HP Insight Cluster Management Utility v7.1 User Guide

• Managing the system images stored by HP Insight CMU
• Configuring actions performed when a node status changes such as display a warning, execute
a command, or send an email
• Exporting the HP Insight CMU node list in a simple text file for reuse by other applications
• Importing nodes from a simple text file into the HP Insight CMU database
1.1.3 Compute node administration
The HP Insight CMU GUI and CLI enable you to perform actions on any number of selected compute
nodes. Tasks include:
• Halting
• Rebooting
• Booting and powering off, using the compute node management card
• Broadcasting a command to selected compute nodes, using a secure shell connection or a
management card connection
• Direct node connection by clicking a node to open a secure shell connection or a management
card connection
1.1.4 System disk replication
The HP Insight CMU GUI and CLI enable you to replicate a system disk image on any number of
selected compute nodes. Tasks include:
• Creating a new image (While backing up a compute node system disk, you can dynamically
choose which partitions to backup.)
• Replicating available images on any number of compute nodes in the cluster
• Managing as many different images as needed for different software stacks, different operating
systems, or different hardware
• Cloning from one to 4096 nodes at a time with a scalable algorithm which is reliable and
does not stop the entire cloning process if any nodes are broken
• Customizing reconfiguration scripts associated with each image to execute specific tasks on
compute nodes after cloning
