Symptoms

Replication issues start on multiple RecoverPoint Systems using the same Unity array after creating a new Consistency Group (CG) or adding Journal Volumes on existing CGs.

From System (CLI) Events: 
  Topic:                GROUP
  Scope:                DETAILED
  Level:                ERROR
  Event ID:             4040
  Summary:              Journal error
  More information:     Full sweep to be performed.

  Topic:                GROUP

  Summary:              Journal available

  Topic:                GROUP
  Scope:                NORMAL
  Level:                WARNING
  Event ID:             4082
  Summary:              The dirtying action took place either due to a user action (e.g. group was enabled or journal volumes changed) or due to a system fatal error.
  There will be only one full sweep on this link in the next synchronization, regardless of the number of times the link's copies are marked as dirty until the synchronization starts.
  More information:     The copy marked all of its replication volumes as dirty.

Cause

This problem occurs when multiple RPAs from different RecoverPoint systems are writing to the same Journal Volumes.  When this occurs, the Journal history for both CGs becomes corrupted and initiates a full sweep to ensure data consistency. This also triggers the Replication process restarts which lead to Reboot Regulation on the RPAs.

Resolution

Resolution:
Ensure that each Consistency Group contains unique Journal Volumes in all RecoverPoint Systems. (Admin CLI command "get_group_volumes" can be helpful in identifying the Journal volumes used across each system.)

  1. On impacted CGs, navigate to the target copy's Journal tab.
  2. Click "Edit Journals" button, select new Journal Volume to add to the CG and clear the problem Journal Volume.

Additional Information

Documented in "Dell EMC RecoverPoint Deploying with Midrange Storage Technical Notes" Page 7 under Limitations:
Unlike VNX, Unity does not have storage groups. Therefore, all volumes are visible to all RPA clusters, including volumes that have already been protected by other RPA clusters. Ensure that you protect only unprotected volumes. If you protect a volume that is already protected:
  • Replication does not start
  • The link state indicates Paused by system
  • An error indicates that the volumes are already protected
  • Data corruption may occur if the selected volume is a journal volume in a different RPA cluster
