How do I recover disks from JBOD shown as ‘Unconfigured(bad)’?

This is common if you've powered on the Genesis NX Head unit BEFORE the JBOD.  Then the LSI MegaRAID will not have seen the JBOD drives and list them as unconfigured.

In LSI Megaraid Manager, force all Unconfigured Bad disk to Unconfigured Good.

Again in MSM, select the controller under "Logical" tab, then at the top, head to "Go To" > "Controller" > "Scan Foreign Configuration"

Scan devices should recongnize and recover the RAID configuration
