The Dell™ Lifecycle Controller embedded technology on Dell PowerEdge™ 11G servers gives administrators and managers the ability to easily update the system from within the system. Pressing F10 during the boot process opens System Services, which includes Platform Updates, and the first option is to connect through File Transfer Protocol (FTP) to ftp.dell.com and download the latest updates. For connections in a secure area, there is a second option to perform the update process through a USB-connected storage device.

View these demos of the Lifecycle Controller to become more familiar with the interface. This page provides information on the process used for USB updates and helps with building a USB update device that can be used inside a secure facility.

The Update Process

The update process begins by first looking for the existence of two files in the \catalog directory of the root of the USB key:

• catalog.xml.gz
• catalog.xml.gz.sign

If they don't exist, or have been changed in any way, the update process will exit with an error.

After the files have passed verification, the catalog.xml.gz is decompressed and the catalog is parsed. Then a screen shows the current version of existing updates and any applicable newer versions. It will automatically select updates that are newer and provide the choice of deselecting to apply an update at a later time. The update packages will then be installed from their respective locations off the root of the USB key.

Creating the USB Key

At first glance one might think, "Hmmm, easy enough; I'll just replicate what I need from ftp.dell.com to the USB key." The problem is that the files are not separated by machine types. Drill down through the \BIOS folder alone and there are more than 5,000 files and more than 8 GB of data. Trying to replicate the entire ftp.dell.com site would require replicating more than 40 GB of data, which isn't the best use of Internet bandwidth to go that route.

Luckily, it is possible to reuse a recommended tool, Content Manager, which provides the ability to create a custom repository. Using this feature helps replicate the updates specific to the servers in a data center environment. Copying the files to the USB key and copying the catalog.xml.gz and catalog.xml.gz.sign files creates a working USB key.

Here are step-by-step instructions:

1.	Install Content Manager from the Systems Management Tools and Documentation DVD. The current version as of this writing is 6.0.1.
2.	Run Content Manager and select Create Custom Server Update Utility.

3.	Select a destination—in this example, C:\USB_Updates.

4.	Use the Shift or Ctrl key to select the servers to update. Important: Make sure to select the Linux packages.

5.	Wait for the files to download.

6.	Locate the files just downloaded. They will be in \CustomRepository\repository under the directory just created. In the example shown here they are located in C:\USB_Updates\CustomRepository\repository.

7.	Copy all these directories and files to the root of the USB key, with the exception of the Catalog.xml file—this is not the correct file for the Lifecycle Controller.
8.	Create a catalog directory off the root of the USB key.
9.	Download catalog.xml.gz and catalog.xml.gz.sign from ftp.dell.com, and copy these files to the \catalog directory on the USB key.

After creating a custom USB key for updates with the Lifecycle Controller, the contents should look similar to the following:

10.	Reboot the server, select F10 for System Services, select Platform Updates...USB Device, and then select the updates to apply.
