-lb {on [-lbtype {rr|exrr|lio|exlio|lbk|exlbk}]|off}

Enables or disables load balancing.
on: Enabled
off: Disabled
In a cluster environment, the load balancing function is only available for

the Thunder 9500V series, Lightning 9900V series, Hitachi USP series,

Hitachi AMS2000/AMS/WMS/SMS series, HUS100 series, Universal

Storage Platform V/VM series, and Virtual Storage Platform series. In a

non-cluster environment, the load balancing function is available for the

Thunder 9500V series, Lightning 9900V series, Hitachi USP series, Hitachi

AMS2000/AMS/WMS/SMS series, HUS100 series, Universal Storage

Platform V/VM series, Virtual Storage Platform series, and the EMC DMX

series. The conditions mentioned above will be used no matter what for

the settings for the EMC DMX series, EMC CX series, and HP EVA series.

For example, in a cluster environment, the load balancing function is

disabled even if it is set to on for the EMC DMX series. For details on the

cluster software supported by HDLM, see

Cluster Support on page 2-46

.

-lbtype {rr|exrr|lio|exlio|lbk|exlbk}

Specify the algorithm to be used for load balancing.
rr: The Round Robin algorithm
exrr: The Extended Round Robin algorithm
lio: The Least I/Os algorithm
exlio: The Extended Least I/Os algorithm
lbk: The Least Blocks algorithm
exlbk: The Extended Least Blocks algorithm
The type of algorithm specified by the -lbtype parameter remains

stored in the system, even when you disable the load balancing

function by specifying -lb off. Therefore, if you re-enable the load

balancing function without specifying an algorithm, load balancing will

be performed according to the algorithm that is stored in the system.

-ellv error-log-collection-level

Specify the level of error information you want to collect for an error log.
The following shows the log files in which an error log collection level can

be set:
