restart of Vertica on your affected Data Node. Vertica deletes any corrupted data,
and recovers that data from adjacent Data Nodes.

If the system prompts you with
(yes/no) [yes]
Because Vertica restores the affected Data Node's information from adjacent Data
Nodes, if these Data Nodes ingested a large amount of flow traffic while the
affected Data Node was down, it may take a period of time for the affected Data
Node to recover.

Store Deployment Requirements and Considerations
Data Store Does Not Start After Power Failure:
If multiple Data Nodes lose power unexpectedly, and the Data Store database goes
down, it may not automatically restart after you restore power to the affected Data
Nodes.
In this case, make sure that you enable SSH on all Data Nodes in Central Management.
Then, log into a Data Node and force a restart of the Data Store database.
In addition, you may need to update the Data Node's power restore policy before it
restarts. If the power restore policy is set to Power Off, you must manually restart the
Data Node after power loss. See the
information on configuring the power restore policy in CIMC.
