I ended up figuring this out, but I didn't see this solution anywhere, so let me post it. BIOS Version: 2.16.0iDrac Firmware Version: 2.84.84.84Lifecycle Controller Firmware: 2.84.84.84System Revision: I (Is there a revision II?) Server: Dell PowerEdge r730xd RNDC Dell P/N: 6VDPGA (2*1Gb rj45 + 2 sfp+ ports)   Download 19.5.12 firmware from here. Install in iDrac web gui. Download 20.0.17 firmware from here. Install in iDrac web gui.   I basically had to do incremental update manually, but finding the v19 firmware was a little difficult. Each flash took about 5-6 minutes once it booted into lifecycle to start the firmware flash before it completed the flash.   I have a feeling the discrepency here is how the different interfaces of the card are inventoried, the second sfp+ interface does not match the rest and I have a feeling this is throwing off the update logic.  Dell should probably fix that.
Curious if anyone knows why this won't update, am I missing something?  This is in iDrac.  When I try to update firmware in LCC I get a completely different error, it doesn't even make it as far as the iDRAC.LCC error attached with red bar up top "Critical". [IMAGE]     [IMAGE][IMAGE]
