Will a VM's MAC Address Change if it migrates from one node to another?

Howdy, We have a VM that is licensed by hardware. We needed to do some after hours work on the network so we shut down the VMs and cluster. When it came back online the software unlicensed itself. Looking at the 4th bullet point has be wondering from this KB: How to set MAC address for VM NIC on AHV cluster Not finding much luck to my question but I was curious if the NIC MAC changes if it moved from one node to another when it came back online? Also, is there anyway to see if the system had a prior MAC NIC? Thanks,

Ansible K8s cluster deployment failed to deploy the ntnx dvp

Hi guys, Currently working on Ansible to deploy K8s clusters through Karbon and i got a fatal issue. Ansible is version core 2.12.9, PC is 2022.1, nutanix.ncp collection has been tested in version 1.6.0 and 1.7.0 and there’s absolutely no traffic denied between ansible and PC (to sum up, everything is opened). I use this playbook, based on example provided in ansible-doc (i also tried the example, and i got the same errors in any cases) ###EDIT : i can’t add code in this post, got a banner Something gone wrong everytime ### Here’s the logs when the playbook fails (after ~5min running, from PC, ETCD deployment get stuck at 8%) : ###EDIT : i can’t add code in this post, got a banner Something gone wrong everytime ### Moreover, K8s cluster deployment through PC GUI is working smoothly. Does anyone got an idea to fix the “failed to deploy ntnx dvp” error ? Thanks a lot :) Gael

Host updates, firmware, bios, ESX, etc

Our current Nutanix infrastructure has been a bit neglected for a while, AOS, PC, NCC, etc have been kept up to date but not firmware\bios or hypervisor so I need to get these done. Current infrastructure is nothing massive, two clusters one 4 node one 3 running on NX-8035-G6 and NX-8035-G7, both are AOS 5.20.4. We have one PC running at the latest version and its sitting on a separate Management vSphere cluster along with vCenter. Hypervisor is currently ESXi 7.0 Update 2a 17867351 on all hosts, this is Standard Edition so NO DRS ☹ My plan is to upgrade the firmware and BIOS etc via the LCM on the smaller of the two clusters. I have freed up one host so there aren’t any VM’s on it apart from the CVM. I take it I can just run the LCM to do the firmware updates on that host and let it do its thing without having to do anything else, it’ll shut down the CVM maintenance mode the host and restart it? Once that is complete I want to upgrade ESX on that host. I have checked the compatibility

LCM failed performing action wait_for_services_startup

Hello, I recently tried to run an LCM upgrade of AHV Hypervisor el7.nutanix.202011005.30417 to version el7.nutanix.20220304.242 and ran into an issue where a failure occured during the upgrade and one of my clusters is now stuck on “Detaching node xxx.xxx.xxx.xxx from metadata ring” at a little bit of a loss as to where i can move forward from here. I am unable to launch the console for the CVM and cannot ping the CVM. I apologize for the formatting on this post. This is my first time posting and I am not too sure how to best format or attach screenshots. shown below.

Nutanix lcm screen does not come out and loading continues

Hello, I am conducting a test using NX-3050 equipment I know it's an old Node-Model and I have previously installed it with AOS 5.20.2.1 As you can see now, we are going to test the upgrade using LCM in AOS 5.10.11.1 LCM 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 screen No 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

How to Size a new Nutanix cluster from VMWare to Nutanix

Hello All, I'm working with a customer on a new solution design the customer has a VMware workload and we plan to put AHV, I want you to advise me on how I calculate the storage requirement, Let’s say the customer workload is about 170 TB how do i size the cluster storage Also, I have some questions related to storage sizes if I have 3 nodes cluster each node with 10 disks each disk 4 TB (numbers for examples only) that means total raw storage is 120 TB we will go with RF2 which means 1 node is out of our usable capacity calculation So what is the usable capacity here after the 1 node for failure and the Raid used in the cluster creation, also what else should be conducted from the storage in storage planning?

Karbon and Prism Central Management for K8s Cluster

Hi I’m currently working on RBAC rights for Prism Central but also for entities (VM,Apps...) In my understanding and in the documentation, i saw that you have to be User Admin on PC to get full rights on K8s cluster. In that statement, how does Karbon acts on K8s cluster rights while it deploy a new cluster ? (For instance, if you are a Viewer on PC you can’t connect to K8s cluster, if you’re User Admin, you can do whatever you want. ) Best regards Gael

VM Disk Greater Than 2TB Issue

We’re running 2 clusters which are pretty much configured the same running ESxi 7.02 AOS 5.20.4 LTS both running on nutanix hardware. One cluster is totally fine no issues but the other you cannot create a virtual disk greater than 2Tb! The issue only came to light when we had to move a VM off to another non-nutanix host for a few days then when we went to vmotion it back it errored complaining about the disk being greater than 2Tb, it is its nearly 6Tb as its a fortinet analyzer. I’m pretty sure when the VM was sat on the nutanix cluster its disk was greater than 2Tb and it was thin provisioned with a capacity of 7Tb when it was created! So you can’t move anything to any of the datastores that are greater than 2Tb and you also can’t create a new disk greater than 2TB. Also if you take a look at the datastores details it says maximum VM disk size 2TB, on the other clusters datastore it says 62Tb. It's getting to be a bit of a pain as the fortinet analyzer is sitting on a box we want to

Phoenix Failed to load squashfs.img on HPe DL380 Gen10

When running foundation from the same network as the CVM/AHV host should be in, I’m getting this error. Phoenix Failed to load squashfs.img. I can’t ping the gateway, and it looks like during the bring up it’s unable to create bond0 with the NIC, which is 534FLR-SFP+.

Transfer Nutanix Certification to Different Account

Wondering if it is possible to transfer a Nutanix cert to an alternate account? Since we cannot register Nutanix accounts with personal email addresses (Gmail, Hotmail etc) my Nutanix cert is linked to my Nutanix account with my current employer who I am finishing my employment with today. Since I’ll no longer have access to that email after today, how can I continue to access my Nuatnix account / my Nutanix certification? I do happen to have another Nuatnix account ready to use, but cannot see a solution. I am based outside of the US without the ability to call US phone numbers. I called the Nutanix support number available in my country but it went through to “technical support” who informed me they can only provide technical support and cannot transfer me to Customer Support - instead giving me a US phone number to call which I cannot use.. Given the time sensitivity I doubt I’ll get a solution in time but figured it’s worth asking the question here just in case.

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.

Copy or Storage Vmotion Very Slow

I have a 8 nodes nutanix with vSphere 7 deployed. I’ve created 2 new storage container with compression enabled and map to the nodes. I test to copy the file that i uploaded to the default container to the new storage container presented as NFS datastore...it was very slow. 5GB took 2hrs. Then i tried storage vmotion of a VM reside on the new datastore to another new datastore. A 10GB VM took 20 minutes. If storage vmotion from the default container to new datastore, it fails.
