The cluster has three different shells for CLI commands, the clustershell, the nodeshell, and the systemshell. Depending on the task you perform, you might need to use different shells to execute different commands.
It provides all the commands you need to configure and manage the cluster. The clustershell CLI help (triggered by ? at the clustershell prompt) displays available clustershell commands. The man command_name command in the clustershell displays the man page for the specified clustershell command.
The nodeshell is accessible through the system node run command.
The nodeshell CLI help (triggered by ? or help at the nodeshell prompt) displays available nodeshell commands. The man command_name command in the nodeshell displays the man page for the specified nodeshell command.
The systemshell is not intended for general administrative purposes. You access the systemshell only with guidance from technical support.
