Adding an additional journal volume to an existing journal

You can add one additional journal volume to a journal. The additional volume is not used unless needed for maintenance or to replace the first journal volume. In the event of pair failure, the additional reserve journal volume allows you to reduce the time to recover a blocked journal volume.

Before you begin

  • Review the following:
    • In the Universal Replicator User Guide, see the topics on system requirements, planning journals, and planning journal volumes.
  • The journal’s mirror status must be Initial, Active, Stopped, Hold, Holding, or Hold(Failure).
  • The journal cannot be in use.
  • Pair operations involving the journal cannot be in progress.
  • Cache Residency Manager settings cannot be defined for the volumes.
  • Adding a reserve journal volume to a journal while remote copy is in progress causes only the journal data area to be used, but not the metadata area, because it is unavailable. To make the metadata area available in this case, split and resynchronize all pairs in the journal group.

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 Mirrors tab, select the Journal ID link for the journal you want to add journal volumes to.

  4. In the Journal Volumes tab, click Assign Journal Volumes.

  5. In the Assign Journal Volumes window, from the Unassigned Journal Volumes table, select the journal volume to be added to the journal, and then click Add. The selected journal volume moves to the Assigned Journal Volumes table.

    To remove a volume from the table, select the volume and click Remove.
    NoteOnly OPEN-V volumes are displayed in the Unassigned Journal Volumes table.

  6. Click Finish.

  7. In the Confirm window, review the settings and enter a task name in the Task Name box.

  8. Click Apply to save your settings to the system.
