A Dell system uses system software (BIOS and other firmware such as RAID controller firmware, PCIe-SSD firmware, Network Card Interface (NIC) firmware etc.) and required Linux operating system. General practice is to first install required Linux operating system and later perform the system software inventory and/or updates. Here we are providing a one stop solution for installing required Linux operating system followed by inventory and update of system software. In this way, we end up with using a Dell system with required Linux OS installed and also with latest system software (BIOS and firmware) in use.
Note: Dell provides software products such as "Dell Deployment Tool Kit", "Dell System Build Update Utility", and so on that use "Dell Update Packages (DUPs)" for updating system software on Dell systems. We don't use them here.
Here we are considering installation of RHEL v6.x on a Dell system using an example Kickstart file that is shown below to achieve above mentioned one stop solution. This example Kickstart file uses "Dell Linux Online Repository" and other RHEL v6.x specific installation configuration details.
"Dell Linux Online Repository" and "Dell Update Packages"--------------------------------------------------------------------Dell provides "Dell Update Packages (DUPs)" for BIOS and system software updates to use with Dell systems. We can also make system software updates using "Dell Linux Online Repository".
Dell Linux Online Repository URL: http://linux.dell.com/repo/hardware/latest/Dell Update Packages User Guides/Manuals URL: http://support.dell.com/support/edocs/software/smdup/
User Guides/Manuals provide more information about "Dell Linux Online Repository" and other DUP details. "Dell Linux Online Repository" contains Dell OMSA, drivers, BIOS and firmware updates. It is possible to create local mirror site equivalent to "Dell Linux Online Repository".
Example Kickstart File--------------------------
Comments are included in the example Kickstart file to provide more information to the readers. This example Kickstart file uses "Dell Linux Online Repository" to complete required BIOS and other firmware inventory and updates. The system automatically reboots if we use the following Kickstart file to install RHEL v6.x that includes post install BIOS and other firmware inventory/updates also. Readers may need to edit/comment/uncomment contents of this example Kickstart file to suit their requirements. The following is sequence of actions that occur during the RHEL v6.x installation using the following Kickstart file. All these actions do not require user intervention.
1) Anakonda starts and complete installation as per configuration details explained in the Kickstart file 2) Set Up/Bootstrapping "Dell Linux Online Repository" 3) Install required firmware tools/packages from "Dell Linux Online Repository" 4) System automatically downloads applicable firmware from "Dell Linux Online Repository" 5) Do an "Inventory" check on the system (creating inventory XML file, that is /var/log/pre_update_inventory.xml) to know the available/installed BIOS and other firmware versions 6) Update both BIOS and other firmware on the system to their latest available versions on "Dell Linux Online Repository" 7) Update /etc/rc.local file to complete the following (post reboot): 7.1) Inventory again (second time) to confirm completed updates. Second time inventory will be /var/log/post_update_inventory.xml 7.2) Uninstall (clean) installaed firmware tools/packages, delete downloaded firmware, and so on 7.3) Undo updates done to /etc/rc.local file 8) Reboot host to boot to OS 9) Complete pending firmware updates, if any. 10) Boot to OS and autoexecute /etc/rc.local 11) Wait for login

### END: EXAMPLE KICKSTART FILE ###
Summary (Post log-in) 1) We can check /var/log/pre_update_inventory.xml and /var/log/post_update_inventory.xml files that provide pre and post "BIOS and firmware updates" inventory details. Above explained example Kickstart file contents and the log file of its execution are stored in the /tmp directory to assist with debugging installation and system software updates' details. So please check these log files in /tmp/ directory for debugging. 2) The file /var/log/firmware-updates.log provides more details about system software updates' that were applied to the system using the explained example Kickstart file. 3) The example Kickstart file is really useful to deal with many physical servers that require RHEL v6.x OS installation followed by latest system software (BIOS and other firmware) inventory and/or updates. 4) Currently we can also achieve the explained one stop solution with other RPM based Linux distributions also.
