    After adding the new NED24 NVMe expansion disk to the Power 10 9043-MRX server using the EJ2A adapter, the fcs adapter on port 0 now shows a child NVMe Discovery Controller. This change has caused a longer completion time for both rebooting and running cgrmgr. It impacted all the LPAR . Reference code 3040
