Symptoms
iDRAC10 firmware version 1.20.50.50 has been removed from Dell Technologies' eSupport downloads website due to two high impact issues. Symptoms include failure to update from older firmware versions to firmware 1.20.50.50 and exposure to an unresponsive iDRAC10 condition.
Update Issue:
While updating the iDRAC10 firmware from any earlier version to 1.20.50.50, the update job may fail. When this issue is encountered, the life cycle Log records a RAC0182: The iDRAC firmware was rebooted with the following reason: Unknown during the update sequence.
Life cycle Log Example:

Unresponsive Issue:
Rebooting an iDRAC10 that has been running firmware version 1.20.50.50 for over 50 days becomes unresponsive. The failure requires that server input power is removed to remediate this condition. Potential exposure could return in another 50 days after recovery. When error is encountered, server will display RAC0185 error event during POST.
"RAC0185": { "Description": "iDRAC or BMC cannot be started because of an internal issue.", "Message": "Unable to start iDRAC or BMC because of an internal issue - %1. See the message: RAC0185.", "MessageSeverity": "Critical", "NumberOfArgs": 1, "ParamTypes": [ "string" ], "Resolution": "Perform an AC Power Cycle operation by doing the following:1) Disconnect the power cords from the server.2) Wait 30 seconds.3) Reconnect the power cords to the server.If the issue persists, contact the Technical Support team.", "Severity": "Critical"
Cause
The updated iDRAC10 firmware 1.20.50.50 u-boot EMMC logic fails when the BMC timer reaches a threshold value (49.71 days) since the last AC cycle of the server. Due to this eMMC driver issue, iDRAC10 u-boot was not able to access the eMMC storage. This leads to firmware update failure and loading kernel partition conditions
Resolution
Do not replace any hardware.
iDRAC10 firmware version 1.20.50.50 was removed from the eSupport downloads to prevent additional exposure to these symptoms. An updated driver is in firmware 1.20.50.52.
