Last Updated:

Applies to

  • Active IQ Unified Manager


  • Erroneous alerts are generated against backup relationships managed by CommVault which apparently fail to replicate
  • These replications ultimately occur, and nothing obvious is seen on the CommVault side
  • Closer inspection may reveal a "Error processing chunk" followed by success on a retry from CommVault's side
  • Alerts from Active IQ Unified Manager appear as the following:

Trigger Condition - Protection Job Failed. Reason: (Relationship 'cluster1:Prod->cluster2:CC_prodCV_SP_420_Copy_1120_cluster1_Prod_Backup' is missing source volume and update cannot be supported.).
