The Auto Config feature allows you to configure and provision all the components in a server (example, iDRAC7, PERC, and RAID) in a single operation by automatically importing an XML configuration file. All the configurable parameters are specified in the XML file. The DHCP server that assigns the IP address also provides the XML file details to configure the iDRAC7.
You can create the XML file based on the service tag of the servers or create a generic XML file that you can use to configure all iDRAC7s serviced by the DHCP server. This XML file is stored in a shared location (CIFS or NFS) that is accessible by the DHCP server and iDRAC(s) of the server being configured. The DHCP server uses a DHCP server option to specify the XML file name, XML file location, and the user credentials to access the file location.
When the iDRAC or CMC obtains an IP address from the DHCP server, the XML file is used to configure the devices. Auto-config is invoked only after the iDRAC7 gets its IP address from the DHCP server. If it does not get a response or an IP address from the DHCP server, then auto-config is not invoked.
If all the Dell PowerEdge servers in the DHCP server pool are of the same Model type and number, then a single xml file ( config.xml) is required. (This is the default XML file name.)
You can configure individual servers using different configuration files mapped using individual host names. In an environment that has different servers with specific requirements, you can use different XML filenames to distinguish each server. For example, if there are two servers – a PowerEdge R720 and a PowerEdge R520, you must use two XML files, R720-config.xml and R520-config.xml.
