Convert Cisco 1000v from standalone to HA set-up

Recently, working on a customer environment, I discovered that their current Cisco 1000v implementation was not redundant. We quickly decided to convert the standalone setup to a HA-setup. This article shows how this can easily be done.

The current setup was a Cisco 1000v VSM (Virtual Supervisor Module) in L2 Control mode, but the same procedure can be applied to a Cisco 1000v in L3 Control mode.

Step 1. Change Cisco 1000v redundancy mode from standalone to HA (primary) on existing VSM. Confirm that role changed from standalone to primary.

1000V# system redundancy role primary
1000v# show system redundancy status 

Redundancy role
---------------

      administrative:   primary
         operational:   primary

Redundancy mode
---------------

      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

Step 2. Retrieve existing domain ID from existing VSM & Admin-password from your local password database. Domain ID can be retrieved from current primary VSM by issuing the following command. The domain ID is printed in bold. Also check the port-groups the current VSM is using as you need them in deploying the Cisco 1000v OVA:

1000V# show svs domain
SVS domain config: 
 Domain id: 1 
 Control vlan: 898 
 Packet vlan: 899 
 L2/L3 Control mode: L2 
 L3 control interface: NA 
 Status: Config push to VC successful.

Step 3. Install redundant VSM by deploying OVA (use same version as currently deployed VSM!) and choose deployment method secondary VSM. Only the relevant screenshots are shown below:

Deploy VSM OVA same version as current VSM

Choose Secondary VSM as deployment method

Choose correct VLAN's for L2 Control Mode

Choose correct deployment information

Step 4. After booting verify that the new deployed VSM is running as standby VSM:

1000v# show system redundancy status

Redundancy role 
 --------------- 
       administrative:   primary 
          operational:   primary 
 
 Redundancy mode 
 --------------- 
       administrative:   HA 
          operational:   HA 
 
 This supervisor (sup-1) 
 ----------------------- 
     Redundancy state:   Active 
     Supervisor state:   Active 
       Internal state:   Active with HA standby 
 
 Other supervisor (sup-2) 
 ------------------------ 
     Redundancy state:   Standby 
     Supervisor state:   HA standby 
       Internal state:   HA standby

And voila, the set-up is redundant now! It’s as easy as that.

Note: Don’t forget to configure the proper VMware DRS rules in order to separate the VSM’s.
