::> system node run -node <node_name> - To exit nodeshell back to clustershell, type 'exit' or 'Ctrl-D'
- Nodeshell commands can be run directly from clustershell by using the following syntax:
::> node run -node <nodename> -command <nodeshell command> - To see a list of available nodeshell commands, type '?' at an interactive nodeshell prompt
- Nodeshell for any node in the cluster can be accessed from any other node
Systemshell
- Low level shell used for advanced, diagnostic and troubleshooting purposes
- Under normal circumstances systemshell should not be used without directions from NetApp Support
