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

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

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

Getting UUID's to pass to Ansible

Hi all, I’m very new to Nutanix, and pretty new to Ansible. I’ve been tasked with updating / installing guest tools on any machines that need them, and they’d prefer to do it via Ansible. I’d like to be able to have Ansible use the uri module to grab the UUID of a given VM, or grab a list of UUID’s and the associated VM; however I’m having a lot of trouble parsing this information out in a way that Ansible can actually use it. Does anyone have experience with this? Or at least can tell me that there’s a better way to be doing this? Thanks!

W2k19 Image and cloning it for sysprep - patch monthly

I have a W2k19 VM I created as a patched image. Idea is to patch it monthly. Shut it down and clone it. Then sysprep the clone and copy the disk to the Image Service. Then I can create VM’s off of it. I will repeat the colne after patching the ~master image monthly in order to keep a patched disk ready to spin up VM’s from. We are using AHV, version 5.10. Mt question is the “CLONE” a full, independant copy of the VM ? TIA -S

Why the 'Guest OS' field in nutanix vm is NULL?

When I pull the VM details using powershell, the Guest OS for all of my VM is empty. I am using the correct syntax '$vm.guestOperatingSystem' to pull the information. All the other information like VMName, Container, PowerState, NetworkAdapters, etc... are coming except Guest OS and Description of VM. Even if I create a new Windows Server 2012 R2 VM, the Guest OS field shows nothing for new VM as well. I have 47 VMs currently on a Nutanix host but the Guest OS information is empty for all of them. Please let me know if anyone else is having this issue and how to resolve it. Details: ---------------------- Hypervisor: AHV

Nutanix lcm screen does not come out and loading continues

Hello,I am conducting a test using NX-3050 equipmentI know it's an old Node-Model and I have previously installed it with AOS 5.20.2.1As you can see now, we are going to test the upgrade using LCM in AOS 5.10.11.1LCM was installed as shown using 2.5.0.2.32663 Dark-site​​​​​I uploaded the file 5.20.2.1 because I saw the opinion that if the AOS version for upgrade is EOS,it might not be displayed on the screenNo matter how long I wait for the LCM in the setting window, there is no screen, so should I reinstall it? I think I saw the opinion that the AOS version was modified because it was low, so is it impossible to update using the LCM DARK site? Thank you for reading the long article and I would really appreciate your opinion

Expand VM Disk Size for Linux REST API, acli or ncli

It’s totally available in Prism UI. But I find it impossible with API:In REST API, using PUT /virtual_disks/ “disk_capacity_in_bytes” receives 200 but not size changes. In ncli, using vdisk edit name=<> max-capacity=<> runs, yet the same no changes. Since the VM disk of this Linux VM doesn’t belong to any volume group, not an option for acli the way I see it.And if I do it via VM commands, it’s only able to create new disk or clone disk, not expand which is what I want.I really need an API for this job. Any ideas? Thanks!

How to Grant Prism Administrators Access to CVMs through SSH ?

Currently we are working on a project that requires couple of Admins to SSH into a CVM to execute some commands.  The problem we are running into is that only the Nutanix\Admin default account can actually SSH  into CVMs. Other non-default admin accounts (Cluster Admin) can do everything in Prism but are denied access when they try to SSH. Do The non-default admins need additional permissions\configurations to be able to SSH into CVMs ?

REST API to Convert IDE Disks to SCSI

Hi Folks,   I have a few machines I would like to convert from IDE to SCSI.   I understand this can be done with acli. The procedure is to clone the ide disk and replace it for the VM.   nutanix@cvm$ acli vm.disk_create <vm_name> clone_from_vmdisk=<vmdisk_UUID> bus=scsi   However, I’d like to do this in PowerShell given I’ve already started developing down that track. I have PowerShell cmdlets to snapshot and shutdown the VM which are recommended steps before performing this task.   I didn’t see a cmdlet to perform the clone and replacement, so I turned to the REST API. I am fairly new to Nutanix to I wanted to get some feedback on whether this is the right approach or at least that its not going to break anything other than my test VM. $uri = "https://$ntxCluster/api/nutanix/v2.0/vms/$($vm.vmid)/disks/attach"$body = '{"uuid":"abcdefg-08h3-4i44-95j0-kl44m82no758","vm_disks":[{"vm_disk_clone":{"disk_address":{"device_bus":"SCSI","device_index":123}}}]}'$headers=@{}$headers.A
