Terminating Client Connections

If after querying the status of the Gateway and client connections, you determine that the Gateway or a client’s I/O operation is “hung” or there is a deadlock situation between clients that are connected to the Gateway, you can reboot the Gateway to terminate all client connections.

However, before rebooting the Gateway, you may want to alert users that any I/O operations they have in progress and their client connections to the Gateway will be terminated. The users will then need to re-open new sessions on the Gateway after the reboot has occurred.

To terminate all client connections to the Gateway, at the Telnet prompt (>), type: reboot. Once the reboot occurs, users who previously had open sessions on the Gateway will likely get an I_ERR_TIMEOUT or I_ERR_NOCONN error message. Since the reboot terminates all client connections, those users will need to re-open new sessions on the Gateway after the reboot occurs.

CAUTION

Any client operations in progress and client connections will be terminated by the reboot command when it reboots the Gateway.
