Abstract:
1. A method, comprising: configuring at least two primary storage pools, wherein a first primary storage pool is configured to indicate a second primary storage pool as a next storage pool in a storage hierarchy that comprises the first primary storage pool and the second primary storage pool; copying the first primary storage pool of the storage hierarchy to a single copy storage pool, wherein the first primary storage pool and the single copy storage pool are included as parameters of a single command; determining whether a parameter associated with the single command is set to indicate that all primary storage pools in the storage hierarchy are to be copied to the single copy storage pool; in response to determining that the parameter associated with the single command is set to indicate that all primary storage pools in the storage hierarchy are to be copied to the single copy storage pool, copying the second primary storage pool to the single copy storage pool; and in response to determining that the parameter associated with the single command is not set to indicate that all primary storage pools in the storage hierarchy are to be copied to the single copy storage pool, avoiding copying the second primary storage pool to the single copy storage pool.
