This item is applied only when Hitachi AMS2000 series, Hitachi SMS
series, or HUS100 series storage is used.
-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:
