To manage a cluster unit
1Use SSH to connect to the cluster and log into the CLI.
Connect to any cluster interface configured for SSH management to log into the cluster.
You can also use a direct cable connection to log into the primary unit CLI. (To do this you must know which unit is the primary unit. See “Selecting a FortiGate unit as a permanent primary unit” on page 87 to control which FortiGate unit becomes the primary unit).
2Enter the following command followed by a space and type a question mark (?): execute ha manage
The CLI displays a list of all the subordinate units in the cluster. Each cluster unit is numbered, starting at 1. The information displayed for each cluster unit includes the unit serial number and host name of the unit.
3Complete the command with the number of the subordinate unit to log into. For example, to log into subordinate unit 1, enter the following command: execute ha manage 1
Press Enter and you are connected to and logged into the CLI of the selected subordinate unit. If this subordinate unit has a different host name, the CLI prompt changes to this host name. You can use CLI commands to manage this subordinate unit.
4Enter the following command to return to the primary unit CLI: exit
You can use the execute ha manage command to log into the CLI of any of the other subordinate units in the cluster.
Changing cluster unit host names
You can identify individual cluster units by giving each unit a unique host name. The host name is the only configuration setting not synchronized by the cluster.
To set the host name of each cluster member
1Use SSH to connect to the cluster and log into the CLI.
2Enter the following command to change the host name of the primary unit: set system hostname <hostname_str>
3Use the information in “Managing individual cluster units” on page 83 to log into each cluster member.
4Enter the following command to change the host name of the cluster member. set system hostname <hostname_str>
5Repeat steps 3 and 4 for each cluster member.
