cluster in China stuck downloading NOS upgrade

I have a cluster in China running 4.5.x Because I upgraded my prism central to 4.6.x and didn't realize the older 4.5 was not supported I have to upgrade the cluster too. the unit in Mexico was able to download and install from the GUI. The download in China seem to get stuck, so I clicked the cancel download button. now I'm trying to upload the latest 4.5 code from a machine in china through the GUI. But it just errors out. The alerts say the download is still running. Not sure how to move forward from this point. Thanks,jb

Streched Cluster with Hyper V

Hello, is it posible to create a streched Cluster with Hyper-V? Is there a site awareness, so one side of the Cluster can go down? Or a workaround? Ideas? Best Wishes Johannes

container_mount_check fail

Hello Guys, I need your help because I run into a strange issue with my Nutanix cluster (NOS 4.6). Nutanix generates a warning as below: "Data Protection > Protection Domain > Container Mount > Containers are not mounted on all nodes". We've got only one container and it's properly mounted on all ESXi 6.0 hosts. NCC (ncc health_checks data_protection_checks protection_domain_checks container_mount_check) returns: Detailed information for container_mount_check:Node [url=http://172.30.10.13/]172.30.10.13[/url]:FAIL:Container ntnx-ds not mounted in : 172.30.10.111 172.30.10.112Node [url=http://172.30.10.12/]172.30.10.12[/url]:FAIL:Container ntnx-ds not mounted in : 172.30.10.111 172.30.10.113Node [url=http://172.30.10.11/]172.30.10.11[/url]:FAIL:Container ntnx-ds not mounted in : 172.30.10.112 172.30.10.113Refer to KB 1888 for details on container_mount_check I've checked all tips from KB article 1888 but everything seems to be OK.

What's the behavior when the Nutanix node local storage is not enough for data of local VM?

Hi All, According to my material on hand that Nutanix will keep a copy in local storage for local data required. So if there are some storage intensive VMs running in one node and the local storage in that node is not enough for data of all local VM, some data should still need to be retrieved in remote node? would like to know the exact behavior. And one more question for DR. If I use vsphere, I still need to buy SRM license or SRM is optional (e.g. for some dedicated features?). For Hyper-V, since the DR feature of Hyper-V is not as rich as VM, can we still use the "Protect Domain" feature in Nutanix for DR in Hyper-V? Thanks a lot in advance! Best Regards, Teru Lei

Lost a CVM while updating ESXi

I went about updating a couple ESXi hosts the old school way with using zip files and doing vib installs. My first host worked without a hitch. My second victim... I mean host is having problems. In total I installed 4 zips per host. After bringing the second one back out of maintenence mode, and having the CVM start, a few minutes later I keep getting errors about the CVM not connecting. Then I check the console on the CVM in question, and it keeps rebooting, after a kernel panic. Here's the beginning of the output: [img]https://d1qy7qyune0vt1.cloudfront.net/nutanix-us/attachment/971iE6A6E0FF19ABCDA1.png[/img] Any insight on what I can do?

Set-NTNXcluster showed unexpected behaviour

Hi Folks, Got something wiered happened today, might be a bug or something. I was to change current time zone setting by Get-NTNXCluster | Set-NTNXCluster -Timezone "Australia/Sydney" However it throw me an error: "The cluster name may contain only English letters, decimal digits (0-9), dots, hyphens and underscores. Set-NTNXCluster : The remote server returned an error: (500) Internal Server Error." Then I thought it might be because I did not include cluster id, so I ran below command : Get-NTNXContainer -Id xxxxxxx-xxxxxxx-xxxxxx-xxxxxx-xxxxxxxxxxxxxx::4769 | Set-NTNXCluster -Timezone "Australia/Sydney" Apprently you will find instead of using Get-NTNXCluster, I used Get-NTNXContainer which I copied from command I previously ran without double check, you would assume that will throw me an error, but it did not, it finished with a "Success". Yes, it did change the timezone on the cluster, however at the same time it changed cluster name to the Container name as wel

Network Considerations

Hi Folks, I'm in the middle of a deployment and have a question. We have a pair of Nexus 3548's acting as 10 G edge switch to our Nuntanix Clusters who are trunked up to a pair of Cisco 4500's We have 4 nodes in the cluster with a total of 10 nics all 10 gig and assigned to the VDS in Vsphere. On the VDS we set the MTU to 9000 Is there a way to separate the CVM traffic from the management traffic? I would like to keep the CVM traffic from going up to the 4500's however we needed to create an SVI on the 4500's so we could manage them. I'm getting Jumbo frame errors on both the Nexus and the 4500's and when I set the MTU on the VDS back to 1500 the errors went away. My guess is the CVM traffic is what's causing the issues and I would prefre not to mess with the MTU settings on the 4500's. What is best practice here? What are other doing? Thanks

Nutanix Template for Zabbix

Hi all! I'm currently working on a Nutanix Template for Zabbix that I will share with community once it's finished. I've a little problem with some SNMP answers Zabbix receives from prism. I'm asking for OID 1.3.6.1.4.1.41263.11.1.3.1 This OID is the cstControllerVMStatus.1. It should return Up or Down if the CVM with index 1 is Up or Down. When I run it in Zabbix, the answer is "55 70 00". Is "55 70 00" a value that means 'Up'? In this case what is the value for 'Down'? Regards,

How Foundation works?

Hello Nutanix community, Yesterday, I tried installing a Nutanix block by Foundation PC to change the hypervisor from HyperV to AHV. But unluckily error occurred with 3 nodes per 4 nodes and one node had been successfully installed. Although all 4 nodes had already run with the same configuration before, why this case happened?! After 1 day troubleshooting, I had finally and luckily installed 3 nodes left by resetting IPMI on these nodes. As I already followed the Foundation document from Nutanix, "please have a look at the logs files at /data/logs/foundation... on each nodes" to get the details of problem, but actually, in my case those log files did not contain any data that related to the errors occurred?! So how could I dive deeper into the problem that I had? They were still there but no words, to sentences, no data?! I really need a document that explains in detail how Foundation works, so that I can troubleshoot it easier than I had yesterday. Can Nutanix publicily post it

While using Foundation i have selected to install ESXi 6.0 and the NOS version is 4.5.2 For a weird reason (im new at nutanix) three of them (6035-C) where intalled with AHV and three of them with ESXi 6.0 (6035-G4). Is this an expected behaviour? Regards. Francisco.-

New installation vsphere 6.0U1a CBT issue

Hi all, finally, after a long POC i'm a new Nutanix customer :D I'm waiting N°2 NX-1365S with 6 nodes and the idea is to create a new vsphere cluster version 6 and migrate the existing VM's from the old vsphere 5.5u2. I've just check the Nutanix support page and i see the latest supported version is 6.0u1a build 3.073.146. This version seems to be affected to CBT issue, is it possible to install the correction patch ([url=http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2136854)]http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2136854)[/url] after the the installation? Or install directly the 6.0u1b? Thanks in advance, and have a good w.end!

Can configure the SSD capacity as an extended memory area in case physical memory is constraint?

Hi All We have a customer whose workload is currently fully virtualized on VMware integrated over a Legacy Three Tier Architecture. Most of their hardware devices is EoL, and after an audit of the infrastructure, we have recommended them to go in the direction of Hyper Converged Infrastructure, focussing on Nutanix They are potentially looking at a configuration of 1TB minimum per node of memory. Is there a work around to configure my SSD as an extended memory area to able to match their requirement? Kind Regards
