Recovering CA Vtape Subsystem › Recover at the Disaster Recovery Data Center

Recover at the Disaster Recovery Data Center

The recovery process restores the CA Vtape control data sets and the tape management system back to the point in time when the last available backup was created. The following elements must be available at the disaster recovery location:

• Access to replicated networked devices containing Virtual Volume files.
• A Linux Server with the CA Cloud connector installed and properly configured.
• Latest copy of the backups that are performed at the PDC. See Prepare for Disaster Recovery.

Follow these steps:

1. Restore the product libraries and the parmlib.
2. Define and initialize the Local VCAT by submitting job DEFVCAT located in HLQ.CCUUJCL.

   Note: The SVTPARMS DD must reference a data set that contains an SUTPARMS member. The SUTPARMS member must contain the CA Vtape DSN prefix and Virtual Volume Size information that is used to configure the PDC installation.

3. Restore the BSDS and perform all the steps in the section Recover the Global VCAT.
4. Verify that the SVTS JCL procedure is located in your DRC proclib. If not, copy it from HLQ.CCUUPROC and customize it.
5. Review the OSDRIVE parmlib member and verify that the Virtual Device addresses conform to the ones defined at the DRC.
6. Review the OSPOOLS parmlib=b member and ensure that it is configured correctly for your DR requirements.

   For example, you can edit the member and can move the VOLSER ranges defined in Pool1-7 to Pool8. The VOLSER ranges in Pool8 may need to be moved to Pool1-7. This reserves volser ranges for DR recovery. Volser ranges that are placed in Pool8 are not used for scratch mount requests.

7. Review the OSPARMS parmlib member and verify that the PipeUnitAddress attribute addresses conform to the ones defined for the CA Cloud Connector DR location.
8. If the CA Cloud Connector is not installed, download it and install the cacloud and ctcl rpms on your Linux for System z system.
9. Start the CA Cloud Storage for System z setup tool by issuing the command:

   cacloud setup
   

10. Select CONFIG from the Main Menu, and page down to the CTC definitions. If needed, update the definitions to match the definitions that are defined at the DRC.
11. Save your changes and leave the editor.
12. Select QUIT from the Main Menu to leave Setup.
13. Start the Linux Server by issuing the command:

    cacloud start
    

14. Start CA Vtape by issuing the command:

    S SVTSCE
    

15. Restore the tape management system catalog.
16. You can now submit jobs requiring Virtual Volumes.
