Configuring VSM Backup and Recovery

This chapter contains 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 for more information.


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.

  • 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:

  • Performing a Backup of the VSM VM

  • Performing a Periodic Backup

  • Recovering the VSM


Note


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

    Exporting a Backup VSB Configuration on Cisco Nexus Cloud Services Platform Server

    You can export or import a VSB on the Cisco Nexus Cloud Services Platforms by creating a copy of the VSB backup file. You can store the backup copy remotely to use as a recovery mechanism or when you need to move a VSB between Cisco Nexus Cloud Services Platforms. Use the procedures in the following sections to export and import a VSB on the Cisco Nexus Cloud Services Platform.

    Exporting a VSB

    You can create a file for exporting a VSB.


    Note


    You can create multiple files. Do not change the file suffix for numbering purposes. If you change the prefix for one file, you must change it for all files.


    Before You BeginBefore beginning this procedure, you must know or do the following:
    • Ensure that you are on Cisco Nexus Cloud Services Platform. If you want to perform this procedure on ESX platform refer to Performing a Backup of the VSM VM.

    • Log in to the CLI of theCisco Nexus Cloud Services Platform in EXEC mode.

    • Know the name of the VSB for which you are creating a file to export.

    • Verify that the bootflash: export-import directory is empty. If files are present in this directory, you must delete them before starting this procedure.

    • Enter the copy running-config startup-config command at the VSB before beginning this procedure.

    • Shut down the VSB that you want to back up before creating the file to export. This procedure includes a step for shutting down the VSB and then a step to restart the VSB after creating the file.

    Procedure
       Command or ActionPurpose
      Step 1 switch # dir bootflash:export-import  

      Displays the contents of the export-import directory for verification that the directory is empty. If there is anything in this directory, you must use the next step to delete it before proceeding.

       
      Step 2switch (config-vsb-config) # delete bootflash:export-import foldername  

      (Optional) Deletes the VSB compressed tar file and its folder created for export.

       
      Step 3switch # configure terminal  

      Enters global configuration mode.

       
      Step 4switch (config) # virtual-service-blade name  

      Enters the configuration mode for the named virtual service blade.

       
      Step 5switch (config-vsb-config) # shutdown [primary | secondary]  

      Shuts down the VSB that you are exporting from. If you have a redundant pair of Cisco Nexus Cloud Services Platforms, you must specify whether to shut down the primary or secondary.

       
      Step 6switch (config-vsb-config)# show virtual-service-blade summary  

      (Optional) Displays the virtual service blade configuration for verification.

       
      Step 7switch (config-vsb-config) # export [primary | secondary]  

      Creates a directory named for the slot ID of the exported VSB that contains a compressed tar image of the VSB.

      If exporting from a redundant pair of Cisco Nexus Cloud Services Platforms, you must specify whether you are exporting from the primary or secondary.
      Note   

      The export command does not move the configuration file off of the Cisco Nexus Cloud Services Platform. The export command creates a backup copy that you must then copy to the remote storage location.

       

      Step 8switch (config-vsb-config) # dir bootflash:export-import  

      Displays the contents of the bootflash: export-import directory, including the directory name of the folder that contains the compressed tar image of the VSB, for verification.

      You need this folder name in Step 11.

       
      Step 9switch (config-vsb-config) # no shutdown [primary | secondary]  

      Powers on the VSB that was powered off when creating the file for export. If you have a redundant pair of Cisco Nexus Cloud Services Platforms, you must specify primary or secondary.

       
      Step 10switch (config-vsb-config)# show virtual-service-blade summary  

      Displays the virtual service blade configuration for verification.

       
      Step 11switch (config-vsb-config) # dir bootflash:export-import /directory-name  
      Displays the contents of the Cisco Nexus Cloud Services Platform export folder, including the filename of the VSB compressed tar image.
      Note   
      1. You identified this folder name in Step 8.

      2. You can create multiple files. Do not change the file suffix for numbering purposes. If you change the prefix for one file, then you must change it for all files.

              Example:
              Enable the ssh service? (yes/no) [y]: yes
              Type of ssh key you would like to generate (dsa/rsa) : rsa
              Number of key bits <768-2048> : 1024
              Step 14   Enter yes when asked to enable the HTTP server.

              Example:
              Enable the http-server? (yes/no) yes
              Step 15   Enter no when asked to configure the NTP server

              Example:
              Configure NTP server? (yes/no) [n]: no
              Step 16   Enter no when asked to configure the VEM feature level.

              Example:
              Vem feature level will be set to 4.2(1)SV1(4a). 
              Do you want to reconfigure? (yes/no) [n] no

              The system now summarizes the complete configuration and prompts you to edit it.



              Example:
              The following configuration will be applied:
               interface Mgmt0
              ip address 172.28.15.152 255.255.255.0
              no shutdown
              vrf context management
              ip route 0.0.0.0/0 10.78.111.11
                no telnet server enable
                ssh key rsa 1024 force
                ssh server enable
                feature http-server
                svs-domain
                  svs mode L2
                  control vlan 1
                  packet vlan 1
                  domain id 1
              Step 17   Enter no when asked if you would like to edit the configuration.

              Example:
              Would you like to edit the configuration? (yes/no) [n]: no
              
              Enter SVS Control mode (L2 / L3) : L2
              Enter control vlan <1-3967, 4048-4093> : 100
              Enter packet vlan <1-3967, 4048-4093> : 101
              Step 18   Enter yes when asked to use and save this configuration.

              Example:
              Use this configuration and save it? (yes/no) [y]: yes
              [########################################] 100%
              

              If you do not save the configuration now, then none of your changes are part of the configuration the next time the switch is rebooted. Enter yes to save the new configuration. This ensures that the kickstart and system images are also automatically configured.

              Step 19   In the vSphere Client, right-click the VSM and choose Edit Settings.

              The VSM Virtual Machine Properties window opens.

              Step 30   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 Installation and Upgrade Guide.
              • 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.

              Recovering a VSM with a Backup Configuration File on Cisco Nexus Cloud Services Platform Server


              Note


              This procedure is only for Cisco Nexus Cloud Services Platform. If you want to perform this procedure on ESX platform refer to Deploying the Backup VSM VM.
              You can import a previously saved location backup copy of a VSB from a remote storage location to the Cisco Nexus Cloud Services Platform to recover a VSM. This section includes:
              Importing a VSB

              Before You Begin

              • Log in to the CLI of the activeCisco Nexus Cloud Services Platformin EXEC mode.

              • You have previously created and saved a copy of the VSB configuration in a remote storage location using the Exporting a Backup VSB Configuration.


                Note


                You can create multiple. If so, use only the first filename with the import command. Do not change the file suffix for numbering purposes. If you change the prefix for one file, then you must change it for all files.


              • Know the name of the VSB and the path to the remote storage location.

              • Verify that the bootflash: export-import directory is empty. If files are present in this directory, you must delete them before importing a VSB configuration file.

              Procedure
                 Command or ActionPurpose
                Step 1 switch # dir bootflash:export-import  

                Displays the contents of the export-import directory for verification that the directory is empty. If there is anything in this directory, you must use the next step to delete it before proceeding.

                 
                Step 2switch (config-vsb-config) # (optional)delete bootflash:export-import foldername  

                (Optional) Deletes the VSB compressed tar file and its folder created for export.

                 
                Step 3switch # copy ftp:filenamebootflash:export-import  

                Copies the exported image file from a remote storage location into the Cisco Nexus Cloud Services Platform export-import folder in the bootflash: repository.

                • The filename argument is the name of the export file. Multiple files may have been created. If so, copy these files into export-import directory and use only the first filename with the import command. Do not change the file suffix for numbering purposes. If you change the prefix for one file, then you must change it for all.

                 
                Step 4 switch # configure terminal  

                Enters the global configuration mode.

                 
                Step 5switch (config) # virtual-service-blade name  

                Enters the configuration mode for the named virtual service blade.

                 
                Step 6switch (config-vsb-config) # import primary filename  

                Powers off the primary VSB, imports the specified VSB configuration file, and then removes the configuration file from the export-import folder.

                • The filename argument is the name of the export file that you copied from the remote server to the bootflash: repository.

                 
                Step 7switch (config-vsb-config)# show virtual-service-blade summary  

                (Optional) Displays a summary of all VSB configurations by type name, such as VSM or NAM. Verify that the primary VSB is powered off.

                 
                Step 8Configure the network uplinks by completing the following set of tasks. These tasks might vary based on the network toplogy and uplink types:
                • Modifying the uplink type
                • Migrating from static to flexible uplink
                • Migrating from flexible to static uplink
                • Configuring port channels
                • Assigning uplinks to a VSB Interface
                 

                Configures your network uplinks with the procedures listed in Configuring Network Uplink Types section.

                 
                Step 9switch # no shutdown primary filename  

                Powers on the primary VSB and imports the primary VSB configuration. The filename argument is the name of the imported primary VSB

                 
                Step 10switch (config-vsb-config) # show virtual-service-blade name name  

                Displays the virtual service blade information for verification. From the command output, make a note of the control and management VSB Ethernet interfaces.

                 
                Step 11switch (config-vsb-config) # copy running-config startup-config  

                Saves the running configuration persistently through reboots and restarts by copying it to the startup configuration.

                 

                The following example shows how to import a VSB backup file:

                Recovering a VSM with a Backup Configuration File

                You can recover a VSM using a backup configuration file.

                Before You Begin

                • You have imported your backup copy of the configuration file using the instructions in Importing a VSB.

                • You have a copy of the VSM running configuration in remote storage location.

                • Log in to the CLI of the Cisco Nexus Cloud Services Platform in EXEC mode.

                • This procedure includes a step for updating Cisco Nexus 1000V licenses. For more information, see the Cisco Nexus 1000V License Configuration Guide.

                • This procedure requires you to shut down the VSM management and control ports to prevent communication with VEMs and vCenter during the recovery. You must know the IDs of the VSM control and management ports and the VSB serial port.

                • This procedure requires you to setup the VSM software. You must have the following information available for the VSM VSB:

                  • Admin password

                  • Domain ID

                  • HA role (must be set to the same role as that of the VSM on which it is imported)

                  • Management 0 IP address

                  • Management 0 netmask

                  • Default gateway IP address

                Procedure
                  Step 1   From the Cisco Nexus Cloud Services Platform, shut down the control and management interfaces of the VSM VSB.

                  The VSM management and control interfaces are no longer communicating with VEMs and vCenter.

                  Step 2   Verify that the control and management interfaces are down.
                  Step 3   Power on the VSB VSM.
                  Step 4   Log in to the Cisco Nexus Cloud Services Platform serial port of the primary VSM.
                  Step 5   Erase the startup configuration.

                  The previous configuration is erased. You will replace it with the previously-saved backup of your running configuration in Step 11.

                  Step 6   Reboot the system.

                  The Cisco Nexus Cloud Services Platform boots up and the setup wizard starts.

                  Step 7   Use the setup wizard to configure the VSM. Accept defaults for all except the following:
                  • Admin password

                  • Domain ID

                  • HA Role (must be set to the same role as that of the VSM on which it is imported)

                  • Management 0 IP address

                  • Management 0 netmask

                  • Default gateway IP address

                  The system summarizes the new setup configuration.

                  Step 8   Copy the running configuration to the startup configuration using the copy running-config startup-configcommand.
                  Step 9   Reopen the management interface of the VSM VSB.

                  The VSM management interface is again communicating with VEMs and vCenter.

                  Step 10   Verify that the management interface is up.
                  Step 11   Copy your saved running configuration backup to the VSM bootflash using the copy bootflash: filenamecommand.
                  Step 12   Copy the running configuration to the startup configuration.
                  Step 13   Reopen the control interface of the VSM VSB.

                  The VSM control interface is again communicating with VEMs and vCenter.

                  Step 14   Verify that the control interface is up.
                  Step 15   Check the modules at the VSM CLI.
                  Step 16   Enable the HA peer.

                  The VSM is again operating in HA mode with a primary and secondary module.

                  This setup utility will guide you through the basic configuration of
                  the system. Setup configures only enough connectivity for management
                  of the system.
                  *Note: setup is mainly used for configuring the system initially,
                  when no configuration is present. So setup always assumes system
                  defaults and not the current system configuration values.
