Automatically Email NCC Results

Trying to setup a Nutanix cluster (non prod) to automatically email me the NCC results. Have setup the SMTP and alert email configuration sections in Prism Element. Verified from a CVM that emails are being sent okay. Next, on a CVM, I ran ncc --set_email_frequency=4 and saw that it took successfully. Finally, running ncc --show_email_config but gettting result Value for the flag --show_email_config has not been set. Obviously I am missing something?

CVM with several network adapters

Hello, We would like to validate some design aspects. Our environment is based on DELL XC630 & XC730, Nutanix 4.6.4 ( in the future 4.7) and EXi 6.0 u2. As for administration perspective, we need to affect an administration subnet IP to the IPMI interface. The CVM needs to be in a production subnet. There is no routing from production to administration subnet. Is it possible to deploy 2 network cards on the CVM for the CVM to communicate with IPMI interfaces ? Is that a validated and supported design by Nutanix. Thanks in advance for your answers.

Question on Local disk vs NFS Datastore

A rather simple question :) Once the NFS Datastore has been presented to the nodes, each node shows the NFS Datastore and the Local disk as available storage. My question is, how do others deal with this scenario? What is to stop an admin from storing data to the local data store as opposed to the NFS data store which is where you want them to store their VM's? Curious how others have dealt with this. Thanks, Sky

One-Click NOS Upgrade

Hello - Trying to upgrade via one-click upgrade in Prism from 4.0.2.2 to 4.0.3. Even though I have "Enable Automatic Download" enabled it does not show 4.0.3 as "available compatible version." However, I have another identical cluster which shows 4.0.3 as available. Anything I am missing to make sure Prism auto downloads the latest NOS from Nutanix? Thanks.

Maximum SSD to HDD Ratio

just wondering the following:Everywhere you look it shows nutanix configuration of 2 or 4 SSD with the rest being HDD. With the advance of having all flash nodes on every model, is there anything stopping us having lets's say 6 SSD and 4 HDD? Or 5 of each in a node supporting 10 Disks?Does the Pro License also enable us to pin VM or part of it to SSD?

Migration from "Legacy" ESX to Nutanix ESX

Hello's I have an existing VMware install using a storage array. I have a three node Nutanix cluster that i'll be migrating to. I've read through some of the solutions offered and i have an additional question. When i migrate my VM's using vmotion from the legacy platform, do i have to make a decision to which host on the Nutanix side the VM will reside and if so, do i have to think about balancing out my VM's across the three hosts? Thanks all for your time, Sky.

start httpd on cvm

after launching the foundation applet I could only see two nodes instead of three, i logged into the cvm on which i configured my IP address. On restart, the httpd service failed. I presume this is why the applet could not add that node. please any suggestions as I am onsite

changing cluster RF from RF2 to RF3

Hi, we have installed a 4 node Nutanix cluster. In the installation process you have to select the cluster redundancy factor, RF2 or RF3. We tried to select RF3 but the system says that you need at least 5 nodes. So we were forced to create the cluster with RF2. In the future we plan to extend the cluster with additional nodes, may be only storage nodes. Will it be possible to upgrade from RF2 to RF3 without having to delete the existing cluster and create a new one? Stefano

questions about new AHV installation

Hi Folks, I`m installing a new also my first AHV(latest version installer-el6.nutanix.20160601.20,with latest AOS4.7.1). I`m new to KVM,as well as AHV. So some problems met, tough time these days. Any help would be highly appreciated, thanks in advance. 4) centos 4.7 guest vm also the guide 《AMF_Guide-AOS_v4_7》 says only support CentOS 6.4, 6.5, 6.6, 7.0, 7.1, 7.2 Is there a support matrix for all the vm guest type ? 7) kvm vm mgmt via Prism there`s too little function for manaing ahv hypervisor and guest vm via prism(it seems only basic vm life-cycle mgmt). Can I add usb device, make an ovf template like vmware vcenter ? I`m not such familiar with virsh, ovs cli tool

Migrate from vSphere 5.0 to Nutanix running vSphere 6

How would I migrate VM's from an existing vSphere 5 cluster to a new Nutanix Block running vSphere 6? Would this work: Add the existing vSphere 5.0 hosts to the new Nutanix vCenter as a seperate Cluster Ensure the vMotion network on Nutanix is the same as the existing hosts and thet can talk Upgrade the existing vSphere 5.0 hosts to 5.1 vMotion using the web client to Nutanix Hosts and Nutanix storage Or is there another method?

Mixing paid and CE editions

Hey all! Just got my 3 node monster Nutanix box up and running and LOVE it! Quick theoretical question though: I blew through my budget on this box, and would LOVE to have a DR setup somewhere else in the building (to combat fire, flood, earthquake, etc.) Could I take some spare hardware lying around, and as long as it meets the specs needed, install the CE version, and make that the DR for my existing paid for version of Nutanix? I've gotten mixed answers from various people is why I ask. Thanks in advance!

Which Phoenix version to use?

I am a bit confused. On the Nutanix support portal, in the Downloads section for Phoenix, it say's, "Phoenix is a tool used to install the Nutanix Controller VM and provision a hypervisor on a new or replacement node in the field. You can download a Phoenix ISO file from this page. Each Phoenix ISO file is for a specific hypervisor and Acropolis base software (NOS) release." But then when filtering, it shows Phoenix versions 2.1.1.1 to 3.0.4 are for Hypervisor "All". And then Phoenix version 2.0.4 has seperate downloads specificlly for KVM, HyperV, or ESXi, depending on which Hypervisor your are deploying. Which Phoenix download are you supposed to use if wanting to deploy an ESXi 5.x or 6.x Hypervisor on the nodes in the field?

Nodes reset/reboot events

We have had two instances where a node detected/reported a fault event and reset rebooting vm on each occasion. There seems no reason for this to have happened. Details Host 192.168.xx.x4 appears to have failed. High Availability is restarting VMs on hosts throughout the cluster. 08-17-16, 02:01:41am Host 192.168.xx.x4 appears to have failed. High Availability is restarting VMs on hosts throughout the cluster.08-11-16, 07:19:48am We updated the AHV and NCC and since had a repeat last night from the first instance last week Is there a potential hw fault with the host that has not yet been detected or checked?

Erasure coding - 4.7 - Where did the option go?

Hey, We're in the process of getting an exchange server virtualized and according to Nutanix best practice, we should create a container with EC-X enabled. When I go to create the container in the PRISM gui, there's no option to enable erasure coding. This contradicts documentation where it shows the option under "advanced options" but on my end, it's not appearing.

NCC disk error after disk move

We had an issue when the cluster was first setup which involved the hdd. These were moved and replaced and now we see an error reported. It was initially cleared and now resurfaced, this despite a AHV update from 4.6.2 to 4.6.3 and also update on NCC to 2.6.6 Error Detailed information for disk_online_check:Node 192.168.xx.x4:FAIL: Disk '/home/nutanix/data/stargate-storage/disks/S460AATC' failed on node with ip u'192.168.xx.x3'.
