Viewing Database Cluster State

This tool shows the current state of the nodes in the database.

  1. On the Main Menu, select View Database Cluster State, and click OK.
    The normal state of a running database is ALL UP. The normal state of a stopped database is ALL DOWN.

    NormalStateIsALLUP

  2. If some hosts are UP and some DOWN, restart the specific host that is down using Restart Vertica on Host from the Administration Tools, or you can start the database as described in Starting and Stopping the Database (unless you have a known node failure and want to continue in that state.)

    SomeUP_SomeDOWN

    Nodes shown as INITIALIZING or RECOVERING indicate that Failure Recovery is in progress.

Nodes in other states (such as NEEDS_CATCHUP) are transitional and can be ignored unless they persist.
