Hi I have a question in the Nutanix enviroment.I need to change control for the ssh to CVM so that just some IPs can access to avoid some intrusion access.I checked the <Nutanix security Guide> and there are some descriptopm in TCP Wrapper Integration, But after I changed the file of /etc/hosts.allow to include just the allowed IPs and CVM management subnet. But It will be changed to default after the cluster security config schedule(by default daily.) Is it possible to change the sshd allow list to achieved this goal? there are security requreiments for the enviroment. thanks.

We have two Prism Central in our environment. Is there a way to link two PrismCentral ?

I am trying to figure out how to pass variables to a calm runbook through a JSON post via the API. /api/nutanix/v3/runbooks/runbooku_uid/run{ "kind": "runbook" "spec": { "args": [ { "name": "network_name", "value": "Test123" }]}} 

What is FLR? What’s the purpose of the /flr endpoint? 

Hello, We have the VM with the file serber on installing on one of the node of our Nutanix. For now the size of the disk is 3.5 TB, but we wanted to extend this size up to 4.5TB. Is somebody knows if VM will work correctly with the such big size of the disk?

Want to know the maximum number of VLAN(802.1q) interfaces than can be created on each bridge of AHV. I cannot find any documentation or matrix about this. Thank you.

I ma a dark-site NX-3060-G7 cluster. I need to know who is the manufacturer of the firmware for this machine so I can update the LCM firmware. 

Hi everybody,We’re doing a slight restructure in our DC and in thus need to change the default gateway used by a Nutanix cluster (3-node cluster).I’m aware of the following guide:https://portal.nutanix.com/page/documents/details?targetId=Advanced_Admin-Acr_v4_6:ip__ip_reconfig_web_c.htmlBut isn’t it at all possible to change something as simple as just the Default Gateway without such an invasive procedure requiring downtime?The part of the article on how to do it manually is...Non-existent:https://portal.nutanix.com/page/documents/details?targetId=Advanced_Admin-Acr_v4_6:ip__cvm_ip_address_reconfigure_t.html

What is better, 4x960GB SSDs per node or 2x1.9TB SSDs?We currently have 2x960GB SSDs and need to double the capacity. Cost aside, any benefits of one configuration over another?

Hi community, I have some Qlogic 10G/25G NIC cards in my cluster which as I understand are not “supported” however seem to be detected correctly to some extent. Manage_ovs show-interfaces displays the output below which leads me to belive that the driver is loaded. However, currently those ports are connected to a 10G switch and so the speed and the operational status are not correctly working. Is there a way to set these by hand?  manage_ovs show_interfaces    name  mode  link speedenp5s0f0 25000 False  Noneenp5s0f1 25000 False  None    eth0  1000 False  None    eth1  1000 False  None    eth2  1000 False  None    eth3  1000 False  None    eth4  1000 False  None    eth5  1000 False  None    eth6  1000 False  None    eth7  1000  True  1000 When I add those cards to a vritual bridge I get the error message below. manage_ovs --bridge_name br1 --bond_name bond1 --interfaces 25g update_uplinks2021-03-31 18:05:50,402Z WARNING manage_ovs:437 Interface enp5s0f1 does not have link state2021-03-

Hi folks,Can I convert HC node to CO node? if yes, how?

How do I check hot and cold data by virtual machine? I'm going to migrate the virtual machines of the existing nodes to the node that I'm going to buy new ones. So, I'd like to check the hot and cold data of the virtual machines, respectively.

I’m tuning RBAC to provide Self-Service users with just enough permissions for CRUD operations on VMs and Recovery points using the API and custom roles.When trying to create a VM, I see the following message with the “VM Template” radio button greyed out: There are currently no VM templates available in the projects that you are a part of. So, where is the association of VM Templates to a project? I created a couple of VM templates by creating the required images and adding them to the catalog. Is there some special permission required for this (because playing with RBAC has made this greyed out)? 

Good morning All   I have a bit of an NGT issue, the Prism Central alerts me to say some VMs need a NGT upgrade, when I go to upgrade them I see the message “NGT can only be upgraded on 0/1 VMs which have the available upgrade of NGT”   Review and confirm buttons are greyed out so I cannot continue - what does the message mean and what do I do to get it to work?   Many thanks   Eric

Looking at the site below, I understand that ESXi 7.0 is supported. But I'm not sure if vCenter 7.0 is supported.https://portal.nutanix.com/page/documents/compatibility-matrixIs it a problem to use vCenter 7.0 ?Also, where can I find out which vCenter versions are supported?

I am trying to move a VM from EXSI to AHV. When I try the move I get the error “VMTools is not running.” any suggestions?

Hello, I tried to change the Prism admin password today, but the admin account keep locked automatically. So every time I have to reset the admin account from a CVM, but it gets locked after 5 minutes.  

I was wondering what best practice is for defragmenting guest OS on a Nutanix node.  I am running ESXi on the nodes.  I have looked all over but I cannot find anything that tells me definitively the best practice.

I want to create to vm’s using REST API by selecting one of Catalog Items.I can create vm via catalog items via Prism Central Dashboard.When i try to create vm via REST API, i can not find any reference to give Catalogs Items vm  template there.How to give vm templates in vm creation using REST API?

Hi folks, In VMware, we need to enable EVC to be able to do vMotion between diff processors, what about AHV? what should be done or is it working smoothly?

HiI have 4 Nodes cluster with the detailed network belowVLAN1000 : IPMI Usage (192.168.255.x/24)VLAN20 : GuestVM & Internal Cluster Network (192.168.2.x/24)I was using eth3 and eth4 in bond br0-up in bridge br0 (vs0) And then i’m adding a new vlan (VLAN30 : 192.168.3.x/24) for separating GuestVM network from Internal ClusterI am using eth0 and eth1 in another bond (bond br1-up in bridge br1) connected to my switchport mode access VLAN30. The problem is, when i created VM using that network (vs1), my guest vm cant ping anywhere even the gateway of its subnet. But when i test my laptop that connected to the switchport mode access VLAN30, my laptop can ping the Gateway.Here i give the detail of my topology and uplinks configurationTopologyUplinks of each hostsvs1 configuration Perhaps someone can enlight me maybe i missed something here when i’m trying to configure this? Thank you.

We have numerous clusters and each have their own hardware platform (and in a couple of cases, we’ve even mixed hardware models within the same cluster). Our current Nutanix footprint;VENDOR         MODELS        NODE COUNTSuper Micro    NX-8155-G7    12Super Micro    NX-1175S-G6    7Super Micro    NX-3060-G7    6Dell                 XC630-10         14Super Micro    NX-8035-G7    12Super Micro    NX-8035-G6    36Is there a preferred or recommended solution for hardware monitoring and alerting? For instance; Dell OpenManage (DOM) or Supermicro Server Manager (SSM). I don’t readily know if either would support the others solution (like DOM supporting IPMIs or SSM supporting iDracs) Or, would Prism Central (and Prism Element) be sufficient for hardware monitoring and alerting?We currently have and are using DOM but not for the SuperMicro hardware so I’m wondering if I’m potentially missing out on a better solution or not.

Hello!I have an LCM inventory task that seem to be stuck in my cluster. It is stuck at 5% since 2 days ago. Please, help me to solve this issue. The following command shows that there's not LCM process running:$ acli task.list include_completed=false | grep lcm

Hi!I am wondering, if there is a quick way to restore from a failed ESXi upgrade.Imaging you have fired up a ONE-Klick-Upgrade of the ESXi image, and (as see with ESXi7.0U1GA) the hypervisor is not boot up again.At ESXi level i can backup config and restore config after a plane install. But what about CVM?Setting up the whole node with foundation is a nightmare, if the node is already installed in an customer environment, and can’t be discovered.The best way would be, that the foundation within a cluster could deploy a CVM to a plain ESXi and rebuild the cluster-node from the information stored in the cluster...

HI Team under Prism we’ve created a few VM’s (windows), one of VM is our File Server, current configuration is IDE disk 1TB, (60GB OS, 900GB shared folders). probably is better to create one virtual disk 60GB on OS and the second virtual disk as storage (1TB) or more.question is how to shrink current IDE disk from 1TB → 60GB, and if IDE should be change on SCSI disk, what Nutanix recommended?instruction to shrink disk IDE->SCSIthanks Dariusz
