NAME

       ipmctl-delete-pcd - Clears select partition data from the PCD

SYNOPSIS

       ipmctl delete [OPTIONS] -pcd [TARGETS]

DESCRIPTION

       When Config is specified, the Current, Input, and Output Data Size and Start Offset values in the
       Configuration header are set to zero, making those tables invalid.

           Note
           When Config is specified, only PCD partition 1 is modified. If the platform is rebooted prior to
           creating a new goal on any targeted DCPMMs, UEFI platform firmware will detect the missing tables
           and, if possible, restore previous config using the PCD partition 0 tables.

           Note
           This action can be useful when moving DCPMMs from one system to another, as goal creation rules may
           restrict provisioning dimms with an existing configuration. Deleting the PCD can be used as a way to
           prepare a DCPMM for provisioning with the create -goal or load -goal commands by clearing existing
           configuration metadata. This allows the DCPMM to be provisioned in isolation using the create-goal
           command with the -dimm option. Once the PCD has been deleted the desired goal should be created
           before rebooting.

           Warning
           This command may result in data loss. Data should be backed up to other storage before executing this
           command. Because of data dependencies, other commands may be affected until the system has been
           rebooted.

OPTIONS

       -f, -force
           Deleting the PCD data is a destructive operation which requires confirmation from the user for each
           DCPMM. This option suppresses the confirmation.

       -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.

       -lpmb
           Used to specify large transport payload size for the current invocation of ipmctl.

       -spmb
           Used to specify small transport payload size for the current invocation of ipmctl.

           Note
           The -lpmb and -spmb 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]
           Deletes the PCD data on specific DCPMMs by supplying one or more comma-separated DCPMM identifiers.
           The default is to delete the PCD data for all manageable DCPMMs.

       -pcd [Config]
           Clears the configuration management information

EXAMPLES

       Clears the Cin, Cout, Ccur tables from all manageable DCPMMs

       delete -dimm -pcd Config

LIMITATIONS

       The specified DCPMM(s) must be manageable by the host software, and if data-at-rest security is enabled,
       the DCPMMs must be unlocked. Any existing namespaces associated with the requested DCPMM(s) should be
       deleted before running this command.

RETURN DATA

       For each DCPMM, the CLI will indicate the status of the operation. If a failure occurs when deleting the
       platform configuration data from multiple DCPMMs, the process will continue deleting the remaining
       DCPMMs.
