Appendix A Commands of Performance Monitoring/Optimization Function
-ldn Logical disk number of the move-source logical disk
Specify the logical disk number of the logical disk to be moved. If the logical disk number is
specified with "h" suffixed, it is processed as a hexadecimal number. With "h" being omitted, it
is processed as a decimal number.
-ldname Nickname of the move-source logical disk
Specify the nickname of the logical disk to be moved in the format below.
[volume-format (up to 8 characters):] logical-disk-name (up to 24 characters)
To specify a logical disk for which a volume format has not been set, specify only ":" for
volume-format. Specification of a volume format can be omitted. However, if it is omitted and
the disk array contains a logical disk of the same name, iSMprfctl terminates abnormally.
-wkldn Logical disk number of the work disk for optimization
Specify the logical disk number of the work disk for optimization. The specification method is
the same as for the -ldn option.
-wkldname Nickname of the work disk for optimization
Specify the nickname of the work disk for optimization. The specification method is the same as
for the -ldname option.
-speed LD movement speed
Specify the speed at which data is copied when the logical disk is moved.
auto
high
[ RETURN VALUE ]
The iSMprfctl command returns either of the following values when it terminates:
0: Normal termination
1: Abnormal termination
[ DIAGNOSTICS ]
When the iSMprfctl command has terminated normally, it outputs a message, indicating the normal
termination, to the standard output file. When it has terminated abnormally, it outputs an error
message to the standard error output file.
The disk array automatically adjusts the LD movement speed in accordance with the load state.
Selecting auto minimizes influence on the business system. auto is the default of -speed.
Data is copied at the maximum transfer rate. Selecting high makes the moving time shorter
than when auto is selected, but increases a load on the business system. Select max in a
special case like when you want to give higher priority to tuning than business operation.
