HPE Performance Cluster Management Foundations - H8PE8S

Beschreibung

The HPE Performance Cluster Manager (HPCM) Foundations course provides knowledge and practice in cluster operation areas such as navigating the HPCM graphical user interface (GUI), monitoring cluster components, operating system boot modes and root filesystem modes, cluster power management, running commands on multiple servers, connecting to server consoles, and backing up the cluster configuration.

After you successfully complete this course, expect to be able to:
  •  Describe cluster components
  • Navigate HPCM GUI
  • Use operating system boot modes and root file system modes
  • Manage power with graphical and command line options
  • Gather information from groups of servers
  • Send instructions to groups of servers
  • Compare differences between servers
  • Connect server consoles with graphical and command line options 
  • Backup cluster and management switch configuration
  • Backup the system admin node with your house solution

    • Describe output, interleaved stdout, stderr
    • Review predefined pdsh node groups
    • Add a pdsh node group 
    • Run a command with the new pdsh node group
    • Run a command using the exclude node group format 
    • Format output from pdsh commands with dshbak –c
    • Copy a file to all compute nodes, to all leader nodes, to all ice-compute nodes,
    • Retrieve a file from all compute nodes, from all leader nodes, from all ice-compute nodes

    CLI Power commands
    • Use the cm power command to  – Check the power status of the cluster 
                          – Power on the cluster 
                          – Power off the cluster
                          – Power on or off individual and groups of nodes
                          – Turn on and off node identify LEDs

    CLI Console Feature
