Embodiment Construction

[0024] In the following description, reference is made to the accompanying drawings which are a part hereof, and which illustrate several embodiments. It is understood that other embodiments may be utilized and structural and operational changes may be made.

[0025] In some implementations of simultaneous writes, if for any reason the current primary storage pool cannot contain the data being stored, the storage manager may attempt to store the data to the next storage pool in the storage hierarchy. The next storage pool can be a tape storage pool. Before starting to store data to the next storage pool, any resources currently allocated to the primary storage pool as well as the copy storage pool can be released before acquiring resources for the next storage pool to prevent deadlock on the resources. If the next storage pool also has a copy storage pool defined for simultaneous write purposes, then the associated resources will need to be acquired before data can be backed ...

Abstract

Provided are a method, system, and an article of manufacture, wherein resources corresponding to at least one copy pool are acquired, and wherein the at least one copy pool has been defined for a first primary storage pool of a storage hierarchy. The acquired resources are retained, in response to determining that data cannot be written to the first primary storage pool. The data is written to the at least one copy pool, in response to writing the data to a second primary storage pool of the storage hierarchy.

Description

technical field [0001] The present invention relates to a method, system and computer program for resource management of data storage services. Background technique [0002] A storage manager, such as the Tivoli Storage Manager (TSM) product sold by International Business Machines (IBM) Corporation, may be used to securely store and back up data (IBM, Tivoli, and Tivoli Storage Manager (TSM) are trademarks or registered trademarks of IBM Corporation ). The storage manager can execute on a storage management server (eg, TSM server) and ensures data integrity and provides the ability to protect business critical data in the event of hardware, software and environmental failures. The storage manager can maintain images of data and programs on tape cartridges or other storage media. The storage manager can be used to restore data and programs from tape cartridges or other storage media in the event of a system failure or other event that results in data loss. [0003] TSM can...
