My customer ask me about how to config vm power on sequence when start cluster Example Domain Controllers power on firstExchange Server power on secondApplication Server power on thirdMy customer have only PE.Thank you for answer the questions.

Do you think is there any way i can migrate data from standalone server to the AHV?

I want to transfer Prism Alerts, Events logs to another log collection server. A log collection server is a solution called innerbus. How can I send it?

Hi,I have three identical nodes (basic Lenovo servers) but one performs really slowly compared to the others. The disks aren’t the same across all three though. I wonder if anyone has any ideas which difference might be causing the performance issues: Firstly the HDDs are 4TB in the two ‘good’ nodes and 2TB in the ‘slower’ one. I wouldn’t expect that to cause performance issues, just overall capacity will be limited? To be fair the 2TB is a WD ‘green’ and the 4TBs are WD ‘red’ drives. Secondly the ‘slower’ host has a Samsung Pro 840 256GB SSD which Prism reports as often having a higher latency than the HDDs! See the image below  Are they known for being poor in this kind of environment? I’m not really stressing them. Any good logs to see performance issues? I can see the HDD activity light i

Beside the “classical” Monitoring with snmp or agent based version now we are talking about Metrics and the Monitorng of LiveData with the OpenSource Project Prometheus. The Virtualization is made with the powerfull Tool of Grafana.The access to the Data will be made with so called “Node-Exporter” which could we found under GitHUB. One is present for Nutanix! My Testcase in the homelab is build with the following items:NutanixCluster <- Prometheus <- Grafana192.168.10.80 192.168.10.123 192.168.10.100Nutanix CE Ubuntu 18.04 LTS Ubuntu 18.04 LTSPrometheus 2.2.1 Grafana 7.0.4GO 1.10RequirementsCreate NEW User i

This is a continuation of the post that I wrote here: https://next.nutanix.com/topic/show?tid=33950&fid=31 Part of this was resolved however we are still running into an issue with some of our VMs in which they get stuck in this state: { "status": { "description": "2016 Template-4/17/19", "state": "ERROR", "execution_context": { "task_uuids": [ "8d0c2110-461b-4252-a223-11016ff8714b" ] }, "message_list": [ { "message": "Edit conflict: please retry change. Entity CAS version mismatch.", "reason": "CONCURRENT_REQUESTS_NOT_ALLOWED" } ]} The only way to clear it is to power the VM down and update the VM within the GUI.  However, upon trying to subsequently update the VM by API it results int the same error. Please advise

Hi All, I am a beginner to Nutanix, just wanted to AHV / AOS! how its function.

Im trying to create a playbook that on X alert posts to teams channel…. is this possible? I have tried a few methods but not having much joy. Method: POST  URL: https://outlook.office.com/webhook/blahblahblahlongstring user: blank Pass: blank Request body: I have tried setting json and tried using the built in parameters Alert: Source Entity Name Alert: Alert Name Alert: Creation Time Alert: Severity   request headers: blank or Content-Type: application/json     so am i just missing something about the syntax? Or is the rest api call for nutanix api’s only?    Thanks in advance.

AOS 5.20 delivers performance enhancements that build on the breakthroughs in AOS 5.19 and expands on built-in key management capabilities for keeping data encrypted and secure. AOS 5.20 also increases the portability of VMs running on the built-in hypervisor AHV, streamlines advanced management capabilities, and more. A complete list can be found in the Release Notes. Nutanix Insights:Available with all new AOS releases is

I just updated a cluster’s AOS and am now getting the warning:AHV version 20190916.360 is currently installed on host, while minimum compatible AHV version is 20190916.410But I cannot AHV without updating also AOS to 5.19.2 which would change my plan to STS (currently installed 5.15.5.1 LTS)So I have to ignore the warning and waiting for a compatible AOS LTS version, or should I change to 5.19.2 STS?

Which node type does not deploy a Nutanix Controller VM. A bit confused with documentations available some say “Compute only” and other say “All Flash”One more question A vDisk is read by multiple VMs. The cluster creates immutable copies of the vDisk. What are these vDisk copies called.

We noticed that recently in our test cluster all operations take very long to complete. This seems to be due to long lasting “cerberus” tasks being executed with a type “uncharge”. Does anyone know what “cerberus” is doing or how I could speed it up? Whenever we kill the cerberus tasks manually all other queued ‘non cerberus’ tasks start to execute.

HCI runs on ESXi hosts, and VMs are protected with Async Protection Domain. I wonder, how to find which host a recovered VM will be registered with? I guess, it’s a certain service “leader”? Also, can I change it?

Not sure why but there appears to be an absence of documentation pertaining to required ports that might need to be opened in a firewall to access the CVMs. Perhaps Nutanix thinks that organizations aren't going to firewall off the cluster to protect access from malicious users. If I'm wrong why don't I see a list of ports that are needed to access the CVMs rather than KB articles showing what outgoing ports are needed in a perimeter firewall? In order to properly protect a cluster the CVMs should sit behind a firewall, which in my architecture this will be the case before we go live with anything. In order for admins to access the CVMs through a firewall TCP 22 is needed for SSH, and 80 and 9440 are needed for accessing the web console. Is this is? or are there more ports that would need to be opened up for the various types of admin interactions? how about running cli tools against the cluster? how about

I was trying to get AlienVault (OSSIM) to run on Nutanix, but I have hit a road block. I was able to get the install dialog to run after setting the boot to legacy bios. However, after install, It fails to boot.My questions, do any of you use any open source SIMS solution that works in Nutanix?I could accept a SIMS solution at a cost. However, after going through sales with LogRythim and splunk, I was frustrated because both of them incure log ingestion fees. We may have a good budget, but we are limited with our operational cost.Thanks for any assistance you can provide.

I would like to run a command from a host to gather the info just allssh does on cvms. I would like to avoid login into all the host and run a quick check from any of them. is there any easy way to do that?I read about hostssh command but my bash is not able to found it.
