Injects an error or clears a previously injected error

Synopsis

ipmctl set [OPTIONS] -dimm [TARGETS] [PROPERTIES]

Description

Injects an error or clears a previously injected error on one or more PMem module for testing purposes.

Options

-h, -help

Displays help for the command.

-ddrt

Used to specify DDRT as the desired transport protocol for the current invocation of ipmctl.

-smbus

Used to specify SMBUS as the desired transport protocol for the current invocation of ipmctl.

Note

The -ddrt and -smbus options are mutually exclusive and may not be used together.

-o (text|nvmxml), -output (text|nvmxml)

Changes the output format. One of: "text" (default) or "nvmxml".

Targets

-dimm [DimmIDs]

Injects or clears an error on specific PMem modules by supplying one or more comma separated PMem module identifiers. The default is to inject the error on all manageable PMem modules.

Properties

This command only supports setting or clearing one type of error at a time.

Clear

Temperature

Injects an artificial media temperature in degrees Celsius into the PMem module. The firmware that is monitoring the temperature of the PMem module will then be alerted and take necessary precautions to preserve the PMem module. The value is injected immediately and will override the firmware from reading the actual media temperature of the device and use this value instead which may cause adverse reactions by the firmware and result in an alert or log.

Note

The injected temperature value will remain until the next reboot or until it is cleared. The media temperature is an artificial temperature and will not cause harm to the part. Although firmware actions due to improper temperature injections may cause adverse effects on the PMem module.
If the Critical Shutdown Temperature, or higher, is passed in, this may cause the PMem module firmware to perform a shutdown in order to preserve the part and data.
The temperature value will be ignored on clear.

Poison

The physical address to poison.
Poison is not possible for any address in the PM region if the PM region is locked. Injected poison errors are only triggered on a subsequent read of the poisoned address in which case an error log will be generated by the firmware, but no alerts will be sent.
This command can be used to clear non-injected poison errors. The data will be zero’d after clearing. There is no requirement to enable error injection prior to request to clear poison errors.
The caller is responsible for keeping a list of injected poison errors, in order to properly clear the injected errors afterwards. Simply disabling injection does not clear injected poison errors. Injected poison errors are persistent across power cycles and system resets.

Note

System firmware (BIOS) will not read from any Intel™ Optane™ PMem device addresses that are known to be poisoned. For any poisoned address, the first read may result in a hang/fault, but system firmware (BIOS) will mark this address as poisoned so subsequent attempts to read poisoned addresses will be rejected with an error. The result of such an error may prevent booting from a namespace that has poisoned data.

Note

The address must be 256 byte aligned (e.g., 0x10000000, 0x10000100, 0x10000200...).

PoisonType

The type of memory to poison. One of:

  • "PatrolScrub": Injects a poison error at the specified address simulating an error found during a patrol scrub operation indifferent to how the memory is currently allocated, This is the default.
  • "MemoryMode": Injects a poison error at the specified address currently allocated in Memory Mode.
  • "AppDirect": Injects a poison error at the specified address currently allocated as App Direct.

Note

If the address to poison is not currently allocated as the specified memory type, an error is returned.

PackageSparing

PercentageRemaining

Injects an artificial percentage remaining value into the PMem module. This will cause the firmware to take appropriate action based on the value and if necessary generate an error log, an alert, and update the health status.

FatalMediaError

Note

When media fatal error is injected, BSR Media Disabled status bit will be set indicating media error, until the fatal error is cleared using disable trigger input parameter to clear this injected fatal error.

Note

Injecting a Fatal Media error is unsupported on Windows. Contact Microsoft for assistance in performing this action.

DirtyShutdown

Examples

Sets the media temperature on all manageable PMem modules to 50 degrees Celsius.

ipmctl set -dimm Temperature=50

Clears the injected media temperature on all manageable PMem modules.

ipmctl set -dimm Clear=1 Temperature=1

Poison address 0x10000200 on PMem module 1234.

ipmctl set -dimm 1234 Poison=0x10000200

Clears the injected poison of address 0x10000200 on PMem module 1234.

ipmctl set -dimm 1234 Poison=0x10000200 Clear=1

Triggers an artificial package sparing on all manageable PMem modules.

ipmctl set -dimm PackageSparing=1

Sets the life remaining percentage on all manageable PMem modules to 10%.

ipmctl set -dimm PercentageRemaining=10

Clears the injected remaining life percentage on all manageable PMem modules. The value of PercentageRemaining is irrelevant.

ipmctl set -dimm PercentageRemaining=10 Clear=1

Triggers an artificial ADR failure on all manageable PMem module s resulting in a dirty shutdown on each PMem module on the next reboot.

ipmctl set -dimm DirtyShutdown=1

Limitations

This command is available only when error injection is enabled on the PMem modules in the BIOS. To successfully execute this command, the specified PMem modules must be manageable by the host software.

Return Data

For each PMem module, the CLI will indicate the status of the operation. If a failure occurs when injecting an error on multiple PMem modules, the process will continue with the remaining PMem modules.
