scanners, etc so
Im having a difficult time forming an opinion about how "official" this
all is for disk storage. Have the improvements gotten into disk
storage related areas also? Should I really consider relying on hotplug
disk storage in a mission critical application?
Well, I would really be interested in any comments anyone had, privately
or publicly, on the maturity of hotplug disk storage in Linux 2.4. Does
insertion/removal of existing/new devices work reliably on IDE, SCSI,
Fibrechannel, USB, iee1394? Is it "officially" supported? Are you
using it on a mission critical machine? Do things like the MD driver
and LVM handle hotplugged drives reliably well?
Of course I assume appropriate hardware doing the right things
electrically and that any filesystem is unmounted.
Any help understanding the current state would be greatly appreciated!
Thanks,
Mark

P.S. Ive looked thru the LDP, google, and elsewhere with little luck;
apologies that I can't look at the home page for the hotplug project
because I am in China, and all sourceforge project home pages are
blocked. sigh.....
