Symptômes
Alert Indicating DIMM Issue
The system reports the following alert:
PPDMA DM5510 Alert CTL47 - Single-bit ECC error on the specified DIMM
Cause
DIMM Hardware Failure Triggering ECC Alerts
The DIMM has experienced a hardware malfunction that generates a single‑bit ECC error. The PPDMA DM5510 Alert CTL47 alert code identifies this condition and indicates that the memory module cannot reliably store or retrieve data.
- DIMM internal circuitry has degraded or failed, causing error detection mechanisms to mark a single‑bit ECC fault.
- The system firmware reports this error:
PPDMA DM5510 Alert CTL47
This pinpoints the affected DIMM. - Because the DIMM is part of the controller battery pack, its failure directly impacts the controller’s ability to maintain data integrity.
- Data loss or corruption may occur if the faulty DIMM continues to operate.
Continued operation of a malfunctioning DIMM can lead to irreversible data loss or corruption.
Résolution
Replace the DIMM immediately.
- The DIMM is a part of the controller battery pack.
- Refer to your hardware documentation for information about replacing the DIMM.
