Existingentries for the specified hosts are replaced within the local known_hosts file.When run in this mode the -S and -s options are ignored. This mode assumesssh has previously been setup for the hosts, as such no files are transferred tothe specified hosts and no passwords should be required.Typically after completing the installation and booting of IB software, setup_sshwill need to be rerun with the -C option to update the knownhosts file5.2.4cmdall(Linux and Switch): Executes a command on all hosts or SilverStorm IB chassis.This is very powerful and can be used for everything from configuring servers orchassis, verifying that they are running, starting and stopping host processes, etc.Usage:cmdall [-Cpq] [-f hostfile] [-F chassisfile] [-h 'hosts'] [-H'chassis'] [-u user] [-S] 'cmd'-C - perform command against chassis, default is hosts-p - run command in parallel on all hosts-q - quiet mode, do not show command to execute-f hostfile - file with hosts in cluster, default is/etc/sysconfig/iba/hosts-F chassisfile - file with chassis in cluster default is/etc/sysconfig/iba/chassis-h hosts - list of hosts on which to execute the command-H chassis - list of chassis on which to execute the command-u user - the user to perform the command as.
