2
6 ipmctl-delete-pcd - Clears select partition data from the PCD
7
9 ipmctl delete [OPTIONS] -pcd [TARGETS]
10
12 When Config is specified, the Current, Input, and Output Data Size and
13 Start Offset values in the Configuration header are set to zero, making
14 those tables invalid.
15 Note
17 When Config is specified, only PCD partition 1 is modified. If the
18 platform is rebooted prior to creating a new goal on any targeted
19 PMem modules, UEFI platform firmware will detect the missing tables
20 and, if possible, restore previous config using the PCD partition 0
21 tables.
22 Note
24 This action can be useful when moving PMem modules from one system
25 to another, as goal creation rules may restrict provisioning PMem
26 modules with an existing configuration. Deleting the PCD can be
27 used as a way to prepare a PMem module for provisioning with the
28 create -goal or load -goal commands by clearing existing
29 configuration metadata. This allows the PMem module to be
30 provisioned in isolation using the create-goal command with the
31 -dimm option. Once the PCD has been deleted the desired goal should
32 be created before rebooting.
33 Warning
35 This command may result in data loss. Data should be backed up to
36 other storage before executing this command. Because of data
37 dependencies, other commands may be affected until the system has
38 been rebooted.
39
41 -f, -force
42 Deleting the PCD data is a destructive operation which requires
43 confirmation from the user for each PMem module. This option
44 suppresses the confirmation.
45 -h, -help
47 Displays help for the command.
48 -ddrt
50 Used to specify DDRT as the desired transport protocol for the
51 current invocation of ipmctl.
52 -smbus
54 Used to specify SMBUS as the desired transport protocol for the
55 current invocation of ipmctl.
56 Note
58 The -ddrt and -smbus options are mutually exclusive and may not be
59 used together.
60 -lpmb
62 Used to specify large transport payload size for the current
63 invocation of ipmctl.
64 -spmb
66 Used to specify small transport payload size for the current
67 invocation of ipmctl.
68 Note
70 The -lpmb and -spmb options are mutually exclusive and may not be
71 used together.
72 -o (text|nvmxml), -output (text|nvmxml)
74 Changes the output format. One of: "text" (default) or "nvmxml".
75
77 -dimm [DimmIDs]
78 Deletes the PCD data on specific PMem modules by supplying one or
79 more comma separated PMem module identifiers. The default is to
80 delete the PCD data for all manageable PMem modules.
81 -pcd [Config]
83 Clears the configuration management information.
84
86 Clears the Cin, Cout, Ccur tables from all manageable PMem modules
87 delete -dimm -pcd Config
89
91 The specified PMem modules must be manageable by the host software, and
92 if data-at-rest security is enabled, the PMem modules must be unlocked.
93 Any existing namespaces associated with the requested PMem modules
94 should be deleted before running this command.
95
97 For each PMem module, the CLI will indicate the status of the
98 operation. If a failure occurs when deleting the platform configuration
99 data from multiple PMem modules, the process will continue deleting the
100 remaining PMem modules.
