Chapter 6 Operation of Performance Optimization Function (GUI)
II-41
Scheduled Movement
Displays only logical disks that are schedule to be moved.
The Movement Progress Information is updated according to the interval time specified in the environment
definition of the iSM. For the check interval, refer to Chapter 5 “Installation of Performance Optimization
Function”.
After completion of logical disk movement, the relation between the logical disk and the RANK changes. This
configuration change is detected by the iSM simultaneously with the completion of the transfer and is reflected on
the state monitoring screen of the iSM as well as on the NEC Storage PerformanceOptimizer screen.
(3) Exceptional
Operations
After the transfer of a logical disk has started or the movement schedule has registered, there is a possibility of
canceling the movement, changing the speed and changing (canceling) the movement schedule for some reason.
Canceling the movement
A wrong logical disk has been moved.
Changing the speed
The transfer speed will be changed to “high” because the disk has to be moved as soon as possible.
The speed setting will be changed to “auto” because the business system is greatly affected by the
maximum speed.
Changing (canceling) movement schedule
Due to circumstances that does not allow executing a move at a scheduled time, movement start time must
be changed or registered movement schedule must be canceled.
As described above, interrupting disk movement, changing movement speed, and changing (canceling) movement
schedule are unusual operations. For such exceptional operations, the screen allows interrupting disk movement,
changing movement speed, and changing (canceling) movement schedule. However, pay extra attention in
operations of interrupting disk movement, changing movement speed, and changing (canceling) movement
schedule. These operations are allowed for users of L2 level or higher only.
The following describes the procedures for stopping movement, changing movement speed, and changing
(canceling) movement schedule.
