Does it work on FreeBSD? I've finally found some spare time to test the hot-swap capability of the IBM x3550 machines with FreeBSD 6.2-RELEASE-p8. Good news, it works as expected. Here's the info required to make it happen: Kernel configuration lines to include. Note that you can omit the AAC_DEBUG line. If you do so, you won't see anything in the logs when the controller is working. I've only tried debug level zero and you'll see below that it generates quite a lot of info. device aac # Adaptec FSA RAID device aacp # SCSI passthrough for aac (requires CAM) options AAC_DEBUG=0 # Set debug level from 0 to 3. Here's what FreeBSD reports: grep -i raid /var/run/dmesg.boot aac0: <IBM ServeRAID-8k> port 0x4000-0x40ff mem 0xcce00000-0xccffffff,0xcafe0000-0xcaffffff irq 17 at device 0.0 on pci2 aac0: Adaptec Raid Controller 2.0.0-1 aacd0: <RAID 1 (Mirror)> on aac0 Now when you pull a drive out from the machine, wait a around a minute or so and then plug it back in, you'll get those messages in /var/log/messages: +aac0: EventNotify(0) +aac0: (EnclosureManagement) EMPID 0 unit 1 event 17 +aac0: EventNotify(0) +aac0: (DeviceFailure) handle 1 +aac0: EventNotify(0) +aac0: (EnclosureManagement) EMPID 0 unit 1 event 31 +aac0: EventNotify(0) +aac0: (23) +aac0: EventNotify(0) +aac0: (ConfigChange) +aac0: EventNotify(0) +aac0: (FailoverChange) +aac0: EventNotify(0) +aac0: (ContainerChange) container 0,0 +aac0: EventNotify(0) +aac0: (23) +aac0: EventNotify(0) +aac0: (23) +aac0: EventNotify(0) +aac0: (ContainerChange) container 0,-1 +aac0: EventNotify(0) +aac0: (ContainerEvent) container 0 event 7 +aac0: EventNotify(0) +aac0: (ContainerChange) container 0,-1 +aac0: EventNotify(0) +aac0: (ConfigChange) +aac0: JobProgress (1) - running (3123200, 312317952) +aac0: (ConatainerRebuildMirror) container 0 +aac0: JobProgress (2) - running (6246400, 312317952) +aac0: (ConatainerRebuildMirror) container 0 [ ... removed a lot of similar JobProgress lines ... ] +aac0: (ConatainerRebuildMirror) container 0 +aac0: JobProgress (100) - finished (312317952, 312317952) +aac0: (ConatainerRebuildMirror) container 0 +aac0: EventNotify(0) +aac0: (23) +aac0: JobProgress (101) - success (312317952, 312317952) +aac0: (ConatainerRebuildMirror) container 0 +aac0: EventNotify(0) +aac0: (ContainerChange) container 0,-1 +aac0: EventNotify(0) +aac0: (ConfigChange) There you go.
