Register RFCF License

Overview

This function registers an RFCF License.

Remote File Copy Facility-EXtended (RFCF-EX) is a function that performs remote data backups between the main center (*1) and the backup center (*2) if operations cannot continue due to problems such as disasters. The ETERNUS DX8900 S4 supports "Remote Backup System (RBS) mode" that performs system duplication.

To use the Remote File Copy Facility-EXtended management (hereinafter referred to as "RFCF-EX management"), register the RFCF License to all the storage systems (*3) in the main center and in the backup center.

   *1  :  A source center that transfers data.
   *2  :  A destination center that receives data.
   *3  :  The number of RFCF Licenses that must be ordered is the same as the number of storage systems that perform RFCF-EX management.
Caution
  • RFCF-EX management is provided with the following conditions.

    • The ETERNUS DX8900 S4 supports this function. RFCF-EX management with the ETERNUS DX8100 S4 or older models is not supported.

    • F6427G, F6427H, and F6427K type volumes are supported. F6427P, F6427R, and MVV type volumes are not supported.

    • RFCF-EX management is not supported if DVCF management is used in the storage system.

    • RFCF-EX management and REC cannot be used in the same LCU.

    • Eight LCUs can be used for RFCF-EX management in the storage system. The number of remote storage systems per LCU is two.

How to configure RFCF-EX management

To perform RFCF-EX related settings and actions, the storage system must be rebooted after registering the license.

Perform the following procedure to configure RFCF-EX.

  1. Change the FC port mode to "RFCF-RA". Refer to the [Modify Port Mode] function for details.

  2. Select "Fabric" for "Connection" of the FC port that is changed in Step 1. Refer to the [Modify FC Port Parameters] function for details.

  3. Select "Enable" for "RBS Mode" of the LCU that is used for RFCF-EX management. Refer to the [Add LCU] function or the [Modify LCU] function for details.

  4. Set the RFCF priority. Refer to the [Setup RFCF Priority] function for details.

  5. Set the WWN of the remote RFCF-RA port to allow access from the local RFCF-RA port. Refer to the [Setup RFCF-RA WWN] function for details.

  6. Set an RFCF-RA path between the main center and the backup center. Refer to the [Setup RFCF-RA Path] function for details.

  7. Check the RFCF-RA path between the main center and the backup center. Refer to the [RFCF Settings] function for details.
