Overview

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.

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

To use SSH for halting your appliance or doing a warm restart, complete these steps:

Before you begin

The prerequisites for this procedure include:

  • 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.

    You can identify the Enterprise port by looking at the rear-panel figures in Front and Rear Panels.

  • The Linux user name (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 needs to 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:

  • 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 appears 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

To halt your appliance or do a warm restart using the Cisco IMC GUI, complete these steps.

Before you begin

Note

  • You will need the Linux user name (maglev ) and the password that is currently configured on the target appliance.

  • Any hardware changes you make using the Cisco IMC GUI apply after the appliance reboots.

Caution

To prevent data loss, only power-cycle your appliance from the Cisco IMC GUI when it is 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, and log in to the Cisco IMC GUI as the Cisco IMC user. (see Enable browser access to the Cisco Integrated Management Controller).

After you log in, the appliance shows the Cisco Integrated Management Controller Chassis Summary window with a hyperlinked menu at the top of the window.
2.

Reboot the appliance by choosing Host Power > Power Cycle.

If prompted to confirm rebooting the appliance, click OK.
3.

When prompted, enter the Linux password.
