A post mostly for documentation sake on how to upgrade the firmware of the Onboard Administrator of an HP BladeSystem enclosure.

The update is a very straight forward process that can be done entirely through the OA web administration interface.

Go to Active Onboard Administrator –> Firmware Update.


From that screen you can upload the firmware from your system or enter an URL where the image is available. For our example we are going to use the upload option. Browse to the firmware image file and click Upload.

The OA web administration interface will logout any connected user and will start the upgrading process.


During the upgrade a progress bar like the one in the above screenshot will be shown and the OA will be reset when the process is complete.


Finally log into the OS and from the Active Onboard Administrator screen check the OA version.



One nice feature of the HP Onboard Administrator used to manage the c-Class Blade Enclosures is the posibility to generate a report in plain text format that contains the configuration of the enclosure and the whole inventory, including device bays, interconnect modules, MAC, WWNs, etc.

This report can be very useful for troubleshooting purposes and it’s for sure that if you have a problem with an enclosure and open a case to HP Support the Show All report will be amongst the first things you’ll be asked for.

Login into the enclosure Onboard Administrator administration interface. From the main screen go to Enclosure Settings -> Configuration Scripts.

You will see the interface to upload your customized scripts, a text box to point to an URL where the script is stored and two links named SHOW CONFIG and SHOW ALL.

Click the SHOW ALL link, a new window or tab will open and after a few seconds a report will appear.

Save it to your system and you are done. Now you can open the file with any text editor to look into the enclosure data.


Installing an ESXi server, or any other operative system, using the c-Class Blade Enclosure Onboard Administrator and the server ILO is a very easy and straightforward process. The Onboard Administrator integrates with each blade server iLO, allowing pass-through authentication.

From the OA main screen go to Device Bays and select the blade server where you want to install the ESXi on, from there enter the iLO section.

In the iLO area of the server launch a console applet; as you can see in the below screenshot there are several options, choose the one the better suits your environment.

I personally choose Remote Console. When the console is up you’ll see a menu, open the Virtual Drives menu. Here you can map a physical drive from your PC/Laptop, an USB Key or an ISO image.

With the media mapped to the blade server reset the server from the Power Switch menu and launch the ESXi installation like in any other server. By default it boot from the DVD if not from the boot screen press F11 to launch the Boot Menu.

If everything goes as expected after a few minutes you will have a new ESXi server. Just remember to disconnect the virtual drive from the blade once the ESXi is installed or it will boot again from the ISO image after the reboot of the server.

Finally is important to point out that the install process can be launched simultaneously to several servers using the same ISO image.
