(default).
off: Do not enable load
balancing.
Optional Optional 3
load_balance_type Specify the load balancing
algorithm by specifying either
of the following values:
rr: The Round Robin
algorithm
exrr: The Extended Round
Robin algorithm
lio: The Least I/Os algorithm

Optional Optional 5
load_balance_same
_path_use_times Specify the number of times
the same path can be used
for I/O operations when the
Round Robin (rr), Least I/Os
(lio), or Least Blocks (lbk)
algorithm is used for load
balancing.
You can specify a value from
0 to 999999. The default is 1.
Optional Optional 6
lbex_usetimes_lim
it Specify the number of times
the same path can be used
for sequential I/O operations
when the extended Round
