 When imaging fails for one or more nodes in the cluster, the progress bar turns red and a red check appears next to the hypervisor address field for any node that was not imaged successfully. Possible reasons for a failure include the following: A type of failure was detected. Check connectivity to the IPMI (bare-metal workflow). There are network connectivity issues such as the following: The connection is dropping intermittently. If intermittent failures persist, look for conflicting IPs. [Hyper-V only] SAMBA service is not running. If Hyper-V displays a warning that it failed to mount the install share, restart SAMBA with the command "sudo service smb restart". Foundation ran out of disk space during the hypervisor or Phoenix preparation phase. Free up some space by deleting unwanted ISO images. In addition, a Foundation crash could leave a /tmp/tmp* directory that contains a copy of an ISO image that you can unmount (if necessary) and delete. Foundation requires 9 GB

How do i change the name of an ESXI host and CVM in a Nutanix cluster?

I haven’t noticed any messages or communications regarding the recent log4j vulnerability (CVE-2021-44228). Does Nutanix have some formal announcement for customers on the status of this threat as it relates to their product portfolio?

 Leap protects your guest VMs and orchestrates their disaster recovery (DR) to other Nutanix clusters when events causing service disruption occur at the primary availability zone (site). For protection of your guest VMs, protection policies with Asynchronous, NearSync, or Synchronous replication schedules generate and replicate recovery points to other on-prem availability zones (sites). Recovery plans orchestrate DR from the replicated recovery points to other Nutanix clusters at the same or different on-prem sites.Protection policies create a recovery point—and set its expiry time—in every iteration of the specified time period (RPO). For example, the policy creates a recovery point every 1 hour for an RPO schedule of 1 hour. The recovery point expires at its designated expiry time based on the retention policy. If there is a prolonged outage at a site, the Nutanix cluster retains the last recovery point to ensure you do not lose all the recovery points. For NearSync replication (li

The following warning occurred to customer Nutanix.WARN: Cluster cannot tolerate 1 node failure.As a result of the search, we found the following:impact Cluster can not tolerate single node (RF2) or two node (RF3) failure and guarantee available storage to provide data redundancy.The usage warning is 26.93 TiB of the 26.41 TiB recommended usage.The question here is, if one out of four nodes fails,Is it still possible to operate with RF1?Or will the cluster hang up?

Hi,Does anyone use One-Click for rolling ESXi patching where you apply patch bundles, i.e. many patches at once? Using One-Click for an upgrade or applying a single patch is documented and discussed/known, i.e. when you need to apply a single file. I’m specifically interested in patch bundles. Like just now VMware released a bundle of 10 patches for 6.7. Making 10 rolled updates via One-Click for each patch is impractical. While applying via VUM does it fine, but due to manual CVM shutdown, it can only be done manually host by host, watching Prism for Data Resilience to return, hence taking time.I’ll appreciate if you please share you approach to this.Thank you.

Good afternoon everyone.During the integration with Nutanix AHV, I faced the following case -I need to perform the operation of restoring VM to the snapshot state, my questions are:1. how can I do this with API v3?2. may I restore the state of one VM with the snapshot from another one?What are recommendations and best practices exist to do this with API v3? Thanks.

Using the LCM I updated one of our hosts to the latest firmware from G4G5T6.0 to G4G5T8.0, (BMC 3.64 to 3.65) and since then all I get is a black screen with the words, “boot error”I can get into the bios via IPMI and see the boot device, “sSATA P3: SATADOM-SL 3ME” but it just not booting from it anymore. I also could not find any documents on how to trouble shoot it.Could someone point me in the right direction please, thanks!Note, out of the 6 hosts in our environment, 3 have updated fine already and nothing has changed, so a little confused. I’ve also been updating one host at a time.

 You can add a cluster name or virtual facing IP address at any time. To create or modify either value, do the following: Procedure:In the main menu, either click the cluster name at the far left or click the gear icon in the main menu and then select cluster details in the Settings page. The cluster Details window appears. It displays the cluster UUID (Universally unique Identifier), ID and incarnation ID values, along with the cluster name, virtual IP address and iSCSI data services IP address (if configured). The cluster ID remains the same for the life of the cluster, but the incarnation ID is reset (typically to the wall time) each time the cluster is re-initialized.  Enter (or update) a name for the cluster in the Cluster Name field.The default name is simply Unnamed. Providing a custom name is optional but recommended. Enter (or update) an IP address for the cluster in the Cluster Virtual IP Address field.A Controller VM runs on each node and has its own IP address, but this f

 Prism Central (PC) administrators with the "Prism Admin '' role have full access to Karbon and its functionalities. Performing most karbonctl operations requires admin privileges. PC admins that do not have the "Prism Admin '' role (Cluster Admin and Viewer) can only access Karbon to download the kubeconfig and cannot perform any other administrative tasks. See "User Management" in the Prism Web Console Guide for steps on assigning roles.Nutanix requires configuring Karbon users for a directory service in Prism. See Security Management in the Prism Web Console Guide for directions on configuring a directory service.After setting up and testing your cluster, configure role-based access control (RBAC), see Kubernetes documentation for reference. Accessing Locked nodesKarbon protects all nodes in a cluster. You can access nodes in a Kubernetes cluster using an ephemeral certificate, which expires after 24-hours. Perform the following steps to get a certificate. Procedure In the Clusters

Xi Infrastructure ServiceAlong with the infrastructure required to support the recovery of on-prem applications, Xi Cloud Services provides the functionality that you require to run the application in the cloud until you can perform a failback. This functionality, made available as Xi Infrastructure Service, is designed to enable you to address application scaling requirements when the primary availability zone is being recovered from a disastrous event.The configuration tasks described here are specific to Xi Cloud Services. To perform on-prem infrastructure tasks, such as VM and category management, you must continue to use the on-prem Prism Central instance. For information about these tasks, see the Prism Central Guide. Entities MenuThe entities menu provides access to all the entities in Xi Cloud Services. An entity is an object type such as a VM, image, floating IP address, or virtual private cloud (VPC). Virtual Private Cloud Management Floating IP Addresses Management Vir

 To replicate entities (protection policies, recovery plans, and recovery points) to different on-prem availability zones (sites) bidirectionally, pair the sites with each other. To replicate entities to different Nutanix clusters at the same site bidirectionally, you need not pair the sites because the primary and the recovery Nutanix clusters are registered to the same site (Prism Central). Without pairing the sites, you cannot perform DR to a different site.  To pair an on-prem site with another on-prem site, perform the following procedure at both the sites.Procedure Log on to the Prism Central web console. Click the hamburger icon at the top-left corner of the window. Go to Administration > Availability Zones in the left pane. 3. Click Connect to Availability Zone.Specify the following information in the Connect to Availability Zone window.   Availability Zone Type: Select Physical Location from the drop-down list.A physical location is an on-prem availability zone (site).

Hello, I have a 3 node 1065 G6 cluster running AHV VMs. I currently have six 6TB EXOS drives and want to expand capacity by replacing them with 12TB EXOS drives. Nutanix says that this is not supported, but has anyone replaced drives to expand capacity? I have no money in the budget for another node. Thanks for any info. Jim

In Nutanix cluster, Life Cycle Manager (LCM) is used to track current software and firmware versions of all entities in a Nutanix cluster and is also used to perform certain software and firmware updates on this cluster. It consists of a framework and a set of modules for inventory and update. In order to fetch these modules, LCM connects to Nutanix Portal (download.nutanix.com) URL by default. However, in scenarios where the Prism Element (PE) cluster has no direct access to the internet, default Nutanix Portal URL option cannot be used for LCM since it depends on internet connectivity. In this case, prior to LCM 2.4.1.1 version, the only available option was to set up a local dark-site web server so that LCM can pull software/firmware bundles from this dark-site web server. However starting with LCM 2.4.1.1 version & above, LCM allows direct ingestion of certain software/firmware bundles using the 'Direct Upload' option in LCM. So, if you are at a dark site where the cluster does
