Zerto VPG Failover

This is Blog 5 of 5 on Zerto Replication.  This blog will cover how to do a “Failover” for a Virtual Protection Groups (VPG).  First, let’s recap where  we are.

  • ZVM has been installed at both sites
  • The sites have been paired
  • VRAs deployed at both sites
  • VPGs have been configured and replicating
  • VPGs have been tested with a test failover

So now Zerto is up and running 100%.  We are now ready to failover VMs in the event of a Disaster Recovery Scenario. 

Go to the VPG you want to failover.  In the bottom right-hand corner move button to “live” and select the failover arrow.

Select the VPGs you want to failover and select next

 Image

 Here you will select your “Commit Policy”, “Shutdown Protected VMs” and the “Checkpoint” of your choosing

Image

You are now ready to execute the failover process.  The failover starts, by creating the virtual machines in the recovery site to the point-in-time chosen in the previous step.  Finally the data is promoted from the journal to the VM and the failover is complete.

Image

As you can see the LABWIN7VM1 has failed over to the DR cluster

This concludes my series on Zerto.  I hope this blog series has been helpful and showed you how Zerto can be a great asset for your disaster recovery needs.

Zerto Virtual Protection Group (VPG) Test Failover

This is Blog 4 of 5 on Zerto Replication.  This blog will cover how to do a “Test Failover” for a Virtual Protection Group (VPG).  This is a great feature where you can test your DR site at any time without causing any interruption in your production environment. First, let’s recap where we are.

  • We have installed ZVM at both sites
  • The sites have been paired
  • VRAs deployed at both sites
  • VPGs have been configured and replicating

So now we are ready to “Test Failover” the VPG.

1. Go to the VPG you want to failover.  In the bottom right-hand corner make sure the “Test” feature is selected and not the “Live”.  Then select the “Failover” arrow.

 Image

2. Make sure the VPG you are testing is checked and hit next

Image

3. The “Configure” option is where you select the bookmarks or point in time you want to use. Select the checkpoint option.

 Image

4. Here you select you Recovery Point options.  I will pick the Manual Select Option.

 Image

5. Then you can select the Point-in-Time based on your journal settings you chose earlier in the setup

Image

6. Now you are ready to test the failover by clicking the failover arrow

 Image

 7. Go back to the VPG and once Zerto and VMware have completed the failover you will be presented with this screen.  You will see in the upper right-hand corner that the VPG is in Test mode as well as the green check at the bottom-left of the screen beside “fail over test”.  Now you can test your VMs on the “Test” network you defined earlier.  During “Test mode” you can initiate a true failover if something happens during that time.

Image

8. After you have completed you’re testing its time to stop the failover test by selecting the “Stop” symbol in the upper right-hand corner.

 Image

9. The Stop Failover Test screen will pop-up.  Select the VPG and select the “Stop Selected” option.

Image

10. Once Zerto and VMware have taken down the test VMs and a green check will show up beside “Stop Failover Test”.  Now your VPG is back to normal.

Image

This concludes this blog on failover testing for a VPG.  My final blog in this series will go over an actual failover.

Zerto Virtual Protection Groups (VPG)

This is Blog 3 of 5 on Zerto Replication.  This blog will cover how to create Virtual Protection Groups (VPG).  A VPG is a group of VMs that need to be grouped together for replication purposes.  An example would be an application server and a database server.  A more specific example would be an instance like Microsoft Exchange.  Typically you have 2 to 3 servers for Exchange (Database, Software and Web) and they need to be in sync at all times.

What you need to have in place before you Create a VPG

  • ZVM at both sites
  • The sites paired
  • VRAs deployed at both sites
  • VPGs already planned out

1. Login to Zerto.  Every tab in Zerto has the “New VPG” option at the top right.  Select New VPG

Image

2. There are several setting that you need to set here. First off you want to name the VPG

Right Side

  • Target Site – The site you are replicating to
  • Host – The Host you want the VMs in the VPG to reside on.  You also have the option of selecting a cluster
  • Datastore – Target Datastore for the replicated VMs
  • Failover Move Network – The network you want the VMs to use in the event of a failover
  • Failover Test Network – The network you want the VMs to use when test your VPGs.  The idea is to be able to bring up the replicated VMs in a “Test bubble” or isolated VLAN so that there is no production issues during testing.
  • Folder – The organizational folder you want the VMs to be in

Left Side

  • Priority (QOS) – The priority of the VPG
  • Target RPO Alert – The maximum time between each automatic checkpoint being written to the journal before an alert is issued.
  • Default Journal History – The time for which all write commands are saved in the journal
  • Test Frequency Reminder – How often you want to test your VPG.  If you don’t reach that time period you will get an alert
  • Wan Compression

There is also an option for recovery scripts at the bottom

 Image

3. After all that is completed then you can add your VMs to the VPG

Image

After your VPG is complete you can select it and monitor the progress of the initial Sync and review the mapping of resources to DR.  Overall a simple process.

The next blog will discuss Testing a VPG as well as a VPG failover

Zerto Replication Appliance Deployment

This is Blog 2 of 5 on Zerto Replication. This blog will cover pairing 2 different sites as well as installing the Zerto Virtual Replication Appliance (VRA). This is needed for replicating VMs from one site to the other.

Recommend prerequisites for VRA
• Have the ZVM already installed at each site as well as have them paired
• 1 VRA per ESXi host at each site
• Have your network, IP addresses and storage ready

I would like to point out one of the cool features of Zerto, the VMware Plugin for the vSphere client. You can access Zerto without having to login through a Web Browser by selecting the Zerto Tab.  It is installed automatically after ZVM has been deployed.

 Image

 Pairing the Sites

1. Once you are in Zerto go to the summary tab and select “Pair”

Image
2. Select the “Add New Site” in the upper right hand corner

Image
3. Add Site

Image
4. You will get a Green Check once it is complete. Then you will be able to see the DR site in the “Sites” tab as well as the “Topology” Tab.

Image

Image

Image

Installing the VRA
1. To begin replication you need to install a VRA at both sites. Select you ESXi host and then go to the “VRAs” tab and select “actions” and then “Install”.

Image
2. This is where you put in all of your settings for the VRA

Image
3. The VRA will initialize. The ZVM will deploy a virtual appliance with the settings you put in. Once the VRA is initialized you are finished.

Image

Lets Recap Zerto so far:
• We have installed the Zerto Virtual Replication Manager (ZVM) at both sites
• Paired the sites
• Installed the Zerto Replication Appliance (VRA) at both sites

The next blog will cover Virtual Protection Groups (VPG), which is the last step for setting up recovery with Zerto.
