CVM Crashed

All, I have a 6 Node 1065 system in 2 blocks.  Recently one of the CVMs (node 2, block A) crashed.  When rebooted it was just going in loops.  When diagnosed it seems the SSD (not the SATADOM) had failed and we replaced it.  When we try to boot the CVM, it still just loops. We were told to boot that node with Phoenix which the cluster provided me for download.  I do that and it doesn’t load Phoenix and gets errors instead.  I’m looking for a suggestion of how to get the node back to 100%.  At this point (and throughout) the ESXi on the SATADOM has booted fine and I guess if I didn’t care about the storage side I could just ignore this but I’d like the system to be fully healthy. Any suggestion about how to get the CVM working again would be appreciated. Thank you Johan

Protection Domain Based DR

Hi, I am having two physical sites with on-prem nutanix cluster. I am trying to config async dr from primary to secondary site every one hour. So the snapshot will trigger every one hour and replicate to the secondary site. I read in the portal , the first replica is a full copy and the subsequent are incremental. My question here is , once my first replica, which is a full copy of my data was completed to the secondary site and certain period of time, my first replica will expire and deleted based on my retention configuration. In that case, how can I restore my full data with the help of incremental snapshot from the remote site?

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?

Acropolis File Services Setup error and confusion

Hello Nutanix I am currently in progress of deployment of Acropolis File Services (AFS) Everything has been going well until the "Can't contact LDAP Server" error occured I have given it a check by viewing some configuration on NVM and found out that although on Prism, they have been assigned with 2 IPs but actually running with only 1 IP when checked via console by ifconfig command (eth0 only) Let me make it clearer via the "topology" below: CVMs connecting to NVMs by Subnet A IPs Clients, AD and DNS servers should be connected to NVMs by Subnet B IPs Recently, those NVMs are running with only 1 Subnet A IP although on Prism, I saw they have already assign with both Subnets?! My block is running with AOS 4.7.2. I have also given some seaches around and seen that both Internal and External networks could be the same as described in this video?! [url=https://www.youtube.com/watch?v=Q-z11wVhBxA]https://www.youtube.com/watch?v=Q-z11wVhBxA[/url] Thank you in advanced

PowerShell Cmdlets Update?

Are there ANY plans to expand on the PowerShell cmdlets at all, specifically for getting host info? They’re pretty bare bones. I don’t even know the last time the cmdlets were updated/expanded. It seems to me Nutanix regrets making them and hopes they will quietly die. I have relied heavily on PowerShell to keep tabs on a very large Nutanix environment running Nutanix on both AHV and ESXi. I’m talking 700+ nodes. The ESXi clusters are no problem getting the info from because I use VMware’s PowerCLI to supplement the lack of data I can get with Nutanix Cmdlets, but the AHV clusters are another story since I don’t have PowerCLI to fall back on. Can we at least get a cmdlet that will allow us to use PowerShell to initiate ncli or acli commands, like VMware does with the “Get-EsxCLI” cmdlet. That would be very helpful.

Nutanix API v2

Hi! I've got several questions about the usage of v2 API which I have not been able to solve by myself after looking a little while.on some endpoints, for example, GET /alerts, GET /vms and a few more things are functioning for me as expected, but on other endpoints, such as POST /vms/{uuid}/set_power_state I am receiving the following response:{ "message": "Access is denied", "detailed_message": null, "error_code": { "code": 1100, "help_url": "http://my.nutanix.com" }}any idea what's causing it? I've been searching for detailed information on your error code (such as 1100 listed above) and couldn’t find. Is there any documentation to the error codes that  you can send me a link to?Also, in a few of the API endpoints I couldn’t understand exactly what is the expected query parameter to be sent.2 examples of endpoints I felt I am lacking knowledge what exactly meant to be sentGET /vms filter: Filter criteria - semicolon for AND, comma for OR. where can I find what counts as fi

NIC Usage on Nutanix Servers

Hi, Im planning to add 2 more blocks NX-3060-G6 with 2 nodes on each block. Currently i have 2 Block Nutanix NX-3060-G6 with 2 Nodes on each block.Current topology is 2 Block nutanix connected to Cisco 2960X with all eth interfaces connected to it. My question is, In NX-3060-G6 there are 3 Ethernet interfaces, 1 for MGMT (IPMI) and there are other 2 eth interfaces and 2 SFP+. For networking purpose,Do we need to use those 2 eth interfaces from each node in order to work? Or do we need to use only 1 eth interface only on each node? We’re adding 1 more switch Juniper EX4600, so if we need to use those 2 eth interfaces, can we separate them? 1 Eth interface to Cisco 2960X and the other goes to EX4600? Can i have different VLAN on each interfaces (exclude MGMT) that i connect to switch?Sorry if my question isn’t clear enough. But i hope you do understand it. Thank you.NX-3060-G6Networking Topology (Just for Eth Interfaces)

Interpreting performance metrics

Hi everyone,I’m using the API to pull VM performance stats, however I’m having trouble interpreting what I’m seeing.For instance, I’m pulling “hypervisor.cpu_ready_time_ppm” for one of my VMs and getting the following output:{ "statsSpecificResponses": [ { "successful": true, "message": null, "startTimeInUsecs": 1576458000000000, "intervalInSecs": 30, "metric": "hypervisor.cpu_ready_time_ppm", "values": [ 108, 97, 144, 107, 89, 92, 78, 74, 47, 49, 90,.... Output truncated for brevityI get that the metric is a percentage but obviously you can’t have 144% of time, so how should I interpret these values?What I really need is a guide and/or reference that explains all of these metrics and how to interpret them.I found the following link but it doesn’t really tell me what I want to know:https://portal.nutanix.com/#/page/docs/details?targetId=Prism-Central-Guide-Prism-v51:mul-alerts-user-created-metrics-r.html

Prism Network view anomaly?

Hi All I have something odd in my Network view in Prism - I have 3 switches ( 1 switch is a 2 switch stack) but the view shows 5 switches, 2 classified as None. The None entries have the ip addresses of one of the single recognised switches and the stack which is already identified. The other odd thing is that the Nones have ports that I would expect to see in the identified switches. Can anyone tell me how to correct this?

AHV versions and compatibilty with AOS

You might have noticed that the versions of AHV hypervisor have names starting from the year, such as 2017 and 2019. For example, AHV-20170830.434 and AHV-20190916.231.  The difference between them is that the versions starting with 2017 are built on CentOS 6 image, while the ones starting with 2019 are based on CentOS 7.    It is very important to note that all the 2019 AHV versions are only compatible with AOS versions 5.16 and newer. It means that the current LTS AOS versions 5.10.x and 5.15.x do not support AHV 2019. The AHV 2019 is currently supported only with STS AOS versions.   The cluster will not let you upgrade the AHV to 2019 version if you are below 5.16. But it is possible to manually image the node with the AHV 2019 ISO and install the earlier AOS there. Also, it is possible to upload the non-default AHV during the foundation procedure together with earlier AOS. Such configurations are unsupported. If you have already done that, you will have to go to the STS AOS to
