Cisco UCS blade Discovery Failed with an error Invalid adapter-iocard combination.

iocard error

You may hit this error if you are not using recommended configuration for example:

  1. If you have 2104XP IOM and you are trying to install a blade with VIC1240 with a Port Expander adapter.( In this case just remove the port expander to make it work)
