Deployment Success

Hi community, I have some Qlogic 10G/25G NIC cards in my cluster which as I understand are not “supported” however seem to be detected correctly to some extent. Manage_ovs show-interfaces displays the output below which leads me to belive that the driver is loaded. However, currently those ports are connected to a 10G switch and so the speed and the operational status are not correctly working. Is there a way to set these by hand?  manage_ovs show_interfaces    name  mode  link speedenp5s0f0 25000 False  Noneenp5s0f1 25000 False  None    eth0  1000 False  None    eth1  1000 False  None    eth2  1000 False  None    eth3  1000 False  None    eth4  1000 False  None    eth5  1000 False  None    eth6  1000 False  None    eth7  1000  True  1000 When I add those cards to a vritual bridge I get the error message below. manage_ovs --bridge_name br1 --bond_na

Hi folks,Can I convert HC node to CO node? if yes, how?

How do I check hot and cold data by virtual machine? I'm going to migrate the virtual machines of the existing nodes to the node that I'm going to buy new ones. So, I'd like to check the hot and cold data of the virtual machines, respectively.

Good morning All   I have a bit of an NGT issue, the Prism Central alerts me to say some VMs need a NGT upgrade, when I go to upgrade them I see the message “NGT can only be upgraded on 0/1 VMs which have the available upgrade of NGT”   Review and confirm buttons are greyed out so I cannot continue - what does the message mean and what do I do to get it to work?   Many thanks   Eric

We have 3 nodes with 2x960GB SSD and 4x4TB HDD.We need to expand storage (and storage only as it is going to be used to store cold data - we do not need additional processing power or RAM)Question 1: We simply added two 12TB HDDs to each node. Now each node has 2x960GB SSD, 4x4TB HDDs, 2x12TB HDDs. Everything is working fine, but we were told that this is not recommended. What is the problem with this configurationQuestion 2: Assuming the configuration in Q1 is not recommended and we want to end up with each node having one type of HDDs. We were told that we can upgrade the existing 4TB HDDs with 12TB drives. What the right procedure would be:  a) Mark one 4TB drive for removal, remove it, insert 12TB drive in place of removed 4TB drive. Repeat 4 times for a node. Resulting configuration - 6x12TB HDDs per node  b) Add two more 12TB drives first, then mark for removal and remove four 4TB drives (one by one). Resulting configuration - 4x12TB HDDs per

Looking at the site below, I understand that ESXi 7.0 is supported. But I'm not sure if vCenter 7.0 is supported.https://portal.nutanix.com/page/documents/compatibility-matrixIs it a problem to use vCenter 7.0 ?Also, where can I find out which vCenter versions are supported?

I am trying to move a VM from EXSI to AHV. When I try the move I get the error “VMTools is not running.” any suggestions?

Hardware failures are a part of any datacenter lifecycle. The Nutanix architecture was designed with this inevitability in mind. A cluster can tolerate one or two failures (depending on the replication factor of the cluster or container) of a variety of hardware components while still running guest VMs and responding to commands through the management console. Many of these failures also trigger an alert through that same management console in order to give the administrator a chance to respond to the situation.Nutanix provides the ability to tolerate rack failures for extended data availability, in addition to drive, node, block, and network link failure.Block fault tolerance lets a Nutanix cluster make redundant copies of data and m

Failures are part of everything and Nutanix Clusters is not immune to it. But how we plan for failures determines the versatility of the product or a person for that matter!!Nutanix categorizes the type of failures into availability domains essentially based on type of failure. Nutanix provides the ability to tolerate rack failure for extended data availability, in addition to drive, node, block and network link failure. Node FailureA Nutanix Node comprises Physical host and a controller VM. Both these components can fail without any impact to the Nutanix cluster.CVM failureWhen a CVM fails, an a

Hello, I tried to change the Prism admin password today, but the admin account keep locked automatically. So every time I have to reset the admin account from a CVM, but it gets locked after 5 minutes.

HiI have 4 Nodes cluster with the detailed network belowVLAN1000 : IPMI Usage (192.168.255.x/24)VLAN20 : GuestVM & Internal Cluster Network (192.168.2.x/24)I was using eth3 and eth4 in bond br0-up in bridge br0 (vs0) And then i’m adding a new vlan (VLAN30 : 192.168.3.x/24) for separating GuestVM network from Internal ClusterI am using eth0 and eth1 in another bond (bond br1-up in bridge br1) connected to my switchport mode access VLAN30. The problem is, when i created VM using that network (vs1), my guest vm cant ping anywhere even the gateway of its subnet. But when i test my laptop that connected to the switchport mode access VLAN30, my laptop can ping the Gateway.Here i give the detail of my topology and uplinks configurationTopology

NVIDIA GPUs primarily have two modes of operation: Compute and Graphics.Compute Mode: the GPU operates within a configuration that is optimized for high-performance computing applications.Graphics Mode: the GPU is optimized for graphics processing and can subsequently be assigned into vGPU profiles for virtual machines (vGPU profiles cannot be used while in compute mode).Various NVIDIA GPUs are provided with default configurations for either of these modes and, sometimes, it is necessary to change the mode to better suit the corresponding workload of the host.In previous models of GPUs, it has been necessary to temp

We have numerous clusters and each have their own hardware platform (and in a couple of cases, we’ve even mixed hardware models within the same cluster). Our current Nutanix footprint;VENDOR         MODELS        NODE COUNTSuper Micro    NX-8155-G7    12Super Micro    NX-1175S-G6    7Super Micro    NX-3060-G7    6Dell                 XC630-10         14Super Micro    NX-8035-G7    12Super Micro    NX-8035-G6    36Is there a preferred or recommended solution for hardware monitoring and alerting?

Hi!I am wondering, if there is a quick way to restore from a failed ESXi upgrade.Imaging you have fired up a ONE-Klick-Upgrade of the ESXi image, and (as see with ESXi7.0U1GA) the hypervisor is not boot up again.At ESXi level i can backup config and restore config after a plane install. But what about CVM?Setting up the whole node with foundation is a nightmare, if the node is already installed in an customer environment, and can’t be discovered.The best way would be, that the foundation within a cluster could deploy a CVM to a plain ESXi and rebuild the cluster-node from the information stored in the cluster...

HI Team under Prism we’ve created a few VM’s (windows), one of VM is our File Server, current configuration is IDE disk 1TB, (60GB OS, 900GB shared folders). probably is better to create one virtual disk 60GB on OS and the second virtual disk as storage (1TB) or more.question is how to shrink current IDE disk from 1TB → 60GB, and if IDE should be change on SCSI disk, what Nutanix recommended?instruction to shrink disk IDE->SCSIthanks Dariusz

Nutanix Era is a suite of software which automates and simplifies database management, bringing one-click simplicity and invisible operations to database provisioning and lifecycle management (LCM). Starting with Copy Data Management (CDM) as its first offering, Nutanix Era enables database admins to provision, clone, refresh and restore their databases to any point in time. Through a rich, but simple to use, UI and CLI, they can restore to the latest application-consistent transactionEra enables you to easily provision database environments (either production or otherwise) on your Nutanix clusters. Also, you can only provision the database server VM that hosts a database, so that you can later create or clone databases on that database server.Some of the components include

Using the Nutanix CMDlets it turns out that out of the 7 protection domains in my cluster, one has only 1 Consistency Group assigned to it, which protects over 1200 files. (Almost 4000). How can I create a few CGs within a given PD so I don’t get the threshold alert in the future?

 A single-node cluster is configured like a regular (three-node or more) cluster in many ways, but here are some of the conditions. Nutanix offers the option of a single-node cluster for ROBO implementations and other situations that require a lower cost option and accept lowered resiliency protections. Single-node clusters are supported only on a selected set of hardware models. Refer the following article for details single-node-supported-hardwares Do not exceed a maximum of 1000 IOPS

From the Nutanix Bible: “when a Curator full scan runs, it will find eligible extent groups which are available to become encoded. Eligible extent groups must be "write-cold" meaning they haven't been written to for awhile”.I have 2 questions:if I have some data just written in the oplog, how long takes to copy those datas in the extent store, assuming that there is not any read of it?Once the data are in the extent store, how long it takes before the erasure coding is applied to the datas?
