vradmin verify data operation fails when replication is in DCM mode (4112686)

This issue is observed when the VVR replication state is in the Data Change Map (DCM) mode. When you try to perform VVR data verification, the vradmin -verifydata command fails.

The following error is displayed on the primary:

VxVM VVR vxibc ERROR V-5-1-5420 Cannot send IBC while DCM is active
<!--NeedCopy-->

The verify data operation uses the VVR IBC functionality to compare and verify the integrity of the data volumes using point-in-time snapshots. The IBC functionality itself requires that the replication is active from the SRL.

However, the VVR replication remains inactive when VVR is in DCM mode or until the DCM synchronization between the primary and the secondary is completed. As the replication is not active, the verify data operation fails.

Workaround: Wait for the DCM resynchronization to complete and the replication to start from the SRL. You can verify the data once the replication is in active state.
