Configuring VSM Backup and Recovery

This chapter describes how to configure the backup and recovery procedures on the Virtual Supervisor Module (VSM).

This chapter includes the following sections:

Information About VSM Backup and Recovery

You can use the VSM backup and recovery procedure to create a template from which the VSMs can be re-created in the event that both VSMs fail in a high availability (HA) environment.


Note We recommend that you do periodic backups after the initial backup to ensure that you have the most current configuration. See the “Performing a Periodic Backup” section.


Guidelines and Limitations

VSM backup and recovery has the following configuration guidelines and limitations:

  • Backing up the VSM VM is a onetime task.
  • Backing up the VSM VM requires coordination between the network administrator and the server administrator.
  • The following procedures are applicable starting with Release 4.0(4)SV1(3) and later releases.
  • These procedures are not for upgrades and downgrades.
  • These procedures require that the restoration is done on the VSM with the same release as the one from which the backup was made.
  • Configuration files do not have enough information to re-create a VSM.

Configuring VSM Backup and Recovery

This section includes the following topics:


Note Be aware that Cisco NX-OS commands might differ from the Cisco IOS commands.


Backing Up the VSM

This section includes the following topics:

Performing a Backup of the VSM VM

This section describes how to create a backup of the VSM.

BEFORE YOU BEGIN

Before beginning this procedure, you must know or do the following:

  • If the VSM is on a Virtual Ethernet Module (VEM) host, you must configure the management VLAN as a system VLAN.
  • Enter the copy running-config startup-config command at the VSM before beginning this procedure.
  • This procedure is required when there is a Certificate change, Extension key change, after an upgrade to a new release, and installation of the license.

PROCEDURE

This section describes how to back up the active VSM after the initial backup of the standby VSM has been performed.

The following lists some instances when you should run this procedure:

  • You have performed an upgrade.
  • You have made a significant change to the configuration.

PROCEDURE


Step 1 Back up the VSM by entering a command similar to the following:

switch# copy running-config scp://root@10.78.19.15/tftpboot/config/
Enter destination filename: [switch-running-config]
Enter vrf (If no input, current vrf 'default' is considered):
The authenticity of host '10.78.19.15 (10.78.19.15)' can't be established.
RSA key fingerprint is 29:bc:4c:26:e3:6f:53:91:d4:b9:fe:d8:68:4a:b4:a3.
Are you sure you want to continue connecting (yes/no)? yes

Note This step is necessary if features are configured directly through the interface configuration mode for Ethernet interfaces and for features like ERSPAN/NFM.


Step 30 Copy the running-configuration to the startup-configuration by entering the following command:

switch# copy running-config startup-config
[########################################] 100%
switch#
 

Step 31 Create the standby VSM by using the OVA/OVF files to form an HA pair. See the “Installing the Software from an OVA or OVF Image” section in the Cisco Nexus 1000V Software Installation Guide, Release 4.2(1)SV1(4a) .

  • For release 4.2(1)SV1(4) and later releases, deploy the OVF template from the VMware vSphere Client and choose Nexus 1000V Secondary from the Configuration drop-down list.
  • For release 4.0(4)SV1(2) through release 4.0(4)SV1(3d), choose Manual Install of Nexus 1000V from the Configuration drop-down list and assign the HA role of secondary in the System Admin Setup of the VSM.

The recovery is complete.
