To run a command on any system in a cluster
# hacli -cmd command [-sys | -server system(s)]
Issues a command to be executed on the specified system(s). VCS must be running on the systems.
The use of the hacli command requires setting HacliUserLevel to at least COMMANDROOT. By default, the HacliUserLevel setting is NONE.
If the users do not want the root user on system A to enjoy root privileges on another system B, HacliUserLevel should remain set to NONE (the default) on system B.
You can specify multiple systems separated by a single space as arguments to the option -sys. If no system is specified, command runs on all systems in cluster with VCS in a RUNNING state. The command argument must be entered within double quotes if command includes any delimiters or options.
