Displaying cluster configuration information

Use the mmlscluster command to display cluster configuration information.

For more information, see mmlscluster command.

Basic configuration information

To display basic cluster configuration information, enter the following command with no parameters:
mmlscluster
The command displays information like the following example:
GPFS cluster information
========================
  GPFS cluster name:         cluster1.kgn.ibm.com
  GPFS cluster id:           680681562214606028
  GPFS UID domain:           cluster1.kgn.ibm.com
  Remote shell command:      /usr/bin/ssh
  Remote file copy command:  /usr/bin/scp
  Repository type:           CCR

 Node  Daemon node name        IP address       Admin node name         Designation
--------------------------------------------------------------------------------------
   1   k164n04.kgn.ibm.com     198.117.68.68    k164n04.kgn.ibm.com     quorum
   2   k164n05.kgn.ibm.com     198.117.68.69    k164n05.kgn.ibm.com     quorum
   3   k164n06.kgn.ibm.com     198.117.68.70    k164sn06.kgn.ibm.com    quorum-manager
If the cluster uses a server-based repository, the command also displays the following information:
  • The primary GPFS cluster configuration server
  • The secondary GPFS cluster configuration server

Information about protocol nodes

To display information about the protocol nodes, enter the following command:
mmlscluster --ces
The command displays information like the following example:
GPFS cluster information
========================
GPFS cluster name: cluster1.kgn.ibm.com
GPFS cluster id: 4708497829760395040
