At a customer we have a single Nutanix 3-nodes Cluster running like a charm for a few years. All virtual machines are snapshoted by Prism, 3 times a day, and then replicated to a remote backup site which is Microsoft Azure. In Azure we have then a CVM and some blob storage to store backup replicas.I’m currently wondering our possibilities if a severe outage occurs on the site hosting the physical cluster leading to the loss of the hardware.I know that we could order a new physical cluster and then retrieve the snapshots externalized to Azure to rebuild the infra, but it means that the infra is down for a few weeks (supply time, etc...).Is there a possibility to restore externalized snapshots directly to Microsoft Azure VMs?
Nutanix recommends the following best practices for implementing disaster recovery using Leap. Along with these recommendations, there are specific recommendations for data protection with Synchronous replication (0 RPO).For data protection with Synchronous replication recommendations, see Recommendations for Synchronous Replication.General Recommendations Create all Leap entities (protection policies, recovery plans, and VM categories) at the primary site, where the VMs exist. Upgrade the Prism Central before upgrading the Prism Element running on the clusters registered to Prism Central. Disable Synchronous replication before unpairing the sites.If you unpair the sites while the guest VMs in the Nutanix clusters are still in synchronization, the Nutanix cluster becomes unstable. For more information about disabling Synchronous replication, see Disabling the Synchronous Replication (from 5.12 to 5.17 only). Recommendation for Virtual NetworksDo not create virtual networks that hav
On Nutanix cluster , our Oracle workloads are protected via Oralce Data guard. We are looking for some sort or block level replication solution to cut down the Oralce license cost for DR solutions.Does Nutanix or 3rd party application that work on Nutanix cluster have any DR replication (block level) solution for Oracle and SQL server workloads with point in time recovery?I don’t think the protection domain is suitable for Database workloads. Please suggest DR replication solution available for VMs that runs Oracle/MSSQL database workloads.
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
I’m new to Nutanix and we are using Prism Pro to move a VM from one 6.7 Vmware farm to another and back again. That works 100% but Veeam V11 can not see the VM once it is moved. It’s like the UUID is wrong but I have checked that and it is ok (same) Support are looking into this and are saying this is a unique case… surely this must be common? If there is no solution we will end up with the same VM added to the Veeam backup job, again and again… I have tried using TAGS and direct add to veeam…
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.
I just want to know if there's a downtime on my Virtual Machines, for example my Main site have an outage then I have remote snapshots to DR site. The question is . . . is it automatically activated or powered ON my virtual machines inside on my remote snapshots or I need to manually activated or powered ON the virtual machines on my remote snapshots?
I have a question about PD snapshot frequency.Referring to below link, a node with 32-64 TB HDD tier support NearSync and hourly snapshot with specify requirement (e.g. 14vCPU for CVM).Node Configurations for Snapshot or Recovery Point FrequencyIf I have a 64TB HDD nodes with 2 x 12 cores CPU, the CVM will configured with 12vCPU after foundation. Does it means that node not supporting hourly snapshot and NearSync?
I have a problem about Recover VM in Rubric. I have made several attempts to recover the vm.As additional info:1. The VM is in Nutanix, previously the SATA storage bus and has been converted to a SCSI storage bus2. Nutanix has been upgraded AOS version 220.127.116.11 LTS NCC version 18.104.22.168 Foundation version 5.0.4-ed564a883. RUBRIK has been upgraded to version 5.3.3-19316
I have question about remote site's snapshot.When we restore the VM by snapshot from origal siteI have question about remote site's snapshot.When we restore the VM by snapshot from origal siteWhen we restore VM, it will probably be a clone of the original site's VM, so I can understand NIC MAC Address can be changed.However, I hope to know does IP addresses also be change or not.
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.
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?
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
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.
Hello everyone!I read on this blog about end-to-end encryption that encrypting all replication traffic between all AOS clusters participating in replication.I want to know about end-to-end encryption on DC-DR replication.Where can I see the full documentation about that (in what features and how do I configure it)?
Our 5-node Nutanix Mine with Veeam is using the default 75% as the watchdog capacity.The Nutanix Mine administration guide mentions paramters associated with this:restart_jobs_threshold_percentcancel_jobs_threshold_percentstop_issuing_jobs_threshold_percentand advises customers should contact support if they wish to tweak these.My question is this: Which organisation’s support covers this? Veeam or Nutanix?
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 22.214.171.124 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!
Hello,I’m using Commvault to back up our Nutanix file server cluster. I have a distributed share that is failing with the following error:4788 26ec 07/19 16:25:38 271 CTREE rebuild failed with error 652 (duplicate keys rejected and listed); sysiocod=0 4788 26ec 07/19 16:25:38 271 CTREE resumeAndRebuild: unable to rebuild indexAny ideas?
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
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
