8.7.6 New Drives Attached to a
MegaRAID Controller
When you insert a new drive on a MegaRAID system, if the inserted drive does not
contain valid DDF metadata, the drive displays as JBOD for MegaRAID entry-level
controllers, such as the SAS 9240-4i/8i. If the drive does contain valid DDF metadata, its
drive state is Unconfigured Good.
A new drive in JBOD drive state is exposed to the host operating system as a
stand-alone drive. Drives in JBOD drive state are not part of the RAID configuration
because they do not have valid DDF records. The operating system can install and run
anything on JBOD drives.
