I have a supermicro 1U with hot-swappable drive bays which hold 2 SATA drives that are connected to a PCI highpoint rocket raid card. I need to be able to simulate a failure on HDD1 (drive bay 2) and I've been trying to do it by following the handbook here: [18.4.3] http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/raid.html to no avail.
atacontrol detach ata3
<pull drive out>
<wait some time>
<put drive in>
atacontrol attach ata3
<HDD is recognized and listed in 'list' command>
atacontrol addspare ar0 ata3
Now this is when I encounter a "Device Busy" error. In order to recover from this I've tried detaching and attaching to no avail, rebooting just makes atacontrol status ar0 only show disk 1 even though disk 2 (ata3) is listed in atacontrol list. See below for a transcript from the shell, hopefully someone can provide some insight. Also this happens even if a drive fails.
