I just received a notice during boot of a HP G8 server regarding iLO issues: “iLO 4 has detected a self test error. For details consult the iLO 4 server and iLO 4 diagnostics page”.
Went into the iLO diagnostics page (in the Blade Center admin) and found the error message “Controller firmware revision 2.07.00 Embedded media manager failed initialization”. Google does not give too much info regarding this, so it is a bit hard to see what is going on regarding this. I tried to restart both the blade and the iLO itself, but the error did not go away.
I had to contact HP regarding this, and the conclusion(after both having to try a firmware upgrade and firmware re install), was that it was a hardware error on the iLO storage, so HP had to replace the whole motherboard for that server.
