•
After a data placement profile has been applied and monitoring and data relocation of Smart
pools has been performed, a data placement is restored. Therefore, users need to determine the
timing at which to apply a profile by taking into account the period during which the monitoring
and data relocation are performed.
•
When performing a create, update, apply, or release of a data placement profile, or when
searching for or repairing an inconsistency in a data placement profile, users cannot perform
other operations for the target storage system.
•
A task to create, update, apply, or release a data placement profile or to search for or repair an
inconsistency in a data placement profile takes time to complete after it is executed. This time
might affect other operations, so make a plan based on the displayed time estimate. Keep in mind
that the larger the number of target volumes, the more likely that the estimated time and the actual
execution time will differ greatly. You can also stop tasks that are being executed, and then restart
them.
•
Regardless of the allocated resource groups, data placement profiles created by another user can
also referenced in the list of profiles. However, operation that can be performed on such profiles
are restricted based on the allocated resource group and role.
•
If the number of managed data placement profiles exceeds 200, displaying the profile list might
take some time. In this case, set the [Rows/page] of the profile list to no more than 100.
•
When the operations listed below are performed, users need to perform a search inconsistency
operation from the Refresh Storage Systems dialog because the profile that is actually applied to
the volume in a storage system might not match the profile information that can be referenced
from HP StorageWorks P9000 Command View Advanced Edition Suite.
• When the HP StorageWorks P9000 Command View Advanced Edition Suite database was
overwritten, due to an import or restoration, while the applied profile existed.
• When the storage system that contains an applied profile is deleted, and the storage system
is re-registered.
TIP:
If inconsistencies are detected, a message will be displayed in Manage Data Placement Profiles dialog.
From the link shown in the message, perform the
repair inconsistencies
operation and
release the profile. This can avoid unintended data to be fixed into a high-speed hardware tier by a
profile that was applied in the past.

Creating a data placement profile for Smart volumes
To restore a data replacement appropriate for application processing, the user creates a data placement
profile when Smart volumes provide sufficient performance. A profile can be created for each logical
group, and is managed with the corresponding logical group.
Prerequisites
Perform the following tasks beforehand:
•
A Tiered Storage Manager license must be registered
•
Acquire the name of the target logical group
