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
permanent primary unit" on page 87
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.
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
cluster member.
4 Enter the following command to change the host name of the cluster member.
