- Management mode versus Monitor-only mode

# Management mode versus Monitor-only mode

Contents

## What is Management Mode?

The Intel® Manager for Lustre* software lets you create and manage new HA Lustre file systems from its GUI. For each HA file system, the GUI and dashboard let you create, monitor, and manage all servers and their respective targets. The software lets you define failover servers to support HA. RAID-based fault tolerance for storage devices is implemented independent of Intel® Manager for Lustre* software.

To provide robust HA support, Intel® Manager for Lustre* software automatically configures Corosync and Pacemaker, and takes advantage of IPMI or PDUs to support server failover.

Note: Managed HA support requires that your entire storage system configuration and all interfaces be compliant with a pre-defined configuration. See the High Availability Configuration Specification in the Intel® Enterprise Edition of Lustre, Partner Installation Guide for detailed information.

Note: Management mode is supported in Intel® Enterprise Edition for Lustre* software, versions 1.0 and later. No claims of support are made for any versions of Lustre outside of that shipped with Intel® EE for Lustre* software.

## What is Monitor-only Mode?

Monitor-only mode allows you to “discover” an existing Lustre file system using Intel® Manager for Lustre* software. You can then monitor the file system at the Intel® Manager for Lustre* dashboard. All of the charts presented on the manager dashboard to monitor performance and statistics, are available in monitor-only mode.

Monitor-only mode can be used to establish monitoring for file systems that don’t fully conform to the High Availability Configuration Specification. In this situation, the Corosync and Pacemaker configuration modules provided with Intel® Manager for Lustre* software are not automatically deployed. This means that Intel® Manager for Lustre* software cannot configure the file system for server failover.

Note: RAID-based fault tolerance for storage devices are implemented independent of Intel® Manager for Lustre* software.
