Making Different Types of Drives
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.
If the controller supports JBOD drives, the LSI Storage Authority includes options for converting JBOD drives to an unconfigured good drive, or vice versa.
You can make the following types of drives:
- Unconfigured
- Good
- JBOD
