The Nortel SNAS 4050 stops responding

Telnet or SSH connection to the MIP

When you are connected to a cluster of Nortel SNAS 4050 devices through a Telnet or SSH connection to the MIP, your connection to the cluster can be maintained as long as at least one Nortel SNAS 4050 device in the cluster is up and running. However, if the particular Nortel SNAS 4050 that currently is in control of the MIP stops responding while you are connected, you must close down your Telnet or SSH connection and reconnect to the MIP.

After you reconnect, use the /info/contlis command to view the operational status of all Nortel SNAS 4050 devices in the cluster. If the operational status of one of the Nortel SNAS 4050 devices is indicated as down, reboot that machine: On the Nortel SNAS 4050 device, press the Power button on the back panel to turn the machine off, wait until the fan comes to a standstill, and then press the Power button again to turn the machine on.

Log on as the Administrator user when the logon prompt appears and check the operational status again.

Console connection

If you are connected to a particular Nortel SNAS 4050 device through a console connection and the device stops responding, press the key combination Ctrl+^, then press Enter. This takes you back to the login prompt. Log on as the Administrator user and check the operational status of the Nortel SNAS 4050. Enter the command /info/contlist to view the operational status of the device.

If the operational status of the Nortel SNAS 4050 is indicated as down, try rebooting the device by typing the command /boot/reboot. You will be asked to confirm your action before the actual reboot is performed. Log on as the Administrator user and again use the /info/contlist command to check if the operational status of the Nortel SNAS 4050 is now up.
