Abstract:
A computational device receives a request to create a logical unit. In response to determining that adequate space is not available to create the logical unit in a first type of storage pool, a determination is made as to whether a first indicator is configured to allow borrowing of storage space from a second type of storage pool. In response to determining that the first indicator is configured to allow borrowing of storage space from the second type of storage pool, the logical unit is created in the second type of storage pool The logical unit is moved from the second type of storage pool to the first type of storage pool, in response to determining that free space that is adequate to store the logical unit has become available in the first type of storage pool.
