Symptoms

Observed Issues After Firmware Update:General Detection Failure:The controller is not detected during system boot across all management interfaces. iDRAC - storage tab shows no controllerOS - controller absent in OS and the perccli2 CLI toolHII - controller missing from the hardware inventory Log and Error Messages: Lifecycle Controller (LC log): PR8 device not detected.Affected Controllers: Controller Model H965i Front H965i Adapter H965i MX H965e Adapter H965i Front DC-MHS Affected Firmware Versions: Firmware Versions 8.8.x.x 8.11.x.x

Cause

When updating PERC12 controllers to firmware version 8.14.x.x, the update process requires an offline activation step after the DUP update. During system boot, the Remote Management Controller (RMC) fails to reload, producing a fault that blocks controller detection across all interfaces.This condition occurs in firmware versions 8.8.x.x and 8.11.x.x. Updating to the fixed version 8.14.x.x prevents the issue from recurring. Note: This issue may appear after the first reboot following the transition to firmware version 8.14.x.x, but it does not occur again after that.

Resolution

Issue is addressed in PERC firmware 8.14.0.0.18-14.Workaround:If the Controller Is Not detected after the firmware update on the first reboot: Perform a power cycle to restore detection: From iDRAC, go to Power Controls and select Power Cycle System (cold boot). ORPower cycle the server. Caution: Performing the update on a live production system may cause temporary storage unavailability. Schedule the update during a maintenance window.
