FleX Driver Developer Kit Guide

OverviewFleX Driver Development KitDriver development overview.About this taskNutanix provides the FleX Driver Development Kit (DDK) to help developers build, inject, qualify, and distribute new drivers.Use the DDK to build a Linux kernel with one or more loadable kernel modules. The DDK builds a Linux kernel tar file that you can use as an input for Metis.In general, the driver development procedure is as follows:Procedure Prepare the compile environment. Prepare the source code to compile. The source can be an updated kernel source tree or one or more out-of-tree kernel module. Compile the kernel and modules to create the kernel tar file with the driver. Use the new kernel tar file as an input for Metis. Use Metis to qualify the new kernel and driver. Submit the driver source code (source rpm), qualification results, the procedure for building the driver, and release notes though your qualification ticket on the Elevate portal.

Shutting down a cluster

The instructions for shutting down a cluster are to use “sudo shutdown -P now” on the CVM’s in the cluster to shut each one down, but the command only works on the first CVM.   The command errors out the rest of the CVMs because they can’t reach the first CVM that was shut down.   Am I missing something?

Upgrading AOS 5.1.5 to 5.20.1.1

I need to upgrade an dark site cluster from AOS 5.1.5 to 5.20.1.1.   It looks like I need to upgrade from 5.1.5 to 5.5.9.5 to 5.10.11.1 to 5.15.6 to 5.20.1.1.   Will I need to upgrade the AHV matched to each version after I upgrade the AOS?

Foundation Bare metal build on Secure boot systems

I have a few systems to rebuild from baremetal. They are all secure boot enabled and to disable this I have to go onsite to change a jumper.Foundation dosen’t seem to be working which I am assuming the phoenix boot just gets skipped as its not uefi enabled. Is there a version or a process I can use to bare metal build these systems. I can easily install esxi manually if required.Just trying to avoid a trip into a covid zone to change a jumper if i can avoid it.

Objects Browser

 The Objects browser is a User Interface (UI) that allows the users to directly launch the object store instance in a web browser and perform bucket and object level operations. This eliminates the steps of logging into Prism Central and launching the Objects service. The administrators use Prism Central to manage the object stores. When an administrator creates an object store, a default bucket (object browser) gets created. The static website hosting capability is already enabled on this default bucket. The Objects Browser UI is hosted on this default bucket is created  The administrator can share the object store URL with the user to access the Objects Browser UI. The URL can be formed using the Objects Public IP addresshttp://objects-public-ipaddress/objectsbrowserYou can use http or https to access the web-browser Administrator workflow:The administrator needs to perform the following steps to grant access to the Objects Browser to a particular set.To grant access to Objects Brows

Where is the v3 API for migrating disks?

https://www.nutanix.dev/reference/prism_central/v3/api/vms/postvmsuuidmigratedisks/ describes an API to migrate disks as vms/{uuid}/migrate_disks.  But the API is not available in AOS 6.0.  I got the following response{     "message": "The requested URL was not found on the server. If you entered the URL manually please check your spelling and try again." } The swagger definition from the cluster does not contain the endpoint either even thought the definition “migrate_disk_input” is defined. The cluster has the following information:            "config": {                "software_map": {                    "NOS": {                        "status": "INSTALLED",                        "version": "6.0",                        "software_type": "NOS"                    }                   },  ...                 "build": {                    "commit_id": "e13b03b321a1559f5de846520509a20f93289b8d",                    "full_version": "el7.3-release-fraser-6.0-stable-e13b03b321a1559f5de84652

Configuring Network Switch Information

About this taskTo track and record networking statistics for a cluster, the cluster requires information about the first-hop network switches and the switch ports being used. Switch port discovery is supported with switches that are RFC 2674 compliant. Switch port discovery involves obtaining statistics from the Q-BRIDGE-MIB on the switch and then identifying the MAC address that corresponds to the host. Such discovery is currently best-effort, so it is possible that, at times, an interface might not be discovered.Before you beginBefore you configure network switch information in the Prism web console, configure the corresponding SNMP settings on the first-hop network switch.About this taskTo configure one or more network switches for statistics collection, do the following:Procedure Click the gear icon in the main menu and then select Network Switch in the Settings page.Note: Network switch configuration is supported only for AHV clusters.The Network Switch Configuration dialog box ap

Cisco Switch for small deployment - which one to use ?

Hello,I´m new in this forum. In fact I´m new in the Nutanix world. We currently have a traditional VMWARE cluster with traditional FC SAN Storage and Catalyst 3850 switches (7 servers).We are planning to replace it with a brand new solution based on NUTANIX (with 6 nodes or so) but using VMWARE as hypervisor. The question that arise are:We need to install 2 new “top of the rack” switches for NUTANIX connections. If using Cisco (and taking into account our proposed cluster size) which one could we use ? I mean, Catalyst 9300 are ok ? Or they have to be the more expensive Nexus ?  To reduce initial costs we are planning to keep the Cat 3850 to act as coreswitch and also because we need to conect other devices, but we need to ones for the new nodes. Our current VMWARE Servers have 2 x 10G connection for DATA/VEEAM BK and 2 x 1G for vSphere MGMT/vMotion. In order to cope with data traffic but also with “disk sinc” traffic, should we provide the new nodes with  4 x 10G (2 for DATA/veeam BK
