Solved

Hi there,I need explaination about vCPU usage :My CPU Model is Intel(R) Xeon(R) Silver 4208 CPU @ 2.10GHz (8 core, 16 thread)  I have two socket per host So 2 x 8 = 16 cores and 4200 Mhz (base freq) / 6400 Mhz (max turbo freq) So 32 vCPU (16 cores x 2 = 32 thread with Hyperthreading) A VM use 6 vCPU and 1 core Prism report for this VM, 97% of CPU usage97% of what ? Is that 6400 / 32 x 6 = 1200 Mhz ?? The half a physical CPU ?How that calculation is made ?Thanks,Jerome

Hi all!In an attempt to solve a problem with “round-tripping” JSON I’ve concluded that the only fix is to use PowerShell 7 since the ConvertTo-Json cmdlet in version 7 allows me to escape the troublesome characters.This solution might just be me robbing Peter to pay Paul though as I now face the issue of getting Calm to use PowerShell 7 instead of the default 5.1 (a.k.a. Windows PowerShell).I’ve gone so far to set the default PowerShell remote endpoint (windows.powershell) to point to PSH 7, which works if I do a traditional Enter-PSSession but not if I execute a PowerShell script in a Calm runbook.Which leads up to the title of this topic, how does Calm execute PowerShell on an endpoint?Since it’s using port 5985 it should be WinRM/WSMAN/remote PowerShell, but it completely ignores the fact that the default PSH remote endpoint is pointing to PSH 7.Is it using another endpoint? Or is it not using WinRM after all?

Hi all!This might not be a Nutanix Calm specific problem, but since I’m experiencing the problem within Calm I’m posting a question here (as well). :)I'm grabbing a VM definition using GET https://${PCHostAddress}:9440/api/nutanix/v3/vms/$VMUUID. I convert the payload to an object using ConvertFrom-Json, manipulate it using .Remove() to remove the Status section (among other things), and convert it back to JSON with ConvertTo-Json.When I send the modified payload back using PUT https://${PCHostAddress}:9440/api/nutanix/v3/vms/$VMUUID, I get a "(400) Bad Request." Thinking I screwed something up when modifying the payload, I removed the part of the code that changes the object but still got the same error, even though I'm "just" converting the unmodified payload from and to JSON.Sending back the payload without converting from and to JSON results in a "(422) UNPROCESSABLE ENTITY”, as it should.In this case the -Depth parameter isn't the culprit as far as I can tell (I've added -Depth 10

Hi!I need help wrapping my head around how the while loop in Calm works. The documentation is unfortunately not helpful at all. :/The first thing I can’t understand is why a while loop has a fixed number of iterations. This to me is a for loop. A while loop runs while a condition isn’t met.The second thing that’s confusing is the exit condition that I can set to Success, Failure, or Don’t Care. I guess that Don’t Care turns the while loop into an actual for loop?The Success or Failure condition is as far as I can tell completely out of my hands as this is based on the result of the execution of the task(s) within the loop and not a parameter I control. Do I have to fail a task on purpose to keep the loop going if I choose Success as my exit condition?What happens if I have multiple tasks in the loop, do all tasks need to fail or succeed for the exit condition to trigger?Is it possible at all to set a parameter in one of my scripts and then use that as an exit condition?Thanks.

Hi, in the security advisory “nutanix-sa-023-log4j2” ifor PC is mentioned: Prism Central (All supported versions) Patched as part of 2021.9.0.3, release pendingWhat is the expected release date?

Hi!I want to use the Prism Central API to create and connect a vdsik to a VM. The only examples and topics I’ve seen for creating and attaching vdisks uses the Prism Element API, i.e. using a specific CVM as the endpoint.I don’t want to use a specific CVM as this is to be an orchestrated task triggered by our ITSM system. We can’t rely on a specific CVM to be available and would much rather use Prism Central.However, I can’t find any API calls that seem to be able to create and attach a vdisk. Maybe the PUT /vms/{uuid} call is capable of this but I can’t see any mention of this in the documentation.Is there a way to do this with Prism Central?

How do i change the name of an ESXI host and CVM in a Nutanix cluster?

I haven’t noticed any messages or communications regarding the recent log4j vulnerability (CVE-2021-44228). Does Nutanix have some formal announcement for customers on the status of this threat as it relates to their product portfolio? 

Hello, We have an old NX-1050 and I’m wondering what is the recommended AOS, Foundation, ESXi for this? I cannot find this model in the Compatibility Matrix website. Thanks!

I installed a new VM with Windows Server 2022 for testing and when I try to connect through RDP it works fine for 10 seconds and then I get a frozen screen and no response. Can you tell why is that?

Hi fellas,Does anyone have a clear answer of what is the real cost of AHV?  I’m told that AHV is free but is this referring to only Nutanix Community Edition? What about AOS? when purchasing a Nutanix node/block/cluster, these come pre-installed but the cluster essentially has no ‘smarts’ without the CVM which is AOS.Referencing this Licensing Quick Reference Guide, it looks like AHV is included with AOS but AOS’ licensing metric is charged per node.  Am I reading this correctly?Is it possible to run AHV without AOS? Thanks,JS

The Nutanix AOS/AHV was installed on the DX equipment, and the ISCSI Data Services IP was also set up. The Volume Group tab and create Volume Group  are not visible in the Prism - Storage - Table.AOS version is 5.20.xIs Volume Group not supported for DX equipment? Or do I need another setting after AOS 5.20?

Hi.I’ve verified with this post and this post that I’m sending the parameters correctly and that the variables in my runbook are set to Runtime. I’m also doing a POST call but I still get an internal server error with the message "'NoneType' object has no attribute 'get'".Here’s the body of my call:{    "spec": {          "args": [            {              "name": "email",              "value": "mema@tlke.se"            },            {              "name": "displayName",              "value": "Mom MEmem"            },            {              "name": "userName",              "value": "momemom"            },            {              "name": "accountName",              "value": "MAM, MSM 1"            },            {                "name": "ticketID",                "value": "794"            }          ]        }      }    }  }The runbook has multiple tasks, does that change how I send arguments to it?Thanks.

Hi Team,Does anyone know when AOS 6 LTS version will available? On Prism or support portal.

I just finished both NCP MCA and ECA and got a certificate, when I downloaded the voucher certificate there is no voucher code in it. It says that “your NCP-MCA vocher code is” but I’m not seeing any voucher code same for the voucher certificate for ECA. Need help on this.

How can i get practice questions for Nutanix Certified Associate exam

It seems that when updating AOS Nutanix is creating backups of /home/apache/www/ called PrismUI.tar.gz . Those are then stored in /home/apache/www/console/ . It further seems they tried (but failed) to exclude this console directory. (Don't have the exact tar command line any more but I guess Nutanix can find it) This means that later backups include all previous ones, recursively. I.e. backup #1 is OK. But backup #2 will include #1. Backup #3 will even include #1 and #2 (including another copy of #1). And so on. Which means the file size of subsequent backups grows FAST. For one Cluster the file grew from the usual ~125 MB to over 3GB. This in turn leads to the backup being rejected and recreated constantly. Probably bad for the SSDs.This happened on all Versions I was able to check: ESXi: 5.20.1.1, 5.20.2 AHV: 5.18.1.2 5.19.0.5 6.0.1 6.0.1.6 6.0.1.7 6.0.2Here the most egregious example:$ sudo find / /home/ -xdev -iname PrismUI.tar.gz | xargs -d'\n' ls -lah-rwxr-x---. 1 nutanix apache

I have the same question as in topic (https://next.nutanix.com/calm-application-management-55/passing-variables-to-calm-runbooks-39356)I have created a runbook, configured a variable  under the “Configuration” section of the runbook.I can launch the runbook via API, but it does not pass the value.I tried passing the below sample as the body of the request.What am I missing ?  { "spec": { "args": [ { "name": "VariableName", "value": "value" } ] }} 

Hi all.I’ve been searching all over the Internet, and the Nutanix documentation, to figure out how to pass variables from one task in a runbook to the next. I know that I need to print it to the console in the format “statusMessage = ‘This is the status message’” but so far I’ve tried with Write-Host, Write-Output, and Write without any luck.I’ve also tried using both @@{statusMessage}@@ and @@{Task1.statusMessage}@@ in the next step without any difference.How am I supposed to do this, and why isn’t it properly documented?Thanks.

I have successfully run Collector against our Prism Central which manages about 22 clusters.  It took a long time to run but after it was done, with no error messages, there was no data.  How can I start to troubleshoot this?  I did find this in the logs…. 2021-11-04 13:56:33,288  INFO:  connecting..2021-11-04 13:56:33,304  INFO:  Initializing data collection2021-11-04 13:56:33,304  INFO:  Collecting datacenter data2021-11-04 13:56:33,304  INFO:  Collecting vm data2021-11-04 13:56:41,018  INFO:  'NoneType' object is not subscriptable2021-11-04 14:05:19,187  INFO:  Invalid response while getting clusters2021-11-04 14:05:19,187  INFO:  "{\"Prism Central\":[\"0005a047-ec19-f45f-4962-ac1f6b3bd5cd\",\"00056880-2345-ae87-7622-ac1f6b61a91e\",\"000534cb-9366-4532-0000-00000000c24c\",\"0005883e-3aa8-a7ce-0000-000000028588\",\"0005b846-f7d2-6368-1cd9-3cecef19a428\",\"00058c64-2e36-5f32-0000-000000028204\",\"000538ca-9aa8-9183-2c4c-0cc47ac328b5\",\"0005b8ab-8d4e-03c1-59a3-3cecef19c0c6\",\"0005869

Hi!We have two Nutanix clusters running ESXi v6.7.0 with a Horizon 7 VDI environment on each.  We needed to be able to sync Horizon AppVolumes between the clusters via some common storage.The solution we were set up with was a FreeNAS VM on one cluster publishing an NFS share which was then attached to the hosts in both clusters.  We weren’t bothered about high availability as it’s not an issue if the replication of the appvolumes goes down sometimes as it’s only needed if appvolumes are being changed or their assignments to users is changing.After an NCC upgrade, Prism Element now flags up this external datastore as unsupported.  I’m struggling to find out from Support what the actual magnitude of risk is here to the stability of the clusters (especially when it comes to upgrading firmwares, AOS etc).Does anyone here have any thoughts on this situation please?Thanks for reading!

During VM creation  in nutanix ESXI, if we select the thin provisioning and submit the operation once , it shows thick provisioning if we see the disk settings. what will be the issue ?

Hi guys,I want to run some tests on a local system, so I created two VMs that are isolated from my production network.So, I created a network in the cluster just to be used by these two VMs. This network does not exist in production, only within the cluster.I added the NIC for this network on both VMs. But even so VMs do not communicate, I cannot ping or access via SSH from one VM to another.This type of configuration, just for testing, is not possible with AHV \ AOS?     

We have a UTM with 6 interfaces that go to separate subnets. Each subnet has a ToR Switch. The UTM handles the routing. We are installing a new Nutanix 4 node Block and virtualization physical servers. Assuming that we have 6 physical servers and each server is on a separate subnet, what would our network diagram look like if we included the Nutanix Block? Would we need another switch that has the 6 subnets vlanned, ie: 1 connection from the block and then based on the traffic destination send the traffic out through the vlan port to the ToR switch in the destination subnet?

So i’ve been going through Google searches to find an answer whether Cascade Lake vs Ice Lake can coexist within the same cluster. Unfortunately no luck. So i hope this forum can help me answer this question.My concern is that i was made to understand that Cascade Lake and Ice Lake CPU architecture is different, thus that may pose a performance problems to VM even if the nodes can coexist within the cluster.So the question is, can NX-G7 and NX-G8, which will run on different CPU archtiecture coexist within the same cluster and will it cause any performance issues if this is possible?It would help if you can point me to a KB article or any article for that matter to explain this.Thank you in advance for the help……..
