This chapter will provide information on administering DM-Multipath on a running system.

5.1. Automatic Configuration File Generation with Multipath Helper

You can generate a basic configuration for multipath devices on Red Hat Enterprise Linux with the Multipath Helper application. The application gives you options to create multipath configurations with custom aliases, device blacklists, and settings for the characteristics of individual multipath devices. Upon completion, the application generates an installation script that includes the configuration parameters you selected and it provides a multipath.conf configuration file for review.
The Multipath Helper application can be found at https://access.redhat.com/labsinfo/multipathhelper.
