Dell EMC NVDIMM-N Persistent Memory User Guide

BIOS Error Messages

When BIOS detects an NVDIMM-N related error during POST, BIOS displays an F1/F2 prompt and a corresponding error message. Multiple messages will appear when multiple errors were detected. BIOS will also log an event for each error in the Server System Event Log (SEL) and Life Cycle Log (LCL). Please refer to the JEDEC JESD245B spec for more information on each NVDIMM-N related failure. NVDIMM-N [Location] is the memory slot location as shown in Figure 5.

UEFI0302* NVDIMM-N Not Ready or Not Responding on NVDIMM-N located at [Location].

This NVDIMM-N module will be set to read only mode. Remove input power to the system, reseat the NVDIMM-N module, and restart the server. If the issue persists, replace the faulty memory module identified in the message.

UEFI0302* Save Error on NVDIMM-N located at [Location].

This NVDIMM-N module will be set to read only mode. Remove input power to the system, reseat the NVDIMM-N module, and restart the server. If the issue persists, replace the faulty memory module identified in the message.

UEFI0302* Restore Error on NVDIMM-N located at [Location].

This NVDIMM-N module will be set to read only mode. Remove input power to the system, reseat the NVDIMM-N module, and restart the server. If the issue persists, replace the faulty memory module identified in the message.

This NVDIMM-N module will be set to read only mode. Remove input power to the system, reseat the NVDIMM-N module, and restart the server. If the issue persists, replace the faulty memory module identified in the message.

UEFI0303 Lifetime Percentage <= 5% on NVDIMM-N located at [Location]. The identified NVDIMM-N module is approaching the end of its functional life.

Please plan to replace the NVDIMM-N module during the next scheduled maintenance. For more information, please refer to the server Installation and Service Manual.

UEFI0304 Unable to enable the NVDIMM-N Save operation because Server is not Armed. All NVDIMM-N modules will be set to write-protect mode. Please verify that the battery is operational, and that the server has sufficient power to support this configuration.

UEFI0304 Unable to enable the NVDIMM-N Save operation because Battery is not present. All NVDIMM-N modules will be set to write-protect mode. Please verify that the battery is operational, and that the server has sufficient power to support this configuration.

UEFI0304 Unable to enable the NVDIMM-N Save operation because Battery is not ready. All NVDIMM-N modules will be set to write-protect mode. Please verify that the battery is operational, and that the server has sufficient power to support this configuration.

UEFI0304 Unable to enable the NVDIMM-N Save operation because Server is not Armed. All NVDIMM-N modules will be set to write-protect mode. Please verify that the battery is operational, and that the server has sufficient power to support this configuration, and that NVDIMM Write-Protect mode has not be enabled in BIOS Setup.

UEFI0340 NVDIMM-N Running from Backup Firmware Image at [Location].

Update the NVDIMM-N to the latest firmware. If the issue persists, replace the faulty memory module identified in the message.

UEFI0341* NVDIMM-N Lifetime Percentage <= 1% on NVDIMM-N located at [Location].

This NVDIMM-N module will be set to read only mode. Replace the NVDIMM-N module.

The following two BIOS messages are modular specific and will only be seen on an NVIDMM equipped server in the event that there are no management modules installed in the modular chassis or the installed management modules are not capable of detecting an power loss event.

Table 1. BIOS Error messages with event ID's and event messagesThe following table provides BIOS Error messages with event ID's and event messages
ID Event Message
UEFI0364* Unable to detect chassis power loss, memory may not be persistent. Ensure there are two functional chassis management modules. If there is only a single chassis management module, only perform a firmware update on it when server modules with persistent memory are powered off.
UEFI0365 Chassis is able to detect power loss, memory is persistent. No response action required.

* Errors marked with an asterisk may result in data loss.
