Is this information contained anywhere on my system? I'm looking for a simple solution to do hot-swappable SCSI RAID mirroring (one drive goes bad, the system stays up, I swap it when I get the chance sort of thing) under FreeBSD 3.x or 4.x. Does this require a significant amount of hardware? I would imagine I would need a couple of bay enclosures that have the electronics to support hot-swap, a card that allows the swap (and supports RAID), and appropriate drives. Are there any vendors for these products that are better than others? Anybody to stay away from? Also, is it possible to have two different sized disks in a RAID array? (i.e. I install two 9 GB SCSI disks, and later I can't find any 9 GB disks to replace a failed one with...would a 12 GB disk work?) Do they have to be exactly the same RPM? As always, any answers or comments you have would be greatly appreciated. ----------- Robert Wall sales@web-walrus.com Web Walrus Media 405 S Farwell St #23C Eau Claire, WI 54701 (715) 855-0189 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
