Using Bidirectional Replication for Disaster Recovery › Test Configuration

Test Configuration

After you set up the two CA Vtape VTS systems in a bidirectional configuration, run tests to verify that Virtual Volumes are replicated and accessible between the primary and secondary appliances:

1. Run a job at the PDC that allocates a scratch Virtual Volume for a data set like PROD.TEST. CA Vtape VTS mounts a VOLSER in the P00000-P00999 range on the primary appliance. At some point after the tape is unmounted the disk storage appliance replicates the Virtual Volume to the secondary appliance.
2. After the Virtual Volume replication completes, run a job at the DRC that reads the VOLSER from the secondary appliance.
3. Submit the same job at the DRC. The job mounts a Virtual Volume in the D00000-D00999 range on the secondary appliance. At some point, after the tape is unmounted, the disk storage appliance replicates the Virtual Volume to the primary appliance.
4. Run a job at the PDC that reads the VOLSER from the primary appliance, after the Virtual Volume replication completes.

Note: If the user catalogs are not mirrored or shared between the systems, code the VOLSER in the JCL to mount it.
