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 ? [img]https://d1qy7qyune0vt1.cloudfront.net/nutanix-us/attachment/1561iBAB9B8FBC3F8C6C2.png[/img] 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.

Xpress Configuration Scenario

Hi, I apologize in advance for the long post !!!! From the information I've reviewed, the Xpress Models (I'm looking at Lenovo's offering) will support a maximum of 4 nodes. In addition there is no Protection Domain. Let's pretend that I'm a cloud provider for multiple customers, and I host their (Domain/File/Print/Email/Sql) servers in my 4 node domain. I want to use an (Acronis/Storagecraft) in VM backup software. These products store their backup images to a NAS/Share. If I setup a second 3 node Xpress Model that is storage "heavy" running Acropolis File Services, as a NAS/Share destination for my backup images, is there any restriction that you can think of that would prevent/limit me from doing this ? Right now we use StorageCraft and save to a Windows Storage NAS that has RAID 10 and I'm concerned that writing to will not be able to handle the I/O? I'm guessing that the 3 node Xpress AFS will easily handle intensive I/O writes. On weekends, the Full backup runs a

Palo Alto Firewall VM on AHV- PANOS 7.1.3 Bug on Upgrade

All, For those using Palo Alto VMs and AHV please be aware that there is a major bug when upgrading to PANOS 7.1.3 that will corrupt the firewall interfaces randomly and so far there is no fix for it, not even downgrading back to previous versions, in my case was PANOS 7.0.5h2. I am currently working with Palo Alto engineering into fixing the issue, I will update once the case is resolved. For the time being I would highly recommend to stay away from the 7.1 series of upgrades. Regads Juan

DIMM number and slot installation order

Hi folks, Do you guys have ever think about the question. I read some guides and confused now. 1) node memory number: It seems every type of node has different supported memory number configuration: For NX-1064-G4, It shows only support 16x dimm ! What happens if I install any number， i.g 1, 2, 3,4,5,6 or any number [img]https://d1qy7qyune0vt1.cloudfront.net/nutanix-us/attachment/1450i89B4BCCDB3F2197B.png[/img] 2) node memory installed slot location: It also says there`s an fixed slot order for different number dimm scenario. what happens if I install dimm not according to the guide ?

I've seen various examples online of using ISCI, SMB etc file shares but I'm not entirely sure on what to do. I've got the cluster as far as the file share witness working but how do I then configure the disks that make up the cluster resources? I will eventually be clustering SQL 2012 on this.

Occasional "Address Unreachable" errors with offline Foundation

I occasionally get errors on network validation when using the offline Foundation installer. Usually this is resolved by trying another range- occasinally not. I never have this issue when using the standalone version of Foundation. I am using a completely flat switch (which has had many successful installs), additionally this is with Foundation 3.2.2 and Java 7.45. I can log into the hosts/cvms and get successful pings from all of the IP's I'm intending on using but offline Foundation is adamant that some are unreachable. I solve this by using standalone (which can be a little cumbersome on the road). Just wondering if anyone else is experiencing this as well.

Strange Foundation process

Hi everyone, I imaged a nutanix cluster these days, and found strange phenomena. I found many error key words in foundation node log, but imaging showed successful finally. I clicked "retry imaging failed nodes with last config" many times, after some node failed, and it succeed. I`d like to know why it failed and succeed after just retry. also the foundation process tab showed 3 node failed at 78%, and the node log showed it`s finished ! and after retry, it`s 100%. I`m very worried about if it`s truly successful and there`s potential risks. p.s my environment: Foundation 3.1.1, AOS 4.6.1, ESXI5.5U3D，NX-1065-G4 [img]https://d1qy7qyune0vt1.cloudfront.net/nutanix-us/attachment/1437iFB4C37F4160B7ACC.png[/img] [img]https://d1qy7qyune0vt1.cloudfront.net/nutanix-us/attachment/1439iD2B0077C9E4C1B09.png[/img] [img]https://d1qy7qyune0vt1.cloudfront.net/nutanix-us/attachment/1441i15C9718ECFC6FC6C.png[/img][img]https://d1qy7qyune0vt1.cloudfront.net/nutanix-us/attachment/1443i821C11FF15

can I Separate cvm mgmt and esxi mgmt

Hello Folks, NX-1065 has only two 10G port, and two 1G port. and I have only one pair of 10G switch, and one pair of 1G switch. In my opinion, I`d like to make ESXI port(mgmt, vmotion,nfs vmkernel), and CVM port(prism mgmt, cluster mirror ) run on 10G switch, and configure 10g switch uplink to other network which I can connect to ESXI MGMT and prism. make vm data port connect to separate 1g vswitch. but network guy told me the 10g switch can`t uplink to externel network, so I`d like to know Can I move the ESXI port (mgmt) and CVM mgmt(VIP) to 1G vswtich， and create addtional vmotion,nfs kernel port connected to 10G vswtich, also leave CVM cluster mirror interface connected to 10G vswtich. networking design is the key things.

CVM cluster and ESXI mgmt&production network consideration

Hi guys， two basic questions: 1)can cvm cluster and ESXI data use the same 10g switch with no performance penelty ? (I have only one pair of 10g switch, and NX1065 one dual port card. As we know, cvm cluster must use 10g network, but I`d like also to use 10g for ESXI data network. ) 2) generally ESXI mgmt(usually,vmkernel port for NFS access) is on the same 10g link with cvm cluster(also CVM prism mgmt), If the user`d like to have a separate uplink or subnet for ESXI MGMT, is it ok ? I`m worried about the performance problem. thanks in advance !
