## To perform maintenance on a single machine

This procedure is applicable to both planned and unplanned maintenance, and does not interrupt HADB availability.

1. Perform the maintenance procedure and get the machine up and running.

2. Ensure that `ma` is running.

   If `ma` runs as a Windows service or under `init.d` scripts (recommended for deployment), it should have been started by the operating system. If not start it manually. See Starting the Management Agent.

3. Start all nodes on the machine.

   For more information, see Starting a Node.

4. Check whether the nodes are active and running.

   For more information, see Getting the Status of HADB
