RLM CLI and system console sessions

Only one administrator can log in to an active RLM CLI session at a time. However, the RLM allows you to open both an RLM CLI session and a separate, RLM-redirected system console session simultaneously.

The RLM prompt appears with RLM in front of the host name of the storage system. For example, if your storage system is named toaster, the storage system prompt is toaster> and the prompt for the RLM session is RLM toaster>.

If an RLM CLI session is currently open, you or another administrator with privileges to log in to the RLM can close the RLM CLI session and open a new one. This feature is convenient if you logged in to the RLM from one computer and forgot to close the session before moving to another computer, or if another administrator takes over the administration tasks from a different computer.

When you use the RLM's system console command to connect to the storage system console from the RLM, you can start a separate SSH session for the RLM CLI, leaving the system console session active. When you press Ctrl-d to exit from the storage system console, you automatically return to the RLM CLI session. If an RLM CLI session already exists, the following message appears:

User username has an active CLI session.
Would you like to disconnect that session, and start yours [y/n]?

If you enter y, the session owned by username is disconnected and your session is initiated. This action is recorded in the RLM’s system event log.

If you use the RLM to power-cycle the storage system, no real-time messages regarding the boot progress appear in the RLM console. To monitor the storage system during a power cycle, you can keep the RLM CLI session and the system console session active simultaneously. The system console session provides real-time output from the system, including the progress of the system boot.
