 ### Provisioning newly added PowerEdge servers in the cluster
 To provision newly added servers, wait till the iDRAC IP addresses are automatically added to the *idrac_inventory*. After the iDRAC IP addresses are added, launch the iDRAC template on the AWX UI to provision CentOS custom OS on the servers.
