-lb {on [-lbtype {rr|exrr|lio|exlio|lbk|exlbk}]|off}
Enables or disables load balancing.
on: Enabled
off: Disabled
-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 HDLM manager log (dlmmgr[1-16].log) contains log files in which an
error log collection level can be set.
Table 6-3 Values of the Error Log Collection Levels on page 6-17
shows
the values of the error log collection level. If an error occurs, you may
have to set the error log collection level to 1 or higher to collect log
information.
Table 6-3 Values of the Error Log Collection Levels

Description
0
Collects no error log.
