Nutanix Disaster Recovery

Hi.Currently, virtual machine A running on cluster A (consisting of three machines) is being remotely backed up to cluster B (consisting of one machine) using Prism Element's protection domain.In this state, is it possible to remotely back up virtual machine B running on cluster B to cluster A using the protection domain?Is this a problem?kind regards.

Our current setup is physical prod servers and VMs are in 10. 172.31.40.1 segment and DR physical servers are in 172.31.30.1 segment and DR VMs are in 10. 172.31.40.1 segment and we configured Async DR setup. Currently we configured IPsec VPN in HQ and DR through FortiGate firewall. If production site  down, how can we access the production VM servers in DR site. This is our concern please provide solution for this design.

I’m configuring Nutanix DR with zero compute but when i try to deploy MST from marketplace i receive the following errors:Credential is invalidVariable new_secret_keySecret value for variable is emptyVariable new_access_keySecret value for variable is emptyCredential default_credSecret value for credential is emptyI’ve tried to configure default credentials from self service but with no luck.thanks in advance

Hi everyone,A customer currently operates a VMware vSAN cluster at their primary site and is planning to deploy a new HCI platform at a secondary site. One of the key requirements is that the new HCI cluster must be able to replicate workloads to the existing VMware vSAN environment.My question is the following:Is it feasible to propose Nutanix with AHV for the secondary site while keeping VMware vSAN at the primary site? If yes, which third-party solution would be recommended to ensure reliable replication between Nutanix AHV and VMware vSAN? If not, what alternative HCI architecture would you recommend to meet this requirement? Thanks in advance for your insights and feedback.

Hello,First post here!I previously developed an automation flow using the Nutanix V3 API that interacts with Prism Central and orchestrates the "Test Failover", "Failover" and "Clean Up" DR Actions for a specified list of Virtual Machines.For the V3 API version, I utilised both the "recovery_plans" and "recovery_plan_jobs" API endpoints.These do not appear to be present within the V4 API (not that I can find in the various V4 API documentation).Are there plans to add these and if so, are there any timescales for when these will be added?Thanks.Regards,Paul 

I am working on setting up DR replication between two 3 node Nutanix clusters running AOS and AHV. Can someone help clarify something for me? It does not appear that you can replicate a PC VM, and the clusters can only be registered to a single PC instance. So:If the cluster hosting the PC VM were to go down, how would you be able to initiate a manual failover with the controlling PC VM also down?Do I need to stand up PC on each cluster and register each to a separate PC instance to avoid this single point of failure?Is bi-directional replication possible with two clusters registered to the same PC? It appears that once a protection policy is setup to replicate from cluster A-->B that A is no longer an option to setup as a replication target from cluster B.

Hi. It appears that you cannot backup PC to an AWS storage gateway, it must be able to reach AWS natively. Is this true? Thank you!

Hi everyoneI have to deploy a Metro Availability architecture for two AHV clusters (no ESXi involved) and I have several questions so I’d appreciate some feedback from those who have deployed similar setups. The main goal is to achieve the lowest possible RPO and RTO between two datacenters with a robust and simple architecture. Both clusters will be separated by about 100m on two separate buildings and they will be connected with FC cables (<5ms).As far as I know, only ESXi with vMSC supports true RTO = 0 However, since this environment is AHV-only, my understanding is that in a failover event the VMs from Site A would need to be powered on in Site B rather than running continuously on both sides... Is that correct?That being said, here you are the possible scenarios to deploy Metro Availability between both sites: Two AHV clusters in

With the Starter license, am I able to configure asynchronous replication in both directions— from site A to site B and from site B to site A?

Hi,Thoughts from the community please on this one.We have two clusters, in two different data centers with NearSync to replicate VMs.  So my problem is when I do a unplanned fail-over I get a VM with a new GUID, all good, until my backup software (Veeam) sees this as a new VM and creates a fresh full backup.  How do I deal with this in a better way? A full backup of all my VMs is going to need a lot of space and time! 

I’m setting up my DR site, will be using asynchronous/near-sync replication with Protection Policies in Prism Central (NOT Protection Domain) I don’t want to completely drown my WAN link in replication traffic during the initial VM seeding. Is there any way of throttling or controlling the replication traffic?

Hi,I need some clarification regarding the following scenario:We have an on-premises infrastructure running on Nutanix with AHV as the hypervisor. Our goal is to replicate these virtual machines to Microsoft Azure to establish a disaster recovery (DR) setup.Is Nutanix AHV fully supported for replication to Azure in the same way that VMware or Hyper-V environments are supported by Azure Site Recovery (ASR)?Could you please help clarify the possible options, associated challenges, and the feasibility of replicating Nutanix AHV workloads to Azure—particularly through ASR or any alternative solutions? I’m looking for clear insights and confirmation on the best approach for this use case.Thank you.

Hello, I’m new to Nutanix and setting up DR for VMs on vSphere ESXi.While failover from primary to DR site is straight-forward, I was wondering on the amount of time for failback. Normally, when failback is initiated, it will replicate changed blocks from DR site to primary site.And this may take a while depending on the changes occurred while at DR. Is it possible to do reverse replication while still at DR? This way, when failback is initiated, only the few remaining changed blocks need to be replicated - shortening the failback time.Thanks for your comments

Recommendations for DR Configuration between On-Prem AZsRecommendation for Virtual Networks• Recovery plans do not support overlapping subnets in a network-mapping configuration. Do not create virtual networks that have the same name or overlapping IP address ranges.Quotes from Nutanix Disaster Recovery Guide I would like to clarify the meaning of the recommendation point (Recovery plans do not support overlapping subnets. / Do not create networks that have the same name or overlapping IP address ranges.). Kindly, provide a simple example for clarification, if necessary.

Hello everyone !I have lost the entire administrator access to my Nutanix CE infrastructure exepted to AHV. I cannot log to my CVM by SSH and cannot log to the web interface of Prism Element ( Account locked due to too many failed attempts.). I also do not have backup account, only the admin one with wich I’m trying to log.I have access to the IPMI of my server and can log to AHV on it, if someone has any idea how i can regain control I would deeply appreciate itThanks in advance

Hi,Is there a way to query which cluster that a VM is running on from within the VM itself?   I will need this for both Windows and Linux VMs. The reason is I want to take different actions in the Data Protecion Recovery Plan scripts production_vm_recovery and test_vm_recovery depending on which cluster the VMs failed over to.  Thanks,Howard

Hi. We have a Nutanix server with Qilin (AES-256/RSA-4096) ransomware incident. The server is compromised, so we extracted the physical disks apart. Someone can give details or links to reconstruct a virtual filesystem as a single raw ext3, ext4 or qcows2 filesystem to run autopsy or et. al. We have the tools, the experience, the equipment but we do not have the knowledge nor the tools to convert from ADFS distributed cloud filesystem to single volume / disk filesystem as extX, vmfs, LVM, … Nutanix server has 3 nodes, each node with 3 hard disks, so, it seems an RF=2 configuration. And please avoid suggestions as contact attackers, contact specialists, contact someone else, use the same server, use recoverit, recuva, testdisk ... We are the specialists and need help to deal with ADFS offline

Hello Community I’m having an issue with some of my VMs post failover support has not been able to help me. We have a local cluster and a remote cluster. All of our VMs have static IP addresses. When I execute a failover the VMs receive new IPs as expected. 70% of the VMs will have the IP, Subnet Mask, Gateway and Primary/Secondary DNS populated for the IPV4 on the NIC.The other 30% will only have the IP, Subnet Mask and Gateway populated. The DNS settings are left empty. It is always the same VMs that have the issue. We have done a ton of troubleshooting so I can’t list everything that we have tried. Is anyone else having this same issue? If so, is the solution to just use custom scripts and deal with the issue? 

When configuring a protection policy for synchronous replication between two Nutanix on-premises availability zones (AZs) without utilizing a witness VM, under the Failure Detection Mode setting, in what scenarios should Manual Mode be used, and when is Automatic Mode recommended and that related to witness service?  

If I have two AHV clusters distributed across a primary site and a disaster recovery (DR) site, and I configure Metro Availability between them, is it possible to deploy the Witness VM at the DR site?

I have 2 AHV clusters (3 nodes), and if I want to configure synchronous replication between them, I have two options: Sync Replication and Metro Availability. I would like to understand the key differences between these two approaches and the specific features. Note that I will not use a Witness VM.

Hello, I have a question about the functionality of VM replication between two clusters (Nutanix metro).I would like to know if my virtual machines defined on the main cluster can start identically on the backup cluster in the event of an incident. In fact, my question is more focused on the software and OS licenses that are implemented on the VMs. That is, are the licenses also replicated, or does it depend on the type of license?Best regards,
