I would run the update from OMSA live. Once updated this shouldn't occur again.
Hi, Trying to update Intel x520 10GbE mezzanine NIC firmware on a M620 blade fails with following error: SUP0517: Unable to update the Ethernet X520 10GBE DP KX4-KR Mezz firmware to version 14.5.9.Detailed Description: The firmware image specified in the operation did not apply successfully. An internal error may have occurred. Recommended Action: Retry the operation. If the problem persists, download the latest update package from your service provider, and retry the operation. BIOS, iDRAC, Lifecycle Controller firmwares are latest. I have tried to do update from iDRAC and directly from Lifecycle Controller (using SUU), the same. Havent tried from OS yet. I want to update firmware because it refuses to obtain DHCP address when trying to boot from PXE to deploy OS. At the same time in Lifecycle Controller, in Network Setup I was able to successfully obtain address from DHCP and scan Dell's FTP site for firmware updates. Any ideas? Thanks. Egils
