摘要： Provided are techniques for spare device management. Candidate devices are sorted into spare coverage groups by type. One or more candidate devices having closest fitting characteristics of a desired type are identified from the spare coverage groups. The identified one or more candidate devices are assigned to be spare devices for the spare coverage group. It is determined whether a desired number of spare devices have been assigned to the spare coverage group. In response to determining that the desired number of spare devices have not been assigned, a spare device having the closest fitting characteristics for every predetermined number of candidate devices having the closest fitting characteristics is assigned, until the desired number of spare devices having the closest fitting characteristics are assigned.

摘要： Provided are a method, system, and article of manufacture for relocating a logical volume from a first storage location to a second storage location using a copy relationship. An operation is initiated to move a logical volume from a first storage location to a second storage location. A relationship is established between the first and second storage locations to copy data in the logical volume from the first storage location to the second storage location. A read request is received to data in the logical volume while copying the data in the logical volume from the first storage location to the second storage location. A determination is made, in response to the read request, whether the requested data is at a first copy of the logical volume in the first storage location or a second copy of the logical volume as the second storage location. The requested data is returned from the determined first or second copy of the logical volume while the logical volume is being copied from the first storage location to the second storage location.

摘要： An apparatus, system, and method are disclosed for preventing write starvation in a storage controller with access to low performance storage devices. A storage device allocation module is included to assign a storage device write cache limit for each storage device accessible to a storage controller. The storage device write cache limit comprises a maximum amount of write cache of the storage controller available to a storage device for a write operation. At least one storage device comprises a low performance storage device and a total amount of storage available to the storage devices comprises an amount greater than a total storage capacity of the write cache. A low performance write cache limit module is included to set a low performance write cache limit. The low performance write cache limit comprises an amount of write cache available for use by the at least one low performance storage device for a write operation. The amount of write cache available to the at least one low performance storage device comprises an amount less than the total storage capacity of the write cache.

摘要： Provided are a method, system, and article of manufacture, wherein a request is received for switching a logical volume from one state to another state, wherein the logical volume is in a mirrored state if data corresponding to the logical volume is mirrored from a first storage to a second storage, and wherein the logical volume is in a non-mirrored state if the data corresponding to the logical volume is not mirrored from the first storage to the second storage. A determination is made as to whether to perform the switching, in response to receiving the request.
