Hello again CE community! I'm running a Dell R730 with these specs: 2 Sockets 8 Cores Each Socket 256 GB RAM I'm running ESXi to run a 4-node cluster and want to parcel the CPU and Memory evenly among the 4 CVMs. Q1: Based on this, what should my CVM CPU/RAM settings be? Q2: When I allocate vCPU and RAM for VMs, how do I translate a bare-metal config spec e.g. 4x WS2016 8 CPU, 32 GB RAMto Nutanix VM specs, based on these constraints? I just need an example to shine light on how to break down the physical to esxi to nutanix CVM to VM specs. Thanks in advance, Brit
One of my physical disks failed because it had a loose connection in the drive bay. Where do I reset a flag for the failed disk or something similar that Nutanix tries again with the same disk?(xpost: https://www.reddit.com/r/nutanix/comments/j4jl4f/how_to_reset_failed_disk/)
When it comes to migrating your environment into AHV the recommended way would be to use Nutanix Move. Much being said and written and more is coming. Nutanix understand however that using Move may not be an option for whatever reason. Freedom of choice is important after all, right? In case you are looking for an alternative way to migrate your VMs’ disks into AHV then keep reading.The article referred to in this post covers three scenarios:Source virtual disk files can be accessed directly by the Acropolis cluster over NFS (or HTTP). This scenario is generally possible when: The source environment is a Nutanix ESXi cluster. The source environment is a Nutanix Hyper-V cluster. The virtual disk files are hosted on an NFS server and the Acropolis cluster can be provided access to the NFS server export. (Common in non-Nutanix NFS based ESXi environments.) Previously exported virtual disk files are hosted by any NFS or HTTP server and the Acropolis cluster has access to them. Source vi

Quick tip of the day. Did you know that you can integrate IPMI with the Active Directory? Note: The default timeout is set at 0, which results in an error message HTTP 500 - Internal Server Error. Make sure to update it to 10. Select the User and then select Add Role Group to configure the Role Group. (Be sure that it matches an existing AD group name.) When logging into the IPMI web console, use the following format to log in: username@domain. Should you find yourself with a task too big to be handled manually such as configuring the same but on a miriad of nodes there is some help available. SMCIPMITool is a utility by SuperMicro. You can create a script to go through all your nodes’ IPMI interfaces and join them to the AD. For a complete set of steps see KB-2860 How to configure IPMI Active Directory Authentication for Supermicro platforms. For commands list and use cases see SMCIPMITool User’s Guide.
The upgrade process for the VCSA from a major release to another is as follows:A new VCSA with a temp IP is created in the vSphere host/cluster by the upgrade process. The upgrade process migrates the config/data from the old VCSA to the new one. The Old VCSA is shutdown and the new VCSA is renamed/re-ip with the values of the old VCSA. New VCSA is then rebooted.At this point the new VCSA should have the old VCSA name and IP address. My question for those that have done this already is, how does the Nutanix cluster Prism element reacts to this in regards to its vcenter registration? Will all this be transparent to it or will it see the new VCSA as a new device and create a duplicate entry? I assume the migration process will copy SSH keys and certs from the old VCSA to the new one so Prism won’t bat an eye, but I just wanted to confirm.
Working using CLI is easy, simple, elegant and fast. Every administrator loves scripting and automating tasks using the command line. Nutanix makes Management tasks related to virtual disks easy, simple and efficient using CLI. So, what are the situations in which you might need to perform VM Disk management actions if you’re an administrator? You created a VM with a disk of 250GiB and now you need to increase it to 500GiB What if you need to increase the size of a VM Disk? Created a Disk but now need to clone it to different VMs! Need to create an image from a VM disk? Created a VM with the wrong BUS Type! Do we need to change the index of IDE disk? We all have faced a situation in which we might need to insert an ISO to a CD ROM or eject a CD ROM We have created a Volume Group and now need to manage the disks in the VG Most of these actions can be performed using the Prism GUI but what if we are more interested in CLI approach and want to automate these day-to-day admin tasks Do we
Hi Everyone, I've planed to deploy Spunk on Nutanix on my Company. But i'm newbie in Nutanix, so I have some question about this: 1. Nutanix have hypervisor which I can use is ESXi, HyperV,KVM... so in my case, I will use Esxi and rehat to install Splunk. it's mean I have install Splunk on Redhat which is running on ESXi, is it right? Can i install Redhat directly to Nutanix server (1 node have 4 server?) 2. About the Cluster, Which is control the cluster on VM Host? Vmware vCenter or Nutanix Prism Central? 3. Nutanix have an OS is VM Controller? is it install on Vmware machine or is it a hypervisor? Thanks for all reply to make my clear this stuff.
Hello all,I am trying to do some updates in a dark site. I have configured the webserver and downloaded all the updates on the local server(like in the documentation). But from my understanding of the documentation, you need to do the following steps:Put the necessary files in the web server Replace the compatibility checks for the specific upgrade module Run inventory checks. Upgrade moduleI find it quite hard and time-consuming to do this for each component. Are there any better/faster ways to upgrade a dark site?For example, download all the upgrades and perform only one inventory check?
Sometimes it is very boring to install the PrismCentral VM on AHV after your Cluster runs but it gets buggy. So here are some tips to solve problems there Deploy a Network in your new AHV Environment first Deploy the new VM via Prism Element Homepage Often you get an error with ssl and httpd could not start! Login via ssh to ip of your fresh deployed Prism Central Server Login via nutanix / nutanix/4u sudo -i service httpd status (mostly not started) service httpd start (ignore the ssl errors in the output) Now the new PrismCentral Website should arrive after a while under https://ip-of-prismcentral Login not possible with admin / admin or admin / nutanix/4u? Login again via ssh and nutanix / nutanix/4u to prismcentral sudo -i passwd admin set your admin password and repeat it reboot wait a while login to prismcental and admin / your password Register your cluster in prism element
I've been trying to clear out a entry in the nCLI interface on a CVM without luck. tried the standard 'history -c' and 'events history clear'. Basically I have a value I dont want to show up at the propmt is a user is cycling through the "up arrow history" while in ncli. Anyone with the command?
Dear contributors, We have purchased Nutanix appliances and I am working as part of the IT Security team. We have enforced the security settings on CVM and AHV (STIG, banner, ...) and, as part of our duties, we carry out regular checks to make sure that the security settings have not been altered. For this, we would like to have nominative accounts which are able to connect through SSH and be able to check on the settings of the components. Is it possible to do? If yes, how can we proceed? Thank you in advance for your assistance.
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 everybody, is there any advise how to shut down the whole NX Block? I got my first NX1465 and run foundation and build the cluster with AHV.After the first configuration steps i will power the whole block off to bring the NX into our datacenter. So, i didn't find a "how to". Any ideas/hints? Greetings, Maikel
Hello, All.Good day!! I have an issue and need your help and advice. 1. using 10 nodes, but I want to configure 2 clusters with 5 nodes each. (Composed of RF3) 2.

Hello, We are in the process of moving our VMWare site to Nutanix. With 3 locations i would like some design tips to setup the NTNX sites/cluster(s). I am very new to nutanix. Situation: 3 fysical sites, 2 sites with 4 NTNX hosts and 1 site with 3 NTNX hosts. Every site dedicated fiber connection. The 2 "4 hosts sites" are for production, the 3 hosts site will be otap and/or extra hosts for production. How to design the NTNX cluster(s) with minimal risk of loosing data and the most redundancy. If someone needs more info please let me know grtz

We have a scenario in which we are running VMware vSphere environment on existing servers and planning to deploy a DR site. Is it possible that we deploy a Nutanix AHV environment at the DR site and replicate from the existing ESXi environment at the Production site to the Nutanix DR site somehow? We are currently using Veeam backup and replication for VMware for backup. What is the possibility of such a requirement?
We are planning a major migration from existing 3-tier ESXi over to Nutanix/ESXi (AHV to come later). Due to time constraints in our move, we are trying to optimize how many VM's can migrate at one time. VMware has a few well-known limits on their operations: vMotion operations per host (10Gb/s network) - 8 vMotion operations per datastore - 128 Storage vMotion operations per host - 2 Storage vMotion operations per datastore - 8 If I take a "one storage container to rule them all" approach, I will be limited to 8 migrations at once, as long as I spread out my migrations to 4 hosts. My target will be a 14 node cluster, so I would like to push up to 28 operations, if at all possible. Would it be considered a best-practice to carve out 4 storage containers, knowing I'm still in the same pool, and fan out the migrations to get around these limits? My goal is to saturate my 10Gbit inter-datacenter link. Yes, I like to push the limits (break things?). Would the multi-data
