Installation & Configuration

Hi, We want to throttle replication bandwidth. In the Remote Site config in Data Protection, the option is to throttle B/W in MBps.  Is this Mbps (megabits per second) or MB/s (Megabytes per second)?  The unit implies megabytes per second (i.e. the "B" is capitalised), but that is normally a unit of throughput not bandwidth... Obviously there is an order of magnitude in difference so its important we interpret this correctly!

Hello, Lately I have been adding the Nutanix SCOM Management Pack version 2.4.0.0. From the start on it worked fine as I handed over the Cluster information via Nutanix Cluster Discovery. But now, a few weeks later, SCOM will not display any performance data of the clusters anymore. I am not able to find out where exactely caused this problem. I have different Clusters AHV and ESXI as well as multiple OSVersions running. Currently SCOM displays only one Cluster with it's information. From the other Clusters, there is no performance data shown. All other clusters were discovered correctely (and the same way) but won't show their data anymore. My situation looks like this - this dashboard is showing the clusters information. All other clusters (and their nodes) are not showing data - the dashboard stays empty. What could have happend that the data is not reaching SCOM or SCOM not displaying it anymore? Could it be too much Clusters on my system? I have 13 Clusters with (together)

I'm running Prism Central 5.7.1.1 and have recently upgraded 6 of our clusters to 5.5.7.1. Of those 6 clusters, 3 of them are still showing an Upgrade Status of 'Upgrading' in Prism Central. It's been a over a month for one cluster and I've restarted Prism Central appliance to no avail - has anyone else seen this?

I've seen servers that have active and inactive in replication . when I check the replication settings. there are inactive and active vm's in job. so i didnt understand that what is mean inactive vm's. can i delete it . if there is no replication in the other region, they take up storage space and if I delete them I can save space from storage space Also i have another question is on vcenter 6.5. i see free size is 4 tb but on nutanix mangement screen free size is 11 tb. why do i see it so different. If the virtual machine is deleted, there is a space recovered on the storage side.

Hey everyone, I am required to upgrade from ESX 6.7 U1 to U2 to resolve a bug that prevents me from going back more than 8-10mins to look at VM performance, however, Nutanix has only just now tested U3.  My question is: Has anyone migrated to U3 yet and if so how has it been so far?

We are using a Prism Central Installation with several Clusters in different Sites. For the Administrators on Site, we want to configure a user on the site based prism elements instance, which is a viewing User, with the following additional permissions on the local cluster / Prism Elements: Viewing, Power on and off for all virtual Machines and also a one click shutdown of the whole cluster in case of power outages. We don't want to use the Prism Central User Configuration for following reasons: Prism Central is not accessible in case of line outages or power failures in our sites. And for security reasons and limited skills of the staff on site, I really appreciate not to give admin permission to the site staff. Any Idea, how to deal with this situation ? Thanks Oliver

Hi Team, We have multiple Nutanix clusters with Dell XC servers installed with ESXI servers. We found an user account "PTAdmin" present in Dell iDRAC servers. Is there anyway to disable the account from CVM or Hypervisor since we have 100+ nodes in the infra. Thanks.

Is there a minimum or recommended switch port buffer size? I plan on using eth0 and eth 1 to be connected to two different 10G switches but was wondering if there is a minimum buffer size or switch port requirement?

Hi all, A network security audit on a customer infrastructure reported a vulnerability on the cerebro http (port 2020) who is open on http in every CVM and without any security prompt.Some sensitives informations are visible : - AOS version : el7.3-release-euphrates-5.10.7-stable-... - VM Names  - Protection Domain names  - Witness ip address   - ...  Is there’s a way to secure this component ?

Hi, As per title i am wondering about encryption when we are using ESXi hosts and Nutanix together. We would like to encrypt the VM's and maybe Data-At-Rest encryption. We have currently 3 nodes in a block with 3 ESXi hosts and i wonder what the best practice is about encryption? Is it possible to encrypt the data both via Nutanix and vmwar software/KMS? Is it possible to encrypt only the VM's via VMware encpryption method and use the KMS directly via VMware or should i use the prism management? Does it matter in a Nutanix way if you choose to set up the KMS and encrypt the Data from the vSphere instead of doing it in the Prism mangement? Thank you in advance.

There is an ever-increasing chance that the next time you will need to add a node to the cluster or build a brand new cluster using new nodes – they will be bare metal nodes. What that means is that there is neither AHV nor CVM pre-installed on the node (unlike with factory imaged nodes). The process of imaging differs slightly from handling a factory imaged nodes hence this post. Bare metal nodes might come with a Discovery OS - small footprint software which allows for the node to be discovered by AOS 5.11 and later and thus imaged by an existing cluster CVM. When building a new cluster standalone (bare metal) imaging is performed from a workstation with access to the IPMI interfaces of the nodes in the cluster. Imaging a cluster in the field requires first installing certain tools on the workstation and then setting the environment to run those tools. This includes setting up Foundation VM and uploading Nutanix software images to the Foundation VM. Now follow the guide and let the i

Hi   I want to monitor our Nutanix environment by Nagios XI. Is there a neat guide on how to do this?   Thanks Jeru

Hi there, i need some help with my Dell OptiPlex Micro Cluster. I wanted to build up a four node cluster but everytime i try to install the Nutanix CE, right at the finish line it says: “Waiting for the Nutanix Controller VM to start up………...…” followed by: “A Problem was encountered. Please review the contents of /home/install/firstboot.out for details, and refer to the documentation or the Nutanix NEXT community for next steps. Press <Enter> to return to the login prompt.” Now if i restart the installation and try to repair the CVM this error appears: “ FATAL: AN exception was raised: Traceback (most recent call last): File “./phoenix”, line 96, in <module> main() File “./phoenix”, line 74, in main params = gui.get_params(gui.CEBootDiskConfirm) File “./phoenix/gui.py”, line 1675, in get_params if guitype(args=args).skip_get_params:  File “./phoenix/gui.py”, line 687, in __init__ self.boot_disk = self.get_ce_boot_disk() File “./phoenix/gui.py”, line 772, in get_ce_boot_di

Sorry if this topic has already been covered. I have been trying to use the new "Portable Foundation" app that runs on windows to image a cluster without using a VM. Every time I try (three so far) I get errors that the IPs I have provided are already used. I am using a flat switch and the 10G and 1G are unplugged from the customers switches. I have tried with my laptop in and out of airplane mode, with the firewall on and off and still receive the errors. The only difference is that each time I try, the listed IP conflicts are never the same. It will tell me in the first try that x, y, and z are in use, then the second time it may say that a, b, and y are in use. Any ideas? I really like the idea of this app working. Thanks, -David

Hello, If I have 3 Nutanix nodes and I cluster them together. How can I make a separate VPC for a test stack and a separate VPC for a Production stack? So that way I can build my VM's on the test stack and once they are good to go...I can do the same steps on my Production stack. I would like to have 2 isolated stacks for testing and production. Is this possible? Thanks

For a customer i'm managing a AHV cluster. One of the virtual machines needs to have direct access to a network interface for monitoring traffic (port mirroring). Is this possible with the current releases of AHV? With kind regards, Ruud

According to the documentation, Backplane traffic segmentation is not supported in a configuration for "ESXi clusters in which the CVM is connected to a VMware distributed virtual switch" . What I'd like to understand is whether this is related to technical reasons, or it is just a configuration limitation of the CVM installer/Prism management? So far I counldn't find a comprehensive guide/document about setting up a Nutanix cluster with vSphere distributed switches, and nodes with 2x10gbps each. It doesn't seem to make sense to me to set this up with standard swtches (i.e. no Network I/O control) where all traffic (VM, storage, vMotion, ...) use the same physical uplinks.

Warning: Use of Phoenix to re-image or reinstall AOS with the Action titled "Install CVM" on a node that is already part of a cluster is not supported by Nutanix and can lead to data loss. Use of Phoenix to repair the AOS software on a node with the Action titled "RepairCVM" is to be done only with the direct assistance of Nutanix Support. Use of Phoenix to recover a node after a hypervisor boot disk failure is not necessary in most cases. Please refer to the Hardware Replacement Documentation for your platform model and AOS version to see how this recovery is automated through Prism. What is Phoenix? Phoenix is an ISO-based installer that you can use to perform the following installation tasks on bare-metal hardware one node at a time: Configuring hypervisor settings, virtual switches, and so on after you install a hypervisor on a replacement host boot disk. This option does not require you to include AOS and hypervisor installers in the Phoenix ISO image. Installing the Controller V

I just deployed Prism central scale out on my ESXi cluster and see that the two additional PC appliances have an iso mounted to their CDROM drives. Does this need to stay connected? I’d like to spread these 3 appliances across different datastores. (And ideally, I’d like to move these across sites but I understand that this is a future feature: https://next.nutanix.com/product-ideas-61/multi-cluster-scale-out-prism-central-28305)

I’vejust set up AFS 3.5.5, I’ve enabled SMB protocol and the FS joined AD. The home share has not been created! Why?  

Hi, I'm planning a 3 node Lenovo 2320-E node. The most it will ever grow, is to a 4 node. Each node has a 4 x 1/10Gb BaseT network card (IMM/IPMI) connection is separate. The max number of VM's will probably never exceed 16 (Windows 2008R2/Windows 2016 ) The priority of importance in this case is: Reliability Lowest Cost Performance Network Config Option 1 (1 switch 1 GB ports only): Purchase 1 switch with dual hot-swap power supplies. (Not to jinx myself, but switches have a low fail rate) Setup each node as balance-slb, with 4 x 1Gb BaseT Network Config Option 2 (2 switches 1GB ports only) Purchase 2 switches, each with a single power supply Setup each node as balance-slb, with 4 x 1Gb BaseT Network Config Option 3 (1 switch with both 1 & 10Gb BaseT) Purchase a switch that supports mixed 1 & 10Gb BaseT ports Setup each node as balance-slb and use 2 x 10Gb (of the 4 ports) My understanding of balance-slb is I will have 4Gb of throug

Hi, I want to automate the procedure of node imaging. I have exported the configuration file for foundation. Is there command line to image node with configuration file?

Remote authentication is one of those things that once set up correctly just work. We do not notice it, we simply put in our credentials and use it.It takes some understanding and a tiny bit of thinking ahead when mapping AOS roles and permissions to LDAP/AD users and user groups.So where to start?First, follow Prism Element Security Guide: Configuring Authentication to set up remote authentication.Run NCC Health Check: ldap_config_check.For any issues leverage KBs:KB-2066 Unable to Log In to the Prism web console using Group LDAP authenticationKB-3363 Prism: Troubleshooting LDAP Issues for Prism Log On For those of you PowerShell fans there is a little bit of CLI available:PowerShell Cmdlets Reference: LDAPConnection PowerShell Cmdlets Reference: Domain

Hello all, i'm trying to build a very simple home lab so i can get through the NCP cert, hopefully prior to our new nutanix gear arrives at my work. at home i have an i7 8700k, 16gb of ram, and several HDDs. i also have a NAS device. i run windows 10 on my one available machine. my issue is this: i can only feasibly spare 12 gb of ram, and i dont have a dedicated 200 GB SSD, but i have several terabytes of HDD storage available. is it possible for me to get a home lab up and running with this config? using VMWare Workstation or something similar? thanks, Tony
