No load balancing is performed. There is a single active path; the remaining pathsare standby paths. The active path sends all I/O. If the active path fails, a standby path is used.When the formerly active path is reconnected, it becomes active and the activated standby pathreturns to standby.• Round-robin. All paths are active paths and are used to send I/O in a round-robin fashion.• Round-robin with a subset of paths. One set of paths is configured as active and another set ofpaths is configured as standby. I/O is sent in a round-robin fashion over the active paths. If allactive paths fail, a standby path is used. When a formerly active path is reconnected, it becomesactive and the activated standby path returns to standby.• Weighted Path. Each path is assigned a weight and I/O is sent on the path with the lowest weight.If the path with the lowest weight fails, the path with the next lowest weight is used.• Least Queue Depth. This is not supported by MPIO.MPX200 iSCSI configuration rules and guidelines92
