  • EMC PowerPath

问题

  • Is there a way to migrate from EMC PowerPath to device-mapper-multipath while the system is online and devices in use?

决议

Online migration from PowerPath to device-mapper-multipath is not possible.  Consult EMC's "Removing PowerPath from a Linux host" documentation to remove PowerPath, then ​​configure device-mapper-multipath​​ and create the maps.
