PowerPath Configurations for Linux

Read this section if you are installing a Linux PowerPath configuration with a new or existing server and a new or existing, storage system. A new and existing server and a new and existing storage system are defined as follows:

new server - A server running Linux that is not connected to any storage system.

existing server - A server running Linux that is already connected to one or more storage systems.

new storage system - A CX300, CCX500, or CX700 storage system that has the factory default settings and has never been connected to a server.

existing storage system - A CX200, CX300, CX400, CX500, CX600, CX700, FC4500, or FC4700-Series storage system that is already connected to one or more servers and is in a Navisphere domain.

All CLARiiON storage systems connected to the server must be CX200, CX300, CX400, CX500, CX600, CX700, FC4500, or FC4700-Seriesstorage systems. If any other type of CLARiiON storage system is connected to the server, the server cannot run PowerPath.
