Storage resource pools provides domain administrators the ability to manage storage attributes that are used to allocate data sets. Typically, the storage attributes are obtained from the variables input file. With storage resource pools, storage attributes can now be obtained dynamically from the storage resource pool using a workflow REST step. In order to use this function, middleware provisioning workflows needs to be updated to obtain the storage attributes using a new "Get data set attributes" REST API described in the z/OSMF Programming Guide.
Storage resource pool is an optional feature that can be created when creating a shared or dedicated resource pool. This allows for separation of storage resources to be either tenant or template scoped. Storage attributes from a shared resource pool are available to all templates associated with the shared resource pool. With dedicated resource pools, the storage attributes can be accessed only by the one template that is associated with it.
Storage resource pool entries can be updated by modifying the resource pool. The new values can be obtained dynamically from the workflow REST step without having to modify the variables input file.
The storage attributes are obtained from the storage administrator. The storage administrator defines the data set attributes for a specific group/team. These values are then provided to the domain administrator to create the storage resource pools.
Once the storage resource pool has been created, the template can access the storage resource pool using a workflow REST step. The workflow REST step calls the "Get data set attributes" REST API to obtain the storage attributes. This REST API is described in the z/OSMF Programming Guide. The REST step then maps the storage attributes to workflow variables which are available to the template when allocating data sets.
