2.
Replace [node_name] with your Data Node's name (for example, node0001).
3.
Copy the updated command and paste it into the CLI, then press Enter to review
the most recent entries in the ErrorReport.txt error file. If the error message
notes possible data consistency or data corruption issues, proceed to the next
step to force a Vertica restart.
4.
Copy the following command and paste it into a text editor:
admintools -t restart_node --hosts=[data-node-ip-address]
--database='sw-datastore' --password="[dbadmin-password]"
--force
5.
Replace [data-node-ip-address] with your affected Data Node's
IPaddress.
6.
Replace [dbadmin-password] with your Data Store dbadmin password.
7.
Copy the updated command and paste it into the CLI, then press Enter to force a
restart of Vertica on your affected Data Node. Vertica deletes any corrupted data,
and recovers that data from adjacent Data Nodes.
8.
If the system prompts you with Do you want to continue waiting?
(yes/no) [yes], enter yes and press Enter to continue waiting.
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.
What to Do Next
l
Review Cisco's recommendations for supplying power to your Data Nodes in Data
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 UCS C-Series GUI Configuration Guide for more
information on configuring the power restore policy in CIMC.
