For details on the conditions under which certain copy pair statuses can be changed and on how
to change the status of a copy pair by using the Change Pair Status wizard, see the Replication
Manager online Help.
6. From the Explorer menu, select Tasks, then select Tasks again to confirm that the task is completed.
7. Confirm the copy pair status was changed by viewing the list of volumes in the Hosts view or the
Storage view in Replication Manager.
From the list of volumes in the Hosts tree or the Storage Systems tree, view the current copy pair
status.
TIP:
To display the most recent SplitTime in Device Manager after performing operations on a Snapshot
or Fast Snap copy pair, you need to refresh the storage system information.
Data mobility
An administrator can obtain information required to see the operating status of storage resources and
optimize data placement.
About data mobility
The Mobility tab provides information required to see the operating status of storage resources and
optimize data placement.
To efficiently use a storage resource, use the Mobility tab to optimize the data arrangement. In the
Mobility tab, information used to determine whether the data arrangement is appropriate is collectively
displayed. In addition, you can use the Mobility tab to centrally perform operations regarding moving
data such as data migration. To use the Mobility tab, you must first register a Tiered Storage Manager
license. Using Mobility tab information, you can evaluate and analyze whether the hardware tiers
are being used appropriately and whether the volumes are providing the expected performance.
Based on these results, you can optimize data placement by migrating data and setting up a Smart
Tiers Software tiering policy (which specifies the hardware tiers in which volumes are to be placed).
After completing these operations, check their effect from the Mobility tab and then perform any other
necessary data optimization operations. By repeating this process, the placement of data can be
optimized. The following figure shows the process of optimizing data placement.
From the Mobility tab, data placement can be optimized from either the application (logical group)
perspective or from the THP/Smart pool perspective. To respond to requests from host or application
administrators, or to confirm whether Smart pools and storage resources are being used according
to the needs of each application, check the balance between the performance and the configuration
ratio of logical groups. To regularly monitor storage resources, or if there is a problem in the analysis
of logical groups, check the balance between the performance and the configuration ratio of each
THP/Smart pool. If there is a problem, you must check the operating status of each volume in the
THP/Smart pool and then optimize the configuration.
