Secure Erase of an Exadata System

What has to be done when the Lifecycle of an Exadata System comes to the end.

You need to do an secure erase of DB and Storage nodes.

By the way you can also secure erase the Switches and PDU, etc. but this is not described in this article.

and  My Oracle Support Doc ID 2180963.1

Steps to do

I use the method via bootable USB Stick

Download Boot Image via Patch 25470974

You need a complete list of all DB and Storage node names including all IP addresses of each ILOM Server

Tip: Before you start reset the password on each Server for example „welcome1“

Prepare USB Stick

I use my Mac book and do a „dd“ to copy the image to the USB Stick

dd if=image_diagnostics_12.2.1.1.0_LINUX.X64_170126.2-1.x86_64.usb of=/dev/disk2

Start a ILOM Web Console Login for the first Server

In parallel start a ILOM terminal console session to do a restart of the first Server

While the reset is running the Web  Console came up with the BIOS Splash screen. Please  enter


<CTRL+P>

It takes a while and you see the boot menu

Select the USB Stick and press enter to start

the Boot Screen appears

Now it is time to check the output on the ILOM terminal console. You will see after a while a „login:“ prompt


Login as "root" password "sos1exadata" or "sos1Exadata"

If the password doesn’t work contact Oracle Support for help
