Nutanix Insights

Nutanix includes a set of features known collectively as Insights that provides a predictive health and support automation platform. Insights dynamically analyzes the extent to which you are following best practices in configuring your clusters for long-term reliability, availability and performance. Insights provides Predictive trends and analytics Guidance for optimal configurations Application best practices Seamless automation support Insights is available only for clusters with Pulse enabled. Workflow: Pulse collects cluster data and sends it to Nutanix customer support. The pulse data goes to the Insights engine, a SaaS-like service in the cloud, that goes deep analytical processing of the Pulse telemetry and identifies potential issues based on findings or patterns in the data.

What Host is a Windows VDI running on when running on AHV

Hi,We’re currently moving from Nutanix Hyper-V cluster to a Nutanix AHV cluster. We’re running Windows 10 VDIs on these clusters, currently we use BGInfo to display various settings for our users (VDI name, IP Address, Host Name). On Hyper-v it creates a registry key on the VDI with the Host that the VDI is running on. Does anyone know how i fins this information when running on a AHV cluster..?Thanks

ISO imported into Images have no size can't mount as CD

Read beginner question, but I don’t understand what’s going on.Often I’m asked to create a VM and boot from an ISO. But often, when I add the ISO to the Images, it’s added somehow broken. It has no size, and attempting to mount it as a CD/DVD doesn’t work- because that image is not available to be chosen- it’s not in the list.The images list starts off like this. There’s two Linux isos that are fine, and some Server 2016 ISOS that work fine.Name Description Type Size Creator CentOS-8-Full CentOS 8 (Full ISO) ISO 7.67 GiB - en_windows_server 2019 v1909.iso Server_2019 ISO - myself@somewhere.com Fedora-Workstation-Live-x86_64-34-1.2.iso Fedora Linux 34 ISO 1.87 GiB myself@somewhere.com But the ISO i was given and told was the installation ISO for Server 2019 doesn’t seem to be that.

Ransomeware recovery for Nutanix

I wanted to see what other people in the Nutanix community are doing in regards to plans to recover from Ransomware for VMs that run on Nutanix and Files on Nutanix Files file servers? I have heard that the snapshots in Nutanix are immutable is that a true statement?

Migrating Guest VM From A Protection Domain To A Protection Policy

You can protect a guest VM either with a protection domain in Prism Element or with a protection policy in Prism Central. If you have guest VMs in protection domains, migrate those guest VMs to protection policies to orchestrate their disaster recovery using Leap Migration from protection domains to protection policies is a disruption process. For successful migration, Ensure that the guest VMs have no on-going replication. Ensure that the guest VMs do not have volume groups. Ensure that the guest VMs are not in consistency groups. To migrate a guest VM from a protection domain to a protection policy manually, perform the following procedure. Procedure: Unprotect the guest VM from the protection domain Do not delete the guest VM snapshots in the protection domain. Prism Central reads those guest VM snapshots to generate new recovery points without full replication between the primary and recovery Nutanix clusters. If you delete the guest VM snapshots, the VM data replicates

Continuously Enable Shares ( SMB Only)

Persistent file handles facilitate continuous availability (CA) for SMB shares. During the disruption of service, SMB shares remain continuously available by using the persistent file handles and the high-availability features. Persistent file handles reduce the period of data unavailability by automatically reconnecting users to the file service in-use before the disruption. Files store open lock information on persistent volume groups available for every FSVM in the cluster. During a fail-over, the fail-over FSVM can access the volume group. Persistent file handles let clients wait to reconnect without notifying the user about the connection failure. As a result, disruptions are seamless to users and applications. During a lock protection interval, Files does not prevent NFs clients from accessing the file. Files only prevent SMB clients from accessing files during the disconnected state. The periodic handler cleans up stale locks for the disconnected persistent file handles every 24

Query RE Async Replication Conditions

We have 2 Nutanix clusters running with the ESXi Hypervisor. We’re using Metro availability to replicate datastores\containers between clusters. We’d like to replicate some of the VMs that reside in these Metro enabled containers over to a potential 3rd site. We were thinking to use Async replication for this.Is this possible and is it supported?I ask this because in the “Conditions For implementing Asynchronous Replication” guidelines there is a condition that states “Multiple protection domains cannot protect the same VM. Configure one protection domain to protect a VM”.

CVM shutdown error

Let's say you want to shut down a CVM for maintenance, firmware upgrade or any other reason, and when you run "cvm_shutdown -P" you get this error: "StandardError: Cannot connect to genesis to check node configuration status" If you have an older version of AOS (5.5.x or 5.6.x) then the shutdown script on your CVM might need a small modification, you can contact Nutanix support and an engineer will edit the file on the spot, or you can upgrade the AOS to a newer version which has the fix. If you have a newer version and you want to shutdown a node in the cluster, make sure that you follow the correct shutdown process depending on your hypervisor, here are the instructions for each: AHV, ESXi, hyper-v or Citrix. You can also check out KB-3270 for the cvm_shutdown script.
