I have work to do to install new paths in for multipath and I was asked if there could be an outage as a result of my work. I struggled to answer the question. Simply adding new aliases to multipath.conf and restarting the service should be no impact or outage.
However if I was to remove existing aliases in the multipath.conf file and restarted the service I am unsure what how the application would react to this change.
If the application is a database and is presented with the alias of the disk from multipath, does it use the alias all the time or will it translate that into the uuid. How would a database like Oracle react to removing or resetting the multipath.conf file to defaults.
