mmlsconfig command

Displays the current configuration data for a GPFS™ cluster.

Synopsis

mmlsconfig [Attribute[,Attribute...]]

Availability

Available on all IBM Spectrum Scale™ editions.

Description

Use the mmlsconfig command to display the requested configuration attributes for a GPFS cluster. If no specific attributes are requested, the command displays all values that were set explicitly by the user. Depending on your configuration, additional information that is set by GPFS might be displayed. If a configuration attribute is not shown in the output of this command, the default value for that attribute, as documented in the mmchconfig command, is in effect.

Parameters

Attribute
Specifies the name of the attribute to be displayed. If an attribute has unique values that apply to only a subset of the nodes, the values are followed by the list of affected node names. You can specify more than one attribute in a comma-separated list.
Note: See the mmchconfig command for a list of supported attributes.

Exit status

0
Successful completion.
nonzero
A failure occurred.

Security

You must have root authority to run the mmlsconfig command.

The node on which the command is issued must be able to execute remote shell commands on any other node in the cluster. It must be able to do so without the use of a password and without producing any extraneous messages. For more information, see Requirements for administering a GPFS file system.
