A.2 Using the disaster recovery function for large-scale disaster management
Disaster recovery refers to measures that are taken for unexpected events such as system shutdown caused by a large-scale disaster.
Normally, JP1/AJS3 information stored in the shared disk is copied to the shared disk of the system provided at a remote site. In the case of an emergency, such as a disaster, operation is switched over to the system on the remote site, and the applications are resumed there. Using the disaster recovery function prevents applications from being interrupted by a disaster, thus improving availability of the application system.
Use the disk copy and mirroring functionality in the hardware to copy data between shared disks. This is not a function of JP1/AJS3.
