4.4.4 Multipathing
IBM offers different multipath drivers that you can use with your DS5000 storage subsystem.
Only one of these drivers is required. Each driver offers multipath support, I/O load balancing,
and automatic path failover.
The multipath driver is a proxy for the real, physical-level HBA drivers. Each multipath driver
hides from the application the fact that there are redundant connections by creating a virtual
device. The application uses this virtual device, and the multipath driver will connect the
application to the correct physical path.
Note: Make sure to check the System Storage Interoperation Center found at the following
