摘要： A method to dynamically adjust the amount of free space in a storage group is disclosed herein. In certain embodiments, such a method may include monitoring the amount of free space in an active storage group. The method may further include maintaining an overflow storage group containing unused volumes. When the free space in the active storage group falls below a lower threshold value, the method may automatically move a volume from the overflow storage group to the active storage group. Conversely, when the free space in the active storage group exceeds an upper threshold value, the method may automatically transfer data from a volume in the active storage group to other volumes in the active storage group, and move the volume from the active storage group to the overflow storage group. A corresponding computer program product and apparatus are also disclosed herein.

摘要： Method embodiments for facilitating overflow storage of special data sets that reside on a single logical volume are provided. A virtual logical volume is created from unallocated memory units across a plurality of logical volumes in a volume group. The virtual logical volume appears the same as any one of the logical volumes in the volume group to an external client. Upon receipt of a special data set that must reside in a single logical volume, an attempt is first made to allocate the special data set to one of the logical volumes in the volume group. If that allocation attempt fails, the special data set is allocated to the virtual logical volume. The virtual logical volume may be created only upon the failure to allocate the special data set to one of the logical volumes, and may be destroyed if sufficient space in one of the logical volumes is freed up to transfer the special data set. Creation of the virtual logical volume may be reserved for only critical special data sets whose failure would result in a storage system outage.
摘要翻译：提供了用于促进驻留在单个逻辑卷上的特殊数据集的溢出存储的方法实施例。虚拟逻辑卷是通过卷组中多个逻辑卷的未分配内存单元创建的。虚拟逻辑卷与卷组中的任何一个逻辑卷显示为外部客户端相同。在收到必须驻留在单个逻辑卷中的特殊数据集之后，首先尝试将特殊数据集分配给卷组中的一个逻辑卷。如果分配尝试失败，则将特殊数据集分配给虚拟逻辑卷。只有在将特殊数据集分配给其中一个逻辑卷时，才能创建虚拟逻辑卷，并且如果其中一个逻辑卷中的足够空间被释放以传输特殊数据集，则可能会被破坏。虚拟逻辑卷的创建可能仅为关键的特殊数据集保留，这些特殊数据集的故障将导致存储系统中断。

摘要： Data is added to a data set to cause a growth in size of the data set, wherein the data set belongs to a storage group, and wherein the data set is comprised of extents. The data set is included into a new storage group, in response to determining that the growth in the size of the data set has caused a predetermined threshold for a size limit of the storage group to be exceeded.

A catalog locate is performed for each of a plurality of data sets on a base catalog structure (BCS), identifying a plurality of BCS entries. If a first BCS entry is cataloged incorrectly, the first BCS entry is designated to be re-cataloged. The plurality of BCS entries is compared with a plurality of volume table of contents and a plurality of VSAM volume data set (VTOC/VVDS) entries. If a second BCS entry found in the plurality of BCS entries is not found in the plurality of VTOC/VVDS entries, and the second BCS entry indicates that a data set associated with the second BCS entry is located on a volume, an attempt is made to vary on the volume.

摘要： Described are embodiments of an invention for allocating storage space in a storage system for critical data sets. The computing environment includes at least one server including a processor and memory. The server is coupled to storage. The memory further includes a storage manager including an allocation module and an alert module. The storage manager defines a common area for storing non-critical data sets and critical data sets in the storage group. The storage manager also defines a critical reserve area for storing only critical data sets in the first storage group. A predefined percentage of available storage space is reserved for the critical reserve area. The predefined percentage of available space is determined by comparing the available storage space within the critical reserve area to the storage space in the storage group. Upon allocating additional storage to the storage group, the allocation module allocates an amount of the additional storage space to the critical reserve area such that the predefined percentage of available storage space is maintained in the critical reserve area.
