Why each option
Halting a Dell EMC Celerra NAS device requires logging into the Control Station as root and running the nas_halt command from the correct system path.
The nas_halt command resides at /nas/sbin/nas_halt and must be executed on the Control Station, which is the management node for the Celerra NAS system. Root privileges are required to execute this privileged shutdown command, making 'root' on the Control Station the correct login context.
The Celerra system uses 'root' as the privileged user for shutdown commands, not a user named 'master', making this login credential incorrect.
Celerra Manager is a GUI-based management interface and does not provide a shell environment to run system commands like nas_halt; the Control Station CLI is required.
Both the use of 'Celerra Manager' as the interface and 'master' as the username are incorrect; additionally, 'Celerra_halt' is not a valid command name.
