I had Nagios telling me there was a memory issue on the server, but not in which slot the bad ram was located. OM to the rescue?

Download oem-dell-openmanage-esxi_6.3.0-A00.zip (I’m running on a Dell PowerEdge 2850 Server)
Use the VMWare VSphere CLI to run the following:

vihostupdate.pl –server SERVERNAME_OR_IP -i -b “C:\oem-dell-openmanage-esxi_6.3.0-A00.zip”
Enter the username (root)
Enter the Password (password)

Then, using the Dell Web Server administrator (OM-SrvAdmin-Dell-Web-WIN-6.3.0-2075_A00.20.exe), connect to your virtual machine and IGNORE CERTIFICATE ERRORS!
