Had a drive fail in a machine that we took out of production about 2 weeks ago. Hows that for timing? Apparently the linux aacraid driver and/or Dell perc2/si do not handle drives disappearing from a RAID1 volume very well, since the machine wouldn’t do anything besides spew ext3 errors until it was rebooted. Login and put the afacli quick ref to use, and disk 0:02:0 had failed, didn’t even come online long enough to get inited by the card. The machine is still under a Dell extended warranty, so I gave them a call and a new drive should be here on Tuesday.

Some of the more handy commands:
open afa0
container list
enclosure list
enclosure show slot
enclosure prepare slot <enclosure id> <slot id>
disk list
