User Privileges for CLI Commands

The following concepts apply to users executing commands from the command line:

• Users logged on as root (or administrator) are granted privileges that exceed those of Cluster Administrator, such as the ability to start and stop a cluster.
• When non-root users execute haxxx commands, they are prompted for their VCS user name and password to authenticate themselves. Use the halogin command to save the authentication information so that you do not have to enter your credentials every time you run a VCS command. You must also set the VCS_HOST environment variable to the name of the node on which to run commands. You can also set the variable to the virtual IP address configured in the ClusterService group. Users must have proper cluster- and group-level privileges to execute commands. You cannot remotely run ha commands that require localhost root privileges. See Logging On to VCS for more information about the halogin command.
