Frequently asked questions

What should I do if my Dell R450 shows HWC8010 and UEFI0459 errors during startup?

To resolve HWC8010 and UEFI0459 errors, first reseat the PERC 755 RAID card and any associated risers, ensuring they are in the correct slots. Next, access the BIOS/iDRAC settings to accept the current hardware configuration as valid. If the issue persists, check for firmware updates or temporarily remove the PERC card to see if the error clears. [community thread]

What should I do if my PowerEdge R740xd is stuck at boot after switching from RAID to HBA mode?

To resolve the boot issue, revert the PERC controller back to RAID mode via iDRAC and perform a cold power cycle for 30 to 60 seconds. After rebooting, access the System Setup to delete any old UEFI boot entries, clear all configurations in the PERC settings, and ensure that your BIOS, iDRAC, and PERC firmware are updated before switching back to HBA mode. [community thread]

What cables and components are needed to retrofit an R440 server for NVMe support?

For retrofitting the R440 to support NVMe drives, it's advisable to refer to the user manual for accurate cabling instructions. A PCIe extender card may be necessary if utilizing the SAS drive slots, and ensure that the SAS cables are of adequate length to connect to the HBA card. [community thread]

What does the PCI1318 error mean on a T440 server and how can it be resolved?

The PCI1318 error on a T440 server may indicate an issue with the Broadcom network interface cards when using kernel versions greater than 6.5. Disabling these network cards in the system BIOS can allow the server to boot without errors. Alternatively, replacing the network card with a compatible one can also resolve the issue. [community thread]

Why can't I see my PCIe storage card drives as boot options in the R740xd?

Ensure that the PCIe storage card is compatible with the R740xd, as only specific models are validated for this server. Additionally, check the BIOS settings to confirm that the boot mode is correctly configured. [community thread]
