nvdimm.nvmem.checkfail

Severity

EMERGENCY

Description

This message occurs when NVDIMM-based NVMEM checks fail.

Corrective Action

For all errors, check that the right type of NVDIMM is properly installed at the designated DIMM slot.

Syslog Message

NVMEM subsystem configuration check failed because %s. To prevent NVMEM data loss, halt the system.

Parameters

error (STRING): Description of the error, which could be: 1 device in slot-N is not accessbile. 2. device in slot-N is missing. 3. device in slot-N is not NVDIMM. 4. device in slot-N is the wrong size (N); expected size (N)

nvdimm.nvmem.destage.failure

Severity

ALERT

Description

This message occurs when NVDIMM fails to copy nonvolatile data to the flash on the NVDIMM-device.

Corrective Action

This type of error indicates that the volatile data on the local NVMEM has been lost. A storage system in an HA configuration might recover the NVMEM content from its partner. To prevent future possible data loss, take the appropriate actions based on the error: 1. If the failure is caused by a malfunctioning battery, contact NetApp technical support for assistance with battery replacement. 2. If the failure is caused by an NVDIMM intermittent hardware failure, contact NetApp technical support for assistance.

Syslog Message

NVMEM subsystem failed to copy nonvolatile data to flash memory on NVIDMM device because %s.

Parameters

error (STRING): Reason for destage failure could be: (1) SDRAM is not in self-refresh mode (2) energy source (battery) is not functioning properly (3) of insufficient battery (4) destage process timeout (5) an intermitten hardware error results partial data saved (6) of a hardware error (7) of a firmware error (8) of a flash error

nvdimm.nvmem.initfail

Severity

EMERGENCY

Description

This message occurs when the nvdimm-based NVMEM subsystem is not initialized succesfully.

Corrective Action

For all errors, check if the error is persistent or intermittent by power cycling the controller and rebooting ONTAP. Note: If the last reboot is a dirty shutdown, set the bootarg.init.battery_override to force system to replay the NVLOG first when booting. Then, gracefully shut down and power cycle the controller.. If the failure is persistent: (a) For error (1) (2) (3) (5) (6) (7) (8), contact NetApp technical support for assistance with replacement.of NVDIMM or upgrade NVDIMM firmware. (b) For error (4), b.1 If failure cause is battery, contact NetApp technical support for assistance with replacement of the battery. b.2 For other failures, contact NetApp technical support for assistance with replacement of NVDIMM. (c) For error (9), contact NetApp technical support for assistance with replacement of the controller. (d) For error (10), verify the NVDIMM is installed properly and check if the correct BIOS is installed.

Syslog Message

NVMEM subsystem initialization failed because %s. To prevent NVMEM data loss, halt the system.

Parameters

error (STRING): Description of the error, which could be: 1.NVDIMM device in slot-N not accessible. 2.NVDIMM device in slot-N not ready. 3.NVDIMM device in slot-N is busy. 4.NVDIMM device in slot-N lost persistence due to [reason] 5.NVDIMM device in slot-N has worn-out flash (N percent remaining) 6.NVDIMM device in slot-N failed to configure energy source 7.NVDIMM device in slot-N failed to configure saveNPin. 8.NVDIMM device in slot-N failed to enable data preservation. 9.failed to enable battery. 10.NVDIMM memory address not mapped contiguously.

nvdimm.nvmem.restage.failure

Severity

ALERT

Description

This message occurs when nonvolatile data on the NVDIMM is either corrupt or not accessible. Because these errors cannot be corrected, nonvolatile data in flash memory is lost.

Corrective Action

Frequent occurrence of these errors indicates that the NVDIMM is experiencing persistent intermittent hardware failure. Contact NetApp technical support for assistance with replacement.

Syslog Message

NVMEM subsystem failed to restore nonvolatile data from flash memory on the NVIDMM module because of %s.

Parameters

error (STRING): Reason for restage failure could be: (1) SDRAM is not in self-refresh mode (2) of SDRAM uncorrectable error (3) restage process timeout (4) of a hardware error
