mpt0 and removing disks

[Matthew Jacob]

  I'll repeat what I've said before: mpt was not designed to support 
hotplugging. There is *some* support for it for the Fibre Channel HBAs, 
but I don't know if they even work.

That doesn't mean it couldn't be changed for this. The problem here is 
that this would require a fair amount of work for what is now obsolete 
hardware. I doubt you can get too many people interested in this.

As for 'warm plugging', that's doable. Make sure nothing is using the 
device you want to pull, give indication to pull it, and issue 
'camcontrol rescan' after it is out and/or replaced with another drive.

I wasn't paying attention to the early part of the thread, so I don't 
know if this is a procedural alternative.
