Configuring primary and secondary storage systems for UR

You associate the primary and secondary storage systems in the Universal Replicator relationship and define the remote paths between them in one procedure.

Before you begin

  • This procedure must be performed on both primary and secondary storage systems
  • The primary and secondary storage systems must already be configured for Universal Replicator operations. For details, see system requirements in the Universal Replicator User Guide
  • The data path must be set up. For details, see the chapter on planning the data path in the Universal Replicator User Guide
  • The port attributes on the primary and secondary storage systems must be configured for UR. For details, see Defining Fibre Channel or iSCSI port attributes .
  • The system’s serial number and model will be required during this procedure.
  • A path group ID will be required. This is a group of a maximum of remote paths. For details, see the Path Group item in system requirements in the Universal Replicator User Guide.

In CCI, use the raidcom add rcu command and the raidcom modify rcu command.

Procedure

  1. In the Explorer pane, expand the Storage Systems tree.

  2. Expand the target storage system tree, expand Replication, and click Remote Connections.

  3. In the Connections (To) tab, click Add Remote Connection.

  4. In the Add Remote Connection window, for Connection Type, select System.

  5. In the Remote Storage System area, for Model, select the secondary storage system model and number.

    • For VSP G1000, VSP G1500, and VSP F1500, select 7
    • For VSP, select 6
    • For USP V/VM, select 5
    • For HUS VM, select 19 (available only if Connection Type is System)
    • For VSP Gx00 models and VSP Fx00 models, select 18 (available only if Connection Type is System)
    NoteIf the current storage system is one of the VSP Gx00 models or VSP Fx00 models, VSP and USP V/VM are not supported as the remote storage system.

  6. For Serial Number, enter the secondary storage system serial numbers (five or six digits).

    NoteWhen using virtual storage machine volumes, make sure to specify the serial number of the physical storage system. The serial number of a virtual storage machine cannot be specified.

  7. For Path Group ID, select the ID (00-FF) for the path group you want to use. You can register 1 to 64 path group IDs for each storage system.

  8. For Minimum Number of Paths, select the lowest number of paths between the local storage system and remote storage system (range = 1 to 8). For UR, select 1. If the number drops below this setting, the primary storage system will split the pair.

  9. For Select Type, select the port type.

  10. Select the port used by the local storage system and the remote storage system. If you selected iSCSI for the port type, enter the IP address and the TCP port number of the port on the remote storage system. To add a path, click Add Path. You can add a maximum of eight paths.

    You can add and remove paths later as needed using the Add Remote Paths window. For instructions, see Configuring additional remote paths.

  11. Click Options to enter RIO MIH Time (remote I/O missing interrupt handler), which is the waiting time from when copy starts until when it ends.

    This value applies to the slots which received the request of copying data between storage systems. Exceeding the value causes the data transfer operation to be reported as failed by the system. Valid values range from 10 seconds to 100 seconds, and the default is 15 seconds.
    NoteThe recommended RIO MIH setting for a 3DC cascade configuration is 20 seconds.

  12. Click Finish.

  13. In the Confirm window, review the settings, enter a task name, and then click Apply.
