Consistency check in progress

Published : April 8, 2005 | Updated : August 17, 2005

Summary

This alert is generated when a consistency check is in progress for the specified replica. A consistency check is the process by which Data Protection Manager (DPM) checks for and corrects inconsistencies between a protected volume and its replica. After initial replication, DPM initiates a consistency check only when normal mechanisms for recording changes to protected volumes and for applying those changes to replicas have been interrupted.

Causes

A consistency check is required when any of the following events occur:

  • A new replica is created as part of the process of creating a protection group

  • Members are added to an existing protection group

  • The synchronization log has run out of disk space

  • The file server was unexpectedly shut down.

DPM automatically initiates a consistency check when a replica is created or when members are added to an existing protection group. To ensure that a replica stays consistent with its data source, you can schedule a daily consistency check. If you do not schedule a daily consistency check, you must manually perform a consistency check when a replica becomes inconsistent. DPM generates a “replica is inconsistent” alert so you will know when a manual consistency check is required.

Resolutions

This alert is for your information only, and no action is required.
