Abstract
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.
Claims21
1-20. (canceled)
A method for mitigating disaster recovery in virtual tape applications, comprising:
- receiving, by a first virtual tape solution (VTS), a configuration override instruction from a first mainframe;
- obtaining, in response to the receiving, a disaster recovery configuration (DRC) from a configurations repository, wherein the DRC is a latest global configuration implemented on a second VTS prior to a failover event occurring on a second mainframe;
- and
- processing the DRC to configure a set of virtual tape engines (VTEs) of the first VTS, wherein, for each VTE of the set of VTEs, processing the DRC comprises:
- segmenting a portion of the DRC to define a VTE specific configuration (VSC).
A system, comprising:
- a first mainframe;
- a set of virtual tape engines (VTEs) operatively connected to the first mainframe;
- and
- a first disaster recovery manager (DRM) operatively connected to the first mainframe, and programmed to:
- receive, by a first virtual tape solution (VTS), a configuration override instruction from the first mainframe;
- obtain, in response to the receiving, a disaster recovery configuration (DRC) from a configurations repository, wherein the DRC is a latest global configuration implemented on a second VTS prior to a failover event occurring on a second mainframe;
- and
- process the DRC to configure the set of VTEs, wherein, for each VTE of the set of VTEs, processing the DRC comprises:
- segment a portion of the DRC to define a VTE specific configuration (VSC).
A non-transitory computer readable medium comprising instructions which, when executed by a computer processor, enables the computer processor to perform a method for mitigating disaster recovery in virtual tape applications, the method comprising:
- receiving, by a first virtual tape solution (VTS), a configuration override instruction from a first mainframe;
- obtaining, in response to the receiving, a disaster recovery configuration (DRC) from a configurations repository, wherein the DRC is a latest global configuration implemented on a second VTS prior to a failover event occurring on a second mainframe;
- and
- processing the DRC to configure a set of virtual tape engines (VTEs) of the first VTS, wherein, for each VTE of the set of VTEs, processing the DRC comprises:
- segmenting a portion of the DRC to define a VTE specific configuration (VSC).
