Are you sure that's such a good idea?

You want to change the root password on a handful of servers. Is that so complicated?

Reading your original post again, I may have mis-interpreted this at the time:

Quote:
NB. from server1 i can via ssh connect to the others machines without a password
The root password has absolutely nothing to do with connecting to other machines via ssh.

restart-instance

asadmin-restart-instance(1AS)					   User Commands				     asadmin-restart-instance(1AS)

NAME

       asadmin-restart-instance, restart-instance - restarts the specified server instance and all the services associated with it

SYNOPSIS

       restart-instance  [--user  admin_user]  [--password admin_password] [--host localhost] [--port 4848] [--local=false] [--domain domain_name]
       [--passwordfile filename] [--secure|-s]instance_name

       Use the restart-instance to restart the instance with the instance name specified. The restart-instance command can be run both locally and
       remotely.  To restart remotely, the administration server must be running on the hostname and port number specified. The user authenticates
       using the password identified for the administration server. Additionally, the instance must already exist within the domain served by  the
       administration server, and the instance must be running.  The restart-instance command is not supported on Windows.

OPTIONS

       --user		       administrative user associated for the instance.

       --password	       administrative password corresponding to the administrative user.

       --host		       host name of the machine hosting the administrative instance.

       --port		       administrative port number associated with the administrative host.

       --local		       determines if the command should delegate the request to administrative instance or run locally.

       --domain 	       name of the domain.

       --passwordfile	       file containing passwords appropriate for the command (e.g., administrative instance).

       --secure 	       if true, uses SSL/TLS to communicate with the administrative instance.

OPERANDS

       instance_name	       name of the instance to be restarted.

       Example 1: Using restart-instance in local mode

       asadmin> restart-instance --local --domain domain1 server1
       Instance server1 started

       Where: server1 is the name of the instance restarted on the domain1 domain.

       Example 2: Using restart-instance in remote mode

       asadmin> restart-instance --user admin --password adminadmin --host bluestar --port 4848 server1
       Instance server1 started

       Where:  server1	is the name of the instance restarted. The restarted instance is associated with the user, password, host, and port number
       specified.

EXIT STATUS

       0		       command executed successfully

       1		       error in executing the command
