Why do some CSM commands require the use of the -n flag when specifying nodes, and some commands do not require the -n flag?
The -n flag is used by all CSM commands to specify the nodes to act upon. As a convenience, for commands whose primary input is node names, CSM supports node names as positional arguments, and the -n flag is not required. Some of the commands that do not require the -n flag to specify nodes are lsnode, chnode, updatenode and installnode. See each command’s man page or usage message to determine each command’s syntax.
