SMS series, Universal Storage Platform V/VM, Virtual Storage Platform, 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 2.14 Cluster Support.
-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:
dlmmgr
n
.log
(n indicates a file number from
1
to
16
)
HDLM GUI logs:
dlmgui
n
.log
(n indicates a file number of
1
or
2
)
Table 6-3: Values of the Error Log Collection Level 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 Level
Value Description
0
Collects no error log.
1
Collects error information for the Error or higher level.
