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.
Thanks for the clarification, I knew that PATA didn't do hotswap, and I've
seen discussions on the linux-kernel list about SATA hotswap being worked
on, but I thought that scsi handled it. how recent a kernel have you had
problems with?
