Description

Check Active IQ if this impacts your systems.

This article covers Platforms with NVRAM DIMMs / NVDIMMs. 

  • 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.
  • ONTAP Hardware Systems Documentation on NVRAM / NVDIMM - Install and maintain
  • For errors with system memory DIMMs, see: How to troubleshoot correctable memory errors on FAS and AFF systems
