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?

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.  

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.

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”.

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,

In addition to data compression and data deduplication — features that are expected nowadays to be present on any storage aware platform Nutanix AOS also offers Erasure Coding. For workloads with cold data present (no write within past 7 days), when enabled, EC encodes a strip of data blocks on different nodes and calculates parity. In the event of a host and/or disk failure, the parity can be leveraged to calculate any missing data blocks (decoding). In the case of DSF, the data block is an extent group and each data block must be on a different node and belong to a different vDisk. Once parity is computed, the data block copies are removed and replaced with the parity information. Workloads Recommended for Erasure Coding Write once, read many (WORM) workloads.

Hello i am a developer who develops through nutanix api i Want to know about api roadmap i found out by chance that urlhttps://www.nutanix.dev/2019/01/15/nutanix-api-versions-what-are-they-and-what-does-each-one-do/ when i read that page, i feel curious about api roadmap in nutanix      1. when v2.0 api is advanced, v0.8 or v1.0 is deprecated?      2.  when i want to use migrate or snapshot function, i have to use v0.8 api? will some functions(like migrate) continue to be categorized in v0.8, v1.0 and v2.0?  and if i get some document about v0.8 api, i want to get them i wait for your answer  thank you     

 Most of our customers upgrade their infrastructure once every couple of months and this guide helps our customers understand  how to upgrade and what to expect from the process. In older versions of AOS, upgrades were done using “one click” or “upgrade software”. With LCM available in newer versions, the upgrades are much simpler and straightforward. Here’s the documentation  to understand pre-requisites of LCM and how LCM works:https://portal.nutanix.com/page/documents/details?targetId=Life-Cycle-Manager-Guide-v20:Life-Cycle-Manager-Guide-v20 The LCM works on one-node at a time and if the upgrade proceeds to the next node if the scheduled node is successful in upgrading to the target version.

Hi All, I’m sorry because couldn’t find related k/b on mixed nodes compatibility/requirements in details.  Just wondering current latest platform supported for mixed nodes with different OEM hardware model in same cluster? For example: Existing we have 3 x HPE DX360 in same cluster and would like expand with different hardware model/family such as Dell XC family/NX family or HPE higher model like DX380 in same cluster? Appreciate it in advance. John.

Is anyone experiencing random RDP issues to VMs on Nutanix?I’m experiencing random authentication errors when connecting to Nutanix VMs.It’s not the RDP setup as sometimes it works.Is there an setting on Nutanix that might be causing this?

Hello,I have 2 questions about Storage:Can someone please explain the Deduplication option when setting up storage containers. Is this necessary or recommended? What is the purpose of a Volume Group? Currently we use the whole default storage container for creating disks and dividing out storage to servers. Recently some users have wanted to reserve a few TB for video use and storage. I created a new “video” storage container tapping into the default container for the space. So when I attach the disks to the servers, I pull from this specific container. Would creating and using a Volume Group be better? I don’t understand the purpose of it.ThanksBrent

Hi Everyone,One of the nodes of our cluster suddenly got disconnected. I was not able to ping initially, but after restarting the node and checking if maintenance mode is enabled. Connectivity was regained and all the IPs can be pinged from each other.  Even so, the cluster can’t recognize the previously disconnected node even when all pings are good. Tried restarting the cluster and the local CVM but the error below appears:nutanix@NTNX-A-CVM:192.168.50.182:~$ cluster status2021-07-13 07:34:46,652Z WARNING genesis_utils.py:1304 Failed to reach a node where Genesis is up.
