Symptoms
During the Power On Self-Test (POST) phase, the system may encounter issues with single or multi-bit ECC messages, or experience unplanned data unavailability related to the Dell PowerEdge RAID Controller (PERC).
Cause
PERC Firmware memory handling
Resolution
Fix:
Update the PERC10 firmware version to 51.16.0-5148 for H840.
Update the PERC10 firmware version to 51.16.0-5150 for H740, H740p, and H745.
Updated firmware includes Improved DDR4 Memory settings to prevent critical DDR4 memory errors that may result in a controller stop responding condition, including Single Bit Errors (SBE) and Multi Bit Errors (MBE)
Important Note: Once the firmware update is complete, it is crucial to perform a complete graceful shutdown to power off the system. A power on to enable the new memory settings must be performed after.
Caution: A warm reboot or system reset DOES NOT activate the updated memory settings. If the Integrated Dell Remote Access Controller (iDRAC) or Lifecycle Controller (LC) is used to perform the update, a graceful shutdown to power off the system after the update is still required.
Dell Technologies recommends upgrading at the earliest available opportunity to prevent future occurrences of this issue, regardless of whether it has been observed.
