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 9900 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 9900 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:
HDLM manager logs:
dlmmgrn.log (n indicates a file number from 1 to 16)
HDLM GUI logs:
dlmguin.log (n indicates a file number of 1 or 2)
Table 6-3 Values of the Error Log Collection Level on page 6-19
shows the values of the error log collection level. If an error occurs,
