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. - Luke
