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: 2025-06-27 06:49:46 81749 SUP0520 Unable to update the iDRAC firmware to version 1.20.50.50. 2025-06-27 06:48:03 81746 RAC0182 The iDRAC firmware was rebooted with the following reason: unknown. 2025-06-27 06:40:54 81735 SUP0516 Updating firmware for iDRAC to version 1.20.50.50. 2025-06-27 06:39:42 81731 RED110 Downloading the iDRAC-with-Lifecycle-Controller_Firmware_59D8W_WN64_1.20.50.50_A00.EXE update package. 2025-06-27 06:39:41 81730 JCP027 The (installation or configuration) job JID_509703816535 is successfully created on iDRAC. 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 an error is encountered, the server displays 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"
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
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. The affected iDRAC releases because of this issue are as in below table: Released Version Version New Version available on Support site June iDRAC Release 1.20.50.50 1.20.50.52 July Release 1.20.51.10 1.20.51.12 Power Edge R7725XD 1.20.53.10 1.20.53.12
