Deployment Success

Hey guys,I have uploaded some of ISO and disk image files including VirtIO to container via Prism Central and they all are marked as ACTIVE means that the upload process has completed successfully.But when I looked into the container to find the uploaded files via command line or WinSCP, all of them are being kept in container except for VirtIO iso file. Do you know how I can find it? Thanks and Regards. 

I have a user who is requesting that we change our VMWare Host Power Management Policy from Balanced to High Performance. Questions 1: Do Nutanix hosts support VMWare Power Management features?Question 2: We are migrating to all AHV early next year. Does Nutanix have a corresponding setting for VMWare Host Power Management Policies?

Hello,We plan to move some nutanix cluster to a new location and we already know that it will not be possible to keep the network vlan and IP setup for the installation.We found the document on how to change the CVM IP and you first advice is to keep the initial network if possible.So we should understood what are the argument pro and against regarding the IP reconfiguration process, can we have some performance issue?In some case we want to keep the data on the cluster and other don't take care of them. So what are the best choice to manage this different move.And if some of yours have already perform this kind of operation, could you share your feedback or advice on that.Thanks for your answers.Regards.David ALEXANDRE.

I have a Hyper-V VM that I want to migrate to our Nutanix AHV cluster.  This VM has a C Drive and 2 ISCSI mounted drives that are mounted within the VM through the Windows ISCSI Initiator.  Will Move migrate those 2 disks as well or do I need to plan to copy data after the migration has taken place?

Hi everyone, Is Nutanix Move 3.x is available for download in CE Edition ?

Sometimes, NCC (Nutanix Cluster Check) will alert for PSU down and a case is automatically created when a PSU down is detected.This can be a false positive alert or are transient errors (when relocating a node or some maintenance which requires a PSU down).However, a Power supply alert should never be taken lightly. One can always verify the physical status of Power supply by checking the LED indicators on the PSU unit itself, but in certain cases this may not be possible right away - due to the equipment location etc.  To ensure Power Supplies of a Block or Node are in optimal state, you can login to the physical host or execute a command from the CVM to check their status:From a AHV Host:[root@AHV-HOST~]# ipmitool sdr | grep -i psPS1 Status       | 0x01              | okPS2 Status       | 0x01              | okFrom a CVM on AHV (this will query all HOSTS in the cluster):nutanix@cvm$ hostssh "ipmitool sdr | grep -i ps"From a CVM on a ESXi Host:You can query all hosts PSU status:nutani

As we have a strict policy in our company to be always at the latest patches for all services, we are required to upgrade to latest version of VMware "ESXi 6.7 U3" which was released last month, we are already running 6.7 U2 now. we have already upgraded our vCenter to 6.7 U3 which we do not think it has any issues with Nutanix. But to upgrade ESXi itself we do not know about its compatibility, i know about the case of patching ESXi to a higher patch level than the Nutanix certified ones "which we are regularly doing", but for ESXi 6.7 U3 we are afraid of breaking something or being incompatible, and we do not know either if ESXi U's are considered as patches or different versions according to Nutanix.. I searched over Internet and this forum about anything related to 6.7 U3 compatibility but found nothing, at least if we have a road-map from Nutanix about planned compatible version we can wait till its release. Thanks

Nutanix reserves space on the SSD-tier of each CVM for its infrastructure. These files and directories are located in the /home folder that you see when you log in to a CVM. The size of the /home folder is capped at 40 GB so that the majority of the space on SSD is available for user data.Due to the limited size of the /home partition, it is possible for it to run low on free space and trigger Prism Alerts, NCC Health Check failures or warnings, or Pre-Upgrade Check failures. These guardrails exist to prevent /home from becoming completely full, as this causes data processing services like Stargate to become unresponsive. Clusters with multiple CVMs having 100% full /home partition will often result in downtime for user VMs.The Scavenger service running on each CVM is responsible for the automated clean-up of old logs in /home and improvements to its scope were made in AOS 5.5.9, 5.10.1, and later releases. For customers running earlier AOS releases, or in special circumstances, it may

HI Trying to get a definative answere to what I think should be a simple question. Can I map a iSCSI drive to a Virtual Server by attaching a iSCSI Storage array ( Server has a Drive on the nutanix cluster and a second drive mapped to the exsternal array ( NTFS partitions on the MD iSCSI array ( NO VM's running on the array ) just mapping this as a drive Would love to get a formal response from Nutanix if this causes issues within a cluster or will there only be issues with the specific VM's the mappings are assigned to ?

High-Availability(HA) is a life-saver feature which minimises downtime and can save the production environment. What exactly is HA in AHV?  AHV VM High Availability (HA) is a feature built to ensure VM availability in the event of a host or block outage. In the event of a host failure, the VMs previously running on that host will be restarted on other healthy nodes throughout the cluster.  Want to know more about AHV HA? Give the following KB article a read!4636   So, do we ever want to disable HA for few VMs? Yes, there could be situations and architecture constraints which might make us disable HA for a few critical VMs.The reason, you ask? (*voice of Yoda*) One possible situation could be licencing constraints of few application workloads which are tied to host CPU.   So what happens when you disable AHV HA for a particular VM?  In case of a node failure, the VM will not be migrated and started on another Node.    How can we achieve this?    Read more about disabling HA and Agent-V

Nutanix offers a monitoring & alerting utility, NCC - Nutanix Cluster check, which comes    pre-installed on every CVM.Nutanix Cluster Check is a powerful framework which includes several plugins to monitor & alert on different hardware and software components. It is installed on every CVM across a single cluster on all nodes.It comes with almost all Nutanix products, such as Prism Central, Files etc. NCC will include the relevant checks for these products, enabling Nutanix administrators to keep on top of any software, configuration issues. Following are some of the important Hardware (Physical Components) checks and alerting offered byNCC:a) Periodic Disk checksb) Periodic BIOS / BMC Firmware checks (Versions / Upgrades required)c) Boot Devices Monitoring (Sata DOM or M.2)d) SSD and HDD wear and tear checkse) BIOS, BMC checks to ensure all hardware components are current and stablef) Network Interface card checksg) IPMI / Out of band management interface checksh) Power Supply

We all know that the data never shrinks, only expands. As of AOS 5.0, hot expand of VM disks is supported. All you have to do is expand the volume group via Prism UI or CLI (either aCLI or nCLI - chose your preferred method) and then extend the disk in the disk manager within guest OS itself.aCLI:nutanix@cvm$ acli vg.disk_update <Volume Group name> <disk index> new_size=<size of disk>nCLI:nutanix@cvm$ ncli volume-group update-disk uuid=<Volume Group UUID> index=<disk index> size-mib=<Size of disk in MiB>For detailed explanation and caveats please refer to:KB-3638 Expand volume group disk size on Windows OSKB-5832 AHV | How to expand a Windows VM disk

Hi We currently use Files and I have created an SMB share. The share is setup to store disaster recovery information in the event a production failure. We use Data protection to replicate the share to another Nutanix cluster at another site.We want the ability to access this share in the event that our Active Directory isn’t available. I was looking for a location either in PE or PC where I could create local accounts and assign them as a user to this share but have been unable to find.Is this possible to do? Thanks 

Nutanix Move Can't migrate vm (SQL) in vmware it show  PCIE pass-through not support only 1 Server. Thank you for answer. 

Should you need to access container’s content directly, upload files to or download files from a container on AHV there is a simple guide with few things to remember: Do not delete any data from the container via WinSCP or any similar tool. Appropriate Prism or CVM command line workflows should be leveraged for doing the cleanup if needed. Deleting VM disk files directly from Nutanix container may affect Acropolis service, which can result in inability to manage user VMs.How to upload VM disk files from your workstation to Nutanix containerUsing WinSCP, connect to a CVM using SFTP protocol and port 2222 using Prism element credentials. Enable the option to show hidden files by going to Options > Preferences > Panels and then selecting the “Show hidden files”  option under the common settings. Select desired Nutanix container and upload file. How to download VM disk files from Nutanix container to your workstationPower off user VM, which disks will be exported, to avoid data corru

Let’s say you’re running a Nutanix cluster with ESXi as a hypervisor and noticing a lot of files in your datastore and different service crashing.You’re running a VDI workload and number of files in the datastore is exceeding 30,000 and the vpxa service is crashing. This can be critical for your infrastructure as vpxa is responsible for communication between the ESXi host and the VirtualCenter Server. Does Nutanix give you a warning before the file limit is reached?Absolutely yes!The NCC health check nfs_file_count_check verifies if an NFS datastore has more than 20,000 files.Want to run the check individually?  Login from any CVM and try running the following command: nutanix@cvm$ ncc health_checks hypervisor_checks nfs_file_count_check Nutanix recommends that the number of files in any datastore should be less than 20,000 if vpxa instability issues occur.Want to manually check the number of files in any datastore?Try running the following command from an ESXi host shellfind /vmfs/vol

The Simple Network Management Protocol (SNMP) enables administrators to monitor network-attached devices for conditions that warrant administrative attention. In the Nutanix SNMP implementation, information about entities in the cluster is collected and made available through the Nutanix MIB (NUTANIX-MIB.txt). The Nutanix enterprise tree is located at 1.3.6.1.4.1.41263.The Nutanix MIB is divided into the following sections:Cluster information. Status information about the cluster as a whole. Software version information. Version information about the software packages that comprise the Controller VM. Service status information. Information about the status of essential services on each Controller VM. Hypervisor information. Information about each hypervisor instance. Virtual machine information. Information about hosted virtual machines. Disk information. Status information about the disks in the cluster. Controller VM resource information. Indicate how much CPU and memory capacity is

If you are running AOS 5.10 or later, you may notice some user VM in Prism show two IP addresses. This could happen if the VM releases its older IP address and acquire a new one. You will see both old and new IP addresses in Prism for this VM, even if VM uses a temporary IP address like APIPA addresses (APIPA addresses fall into 169.254.1.0 - 169.254.254.255 range and use 255.255.0.0 netmask)This is by design and should nto last more than 10 minutes as we scan the arp cache every 10 minutes as we scan the ARP cache every 10 minutes to detect duplicate entries, and remove all entries corresponding to an IP address except for the most recent one. Tis has been explained in your nutanix portal kb 7652.

In modern IT Infrastructure, data is critical and having a copy of your data from where you can recover from has become an important pre-requisite for system design. To achieve this we use a technology known as Snapshot.So is it possible to even save your system running state while taking a snapshot in Nutanix environment?Absolutely YesIn Nutanix, we provide a technology known as application-consistent snapshot which can be selected when configuring Data Protection Domain.Want to know more about Data Protection with Prism elementGive the following article a readData Protection Guide So Nutanix have some guidelines with regards to Application consistent Snapshot?Absolutely yesNutanix recommends installing NGT on the VMs. Microsoft VSS service should be enabled. The workload running must be able to support to quiesce I/O operations. You must configure one consistency group for each VM. For the protection of VAAI clones with application consistency, each VAAI clone should be in its own pr
