I received an email this week from one of my readers / followers on twitter who had gone through the effort of upgrading his LSI controller firmware. He shared the procedure with me as unfortunately it wasn’t well documented. I hope this will help others in the future, I know it will help me as I was about to look at the exact same for my VSAN environment, thanks for sharing this Tom!

We do quite a bit of virtualization and storage validation and performance testing in the Taneja Group Labs (http://tanejagroup.com/). Recently, we were performing some tests with VMware’s VSAN and due to some performance issues we were having with the AHCI controllers on our servers we needed to revise our environment to add some LSI SAS 2308 controllers and attach our SSD and HDDs to the LSI card. However our new LSI SAS controllers didn’t come with the firmware mandated by the VSAN HCL (they had v14 and the HCL specifies v18) and didn’t recognize the attached drives. So we set about updating LSI 2308 firmware. Updating the LSI firmware is a simple process and can be accomplished from an ESXi 5.5 U1 server but isn’t very well documented. After updating the firmware and rebooting the system the drives were recognized and could be used by VSAN. Below are the steps I took to update my LSI controllers from v14 to v18. [Read more…]
