Setting %1\%2 is invalid. Verify that %2 is a DWORD (32-bit) value in the range %3 to %4 (inclusive). The default value of %5 will be used for this setting until the error is corrected.

Fields

Message

The network adapter '%1' does not support a value of %4 for setting %2\%3. The closest adapter supported value of %5 will be used.

Fields

Message

A connection has been terminated because no pending requests to network adapter '%6' have completed in the last %7 milliseconds. Verify that the network is operational and that the peer is responsive. This event may also indicate that there are insufficient send credits to support the workload. Socket = %1 Local = %3 Remote = %5

Fields

Message

Settings BaseAffinityNode and MaxAffinityNode (\Registry\Machine\System\CurrentControlSet\Services\SmbDirect\Parameters) must specify a set of NUMA nodes that contain active processors. All of the system's processors will be eligible to perform SMB Direct processing until the error is corrected.

Fields

Message

A registry configuration parameter is invalid.RegistryKey: {RegistryKeyName}ParamName: {ParamName}ParamType: {ParamType}MinValue: {MinValidValue}MaxValue: {MaxValidValue}DefaultValue: {DefaultValue}Guidance:This event indicates that an administrator set an invalid configuration parameter value in the registry. Verify that the registry value is of the specified type and is in the range [MinValue; MaxValue]. The parameter's default value will be used until this issue is corrected. The SMB Direct driver must be restarted for the correction to take effect.

Fields

Message

Loaded a registry configuration parameter value.RegistryKey: {RegistryKeyName}ParamName: {ParamName}ParamValue: {Value}Guidance:This event indicates that an administrator has overridden SMB Direct's default value for this configuration parameter.

Fields

Message

The network adapter's FRMR page count is incompatible with SMB Direct.AdapterAlias: {AdapterAlias}Guidance:This network adapter reported an FRMR page count of zero; indicating that it does not support Fast Register Memory Regions (FRMRs). Compatible network adapters are required to support FRMRs. SMB Direct cannot be used with this network adapter.

Fields

Message

A NUMA node has only one processor that may be used to process interrupts.NumaNode={NumaNode}ProcessorGroup={ProcessorGroup}Guidance:This event indicates that SMB Direct found a NUMA node with only one processor that may be used to process interrupts. This configuration will degrade the performance of any SMB Direct connections that are affinitized to this NUMA node. It is recommended to increase the number of available processors in this NUMA node by changing the BaseAffinityProcessor and/or MaxAffinityProcessor configuration parameters.

Fields

Message

Failed to load a configuration parameter from the registry.

Registry key: %1

Guidance:

Verify that the parameter's registry value type is correct and that the value is in the parameter's range of accepted values. SMB Direct will use the parameter's default value until this issue is corrected. SMB Direct must be restarted to read updated configuration parameter values from the registry.

Guidance:

A socket configuration parameter value is not supported by the socket's RDMA network adapter or is incompatible with one or more of the socket's other configuration parameter values. The selected value will be used until this issue is corrected.

Guidance:

This event is informational. No action is required.

Fields

Message

A NUMA node has too few completion queue processors for optimal performance.

Node number: %1
Base affinity node: %2
Max affinity node: %3
Base affinity processor: %4
Max affinity processor: %5
Processor affinity mask: %7

Guidance:

The configuration parameters BaseAffinityNode, MaxAffinityNode, BaseAffinityProcessor, MaxAffinityProcessor, and ProcessorAffinityMask specify the set of processors that SMB Direct may use for its completion queues. The current configuration values allow only one processor in the specified NUMA node to be used (non-NUMA systems are treated as NUMA systems with one node). This configuration will degrade the performance of any SMB Direct connection that is affinitized to this NUMA node. To correct this issue, increase the number of completion queue processors in this NUMA node to a multiple of two. SMB Direct must be restarted to read updated configuration parameter values from the registry.

Fields

Message

Failed to identify any completion queue processors.

Base affinity node: %1
Max affinity node: %2
Base affinity processor: %3
Max affinity processor: %4
Processor affinity mask: %6

Guidance:

The configuration parameters BaseAffinityNode, MaxAffinityNode, BaseAffinityProcessor, MaxAffinityProcessor, and ProcessorAffinityMask specify the set of processors that SMB Direct may use for its completion queues. The current configuration values exclude all processors from being used. This configuration is invalid. SMB Direct will use all processors until this issue is corrected. SMB Direct must be restarted to read updated configuration parameter values from the registry.

Guidance:

The Network Direct Kernel Provider Interface (NDKPI) is the API through which SMB Direct interacts with RDMA network adapters. This adapter advertises an NDKPI limit that is incompatible with SMB Direct requirements. Contact the network adapter's manufacturer to determine if the limit can be increased.

Message

An RDMA network adapter's completion queue has experienced a catastrophic failure and is no longer operational.

Adapter interface index: %1
Socket ID: %2
Status: %3

Guidance:

RDMA capable network adapters use completion queues to notify SMB Direct that operations such as sending or receiving data have completed. The catastrophic failure of a completion queue will result in an unusable SMB Direct connection. Verify that the latest version of the network adapter's driver and/or firmware are installed. Contact the network adapter's manufacturer if the issue persists.
