Starting, Stopping and Statusing the acslsha Service

ACSLS HA uses a Linux 7.3, 7.6, or 7.8 service for control. This service is called acslsha.

Starting the acslsha Service

To start the service, issue the following command on both nodes:

#systemctl start acslsha

The node that you start first becomes the primary node. Start ACSLS and render the Logical Host IP to which ACSLS clients will attach.

The node that you start second becomes the secondary node. This node monitors the primary node and remains in standby until a failover occurs.

Stopping the acslsha Service

To stop acslsha, first ensure that there is no activity or outstanding operations in ACSLS. Then enter, the following command:

#systemnctl stop acslsha

Note:

If you stop the primary node, the product will fail over to the secondary. If you wish to shut down acslsha gracefully, stop the secondary node first.
It may take several minutes before acslsha completely stops, as it must first shut down ACSLS.

Statusing the acslsha Service

To check status, enter the following command:

#systemnctl status acslsha

Typical acslsha status from a node that is running:

# systemctl status acslsha
