Chassis Intrusion Feature

When looking through the IPMI event logs, you may come across a “General Chassis instruction” message that is asserted. This is event created when the node needs to be opened to conduct a replacement and the top cover is opened as a result.The chassis intrusion feature makes it difficult for a potential intruder to reset the sensor without authorization. Therefore, there is no physical button to reset the sensor on the node. The user has to reset this sensor in the IPMI web GUI, which is authenticated using administrator credentials.To find more information about this feature and instructions to reset the sensor, look at KB 1362 on the Support Portal.

Getting Context-Specific Help From the Prism Web Console

In this Google-ready culture, many users will immediately turn to an internet search engine when seeking for information regarding a specific question or issue involving Prism. However, many users are unaware that Prism maintains an online help system which responds-to and changes depending upon which dashboard is currently being viewed within Prism.For example, a user may be interested in deploying a File Server and may have questions regarding this while reviewing the File Server dashboard within Prism. From that dashboard, simply clicking the global question mark icon from the top menu and selecting the “Help with this page” option will automatically open a new browser tab to the File Server Management section of the Prism Web Console Guide. What’s more, the specific version of the Prism Web Console Guide that is displayed corresponds to the current version of Prism from which it was launched.Further, some of the dialogue boxes within Prism also contain a question mark icon which wi

Move ESX nodes from 1 cluster to another

Hey all -We removed 2 nodes from 1 cluster and want to add them to another.  We disconnected from vCenter and then removed them from the cluster using PE.  When they were relocated to the new location, the vlan is the same and they could keep their same IP addresses, but the new cluster could not see them.  It sounds like the customer had configured Distributed switches on the old cluster.  Do I need to undo some of that networking to see the hosts?  Would bare metal foundation be a better option and put AHV on the nodes?  That is our next route, but I still think there is a problem with the network configured in ESX even for that.  Is there any documentation around undoing the vmware networking for bare metal?  With factory nodes, I would have just added them to the same vlan and assigned IPs using crashcart and then the cluster should have seen them.  Help!

Override Installer CVM boot disk size requirement

Hi,First time attempting to install Nutanix. I’m experienced with VMWare, but I wanted to try out Nutanix, mainly as I read it will allow me to create a single-node cluster, using locally attached NVMe disks without the overhead (headache) of vSAN (that doesn’t work as a single-node).Running through the installer, I see I have to specify an AHV (equivalent of ESX?) boot disk and CVM boot disk that requires a disk of at least 200GB. If I understand correctly, CVM is the equivalent of vCentre Server (VCSA).Firstly, can I install this CVM somewhere else?Secondly, I don’t have a separate disk of >=200GB that I want to waste on CVM. I have a 128GB SSD that I would have used for data, but the installer won’t let me and I can’t use it for CVM either because it’s too small. If I can’t farm off the CVM to another device, is there a way to override this limitation? Even fat old VCSA only uses 72GB across its 13 disks. What is in CVM! These are my disks. As you can see, to install CVM on its o

X-Ray 3.10.0 Fails To Work With NVMe Nodes

02/09/2021 Update: 3.10.1 has been released and contains the fix for this problemAn attempt to add a cluster with NVMe drives in the X-Ray 3.10.0 fails immediately.While checking the log on the X-Ray VM the following can be observed in the xray.log:ERROR Error occurred while performing final discovery - Invalid value for `type` (SSD-PCIe), must be one of ['HDD', 'SSD', 'Unknown'] That issue is specific to the version 3.10.0 of X-Ray and affects only the clusters with NVMe drives. It is a software bug that is going to be fixed in the upcoming release 3.10.1.The workaround is currently to use the earlier versions. X-Ray 3.8 is validated to work correctly.Earlier versions of X-Ray can be downloaded from the following page: https://portal.nutanix.com/page/downloads?product=xraySimply click on “Other versions” to see the previous versions.

Removing Individual VM Disks from Flash Mode

Flash Mode is a great feature ensuring that VM workloads remain within the flash (SSD) tier of storage. Once flash mode is enabled for a virtual machine, all of the disks associated with that VM (including any future created disks) automatically get added to the flash tier.However, sometimes having so many disks within the flash tier can cause performance degradation for other VMs that are not configured for flash mode (but could benefit from using the flash tier of storage) or can cause the available flash tier space to be consumed too quickly. Further, it is sometimes not desirable to have all of the disks associated with a virtual machine contained within the flash tier.Accordingly and, though not available as a Prism Web user-interface (UI) modifiable option, individual VM disks can be configured to not use the flash tier even while the VM itself is configured for Flash Mode. The procedure for removing individual VM disks from the flash tier involves using the Acropolis Command-Lin

Network visualization and network switch information

Network visualization Is one of those underrated but extremely useful features. Network visualization is a consolidated graphical representation of the network formed by the VMs and hosts in a Nutanix cluster and first-hop switches. Nutanix network visualization allows you to group VMs by power state or by parent hosts, group hosts by parent clusters or select a particular node from the cluster. Choose your layout based on the current needs.   In Nutanix network visualization, every entity is interactive. For example, when you click on a VM you can see detailed information about its vNICs such as MAC address, IP address, VLAN ID, live statistics.   Similarly, switch port will show information about MAC address, MTU size, live statistics.     To enable Network visualization a set of requirements must be met: Configure SNMP v3 or SNMP v2c on TOR switches Enable LLDP or CDP on the first-hop switches. Network connectivity over SNMP port between CVMs and switch management IP addres

diagnostic.py failed to run on ESXi 7

Hi I deploy a 3 nodes cluster with ESXi 7.0 as the hypervisor successfully on AOS 5.15.3.But when I run the diagnostic.py to check the  cluster performance. It always failed to boot the diagnostic VM. I tried 3 times and all is same. from the log, seems the CVM cannot reache the diagnostic VM when check the boot status.I login to vCenter and check that there is no IP address for this VM in the summary page. And I can login the diagnostic VM from the VM console, I can check the ip address which is 192.168.5.253, but I cannot ping 192.168.5.254 and 192.168.5.1. also cannot ping 192.168.5.253 from CVM.From this information, I think the CVM cannot reache the diagnostic VM and timeout, so the diagnostic.py will fail after timeout. Is there any idear for this test? I can run thie script successfully in ESXi 6.7.

So guys I’ve got a flexlm license server running Windows Server 2019 that I am trying to use Move to migrate into my AHV cluster.  I tried migrating it once and it blew up the license server since I guess it builds a unique machine ID using a disk and perhaps CPU ID. Any idea on how to clone this in Move so when it comes across FlexLM and other license daemons are none the wiser?
