Procedures to stop or start a warm reset on Catalyst Center appliance.

Complete one of these procedures on your Catalyst Center appliance to either stop it or start a warm restart. You can stop the appliance before you make hardware repairs, or you can initiate a warm restart after you have corrected software issues.

Note

Complete the SSH procedure to perform a graceful shutdown of your appliance. Only complete the Cisco IMC procedure if Catalyst Center is unresponsive and cannot be rebooted via SSH.

Using SSH

If you want to use SSH in order to halt your appliance or perform a warm restart, complete the following tasks:

Before you begin

You need the following:

  • Secure Shell (SSH) client software.

  • The IP address that you configured for the 10-Gbps Enterprise port on the appliance that needs reconfiguration. Log in to the appliance at this address, on port 2222.

    To identify the Enterprise port, see the rear-panel figures in Front and rear panels.

  • The Linux username (maglev ) and the password that is currently configured on the target appliance.

Procedure

1.

Using a Secure Shell (SSH) client, log in to the IP address of the Enterprise port of the appliance that must be reconfigured, on port 2222:

ssh maglev@Enterprise-port's-IP-address -p 2222

2.

When prompted, enter the Linux password.
3.

Enter the command that is appropriate for the task you want to perform:

  • To halt the appliance, enter: sudo shutdown -h now

  • To initiate a warm restart, enter: sudo shutdown -r now

    If you are prompted for the Linux password, enter it again.
4.

Review the command output that is displayed as the host shuts down.
5.

If you halted your appliance, power up the Maglev root process by turning the appliance back on, using the front-panel power button.

Using the Cisco IMC GUI

If you want to use the KVM console that is accessible from the Cisco IMC GUI in order to halt your appliance or perform a warm restart, complete the tasks described in this procedure.

Before you begin

Note that any hardware changes you make using the Cisco IMC GUI will be applied after the appliance reboots.

Caution

Power cycling your appliance from the Cisco IMC GUI can result in the corruption or loss of data. Only do so if your appliance is completely unresponsive to SSH, the Cisco IMC console, or the physical console.

Procedure

1.

Point your browser to the Cisco IMC IP address you set during the Cisco IMC GUI configuration you performed, and log in to the Cisco IMC GUI as the Cisco IMC user (see Enable browser access to the Cisco Integrated Management Controller).

After successful login, the appliance displays the Cisco Integrated Management Controller Chassis Summary window, with a hyperlinked menu at the top of the window, as shown below.

2.

With the KVM displayed, reboot the appliance by choosing Host Power > Power Cycle.

If you are asked to confirm your choice to reboot the appliance, click OK.
