ipmctl-show-topology - Man Page

Shows the topology of the memory installed

Synopsis

ipmctl show [OPTIONS] -topology [TARGETS]

Description

Shows the topology of the memory installed in the host server. Use the command ipmctl-show-device to view more detailed information about a PMem module.

Options

-a, -all

Shows all attributes.

-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".

-u (B|MB|MiB|GB|GiB|TB| TiB), -units (B|MB|MiB|GB|GiB|TB| TiB)

Changes the units that capacities are displayed in for this command. One of: bytes (B), megabytes (MB), mebibytes (MiB), gigabytes (GB), gibibytes (GiB), terabytes (TB) or tebibytes (TiB).

Targets

-dimm [DimmIDs]

Restricts output to specific PMem modules by optionally supplying the PMem module target and one or more comma-separated PMem module identifiers. The default is to display all PMem modules.

-socket [SocketIDs]

Restricts output to the PMem modules installed on specific sockets by supplying the socket target and one or more comma-separated socket identifiers. The default is to display all sockets.

Note

If ACPI PMTT table is not present, then DDR4 memory will not be displayed in the filtered socket list.

Examples

Displays the system memory topology.

ipmctl show -topology

Return Data

Displays a table with the attributes listed below for each memory PMem module installed in the host server.

MemoryType

(Default) The DIMM type. One of:

  • Unknown
  • DDR4
  • Logical Non-volatile Device
Capacity

(Default) The raw capacity of the PMem module as reported in the SMBIOS Type 17 table.

DimmID

(Default) The DIMM identifier. For DRAM DIMMs, the DimmID is "N/A".

PhysicalID

(Default) The PMem module physical identifier (i.e., SMBIOS Type 17 handle).

DeviceLocator

(Default) The string that identifies the physically-labeled socket or board position where the PMem module is located.

SocketID

The processor socket identifier (i.e., NUMA node) where the PMem module is installed.

DieID

The processor die identifier where the PMem module is installed.

MemControllerID

The associated memory controller identifier.

ChannelID

The associated channel. For DRAM DIMMs, the channel identifier is "N/A".

ChannelPos

The PMem module position in the channel.

NodeControllerID

The node controller identifier.

BankLabel

The string that identifies the physically-labeled bank where the PMem module is located.
