Make Unconfigured Good and Make JBOD
When you power-down a controller and insert a new physical drive and if the inserted drive does not contain valid DDF metadata, the drive status is listed as JBOD (Just a Bunch of Drives) when you power the system again. When you power-down a controller and insert a new physical drive and if the drive contains valid DDF metadata, its drive state is Unconfigured Good. A new drive in the JBOD drive state is exposed to the host operating system as a stand-alone drive. You cannot use JBOD drives to create a RAID configuration, because they do not have valid DDF records. Therefore, you must convert JBOD drives to unconfigured good drives.
