New Drives Attached to a Nytro MegaRAID Controller
When you insert a new drive on a Nytro MegaRAID system, if the inserted drive does not contain valid Nytro Flash module metadata, the drive displays as JBOD for Nytro MegaRAID entry-level controllers. If the drive contains valid Nytro Flash module metadata, its drive state is Unconfigured Good.
Automatic rebuilds always occur when the drive slot status changes, for example, when you insert a drive or remove a drive, so that a Commissioned Hotspare can be used.
(Rebuilds start only on Unconfigured Good drives.) After you set the drive state to Unconfigured Good, the drive state information always remains on the drive, and you can use the drive for configuration.
See Troubleshooting Information for more information about Nytro Flash module and metadata. See Making a Drive Offline or Missing for the procedure to change a drive to the Unconfigured Good drive state.
