Defining a tiering subrule
To specify exceptions to a cloud or tape tiering storage rule, you can define one or more subrules.
About this task
- For example, a cloud tiering storage rule is defined to tier all of the data in a directory-container storage pool to cloud storage. However, some of the data is required for daily operations, so you want to keep that data on disk storage, from which restore operations are typically faster. You define a subrule for specific nodes or file spaces to keep the specified data on disk storage.
- For example, a tape tiering storage rule is defined to tier data from different client types by
using the tier-by-state option. However, you determine that the tier-by-age option is more
appropriate for one of the client types. You define a subrule only for nodes or file spaces of the
specified client type to apply the tier-by-age option. Data from all other clients will be tiered by
state.Tip: To learn about tiering options as they affect different client types, see Determining whether tiering is appropriate for your storage environment.
