No, I've had several SCSI drive failures in software raid and the kernel will gracefully log the errors, mark the drive failed in the md array and go on about its business. This doesn't happen with typical IDE devices, but the 3ware isn't a typical IDE controller. If you do everything in the right order, you can replace a failed hot-swap scsi drive and rebuild the software raid without shutting the machine down. -- Les Mikesell lesmikesell at gmail.com
