mmlsconfig command
Displays the current configuration data for a GPFS cluster.
Synopsis
mmlsconfig [Attribute[,Attribute...]] [-Y]
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 an attribute to display with its value. If no name is specified, the
command displays a default list of attributes with their values. See Example 1.For descriptions of the attributes, see the topic mmchconfig command. The mmlsconfig command, which lists the values of attributes, and the mmchconfig command, which sets the values of attributes, use the same attribute names.Exception: To update the minimum release level, issue the mmchconfig command with the attribute release=LATEST. To display the value of the minimum release level, issue the mmlsconfig command with the minReleaseLevel parameter. For more information, see Minimum release level of a cluster and mmchconfig command.
- -Y
- Displays the command output in a parseable format with a colon (:) as a field
delimiter. Each column is described by a header.Note: Fields that have a colon (:) are encoded to prevent confusion. For the set of characters that might be encoded, see the command documentation of mmclidecode. Use the mmclidecode command to decode the field.
Exit status
- 0
- Successful completion.
- nonzero
- A failure occurred.
Security
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.
Examples
- To display the current configuration data for the GPFS
cluster that you are running on, issue this command:
The system displays information similar to the following example:mmlsconfig
Configuration data for cluster small.cluster: --------------------------------------------- myNodeConfigNumber 1 clusterName small.cluster clusterId 6339012640885012929 autoload yes minReleaseLevel 4.2.0.0 dmapiFileHandleSize 32 [c6f1c3vp3] pagepool 512M [common] adminMode central File systems in cluster small.cluster: -------------------------------------- /dev/fs1 /dev/gpfs1
- To display the current values for the maxblocksize and
pagepool attributes, issue the following command:
mmlsconfig maxblocksize,pagepool
The system displays information similar to the following example:maxblocksize 4M pagepool 1G pagepool 512M [c6f1c3vp3]
- To display the current value for the cipherList attribute,
issue this command:
The system displays information similar to the following example:mmlsconfig cipherList
cipherList AUTHONLY
