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_220.127.116.11.0_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
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
