Managing an HA cluster High availability

To manage a cluster unit

1 Use 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).

2 Enter 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.

3 Complete 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.

4 Enter 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

1 Use SSH to connect to the cluster and log into the CLI.

2 Enter the following command to change the host name of the primary unit:

set system hostname <hostname_str>

3 Use the information in “Managing individual cluster units” on page 83 to log into each

cluster member.

4 Enter the following command to change the host name of the cluster member.

set system hostname <hostname_str>

5 Repeat steps 3 and 4 for each cluster member.
