I have a few 2950 that process mail. This morning I noticed I had several out of date drivers after a power outage. I updated the BIOS to v2.7.0  I updated the raid driver (perc 5/i) to 2.24.0.32 A07 I updated the perc 5/i firmware  to 5.2.2-0072 A09 I updated the ESM to 2.5.0 A00 (seemed odd that such a large upgrade would be an A00)  it was 1.something I updated the DRAC 5 from 1.4 to 1.65 Lastly I uninstalled OMSA 5.2 and installed 7.1 Sorry for all the setup, now the question. I get an "driver version is out of date" on the OMSA storage firmware / driver page.  This is a cut and paste from the versions. I see a 5.2.2-0076 firmware for perc 5E?  I see no newer driver.
