MegaRAID SAS Controller Replacement Procedure OL-27138-01 Replacement Preparations Make sure you have received the new MegaRAID card (LSI MegaRAID 9261-8i). Ensure that the BBU is either on the card or present in the box. Make sure you have downloaded the initrd.img installer which will install the new SAS driver to support the new MegaRAID controller. This installer will need to be copied over to the server that its MegaRAID controller will be replaced with the new one.
