Spoke offline with the original poster. Here is a recap of the findings:
1. Moderate Faults experienced in DNA Center CIMC. Raid Controller fault w/ Virtual Drive 2 in a degraded state. OP will reseat the RAID controller if necessary to see the that resolves the RAID controller fault and brings VD2 back to a health state.
2. When re-imaging an entire 3 node cluster. Shut down the 2nd and 3rd node fully before re-imaging the primary node.
