David,
now hot-swap may not be supported on all interface types, that may be what
you have run into, but with SCSI or SATA you should be able to hot-swap
with the right controller.
That's actually the problem - Linux hot swap is virtually non-functional for
SCSI. You can write into the proper places in /proc, then remove and rescan to
get a new drive up, but I've found that the resulting OS state is flaky. This
is true of the latest 2.6 kernels and LSI and Adaptec SCSI controllers.
The problems I've seen are with Linux, not the controllers.
Interesting, I have had zero problems with Linux and SATA with LSI
controllers and hot plug. I wonder what the difference is. The LSI
controller even though SATA just uses the scsi driver.
