Multipathing Software Overview
Multipathing software enables you to define and control redundant physical paths to I/O
devices such as storage devices and network interfaces. If the active path to a device becomes
unavailable, the software can automatically switch to an alternate path to maintain availability.
This capability is known as automatic failover. To take advantage of multipathing capabilities,
you must configure the server with redundant hardware, such as redundant network interfaces
or two host bus adapters connected to the same dual-ported storage array.
For the servers, three different types of multipathing software are available:

capabilities for IP network interfaces. This software includes commands and other software
