This one's been bugging for a long time and I finally decided to seek an answer. I find lots of people with the same issue but all the answers/suggestions direct the questioner to fix a hardware problem.
I've been using ESXi 4.1 (Dell edition) on my PE 2900 with PERC/6i card for over two years (running fine) but with the ESXi vSphere Health Status screen displaying disturbing messages (attached screen shots). The event log does not have any hardware issues.
I just rebuilt this server with new drives. Thought that getting all the firmware updated and ESXi 5.x installed would show me a clean Health Status screen - but no.
I installed Win 2008 r2 with the latest Dell drivers and OpenManage, checked the status and everything says it's fine. All the hardware checks out fine and the system appear very happy. Also checked the RAID via the BIOS and all is fine.
Is this just something I have to live with? Thanks for any light that could pointed my way.
