How It works

I have tried to write [] and other 3rd level keys in my Linux machine, but I am unable when connected through “Launch Console” in Nutanix.Workaround such as shift+ctrl+u (and then some code for the wanted key) does not work either.Is this a Nutanix “thing”, and if so, is there a fix or is there a workaround?

Remote diagnostic service is an on-demand log collection from Insights which leverages Pulse workflow, which is used to diagnose a specific issue which can be related to specific service, unlike pulse which provides a high-level log collection service. The remote diagnostics allows Nutanix support to collect a set of logs for troubleshooting a specific issue and it contains: Services related logs Custom gflags Activity traces for Nutanix services  Hypervisor logs and configuration  System statistics NCC health check reports   Workflow When Nutanix Systems Reliability Engineers needs some diagnostics data to be collected they go through the following workflow:   The Remote diagnostic is enabled by default with Pulse and Remote Diagnostics can be disabled later by having the Pulse service still enabled which is required for proactive monitoring of the cluster. Only authenticated and authorized users from support, sales and customer success can use the Nutanix Remote Diagnost

[root@linuxvm ~]# cat /proc/sys/kernel/sysrq16Default value is 16 which stands for "enable sync command". Modify the value of "sysrq" from "16" to "1". "1" means "Enable all functions in sysrq We can set this value to be persistent or non-persistent depending on situationNon persistent [root@linuxvm ~]# echo "1" > /proc/sys/kernel/sysrqPermanent - Reboot will be required to apply the change[root@linuxvm ~]# echo "kernel.sysrq =1" >> /etc/sysctl.d/99-sysctl.confCheck “sysrq” value again[root@linuxvm ~]# cat /proc/sys/kernel/sysrq Find AHV host in which linux VM is running nutanix@cvm:~$ acli vm.get <VM name> | grep host_namehost_name: "X.X.X.X" CVM to check the UUID of Linux Guest VM from any CVM nutanix@cvm:~$ acli vm.list | grep <VM name>linuxvm     66551923-eb86-4c69-933b-ecf15ec5f59c run below command to find out the domain ID of the Linux Guest

We have plan is to add e.g 10 new HPE Proliant DX380 12LFF server with the latest AOS, eg 5.17.1 into the existing cluster. Then remove 10 existing nodes and reimage and add it back. Can 5.10.5 coexisting with 5.17.1 in the same cluster? Thanks 

I'd like to just confirm, is there any Nutanix web page that lists the supported browsers?The support page below that I bookmark is already deleted.https://portal.nutanix.com/#/page/docs/details?targetId=Portal-Help:sup-browsers-requirements-sp-r.htmlSo I searched similar page in Support portal, but I couldn't find.I know the browser requirements is not necessary information for many people nowadays. However that page is useful for us, so I want to refer substitute one if exist.

Are you still wondering about the following questions?To Which Version of AOS should I upgrade to from my current version? Will it be 1-Click Upgrade or not? What are the EOL versions for AOS, Nutanix Files or Prism Central? What is my software compatibility?Answer to above queries and many other queries is one single Link i.e. Upgrade PathsHere are some snapshots from Tools:Image 1 Image 2Image 3 

Nutanix appliances support monitoring via SNMP. Only SNMP v2c and v3 versions are supported. SNMP v2c is supported starting with AOS 5.5. In addition, SNMP v2c with Nutanix does not support SNMP GET operations.The MD5 authentication is no longer supported in AOS 4.1 and later. SNMP can be set up using the Prism Web Console or from the nCLI. Setting up SNMP through nCLI Run the following command on any CVM (Controller VM) to add an SNMP user (encapsulate the keys in single and not double quotes). nutanix@cvm$ ncli snmp add-user username=SNMPUser auth-type=sha auth-key='SHAAuthKeyExample' priv-type=AES priv-key='AESPrivKeyExample'    User Name                 : SNMPUser    Auth Key                  : SHAAuthKeyExample    Auth Type                 : sha    Priv Key                  : AESPrivKeyExample    Priv Type                 : AES Privacy protocol settings are optional. You can create the user only with the authentication protocol: nutanix@cvm$ nc

This article provides quick links required for troubleshooting the alert – “Invalid Network Mapping Specified” for your Nutanix cluster. This alert can be generated if either the source or destination network configuration is not present in network mapping specified in the remote site, or the networks specified in the network mapping do not exist. To learn more about how to resolve this alert, check KB-10243.To learn how to configure a remote site, check this guide. For more information on Network Mapping, refer to this guide. 

Hello, Regarding to this question https://next.nutanix.com/how-it-works-22/disk-fault-tollerance-8822, What will happen to VMs in a cluster with RF2 when 1 drive failed on 2 different hosts? Will be any data loss or no? Will VMs reboot?Thanks!

If I update update firmwares or softwares via LCM, is LCM update out-of-band? Or in-band? I can’t find any information in TN-2122 (Life Cycle Manager).

Hello Guys, We´re currently trying to install a Big IP LTM image on Nutanix using acropolis however it´s not working... it seems we´re missing something. We´ve found a link in regards of this topic but we are receiving a message infoming we have no access to it. Does anyone know how we should proceed in order to install a F5 VE on Nutanix using acropolis? https://next.nutanix.com/archive-44/how-to-install-f5-big-ip-on-nutanix-ahv-8062# (not authorized to access) Thanks in advance!

I posted this earlier in the wrong forum. (Sorry about that. I’m a newb.) I am reposing here. I cannot seem to find the the performance stats in the v3 API that are available by default in the v2 get APIs for vms, clusters, hosts, etc.? Are the performance stats available in v3? If so does anyone know the endpoints. I’ve searched but cannot find them. I suspect v2 is going to be supported for quite a while so I can just use v2 but didn’t what to rule out v3 until I had a good reason to.

 Hello. I have a question about the RF2 function.Currently, it is composed of 4 nodes and RF2 as a cluster.As far as I know, RF2 has 1 node fail.If so, shouldn't the Data Resiliency Status drop to Fail?However, although one node has failed, the Data Resiliency Status is still OK.In fact, the CPU, Memory, and Storage usage in the current cluster is low.Currently only 3 nodes are active CPU is 20% Memory is 40% Storage is 18.5%.Why is the Data Resiliency Status Ok?Is there any problem with the service even if one more node is currently turned off?Or will the cluster die if 1 more Node dies?If you don't die, I want to know why.

Hi.  Prism -> Data Protection -> EventGroups of Async DR run backups only once every Dawn.However, if check the event, I will see several messages per group.If there is a ‘Search’ group, several messages are generated for the 'Search' snapshot in the event.Each has a different time.(AM and PM). How can you explain this process? Thank you.

Storage ContainersA storage container is a subset of available storage within a storage pool (see Creating a Storage Container). Storage containers are created within a storage pool to hold virtual disks (vDisks) used by virtual machines.CompressionYou can enable compression on a storage container. Compression can save physical storage space and improve I/O bandwidth and memory usage—which may have a positive impact on overall system performance.Inline compression will compress sequential streams of data or large I/O sizes (>64K) when written to the Extent Store (SSD + HDD).Offline compression will initially write the data as normal (in an un-compressed state) and then leverage the Curator framework to compress the data cluster wide. Below diagram explains how inline compression interacts with the DSF write I/O path:DeduplicationDeduplication reduces space usage by consolidating duplicate data blocks on Nutanix storage. You can enable either cache deduplication only or both cache an

Nutanix platforms use a baseboard management controller (BMC) and basic input/output system (BIOS) to control the motherboard.The Nutanix BIOS contains optimized power management settings by default. Please do not change Power Management Configuration settings in the BIOS. Nutanix does not support custom power management configurations, and changing the power management settings in the BIOS can cause unpredictable behavior.Procedures updating the BMC and BIOS:1. Upgrade through LCM2. Manual UpgradeBMC: Nutanix BMC Manual Upgrade GuideBIOS: Nutanix BIOS Manual Upgrade GuideNote: Always upgrade BMC before BIOSRelease Notes: G6 And G7 Platforms

AHV hosts in cluster running AOS 5.18 or newer may become non-schedulable if bridge configuration across cluster nodes is not consistent. What is a non-schedulable node?A non-schedulable node is used to increase data storage on your Nutanix cluster and does not run any guest VMs on that node.To check if this situation exists on your cluster and to fix the issue, check KB-10217.
