ESXi VMs not recognized in Veeam after async DR failback
We are running asynchronous Protection Domains and also employee Veeam backups of VMs. If we failover to the secondary site and then failback to the primary site, Veeam no longer recognizes the VMs in previously created backup jobs. We have to delete all the old backup jobs and set them up again. This is with ESXi hosts. Is that normal?
Automate in-guest script execution on the guest VMs during recovery (NGT)
Hi can someone know the script to change the computer name during recovery plan. This is our script, everything is working except the script to change computer name. Thank you. netsh interface ip set address name="Ethernet 4" source=static ^ address=x.x.x. mask=255.255.255.0 gate=x.x.x.xnetsh interface ip set dnsservers "Ethernet 4" static x.x.x.xtimeout /t 10 /nobreakWMIC computersystem where name="computername" call rename name="newcomputername"shutdown.exe -r -t 00
Nutanix VM restore is failing if backup proxy scsi is not in order
Hi All, We are using third party backup solution for VM backup and restore of prism api version 2. If my third party solution installed vm scsi is not in order(scsi.0,scsi.1,scsi.3). If they are NOT in series, like local disk are scsi.0, scsi1, scsi.3 (scsi.2 is not there) Hot-added restore disk will be assigned ID scsi.2 as raw backup restore disk. As script assumes that restore disk would disk after scsi.2 and NOT confirm actual hot added disk could be scsi.2, it removes scsi.3 instead of scsi.2.
Nutanix data protection failover failback question
Hello Techies, I am a bit new to Nutanix and in my environment we have bunch of protection domains configured. Some are configured to replicate 1 minute and some are replicating at 1 hour interval. hosts are running VMWare ESXi 7.x versionsThe appropriate replication schedule has been configured in each protection domain at primary site. My question is as below:In a DR exercise(planned failover and both sites are available), if I failover the protection domains to our DR site, I am aware its basic functionality that the VMs will be powered off at primary site and we need to manually power them on at the DR site.Now, suppose VMs are running on DR site, will VMs start the reverse replication(from DR site to primary site) automatically to primary site's protection domain?or do I need to manually create replication schedule at DR site ?Do I need to remove the inactive protection domain at primary site? How do I make sure we won't have any data loss during the failback operation?I am confus
To Dr-site Replicaton be suspended.
Hello Data replication, which was well done until yesterday, has stopped and is not progressing. Only one of the five scheduled schedules will be suspended. Note that the three entities that correspond to the schedule are excluded from the schedule for a while. After increasing the cpu and memory, I included it again. Is there any part or command I need to check? This is a dark site, so remote assistance is not available. Help me.
Metro Container Storage Missmacht
Hey guys,I made a quite new discovery that is totally new to me and I try to understand where this is comming from, maybe someone can help :)Scenario: There are 2 ESX clusters, connected via Metro. The DataStore on the source site is ~2TB, the datastore on the destination is about 1TB and I have no clue why :)Both DataStores only use compression, there are no other snapshots on the source side and this is for a couple of days now, so no curator run should be involved. Ideas anyone? Cheers, Flo
My cloud connect question was closed without explanation
I opened a thread a month ago about Cloud Connect S3 consumption and when checking on it today I found that it was closed to comments.https://next.nutanix.com/nutanix-disaster-recovery-29/aws-cloud-connect-s3-consumption-issue-41499?postid=63137#post63137There was no explanation for this action in the thread or via PM to me. Can someone let me know why this was done?
Creating SQL Server HA cluster with DR
Hi,I have two Nutanix clusters on different sites (one on each site) a few miles apart with 10GB low latency networking in place.I have setup a two node failover SQL Server cluster for HA on a single site, but I would like to add DR to the solution.I know Availability groups (and other options) are a good solution for this, but we can’t implement those at present and so I am looking for the ‘correct’ way to replicate the two node HA that we have (With it’s shared storage) across to the second site so that our front-end application will continue to function in the event of a site failure.Any tips or pointers would be very much appreciated!Thanks
Two-Nodes Cluster Replicate to One-Node Cluster
Hi,We have two locations and want to install Two-nodes-Cluster in the production location and One-node-cluster in the Disaster Location and to replicate these clusters each other. My question is:Can we connect two-nodes directly with 10 Gbit DAC SFP+ cables each others? So, Is physical switch necessary to install two-nodes-cluster? We want to use Direct Connection (via DAC Cables) for RF2 data replication between two-nodes and 2 x 1/10 Gbit Base-T port will be using for VMs connection and replication VMs to one-node-cluster in the DR site. Is this scenario possible? What about fail-back scenario? (back from DR to Production)Notes:We have 3 x NX1175S G8 Nodes We want to use AHV or ESXiThanks.
Nutanix Data Protection about Three Sites in Two Places
Hello guys,We are considering upgrading the existing Nutanix cluster environment to meet high reliability protection for critical applications.Currently we have a site A as the production cluster and site B as the disaster recovery cluster. The sites on both sides use Leap to provide a data protection strategy with an RPO 15 Mins.All sites' virtualization systems are using AHV.Now we plan to build a new site C, and do real-time synchronous data transmission with site A.Site A and Site C will be deployed in the same building.At the same time, it is hoped to ensure that the failure of either site A or site C will not cause data loss or service interruption.We hope to use Nutanix's data synchronization solution.However, we found that once the VM uses Leap to configure the real-time synchronization policy, the original Leap asynchronous transmission policy cannot be applied.It appears that only one Leap protection policy can be applied to the same VM.Therefore, based on the above situation
Is the Nutanix Hybrid Cloud Reference Architecture available anywhere else?
Hello guys,I’ve been meaning to take a look at the Hybrid Cloud reference architecture PDF but it’s been unavailable for months:https://www.nutanix.com/viewer?type=pdf&path=/content/dam/nutanix/resources/misc/private-cloud-reference-architecture-tech-note.pdfDoes anyone have an idea where I could get it?Thank you
AWS Cloud Connect S3 consumption issue
We bought several Nutanix clusters in 2019 and on two of them, we deployed a cloud connect appliance in AWS via Prism element so that we could backup our VMs to the cloud. We setup retention to 7 snaps locally and 62 on the remote (AWS) side. The question I have for everyone that uses Cloud Connect for backups is, does the S3 bucket that gets created by Cloud Connect ever stop growing in size. On our HQ Nutanix cluster, that Cloud Connect S3 bucket is currently sitting at 164TB and 177 million objects. This is a small 3 node cluster with only 10 VMs being backed up to the Cloud Connect appliance. Current allocated space for those VMs is 3TB. Actual consumed by them as reported by Prism is about half of that. Looking at the S3 bucket created by cloud connect, I see that a lifecycle rule was created to move objects to infrequent access after 30 days. I see nothing to expire old objects and there are objects in the bucket dating all the way back to 2019. So at first glance, it doesn’t loo
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.
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! :)
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
