S2000-025: IBM AIX v7.3 Administrator Specialty

cfgmgr runs the AIX Configuration Manager, which detects and configures newly connected storage devices such as a newly presented LUN. The disk must be recognized and configured by AIX before it can be prepared for use by Logical Volume Manager; creating a volume group is a later LVM operation. IBM documents cfgmgr as the command used to detect and configure a newly connected disk.
