This chapter describes the Cisco NX-OS high availability (HA) system and application restart operations.
This chapter includes the following sections:
•Information About VSM Restarts and Switchovers
•Configuring System-Level High Availability
This section includes the following topics:
•Information About Single and Dual Supervisors
•Information About VSM Restarts and Switchovers
The Cisco Nexus 1000V can be configured with a single virtual supervisor module (VSM) or dual VSMs. Table 3-1 describes the HA supervisor roles for single and dual VSM operation.
The redundancy role indicates not only whether the VSM interacts with other VSMs, but also the module number it occupies. Table 3-2 shows the available HA roles for VSMs.
Independent of its role, the redundancy state of a VSM can be one of those described in Table 3-3.
The active and standby VSMs are in the operationally HA state and can automatically synchronize when the internal state of one supervisor module is Active with HA Standby and the internal state of the other supervisor module is HA Standby.
If the output of the show system redundancy command indicates that the operational redundancy mode of the active VSM is None, then the active and standby VSMs are not yet synchronized. The following example shows the VSM internal state of dual supervisors as observed in the output of the show system redundancy status command.
switch# show system redundancy status

switch#
This section includes the following topics:
In a system with only one supervisor, when all HA policies have been unsuccessful in restarting a service, the supervisor restarts. The supervisor and all services restart with no prior state information.
When a VSM fails in a system with dual supervisors, the system performs a switchover rather than a system restart in order to maintain a stateful operation. In some cases, however, a switchover may not be possible at the time of the failure. For example, if the standby VSM is not in a stable standby state, a restart rather than a switchover is performed.
A dual VSM configuration allows uninterrupted traffic forwarding with stateful switchover (SSO) when a failure occurs in the VSM. The two VSMs operate in an active/standby capacity in which only one is active at any given time, while the other acts as a standby backup. The two VSMs constantly synchronize the state and configuration in order to provide a seamless and stateful switchover of most services if the active VSM fails.
This section includes the following topics:
A switchover occurs when the active supervisor fails (for example, if repeated failures occur in an essential service or if the system hosting the VSM fails).
A user-triggered switchover could occur (for example, if you need to perform maintenance tasks on the system hosting the active VSM).
An HA switchover has the following characteristics:
•It is stateful (nondisruptive) because control traffic is not affected.
•It does not disrupt data traffic because the VEMs are not affected.
When a stable standby VSM detects that the active VSM has failed, it initiates a switchover and transitions to active. When a switchover begins, another switchover cannot be started until a stable standby VSM is available.
If a standby VSM that is not stable detects that the active VSM has failed, then, instead of initiating a switchover, it tries to restart the system.
Before you can initiate a manual switchover from the active to the standby VSM, the standby VSM must be stable. To find out if it is, see the "Verifying that a System is Ready for a Switchover" section.
Once you have verified that the standby VSM is stable, you can manually initiate a switchover (see the "Manually Switching the Active VSM to Standby" section).
Once a switchover process begins, another switchover process cannot be started until a stable standby VSM is available.
Follow these guidelines and limitations when configuring system-level high availability:
•Although primary and secondary VSMs can reside in the same host, to improve redundancy, install them in separate hosts and, if possible, connected to different upstream switches.
•The console for the standby VSM is available through the vSphere client or using the command, module attach <x>, but configuration is not allowed and many commands are restricted. The module attach <x> command would be run at the console of the active VSM.
•You cannot use Telnet or Secure Shell (SSH) protocols to communicate with the standby VSM because the management interface IP is unconfigured until the VSM becomes active.
This section includes the following topics:
•Adding a Second VSM to a Standalone System
•Replacing the Standby in a Dual VSM System
•Replacing the Active in a Dual VSM System
•Changing the Domain ID in a Dual VSM System
Use this procedure to change the role of a VSM to one of the following after it is already in service:
•Standalone
•Primary
•Secondary
Before beginning this procedure, you must know or do the following:
•If you are changing a standalone VSM to a secondary VSM, be sure to first isolate it from the other VSM in the pair to prevent any interaction with the primary VSM during the change. Power the VM off from the vSphere Client before reconnecting it as standby.
For an example of changing the port groups and port profiles assigned to the VSM interfaces in the vSphere Client, see the following document:
–Cisco Nexus 1000V Getting Started Guide, Release 4.0(4)SV1(3)
To change a standalone VSM to a secondary VSM, see the "Adding a Second VSM to a Standalone System" section.
•You are logged into the CLI in EXEC mode.
Note The Cisco Nexus 1000V VSM software installation provides an opportunity for you to designate the role for each VSM. You can use this procedure to change that initial configuration.
•The possible HA roles are standalone, primary, and secondary.
For more information, see the "HA Supervisor Roles" section.
•The possible HA redundancy states are active and standby.
For more information, see the "Dual Supervisor Active and Standby Redundancy States" section.
•To activate a change from primary to secondary VSM, you must reload the VSM by doing one of the following:
–Issue the reload command.
–Power the VM off and then on from the vSphere Client.
•A change from a standalone to a primary VSM takes effect immediately.
1. system redundancy role {standalone | primary | secondary}
2. show system redundancy status
3. copy running-config startup-config
This example shows how to display the system redundancy status of a standalone VSM:
switch# show system redundancy status
Redundancy role

administrative: HA
operational: None
This supervisor (sup-1)
-----------------------
Redundancy state: Active
Supervisor state: Active
Internal state:Active with no standby
Other supervisor (sup-2)
------------------------
Redundancy state: Not present
switch#
This section includes the following procedures for configuring a switchover in a dual VSM system:
•Verifying that a System is Ready for a Switchover
•Manually Switching the Active VSM to Standby
Follow these guidelines when performing a switchover:
•When you manually initiate a switchover, system messages are generated that indicate the presence of two VSMs and identify which one is becoming active.
•A switchover can only be performed when both VSMs are functioning.
Use this procedure to verify that both an active and standby VSM are in place and operational before proceeding with a switchover.
Before beginning this procedure, you must know or do the following:
•You are logged into the CLI in EXEC mode.
•If the standby VSM is not in a stable state (the state must be ha-standby), then a manually initiated switchover cannot be performed.

Use this procedure to manually switch an active VSM to standby in a dual supervisor system.
Before beginning this procedure, you must know or do the following:
•You are logged in to the active VSM CLI in EXEC mode.
•You have completed the steps in the "Verifying that a System is Ready for a Switchover" section, and have found the system to be ready for a switchover.
•A switchover can only be performed when two VSMs are functioning in the switch.
•If the standby VSM is not in a stable state (ha-standby), then you cannot initiate a manual switchover. You will see the following error message:
Failed to switchover (standby not ready to takeover in vdc 1)
•Once you enter the system switchover command, you cannot start another switchover process on the same system until a stable standby VSM is available.
•If a switchover does not complete successfully within 28 seconds, the supervisors will reset.
•Any unsaved running configuration that was available at active VSM is still unsaved in the new active VSM. You can verify this unsaved running configuration using the show running-config diff command. Save that configuration, if needed, as you would do in the other VSM (by entering the copy running-config startup-config command).
1. system switchover
2. show running-config diff
3. copy running-config startup-config
This example shows how to switch an active VSM to the standby VSM and displays the output that appears on the standby VSM as it becomes the active VSM.

Use this section to change a standalone system into a dual supervisor system by adding a second VSM.
This section includes the following topics:
•Adding a Second VSM to a Standalone System
•Changing the Standalone VSM to a Primary VSM
•Verifying the Change to a Dual VSM System
Before adding a second VSM to a standalone system, you must know or do the following:
•You are logged into the CLI in EXEC mode.
•You have the Cisco Nexus 1000V Getting Started Guide, Release 4.0(4)SV1(3) document available.
•Although primary and secondary VSMs can reside in the same host, to improve redundancy, install them in separate hosts and, if possible, connected to different upstream switches.
•When installing the second VSM, assign it with the secondary role.
•Set up the port groups for the dual VSM VMs with the same parameters in both hosts.
•After the secondary VSM is installed, the following occurs automatically:
–The secondary VSM is reloaded and added to the system.
–The secondary VSM negotiates with the primary VSM and becomes the standby VSM.
–The standby VSM synchronizes the configuration and state with the primary VSM.
The following flow chart (see Figure 3-1) is designed to guide you through the process of adding a second VSM to a standalone system. After completing each procedure, return to the flow chart to make sure that you complete all required procedures in the correct sequence.

Use this procedure to replace a standby/secondary VSM in a dual VSM system.
Note Equipment Outage—This procedures requires that you power down and reinstall a VSM. During this time, your system will be operating with a single VSM.
Step 1 Power off the standby VSM.
Step 2 Install the new VSM as a standby, with the same domain ID as the existing VSM, using the procedure in the Cisco Nexus 1000V Getting Started Guide, Release 4.0(4)SV1(3).
Once the new VSM is added to the system, it will synchronize with the existing VSM.
Use this procedure to replace an active/primary VSM in a dual VSM system.
Before beginning this procedure, you must know or do the following:
•You are logged into the CLI in EXEC mode.
•You must configure the port groups so that the new primary VSM cannot communicate with the secondary VSM or any of the VEMs during setup. VSMs with a primary or secondary redundancy role have built-in mechanisms for detecting and resolving the conflict between two VSMs in the active state. In order to avoid these mechanisms during the configuration of the new primary VSM, you must isolate the new primary VSM from the secondary VSM.
Note Equipment Outage—This procedures requires powering down and reinstalling a VSM. During this time, your system will be operating with a single VSM.
Step 1 Power off the active VSM.
The secondary VSM becomes active.
Step 2 On the vSphere Client, change the port group configuration for the new primary VSM to prevent communication with the secondary VSM and the VEMs during setup.
For an example of changing the port groups and port profiles assigned to the VSM interfaces in the vSphere Client, see the Cisco Nexus 1000V Getting Started Guide, Release 4.0(4)SV1(3)
Step 3 Install the new VSM as a primary, with the same domain ID as the existing VSM, using the Cisco Nexus 1000V Getting Started Guide, Release 4.0(4)SV1(3).
Step 4 Save the configuration.
Step 5 Power off the VM.
Step 6 On the vSphere Client, change the port group configuration for the new primary VSM to permit communication with the secondary VSM and the VEMs.
Step 7 Power up the new primary VSM.
The new primary VSM starts and automatically synchronizes all configuration data with the secondary, which is currently the active VSM. Because the existing VSM is active, the new primary VSM becomes the standby VSM and receives all configuration data from the existing active VSM.
Use this procedure to change the domain ID in a dual VSM system.
Before beginning this procedure, you must know or do the following:
•You have access to the console of both the active and standby VSM.
•VSMs with a primary or secondary redundancy role have built-in mechanisms for detecting and resolving the conflict between two VSMs in the active state. In order to avoid these mechanisms while changing the domain ID, you must isolate the standby VSM from the active VSM. This procedure has a step for isolating the VSMs.
Note Equipment Outage—This procedures requires powering down a VSM. During this time, your system will be operating with a single VSM.
Step 1 On the vSphere Client for the standby VSM, do one of the following to isolate the VSMs and prevent their communication while completing this procedure:
•Change the port group configuration for the interfaces using port groups that prevent the VSMs from communicating with each other.
•Unmark the "Connected" option for the interfaces.
The standby VSM becomes active but cannot communicate with the other active VSM or the VEM.
Step 2 At the console of the standby VSM, change the domain id and save the configuration.
Example:
n1000v# config t
n1000v(config)# svs-domain
n1000v(config-svs-domain)# domain id 100
n1000v(config-svs-domain)# copy running-config startup-config
The domain id is changed on the standby VSM and the VEM connected to it.
Step 3 Power down the standby VSM.
Step 4 At the console of the active VSM, change the domain id and save the configuration.
Example:
n1000v# config t
n1000v(config)# svs-domain
n1000v(config-svs-domain)# domain id 100
n1000v(config-svs-domain)# copy running-config startup-config
The domain id is changed on the active VSM and the VEM connected to it.
Step 5 On the vSphere Client for the standby VSM, do one of the following to permit communication with the active VSM:
•Change the port group configuration for the interfaces.
•Make sure the "Connect at power on" option is marked for the interfaces.
Once powered up, the standby VSM will be able to communicate with the active VSM.
Step 6 Power up the standby VSM.
Both VSM are now using the new domain ID and will synchronize.
Use the following commands to display and verify the HA status of the system.
