A mechanism for disaster recovery configurations and management in virtual tape applications. Specifically, the introduction of an additional computer process executing at an active datacenter site and at another active (or alternatively, a standby) datacenter site permit: (i) the generation and management of global configurations implemented on the active datacenter site prior to the occurrence of a failover event; and (ii) the implementation of global configurations on the another active (or standby) datacenter site after the occurrence of the failover event.

Disaster recovery specific configurations, management, and application

A mechanism for transparent (or non-disruptive) virtual tape engines restart. Specifically, the disclosed mechanism entails preserving a pre-restart state prior to restarting a virtual tape engine, followed by restoring the pre-restart state after the restarting in order to achieve transparency.

Mechanism for transparent virtual tape engines restart

A mechanism for multiple coexisting configurations support in virtual tape applications. Specifically, the introduction of various additional computer processes facilitate the introduction or modification of user specific configurations on a virtual tape solution: (i) without requiring the shutdown and re-initialization of the virtual tape solution; and (ii) without compromising the performance of computing resources allocated towards the implementation of other user specific configurations already existing on the virtual tape solution.

Mechanism for multiple coexisting configurations support in virtual tape applications

A mechanism for non-disruptive virtual tape libraries configuration. Specifically, the introduction of various additional computer processes permit the configuration of a virtual tape library without requiring the shutdown and re-initialization of the host application on which the virtual tape library resides.

Mechanism for virtual tape libraries non-disruptive configuration

A mechanism for non-disruptive virtual tape drives removal and reconfiguration. Specifically, the introduction of various additional computer processes permit the removal and reconfiguration of a virtual tape drive without requiring the shutdown and re-initialization of the host application on which the virtual tape drive is being emulated.

Mechanism for non-disruptive virtual tape drives removal and reconfiguration

In one example, a method for managing data includes defining a policy concerning migration of a dataset, and the policy specifies a condition that the dataset is to be migrated from a first storage entity to a second storage entity after the passage of a length of time during which the dataset was not accessed. The policy is then associated with the dataset. Next, a determination is made as to whether the condition of the policy has been met, and when the condition of the policy has been met, the dataset is automatically migrated from the first storage entity to the second storage entity.

Heirarchical storage for virtual tapes

A mechanism for non-disruptive virtual tape libraries removal and reconfiguration. Specifically, the introduction of various additional computer processes permit the removal and reconfiguration of a virtual tape library without requiring the shutdown and re-initialization of the host application on which the virtual tape library resides.
