Hi Steve,
	Thanks for the clarification. As I mentioned earlier in this thread, it should still \
be possible to monitor raid configurations from evmsgui and flag events such as a \
degraded array and allow devices to be marked faulty, remove and add devices from \
inside the GUI, without having to restart the GUI. I would think that the refresh \
button is for this purpose. Though the GUI does provide these features they don't \
seem to work when the changes in the raid array happen when the GUI is up. \
Particularly given that these things are doable now through another tool like mdadm, \
I am assuming that this should be eminently doable now without any additional kernel \
support. Am I missing something here ? Appreciate your comments on this, 

Ramesh.

Actually, we just took hotplug out of the plan.  :(  The hotplug support in
the kernel is not what we thought it was.  We were hoping it had a way for
a program to register to be called for hotplug events.  In reality, all it
is is that the kernel calls a fixed script name to active the hotplug
device (SCSI, PCI, or USB).
