You can change the following pair options:

  • Cache-fast-write (CFW)
  • Error level

Before you begin

  • You can change the pair options only for pairs in PAIR, PSUS, PSUE, HOLD, HOLDING, or HLDE status.

Procedure

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

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

  3. In the UR Pairs tab, select the pair whose options are to be changed.

  4. Click More Actions Edit Pair Options.

    NoteWhen you select multiple pairs on the UR Pairs tab, Edit Pair Options values may be blank because the selected pairs have different values.

    When you specify a value, it is set for all selected pairs.

  5. In the Edit Pair Options window, for Error Level, specify the system response if a failure occurs in the pair.

    • Mirror: Splits all pairs in the failed pair’s mirror. Mirror is the default.
    • LU: Splits only the pair that failed.

  6. Click Finish.

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