ipmctl-delete-pcd - Clears select partition data from the PCD
ipmctl delete [OPTIONS] -pcd [TARGETS]
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.
When Config is specified, only PCD partition 1 is modified. If the
platform is rebooted
prior to creating a new goal on any targeted PMem modules, UEFI platform firmware will detect the missing tables and, if possible, restore previous config using the PCD partition 0 tables.
This action can be useful when moving PMem modules from one system
to another, as goal creation
rules may restrict provisioning PMem modules with an existing configuration. Deleting the PCD can be used as a way to prepare a PMem module for provisioning with the create -goal or load -goal commands by clearing existing configuration metadata. This allows the PMem module 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.
This command may result in data loss. Data should be backed
to other storage before executing this command. Because of data dependencies, other commands may be affected until the system has been rebooted.
The -ddrt and -smbus options are mutually exclusive and may not be used together.
The -lpmb and -spmb options are mutually exclusive and may not be used together.
-o (text|nvmxml), -output (text|nvmxml)
Clears the Cin, Cout, Ccur tables from all manageable PMem modules
delete -dimm -pcd Config
The specified PMem modules must be manageable by the host software, and if data-at-rest security is enabled, the PMem modules must be unlocked. Any existing namespaces associated with the requested PMem modules should be deleted before running this command.
For each PMem module, the CLI will indicate the status of the operation. If a failure occurs when deleting the platform configuration data from multiple PMem modules, the process will continue deleting the remaining PMem modules.
