Starting and stopping cluster nodes manually

You may need to stop the entire Kaspersky Security Center failover cluster or temporarily detach one of the nodes of the cluster for maintenance. If this is the case, follow the instructions in this section. Do not try to start or stop the services or processes related to the failover cluster by using any other means. This may cause data loss.

Starting and stopping the entire failover cluster for maintenance

To start or stop the entire failover cluster:

On the active node, go to <Disk>:\Program Files (x86)\Kaspersky Lab\Kaspersky Security Center.
Open the command line, and then run one of the following commands:
- To stop the cluster, run: klfoc -stopcluster --stp klfoc
- To start the cluster, run: klfoc -startcluster --stp klfoc

The failover cluster is started or stopped, depending on the command that you run.

Maintaining one of the nodes

To maintain one of the nodes:

On the active node, stop the failover cluster by using the klfoc -stopcluster --stp klfoc command.
On the node that you want to maintain, go to <Disk>:\Program Files (x86)\Kaspersky Lab\Kaspersky Security Center.
Open command line, and then detach the node from the cluster by running the detach_node.cmd command.
On the active node, start the failover cluster by using the klfoc -startcluster --stp klfoc command.
Perform maintenance activities.
On the active node, stop the failover cluster by using the klfoc -stopcluster --stp klfoc command.
On the node that was maintained, go to <Disk>:\Program Files (x86)\Kaspersky Lab\Kaspersky Security Center.
Open command line, and then attach the node to the cluster by running the attach_node.cmd command.
On the active node, start the failover cluster by using the klfoc -startcluster --stp klfoc command.

The node is maintained and attached to the failover cluster.
