Managing individual cluster units
The following procedure describes how to use SSH to log into the primary unit CLI and from there to use the
execute ha manage command to connect to the CLI of any other unit in the cluster. The procedure is very similar if you use telnet, or the GUI dashboard CLI console.
You can use the
execute ha manage command from the CLI of any cluster unit to log into the CLI of another the cluster unit. Usually you would use this command from the CLI of the primary unit to log into the CLI of a subordinate unit. However, if you have logged into a subordinate unit CLI, you can use this command to log into the primary unit CLI, or the CLI of another subordinate unit.
Using SSH or telnet or the GUI dashboard CLI console you can only log into the primary unit CLI. Using a direct console connection you can log into any cluster unit. In both cases you can use
execute ha manage to connect to the CLI of other cluster units.
- Use SSH to connect to the cluster and log into the primary unit CLI.
Connect to any cluster interface configured for SSH administrative access to log into the cluster.
- 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 the host name of the unit.
- 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 to connect to and use an administrator account to log 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. If you make changes to the configuration of any cluster unit (primary or subordinate unit) these changes are synchronized to all cluster units.
- You can now use the
execute ha managecommand to connect to any other cluster unit (including the primary unit). You can also use the
exitcommand to return to the primary unit CLI.
