IPMCTL-CHANGE-DEVICE-PASSPHRASE(1) ipmctl IPMCTL-CHANGE-DEVICE-PASSPHRASE(1)

NAME

ipmctl-change-device-passphrase - Changes the security passphrase on DCPMM on supported OS

SYNOPSIS

ipmctl set [OPTIONS] -dimm [TARGETS] Passphrase=(string) NewPassphrase=(string)
ConfirmPassphrase=(string)

DESCRIPTION

Changes the security passphrase on one or more DCPMMs.


Note

This command is subject to OS Vendor (OSV) support. It will return "Not Supported."

OPTIONS

-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.

-master

Changes the master passphrase. Valid only if master passphrase is enabled on specified DCPMMs (see MasterPassphraseEnabled attribute in section [Show Device]).

-default

Use this option when the current master passphrase is set to the default value. Valid only if used along with the -master option. May not be combined with the Passphrase property.

-source (path)

File path to a local file containing the new passphrase (1-32 characters).


Note

The file does not need to contain the ConfirmPassphrase property

TARGETS

-dimm [DimmIDs]

Changes the passphrase on specific DCPMMs by supplying one or more comma separated DCPMM identifiers. However, this is not recommended as it may put the system in an undesirable state. The default is to change the passphrase on all manageable DCPMMs.

PROPERTIES

Passphrase

The current passphrase (1-32 characters). For better passphrase protection, specify an empty string (e.g., Passphrase="") to be prompted for the current passphrase or to use a file containing the passphrases with the source option.

NewPassphrase

The new passphrase (1-32 characters). For better passphrase protection, specify an empty string (e.g., NewPassphrase="") to be prompted for the passphrase or to use a file containing the passphrase with the source option.

ConfirmPassphrase

Confirmation of the new passphrase (1-32 character and must match NewPassphrase). For better passphrase protection, specify an empty string (e.g., ConfirmPassphrase="") to be prompted for the passphrase or to use a file containing the passphrase with the source option.

EXAMPLES

Changes the passphrase from mypassphrase to mynewpassphrase on all DCPMMs.

ipmctl set -dimm Passphrase=mypassphrase NewPassphrase=mynewpassphrase


 ConfirmPassphrase=mynewpassphrase

Changes the passphrase on all DCPMMs by having the CLI prompt for the current and new passphrases.

ipmctl set -dimm Passphrase="" NewPassphrase="" ConfirmPassphrase=""

Changes the passphrase on all DCPMMs by supplying the current and new passphrases from the specified file. In this example, the format of the file would be:

#ascii
Passphrase=myOldPassphrase
NewPassphrase=myNewPassphrase

ipmctl set -source passphrase.file -dimm Passphrase="" NewPassphrase=""
ConfirmPassphrase=""

Changes the default master passphrase to masterpassphrase on all DCPMMs.

ipmctl set -master -default -dimm NewPassphrase=masterpassphrase ConfirmPassphrase=
masterpassphrase

Changes the master passphrase from masterpassphrase to newmasterpassphrase on all DCPMMs.

ipmctl set -master -dimm Passphrase=masterpassphrase NewPassphrase=newmasterpassphrase
ConfirmPassphrase=newmasterpassphrase

LIMITATIONS

In order to successfully execute this command:

•The caller must have the appropriate privileges.

•The specified DCPMM must be manageable by the host software, have security enabled and not be in the "Frozen" or "Exceeded" lock states.

Command is subject to OS Vendor (OSV) support. If OSV does not provide support, command will return "Not Supported."

RETURN DATA

If empty strings are provided for the passphrase properties and the source option is not included, the user will be prompted (once for all DCPMM) to enter the current passphrase, then again for the new passphrase and then again to confirm the new passphrase as described below. The passphrase characters are hidden.

Current passphrase: ****

For each DIMM, the CLI will indicate the status of the passphrase change operation. If a failure occurs when updating the passphrase on multiple DCPMMs, the process will exit and not continue updating the remaining DCPMMs.

SAMPLE OUTPUT

Change passphrase on DIMM (DimmID): Success

Change passphrase on DIMM (DimmID): Error (Code)-(Description)
