Figure 4-1 Storage Tiers and Volumes Relationship
When you delete a storage domain, the storage tiers within the deleted storage domain are also deleted at the
same time. Volumes within the storage tiers and migration tasks that are related to the storage tiers are not
deleted, however.
When an operational targeted storage tier belongs to a storage domain that is being refreshed, you cannot
operate the storage tier. In addition, if the status of a migration task of an operation target storage tier, which is
specified as the migration target, is Active or Standby, you cannot delete the storage tier or change its
attribute information.
4-2 Storage Tier Operations
Storage tier operations include creating a storage tier, deleting a storage tier, referencing the list of storage
tiers, referencing properties of a storage tier, changing attribute information for a storage tier, and searching
volumes within a storage tier.
Only the System Administrator and Storage Administrator can create, change attribute information for a storage
tier, or delete a storage tier. The System Administrator, Storage Administrator, and Guests who have access
privileges can reference storage tiers.
If the storage domain containing the storage tier to be operated is currently refreshing, you cannot operate the
storage tier. In addition, you cannot create or delete a storage tier or change attribute information for a storage
tier while the status of a migration task is Active or standby.
There are two methods for creating a storage tier:
• Creating a storage tier by defining its name and filter conditions in advance.
See
4-3 Selecting a Storage Tier Object within a Storage Domain and Creating a Storage Tier.
• Searching volumes and then creating a storage tier from the search result
See
4-4 Creating a Storage Tier from the Search Result for Volumes within a Storage Domain.
For each storage tier, you can specify a storage tier name, filter conditions, and description of the storage
tier. The storage tier name must be unique within its storage domain. You can change the filter conditions
for a storage tier by changing the attribute information.
4-3 Creating a Storage Tier by Selecting Storage Tiers Object
from a Storage Domain
You can create a storage tier by selecting the Storage Tiers object from a storage domain. When using this
method, first determine the name of the storage tier, and then create the storage tier by specifying conditions
for filtering volumes.
To create a storage tier by selecting the Storage Tiers object from a storage domain:
1. In the navigation frame, select the Storage Tiers object.
The method frame displays the Create Storage Tier method.
2. Select the Create Storage Tier method.
The Create Storage Tier pop-up window displays as shown in Figure 4-2.
