LEAP implementation Question

We are in the process of setting LEAP in our environment. We have a Nutanix three node cluster that contains our Production VM’s. We have another Nutanix three node cluster that is going to be used for DR. Right now this DR cluster doesn’t have any VM’s on it besides the Controller VM’s. Currently the DR cluster is located in the same data center as the Production cluster. Our plan is to move the DR to a different data center. What I’d like to be able to do is setup LEAP and have everything replicate prior to moving the DR cluster to the new datacenter. This would allow the process to replicate over our LAN instead of the WAN. Is it possible to set up LEAP to do replication locally like this and then once we move the DR cluster to the new data center, reconfigure LEAP so that it points to the DR cluster. The DR cluster will also be reassigned new IP addresses once it moves to the new data center.

Synchronous Replication Requirements

Hello everyone.I am planning synchronous replication between two sites with AHV, and the prerequisites are not clear in the documentation. I have 960GB SSD disks on the hosts. Apparently the minimum required is 1.2TB but it's not explicit in the documentation. Does anyone know where I can validate this information? Thanks! :)

Recover files from VM

Hi,I have a VM that the network is not working, so we will make another VM.The problem is that we need one folder storaged in the disk. Can we download this folder?I know that in VMWare you can go to the disk and copy the folder in the Hypervisor. Has Nutnix this function?Best regards,Eneko.

Snapshots like VMware

Hi there, we are new to Nutanix AHV and have one Question regarding the Snapshot feature. Is there a way to create and recover a snapshot like on VMware? I mean without having any downtime of the VM when restoring it, like in VMware?

If space is not recovered after 36 hours feat snapshot

Hello, warriors of the digital ageCould you help a beginner in trouble? https://next.nutanix.com/discussion-forum-14/snap-shot-delete-but-have-a-large-capacity-41093 https://portal.nutanix.com/page/documents/kbs/details?targetId=kA03200000098CQCAY  A few days ago, I asked about the capacity increase due to snapshots, and I was told that curation would return to normal in about 36 hoursHowever, when I checked, I realized that the capacity was not reducedIf the capacity is the same, open the case and get support from Nutanix's SREThe customer's contract has expired, so we can't get supportWhat should we do to reduce capacity? Where should I look?I would appreciate it if you could answer this question​​​​​​​​​​​​​​​​​​​​​

Automated VM export

I want to be able to export a VM in OVA format from powershell.  I suppose any script or command line function would work, but I want to automate the process.  We have a large fileserver VM with millions of very small files.  Backing up that many files is taking longer than we would like, so we ideally want to just export the VM on a daily basis and have the backup done that way.  It should be faster to do that than to have a backup process handle millions of tiny files, the overhead is just too much.I already have a script that will clone the VM and delete the VM, I just need the middle part to export the VM out of Nutanix to have that backup copy.  If I can’t get the full VM as I would prefer, I could tolerate having copies of the VM disks copied out as an automated process, to recreate the VM at a later date.  This backup copy will only be for extreme emergencies, we already have snapshots of the VM and replicas at our remote site, but for auditing purposes we need a copy of the dat

Deploying VM using OVF template/OVA file in Nutanix

I have a requirement to deploy configuration  server in Nutanix cloud for DR scenario, Azure provides OVF template to deploy this server. But as nutanix doesn’t support OVF format i have extracted OVA file to .vmdk files and created disks with it. Created a new VM and attached these disks to it. But facing VM Boot up issues. Any walkthrough for deploying VM using OVA/OVF files.

Snapshot/Recovery point/Revert-Restore from user-view

Hello all experts,I have some question about create/revert snapshot/recovery point of VM in AHV cluster:Can user (have permission to access cluster portal to clone VM, create recovery point) access and create recovery point by themselves? Can they revert/restore the snapshot/recovery point by them-self (the same as Hyper-V)? What if they request to do by themselves, what I need to do? Now I have admin permission but cannot revert, just can clone VM from recovery point.Thank you so much

NearSync not working for a particular VM

Hello everyone,I started a new project in which we need to be prepared for a Disaster Recovery between 2 Nutanix clusters in different regions. I did the Data Protection from Prism Central just fine in the beginning, already have 8 VM with NearSync enabled with RPO of 15min. However, this new VM has been giving me trouble lately, giving me a RPO up to 3 hours because of the following issues: Warning : Snapshot Replication to Remote Site is Lagging.Warning : Snapshot queued for replications to remote siteWarning : Entity is being transitioned to a lower frequency snapshot schedule. To be fair this new VM is kinda big, with 10 cores, 50GB RAM, and 1.22 TB storage used. It’s for a high transactional MSSQL Server database.I am basically stuck deciding if this is a networking problem, or a workload capacity from Nutanix problem.We are supposedly using 200MBps LAN-to-LAN networking, with a 20ms latency. Should this be enough?On the other hand, I am looking in Nutanix’s Analysis section that

I am configuring Leap on 2 remote clusters running AHV and I have performed the following :Deployed Prism Central on each cluster Enabled Nutanix Leap on each AZ Paired the 2 clusters successfully Created Protection Policies and replicated some VMs (it works properly as I am able to manually perform a restore on the target cluster)When creating a recovery plan, on network settings page, production and test failover subnets (for the remote site) are not shown and a message 'no options available' is displayed in the GUI.Please see below :  Do you have an idea of what is wrong ? Is there anything missing ?Thanks.

Backup Reports

I want to create a backup report that is sent to a specific email address everyday, which contains data protection status for the last 24 hours (both successful and failed).I have Prism Central, and have tried using the “Reports” feature. In that I have chosen a data table and configured it to show VMs in Data Protection.The report works, but I get no status about success or failed backups.I have also tried using the API, but cannot manage to get the info I want.How do you guys get backup reports/status? This is a requirement from our IT audit group, that we can show successful and/or failed backups every day.

Federation on mutilple Prism central Instances

We want to implement Nutanix Leap On premise between two clusters. The two cluster are installed on different locations (4km between the two sites).The two clusters are intented to be active, so each cluster must replicate VMs to each other (Cluster A → Cluster B and Cluster B → Cluster A)As per the documentation, we need an instance of Prism central on each site, which represents an Availability Zone.For easy management purposes, we want to be able to manage all the 2 clusters from a single pane of glass; is it possible to have a third Prism central instance to manage all these 2 clusters ?How this could be implemented?

Target-Site Protection Domain showing 0 entities

Hello, I am seeing something odd that I don’t remember to be normal. I have an Async DR protection domain replicating from a 5.20 LTS AHV source cluster to a target STS 6.0.2.5 cluster. There are a decent amount of VM's being protected today and the snapshots are replicating, but the “entities” and “VM count” on the target cluster PD page show “0” - I don’t believe I have ever seen that before and can’t find a picture in my other documents.  Is that normal? Could it be something between the versions where the target doesn’t show the VM entities that are part of the protection domain? Any help on the sanity check is appreciated. Thanks!

Backup options for Nutanix AHV VMs to VMware ESXi?

Looking to protect VMs running in production on Nutanix AHV to a DR site running Non-Nutanix VMware ESXi hardware. Currently VEEAM seems to only support “Instant Recovery” to vmware. Which seems to mean the VM is running from the backup file. I suppose at this point you could vmotion to permanent storage. Unfortunately there’s no way to know how slow this will be even if the backup repository was on the same san. Curious if there is any other backup software that makes this process a little more direct, or if anyone had expereince with this type of recovery. Thanks in advance.Currently looking at: CommVault; HYCU, scripting exporting and importing disk files, praying nothing ever breaks, crying.

Remove a disk of an external repository

Using Nutanix API, I detached a disk from a VM by just specifying device_bus and device_index.  The disk was attached from a passthru external repository.  After detaching the disk, I tries to delete the external repository, I got the following response message from delete external repository API:"The external repository hsing-ahv-test-repo hosts some virtual disks that are still in use"I could not delete the external repository.  So, I deleted the VM, but still I could not delete the external repository. Any way to remove the virtual disk and delete the external repository?Thanks

Nutanix Leap - Test virtual Network

Hello All,I have a concern about Failover test while using Async replication with On-premise Leap.For test purposes, Nutanix recommend to use a Test virtual Network that must be isolated from the Production Network. Is it a good option to create a virtual Network without any NIC bound for the test network ? Thanks.

Is It Possible To Determine Snapshots Reliability and Recovery Time?

I am aware that in snapshot entity details there is a column that tells you if the recovery status is “Recoverable”, but is this enough to be sure it will work if we use it? Also, what exactly happens if App Consistency is set as False?About recovery time, is it the same for every VM no matter the size of it? Or does it actually depend of how big/small the VM is? If the latter, is it possible to have an estimate recovery time?
