Chapter 7 Operation of Performance Optimization Function (CLI)
The following shows examples of specifying the iSMprfctl command:
Example 1: Move data between the logical disk 000ah and the Work Disk for Optimization 0010h. Select the
iSMprfctl start_ldmv -arrayname NECStorage3100/10 -ldn ah -wkldn 10h
Example 2: Move data between the logical disk 000ah and the Work Disk for Optimization 0010h. Select the
iSMprfctl start_ldmv -arrayname NECStorage3100/10 -ldn ah -wkldn 10h -speed
high
Example 3: Specify a volume name to move data between the logical disk 000ah and the Work Disk for
iSMprfctl start_ldmv -arrayname NECStorage3100/10 -ldname NX:VOL000a -wkldname
NX:WK0010
Example 4: Specify a volume name to move data between the logical disk 000ah and the Work Disk for
iSMprfctl start_ldmv -arrayname NECStorage3100/10 -ldname VOL000a -wkldname
WK0010
(2) Confirmation of movement
The start_ldmv function of the iSMprfctl command starts moving a logical disk. This
command does not wait until moving of the logical disk is completed.
If having moved a logical disk by executing the command, confirm the start and completion of moving by the
following methods:
Start of movement
Make sure of the message for the iSMprfctl command and the NEC Storage PerformanceOptimizer message
that is output to the iSM operation log. When the logical disk starts moving normally, the following messages
are output:
Message for the iSMprfctl command:
Message output to the iSM operation log:
Completion of movement
Make sure of the NEC Storage PerformanceOptimizer message that is output to the iSM operation log.
Message output to the iSM operation log:
default volume movement speed (auto).
maximum data transfer rate (high) as the volume movement speed.
Optimization 0010h. Select the default volume movement speed (auto).
