Provided are a method, system, and computer program product in which operations are performed for generating a logical recovery cache partition to perform testing and to recover exported data, wherein production data is separated from recovered data. Concurrent recovery of exported physical tape data is performed by the method, system, and computer program product.

Concurrent recovery of exported physical tape data

A tool for adjusting available physical tape storage capacities. The tool determines an initial capacity size for one or more tapes, wherein the initial capacity size is a maximum physical storage capacity provided by the one or more tapes. The tool assigns the one or more tapes to a logical cluster based, at least in part, on the initial capacity size for the one or more tapes. The tool determines an initial storage capacity for the one or more tapes, wherein the initial storage capacity is a starting logical storage capacity that is less than the maximum physical storage capacity provided by the one or more tapes. The tool determines an incremental growth threshold for the one or more tapes. Responsive to a determination that the incremental growth threshold is exceeded, the tool increments a logical storage capacity of the one or more tapes by an incremental growth assignment.

Adjustable tape storage capacity

A method according to one embodiment includes copying data incoming to and/or generated at a production site to a copy cluster at a remote copy site, thereby creating a redundant copy of the data at the copy cluster. When the copy cluster becomes unavailable, data incoming to and/or generated at the production site is copied to a backup reserve site after the copy cluster becomes unavailable. Additional systems, methods, and computer programs products are also presented.

Apparatus, system and method for temporary copy policy

A computer identifies one or more program functions within program code of a computer program affected by a program code change. The computer identifies program function calls made by the one or more program functions to other program functions. The computer adds the one or more program functions and program function calls to a program code database. The computer generates a mapping of relationships between the program functions of the program code. The computer selects one or more test scripts based on the mapping of relationships.

Comprehensively testing functionality of a computer program based on program code changes

Provided are a computer program product, system, and method for selecting one of a plurality of scanner nodes to perform scan operations for an interface node receiving a file request. A list includes a plurality of scanner nodes in a network and for each scanner node a performance value. One of the scanner nodes in the list is selected based on the performance values of the scanner nodes and the file is transmitted to the selected scanner node to perform a scan operation with respect to the file. Indication is received from the selected scanner node performing the scan operation whether a subset of code in the file matches code in a definition set. The file request is processed to result in execution of the file request based on the indication of whether the subset of code in the file matches a definition in the definition set.

Selecting one of a plurality of scanner nodes to perform scan operations for an interface node receiving a file request

A portable data storage cartridge, comprising a housing and a data storage medium disposed within the housing. The portable data storage cartridge further comprises a first label reciting an identifier disposed on a front portion of the housing, and a second label displaying said identifier at one or more places disposed on a side portion of said housing. A plurality of portable data storage cartridges can be disposed in a storage slot dimensioned to accommodate (N) portable data storage cartridges in a row. The storage slot is formed to include (N&#x2212;1) visualization apertures extending through a side. In addition, the storage slot further comprises (N&#x2212;1) reflective members, where each reflective member comprises a first end attached to the side with a second end extending outwardly from that side.

Method and apparatus to inventory portable data storage cartridges disposed in a storage library

A preparation of a storage system of a pending disaster at an onsite location of the storage system involves the storage system receiving a disaster preparation initiation from an offsite client. In response to receiving the disaster preparation initiation from the offsite client, the storage system to executes disaster preparation of onsite data including managing a temporary storage of onsite data volumes to at least one peer site, managing a storage of onsite cached data to a first onsite removable media, and/or managing a storage of onsite management information to a second onsite removable media.

Method and system for insuring data integrity in anticipation of a disaster

An apparatus, system, and method are disclosed for archiving log data. In one embodiment, an allocation module allocates a plurality of log logical volumes in a storage pool for storing copies of log instances. The log logical volumes may be hidden from a user. A log module records log data to at least one first log instance in a cache. A copy module transparently copies the at least one first log instance to a first log logical volume of a plurality of log logical volumes in a storage pool when a copy policy is satisfied. The log module further records the log data to at least one second log instance in the cache, overwriting the at least one first log instance. In one embodiment, a selection module selects a second log logical volume of the plurality of log logical volumes to receive the copied at least one second log instance if the first log logical volume satisfies a wrap policy.
