The Coraid drives were configured as JBOD. Using minicom and a serial cable, type the following commands into the terminal.
list -l (shows which drives are online)
jbod 1.3 (used to export one or more drive slots as lblades)
On the server in a terminal window, type:
mdadm –detail /dev/md0
to determine which drive is missing or failed.
Next, add the new drive to the array using the following command:
mdadm /dev/md0 -a /dev/etherd/e1.3
Again, type mdadm –detail /dev/md0
