monitoring raid arrays

[Elliot Finley]

How about monitoring the array on a Dell PowerEdge 2650?
relevant dmesg output:

FreeBSD 6.0-RELEASE-p2 #0: Mon Jan 16 12:27:14 MST 2006
aacch0: <AAC RAID Channel> port 0xcc00-0xccff mem 0xfccff000-0xfccfffff irq
30 at device 6.0 on pci5
aacch1: <AAC RAID Channel> port 0xc800-0xc8ff mem 0xfccfe000-0xfccfefff irq
31 at device 6.1 on pci5
aac0: <Dell PERC 3/Di> mem 0xf0000000-0xf7ffffff irq 30 at device 8.1 on
pci4
