yep, i'd say you had a drive failure. lodged a hardware call and got
dell to replace the disk ?

the driver can get into a state where this happens. i've tried various
things to get around it with no success. a reboot, or sometimes a
power cycle fixed the inability to use afacli.

it _should_ automatically rebuild, even if you can't enter afacli.

replace the drive. wait for a short while. then reboot the box (note,
not power cycle, just try a reboot. if this fixes it, great. if it
doesn't, you might want to wait for the rebuild to finish (which could
take from 2-X hours depending on capacity of disks and load), and then
power cycle the machine.
alternatively, a (possibly riskier) approach is to reboot/power cycle
the box (as needed) and then replace the disk. this allows you to
use afacli to verify the rebuild operation.
