CVM Network

Dear Sirs Please advise , we are installing Dell XC 6320, where all network card are 10G (4x10G) and we used 2x10g for all the traffic (which is our test and development cluster) , we have total 8 nodes in the cluster. Someone is now telling us that the best practice is to use another 10G netowkr card for CVM traffic , as the CVM traffic in Nutanix is very heavy,which should not mix with production network card, Is that true , i have gone thru the previous posts and sure that 2x10G is fine for all Nutanix traffic, for my knoledge is the Nutanix CVM traffice is that heavy between nodes ? your reply is much appreciated.

Installing NFS VAAI VIB with VUM?

Right now we about to push ESXi 5.5 u3b so we can move on up to AOS 4.7.3.2. Since Nutanix doesn't support pushing out patches, we planned to do that with VUM which is fine. At least saving time from having to bring down each node manually for upgrading to u3b. On top of patching, we're also installing NFS VAAI VIB. In our lab, we do it via command line, but has anyone found a zip, or package that VUM can support pushing out that way we can just package our baseline with updates and the VIB file? We can't find anywhere that has a zip file or anything we can leverage thus far. Since we have two data centers a good number of nodes in the cluster at each, We'd love to save time if at all possible, so any advice is greatly appreciated. Thanks!

Which 10G SFP+ LR are supported for use with 8035-G5 and 6035C-G5 ndoes?

Hi, which 10G SFP+ LR (single mode) modules are supported in Nutanix NX-8035-G5 and NX-6035C-G5 nodes with C-NIC-10G-2-SI 10G network interface cards? Do the SFP+ need special branding, as e.g. for use with Cisco switches? Thanks, Erik

ESXi install

Where do you put the ESXi ISO files so they show up in Foundation hypervisor list? Also, is this considered a bare metal install? Also, if using Foundation, where is a good guide for installing using ESXi as the Hypervisor (Field guide not much help). Thanks

Lenovo HX failed to convert and use foundation to setup

I have 3 nodes of Lenovo HX and running on ESXi. As we need to use Acropolis, we decided to do one click conversion and the process failed by first node unable to boot up with anything and boot up with phoenix# boot. Decided to do a reimage of the cluster so use foundation 3.5 with AHV and 2 nodes manage to install but the same failed node failed to install and stuck at 17%. Upgraded firmware and tried manual installation using AHV and later ESXi together with phoenix disc and the same node still failed while running phoenix. Attached the screenshot of the error. Appreciate any help. Thanks.

Schedule auto-reboot of hyper-v host

Hello guys, I have a question regarding schedule auto-reboot of nutanix hyper-v nodes. Understand there is a cau preupdate powershell script to auto reboot the node 1 by 1 and ensure CVM is up and running before executing reboot action on the next node. Is there a similar script we can use so that we can schedule auto reboot the Hyper-V nodes 1 by 1 without having the risk of all the nodes / CVM or cluster down at the same time? Thanks. Regards, Tze Siong

Change vmk for cvm

Hi, We have a currently running nutanix cluster on dells and are looking to move the cvms to a new subnet. The new subnet has esxi management for each host, but on a different vmk, is it possible to point the cvms to the new vmk to get around the 'CVM subnet is currently different than the Hypervisor subnet.' issue? Cheers Thomas

Import Nutanix Clusters into SCVMM

Hi, I am new to Nutanix so would appreciate a bit of advice on importing a cluster into System Center Virtual Machine Manager. I have an existing Nutanix Hyper-V cluster which I want to manage via SCVMM. Has anyone got any advice in importing this into SCVMM and anything I should be aware of? Also, has anyone converted Standard switches to logical switches once the cluster has been imported or is that not a good idea? Thanks!

Medusa Down - Found Cassandra data files with future modify time

I have this same error on 3 nodes - I have checked networking / Time and connectivity and it all seems ok. Running ncc health checks on different services gives me a range of things to check. Not sure where to start with this. The Hosts are Hyper-V.

Nutanix, Hyper-V, Veeam and FC tape library

Hello Guys, I got a new environment to take care of and need some help here. Setup is based on Nutanix 3 Nodes with Hyper-V cluster. There is requirement to use Veeam BR as backup solution. All veeam components has to be virtualized i.e., Backup server, Proxy Server, Repository and Tape Server if required. Backup destination is a Tape library which can be connected via FC. Documents that I read "veeam on Nutanix with Hyper-V" mentions about hybrid scenario, where Physical repository server can be used to connect tape library. In my case there is no physical server available. What can be possible ways to get this done? 1. Is it mandatory to use a physical server to connect to tape? 2. Can an HBA installed in NTNX Node be used by a VM on Hyper-V (pass-through)? 3. Can I designate Hyper-V parent OS as Veeam Proxy and Tape server and use HBA directly from parent-OS? How about the compatibility/support in these configuration? If you guys have any other way to get this running, pleas

Timezone Configuration via UI

I know it's trivial via the ncli but I had to look it up. Timezone configuration via the Prism UI would make sense...

New Nutanix Block AHV

Hi All, We are about to secure our first Nutanix Deal (in our region) - our existing customer have a vsphere environment with 35 Virtual Machines (Exchange / AD / SQL / Oracle DB) - they are willing to go AHV. After setting up the first block - what would be the best way to migrate all virtual machines from existing vspehre cluster? Existing vSphere cluster is using VMFS data stores off their existing SAN. will be grateful for your suggestions / insights / best approach towards this. Kind regards

Daylight Savings - The RIGHT way

Hi all - we have HUGE problems in Denmark with setting the correct Daylight savings in AHV A clock / time settings apprently not just an option in AHV.. We found that we neede to set this in Windows guests to get the clock correct - otherwise it was 2 hours wrong reg add "HKEY_LOCAL_MACHINESystemCurrentControlSetControlTimeZoneInformation" /v RealTimeIsUniversal /d 1 /t REG_DWORD /f Now when we have shifted to winter time CET instead of CEST and we shutdown the VM's the clock is 1 hour wrong!! What is the 100% correct way to handle time on AHV? I have never had issues on VMware, HyperV or Xen with this basic stuff.. 😞 If anyone could lead me to a KB or something about this issue?
