To address high fan speeds on the Dell R740XD2, ensure you are using a supported operating system, as Flatcar is not officially validated for this server model. Consider switching to a supported OS like Ubuntu or Red Hat, which may allow for better fan control. If you continue to use Flatcar, be aware that Dell does not provide support for issues related to it. [community thread]
To resolve firmware upgrade issues, consider performing a staged upgrade by first updating to version 22.5.x before moving to 23.0.x. Additionally, try running the updates from a Live ISO environment and ensure that the BIOS and iDRAC versions are consistent across all systems. [community thread]
Ensure that the system firmware, including CPLD, BIOS, and iDRAC, is fully updated. You may also want to drain flea power by disconnecting all power and network cables, holding the power button for 20 seconds, and then waiting for 3 minutes before reconnecting. Additionally, check the BIOS settings to disable 1Gb options on the OCP NIC, leaving only 10Gb and 25Gb enabled. [community thread]
To upgrade the C6400 to an NVMe backplane, you will need the NVMe backplane itself and specific backplane cables. Note that the C6400 can only support 8 NVMe drives, and if you have a PERC H330 or H730 installed in the C6420 nodes, you will need to replace them with a PERC S140 or HBA330, as the former do not support NVMe. [community thread]
Ensure that the server's BIOS, iDrac, and H730 RAID controller firmware are all updated to the latest versions, as outdated components may interfere with the SSD firmware update process. If the issue persists, consider reaching out to support for further assistance. [community thread]
