NAME

       ipmctl-show-topology - 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-dimm 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 DDR 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 module installed in the host server.

       MemoryType
           (Default) The DIMM type. One of:

           •   Unknown

           •   DDR4

           •   DDR5

           •   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.
