How to upgrade Cache SSD for bigger capacity on AHV cluster

I have a cluster of 7 nodes of which 2 are Lenovo HX3320 with 480GB SSD + 6 2TB HDD and I need to replace the 480GB ones with 3.86TB or larger, due to recent growth in the number of nodes in the cluster. What is the correct procedure to make the change?

API Token for Nutanix Automation Security

Hello,I’m new to Nutanix, we just started to work with the system and I have a small problem.Unlike VMWare Nutanix doesn’t have PowerShell Module so I’m working directly with the API.My problem is that I want to create automation for set categories and tags based on variables like the disk/VM name etc. I can’t find a way to use a token for security reasons and not send the username and password as Base64 which isn’t secure.

Windows VM does not detect local vdisk

Hello Team. <issue summary>Windows server 2016 VM was restored after async DR to another cluster. If I check through Prism or CVM acli, the local vdisk looks normal in the list.However, some local vDisks are not recognized inside Windows OS.The disks are not identified in "Create and Format Hard Disk Partitions" at all.The weird thing is that other local vdisk looks normal.VG attached in DAS way looks normal vdisk.async DR was performed from AOS 5.20.5 to AOS 6.5.5.5. <Current Environment>- AOS 6.5.5.5- OS : Windows Server 2016 Standard- VirtIO : 1.2.3- vdisk bus : scsi If you restore it from the AS-IS cluster and check it, the local vdisk looks normal on the OS.In a TO-BE cluster, some local v disks are not recognized by the OS.Has anyone had a similar experience?If you have any, please tell me about the solution or cause. Thank you.

NCI cluster with Cisco UCS domain-mode deployment.

Hi Team,We are trying to deploy NCI cluster and env is Cisco C series M7 connected fabric interconnect, UCS domain mode deployment. Nutanix AOS/AHV- 6.5.5.7 version. 1. Looking for information on how many MAC pool required . As the document says to create a default MAC pool and unique MAC pool. is it 2 pool required.2. Normally there will be separate MAC pool for each FI /Fabric interconnect which will be used for server based on connection. For instance, server A has 2 NIC and 1Each connected to FIA and FIB. Both NIC cards will get MAC ID from deferent pool. In Foundation only one MAC pool can be used and that should be default MAC pool. do we have create 3 Mac pool default , MAC-A and MAC-B pool. If yes, were we can provide MAC-A and MAC-B pool info when deploying.3. Regarding VLAN created for NCI cluster in UCS Manager. If we create multiple VLANs, ex for CVM/ AHV, for VMs. How /where we can tag them. As in Foundation only one VLAN can be used.4.  Regarding UCS manifest file vi /hom

Sysprep for VMs deployed from template

Hi,I have a Windows server VM. I don’t have a Prism Central and have mounted the windows server disk to image services in Prism Element. I am planning to deploy future VMs from the template. I am confused is it necessary to run sysprep after deploying a new VM from the template. Hovewer, i have done sysprep of the base VM before mounting it to Image service.Also please comment on Cloned VMs. Thanks in advance.

Requesting Compatibility: Including Cisco B200 M5 as Compute-Only Nodes in an Already-Existing Nutanix Cluster

I am currently operating a Nutanix cluster with Cisco UCSC-C240-M7 nodes. I am considering expanding this cluster by adding two Cisco B200 M5 servers as compute-only nodes. Before proceeding, I’d like to confirm the following:1. Is it possible to install AHV Hypervisor on Cisco B200 M5 servers and integrate them as compute-only nodes into our existing Nutanix cluster?2. Are there any specific configurations or firmware requirements for the B200 M5 servers to ensure compatibility with Nutanix AHV (the blades are UCS managed)?3. Can you provide any documentation or guidance on the best practices for this type of integration?Thank you

AHV ISO Image Fail

I have some HX1021 nodes that are bare metal right now and need to have AHV installed. I’ve tried multiple AHV ISO images and AOS ISO images, but every time I try mounting them to install them, I get this error: “[6.486252] pstore: unknown compression: deflate.” I’ve tried multiple versions of these ISOs and have tried downloading them from my local computer and from my jump host. I don’t believe they are getting corrupted when being downloaded. Anyone have any advice?

AOS with Cisco B-Series Compatibility

Hi there, I have two Cisco UCS B200 M5 servers connected to two 6200 FIs. I have deeply searched in the documentation of Nutanix and found that the only supported B-series server is the M4, but its supported AOS is EOL already. And I know that the minimum number of nodes is three for a Nutanix cluster to be deployed. However, my question is: is there any possible way I can install AOS on these servers? Thanks,Osama

Packer: "press any key to boot from CD/DVD" issue

Hi,I have a successful gold image build for Windows Server 2022 that runs all the way through - building from ISO’s in the image library all run from Packer and ending up with a sysprep’d ‘disk’ in the Image library able to be deployed from…  All apart from I manually have to catch the first boot of the Packer build and hit ‘any key’ to enable the initial boot from the attached ISO.In the ESXi version of the Packer plugin, there’s “boot_command” and boot_wait” options, but nothing like this seems to exist in the Nutanix Packer plugin (0.9.0)Has anyone got a solution to this problem?  Seems pretty basic!Thanks in advanceTim

Display resolution in Windows Server 2016 (AHV-VM) stuck to 1280x1024

Ok, yesterday one of our many Nutanix clusters was upgraded to 5.15 LTS and I started to create a new Windows Server 2016 template using UEFI-configuration.   Now I am stuck at display resolution of 1280x1024 and change is not possible, because it is grayed out. Nutanix Guest Tools from 5.15 LTS and VirtIO 1.1.5 are installed.   Is this bug known and does there exist a work-around?   What about 5.16 STS? Is it fixed there?   Thanks for any reply.   Regards, Didi7

Need help on an old cluster, Zookeeper won't start

Hi AllI have recently inherited an old (el7.nutanix.20201105.30281 is the version maybe?) 4-node Nutanix cluster and very soon after first looking at it and raising myself some tasks it has decided to stop working! I do not have support (turns out that expired a couple of months ago) and while I do intend to resolve that situation I just need to get the thing back online ASAP as it runs some critical servicesThe initial problem was caused by one of the nodes running out of inodes on the root disk. I cleared this down (it was just a LOT of emails in the spool) but the prism console was not available afterwards. Had a quick look online and restarted genesis (allssh 'genesis restart') off the back of that but it did not helpThe problem seems to be with zookeeper, in zookeeper.out I just see a lot of this2024-06-24 15:51:33,093Z:26630(0x7f4343398700):ZOO_INFO@zookeeper_interest@1926: Connecting to server 10.6.232.32:98762024-06-24 15:51:33,093Z:26630(0x7f4343398700):ZOO_INFO@zookeeper_inte
