How to troubleshoot correctable memory errors on 62XX, 32XX, 25XX, and 22XX systems in ONTAP

Last Updated:

Applies to

  • ONTAP 9
  • FAS22xx
  • FAS25xx
  • FAS / V32xx
  • FAS / V62xx


Note: For all other ONTAP versions and platforms see: How to troubleshoot correctable memory errors on FAS and AFF systems

NetApp controllers feature error-correcting code (ECC) memory modules (DIMM) for both main memory and the NVRAM subsystem. Correctable memory errors are handled automatically, with no intervention and no impact on system performance. Correctable ECC error messages are located in the system log or EMS event log.

Correctable ECC errors are not an indicator that an uncorrectable ECC error will occur. Uncorrectable memory errors will cause a system disruption (panic). If a system disruption occurs, the panic message will call out the DIMM or DIMMs where the uncorrectable error occurred, those DIMMs should then be replaced.

Check Active IQ if this impacts your systems.
