Prism logs?

Probably a silly question. Regarding Prism Element...When logging in and are greeted with the main page or when navigating to other pages, are there UI logs?

What Host is a Windows VDI running on when running on AHV

Hi,We’re currently moving from Nutanix Hyper-V cluster to a Nutanix AHV cluster. We’re running Windows 10 VDIs on these clusters, currently we use BGInfo to display various settings for our users (VDI name, IP Address, Host Name). On Hyper-v it creates a registry key on the VDI with the Host that the VDI is running on. Does anyone know how i fins this information when running on a AHV cluster..?Thanks

Using cURL to get ‘/Cluster’ endpoint (ex. below). How do I structure my call to return singleattribute, like ‘name’ , ‘uuid’  or version . API query outputs entire tree     https://<IP>:9440/PrismGateway/services/rest/v2.0/cluster/'        "id": "0005d918-7718-830d-60d0-ac1f6b3f9209::6976265073740190217",        "uuid": "0005d918-7718-830d-60d0-ac1f6b3f9209",        "cluster_incarnation_id": 1646073984090893,        "cluster_uuid": "0005d918-7718-830d-60d0-ac1f6b3f9209",         "name": "vaclevsh2100",         "version": "6.1"   2.

How to license Windows Server 2019 running in Nutanix appliances

Hello,I need to create several Windows Server 2019 standard, virtual machines that run in AHV (Nutanix cluster of 3 nodes nx-3170-g8, with 2x16 cores in each node) hosts that i need to buy licenses for. But i do not seem to find a calculation method for licenses).I found that i can go for per core licensing of physical cores (3*2*16 = 96 cores) which would help reduce costs since the total number of virtual cores that need to be configured is more than 200 v-cores.i would like to confirm if this approach is correct? i.e. licensing the number of the physical cores of nutanix appliances? and if anyone did it successfully?Thank you in advance,

VLan tag for CVM Host and Guest

Hi Team,We have three node (NX-8155 ) cluster connected to nexus switch.Vlan Tag for CVM and Host : 600Vlan Tag for Guest/Prod : 10All are in same subnet ( Host IP : 172.21.10.x/24 , CVM IP : 172.21.10.x/24  and Guest/Prod Network : 172.21.10.x/24  )We have allowed Layer-2 on Nexus, trunk port traffic and added both Vlans ( 600 and 10)Question:Can we keep all under same subnet ? If so how can I communicate inter-VLan , for the purpose of CVM to communicate NTP,DNS,Monitoring and Internet. Else Can I keep CVM, Host and Guest in same Vlan ? How this will impact broadcast domain and any issue with congestion. Else Can we have two different subnet range for (CVM, Hosts) and Guest with different Vlan (600) and (10)

Cloud-init with Projects in Prism Central

I created a Project in Prism Central and assigned a bunch of users to it, expecting them to be able to provision their own VMs with cloud-init configs customised to their liking.I found this awesome example code https://www.nutanix.dev/code_samples/create-linux-vm-customised-with-cloud-init/ which shows it can be done with API calls, however, as a user in the Project, there does not seem to be any options in the PC UI that allow me to specify a custom script when creating a VM.Are custom scripts deliberately hidden when using Projects? How are my users supposed to customise their VMs?

What if I Turn off the Manage VM High Availability Feature and Upgrade?

Hello. I have a question about upgrading AOS and AHV.I understand that upgrading AOS and AHV requires restarting nodes one by one, so I need to calculate memory, CPU, storage, etc. and free up enough space.There are customers who are currently using more than 90% of cluster memory.cpu, there's plenty of storage.We recommended turning off underutilized VMs to free up memory capacity, but they said it was impossible.It also says that disabling virtual machine high availability reduces memory utilization to less than 60%.However, it is recommended that you disable virtual machine high availability because it is a feature for recovery in the event of a host failure.If you turn off this feature during an upgrade and an unexpected failure occurs during the process, it can be a problem, right?In conclusion, I would appreciate it if you could tell me the correlation between upgrade and virtual machine high availability.

IOError [Error 28] No space left on device

Hi Everyone,One of the nodes of our cluster suddenly got disconnected. I was not able to ping initially, but after restarting the node and checking if maintenance mode is enabled. Connectivity was regained and all the IPs can be pinged from each other.  Even so, the cluster can’t recognize the previously disconnected node even when all pings are good. Tried restarting the cluster and the local CVM but the error below appears:nutanix@NTNX-A-CVM:192.168.50.182:~$ cluster status2021-07-13 07:34:46,652Z WARNING genesis_utils.py:1304 Failed to reach a node where Genesis is up.

Dealing with disaster…how does Nutanix respond?

Things won’t always go to plan and the worst will happen. In this case, we lose 2 nodes from our 9 node rf2 cluster (e.g. one’s down for maintenance, someone forgets and reboots another node at the same time).  Can someone point me at some documentation that outlines how we can recover from this and get the cluster back up and running. Is there any permanent fallout?Thanks.

Mixing HDDs in a node

We have 3 nodes with 2x960GB SSD and 4x4TB HDD.We need to expand storage (and storage only as it is going to be used to store cold data - we do not need additional processing power or RAM)Question 1: We simply added two 12TB HDDs to each node. Now each node has 2x960GB SSD, 4x4TB HDDs, 2x12TB HDDs. Everything is working fine, but we were told that this is not recommended. What is the problem with this configurationQuestion 2: Assuming the configuration in Q1 is not recommended and we want to end up with each node having one type of HDDs. We were told that we can upgrade the existing 4TB HDDs with 12TB drives. What the right procedure would be:  a) Mark one 4TB drive for removal, remove it, insert 12TB drive in place of removed 4TB drive. Repeat 4 times for a node. Resulting configuration - 6x12TB HDDs per node  b) Add two more 12TB drives first, then mark for removal and remove four 4TB drives (one by one). Resulting configuration - 4x12TB HDDs per node (preferred configuration by us)T

inter_cvm_connections check in NCC 4.X

I have a question about the new version NCC 4.X and AOS 5.20.X.When I upgraded the cluster from to AOS 5.20.2.1 from AOS 5.15. and NCC upgarde to 4.3.0.2. I found the the ping_hosts.INFO file in /home/nutanix/data/logs/sysstats has disappeared and I cannot check the latency between CVM every minute. There is only the ping_gateway.INFO file to check the latency between CVM and gateway. But there is also ncc alert that the inter_CVM_latency is high. So where can I check the detail latency information between CVM in the new verison?

Upstream connection error: reset due to connection failure before headers

Hey guys, newbie to the forum here. I recently setup a ce version of Nutanix in our work lab environment on vsphere. Up until last week I was able to log into the gui, I can still login via putty.When I try to log into the gui now, via xxx.xxx.xxx.xxx:9440/console/#login - I get the above message.I have also had the message "server is not reachable”I did think about trying the install again but thought I would ask the question first and see if anyone else has had the same problem and if so how they got around it?  Thanks in advance.

How many node fail can you withstand?(4Node Cluster - RF2)

 Hello. I have a question about the RF2 function.Currently, it is composed of 4 nodes and RF2 as a cluster.As far as I know, RF2 has 1 node fail.If so, shouldn't the Data Resiliency Status drop to Fail?However, although one node has failed, the Data Resiliency Status is still OK.In fact, the CPU, Memory, and Storage usage in the current cluster is low.Currently only 3 nodes are active CPU is 20% Memory is 40% Storage is 18.5%.Why is the Data Resiliency Status Ok?Is there any problem with the service even if one more node is currently turned off?Or will the cluster die if 1 more Node dies?If you don't die, I want to know why.
