HP XP P9500 Storage - Manual (Page 232)

Enables or disables load balancing.
on: Enabled
off: Disabled
Load balancing distributes load among paths and prevents the
performance of the entire system from deteriorating. As such, we
recommend that you set this parameter to on.
-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 when 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 Logging Level on page 6-20 shows the
values of the error logging 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 Logging Level
Value Description
0 Collects no error log.
1 Collects error information for the Error or higher level.
2 Collects error information for the Warning or higher level.
3 Collects error information for the Information or higher level.
4 Collects error information for the Information or higher level
(including maintenance information).
The higher the error log collection level value, the more log information
will be output. As the amount of log information that is output increases,
the amount of time before existing information will be overwritten
becomes shorter.
