3 Site Availability Solution (Metro-Availability "Stretched Cluster" + DR Site)

Hello,   Is it possible to provide for a group of VMs a Metro-Availability (stretched cluster) solution using ESXi (since this feature for AHV isn’t available yet) to obtain 24x7 availability and downtime+disaster avoidance capabilities for certain services) and also provide for the VMs in the stretched cluster or a subset of those VMs async replication to a 3rd site (DR site)?   Understanding that the stretched containers are sync replicated at the container level, would that 3rd site async replication be based at the container or VM level?   Thanks!

Access denied trying to retrieve snapshot information

I’m receiving a 401 Unauthorized error when trying to access our cluster to retrieve snapstop information. I’m passing a valid VM UUID and have used credentials from one of our local user accounts which has both cluster and admin roles assigned. I can access most other methods of the API using these credentials, but not this one. What am I doing wrong?https://{prism_element_ip}:9440/api/nutanix/v2.0/flr/{vm_uuid}/snapshots

The clock is ticking!

This article's purpose is to shed some light on the rarely discussed, yet a crucial alert that you may come across on the cluster, that is, the HardwareClockFailure alert. Let us not confuse it with the system time. The system time is maintained by the OS (For example, Linux, Microsoft Windows etc.). The initial value of the system clock is typically retrieved from the real-time clock at power up or is set by the user. The hardware time is maintained by a real clock powered by a battery, which means it will persist a reboot.  The alert is generated when the hardware clock time differs from the system clock time. This check is scheduled to run every 10 minutes, by default.   To learn more about what causes a hardware clock to fail and how to resolve it, head over to this KB article: KB 4120 in the Nutanix Support Portal.

So is it Thin or Thick after all? VM disks provisioning.

This is one of the questions that do not exist on AHV. It is, however, a moderately important one for ESXi environment Nutanix or not. Why it is so and what does work best for ESXi on Nutanix – this is what I intend to unfold if you care to read. Without going into nitty-gritty details but still explaining the essential differences between the formats provisioning types for VM disks define how the storage space is allocated for the VM disk. The tree options ESXi provides are: Allocate space when required. No guarantees for the space available on the datastore for the data of the disk to grow to the extent of the disk size configured. This is a Thin Provisioned disk. Location of data on physical storage is written in fragments. Accessing these fragments when reading and allocating space for new data is what may create additional latency for sensitive applications such as databases, for example. Allocate storage section for the entire VM disk file contiguously. Guarantee space availab

Custom sizer hardware configurations supported?

Hello team, We used Nutanix sizer to configure a 3 node cluster, if hybrid mode is selected the smaller suggested option for cold data is a 4 X 2Tb SAS disks set when we choose 2 x 960Gb SSD for hot data. Is it possible to get support and buy a license if we configure the node with 2 x 2Tb disks? It's a small environment and we don't need all that extra space. Every hardware component is in the supported compatibility matrix of the vendor, just not sure Nutanix can fully support a custom configuration

Nutanix Guest tools

To enable VM management feature we can install NGT on user VM’s  To use the NGT feature, you must do the following: Enable the NGT feature for a VM in the Prism Element web console.  When you enable NGT for a VM, Prism Element prepares the VM so that NGT can be successfully installed and used in that VM.               Mount the NGT installer (ISO disk file) in a VM. Install NGT in a user VM. Few requirements we need to take care of: The following ports must be open between the Controller VMs and guest VMs on which NGT is installed: Controller VM: 2074. TCP port 2074 must be open in the Controller VM, so that user VMs can communicate with the Controller VM. User VM: TCP port 23578 if you want to use the VSS service.   For further details about NGT and its working please refer following links https://next.nutanix.com/how-it-works-22/nutanix-guest-tools-37346 https://portal.nutanix.com/page/documents/details?targetId=Web-Console-Guide-Prism-v55:m

Creating snapshots / recovery points

Hi! I’m trying to find a way to create automatically expiring snapshots via API. I know I can use v2 api to create normal snapshots, and with Playbooks I can create snaphots which have an expiry time. Is there a way to create recovery points (on-demand) or run playbooks via API? Thanks!

Nutanix AHV cluster - Configuration steps while replacing a NIC

When you replace the NIC cards in the Nutanix AHV cluster, it is possible that the new NIC card interfaces are recognised as additional interfaces and are numbered after the existing interfaces. So, for example, in the current AHV node you have 4 interfaces - eth0, eth1, eth2 and eth3 and you replace the NIC card and you see additional interfaces - eth0, eth1, eth2, eth3, eth4 and eth5.  Also, if your host was connected earlier on the replaced NIC card, you will lose the host connectivity. We now have the script in AOS 5.10.10 and AOS 5.15 to get the NIC interfaces re-numbered correctly. If you are running older versions or unable to run the script for any reason, you can use the annual method. Please check the Nutanix portal page here and KB3261 for the exact script and the manual method steps.

Isolating Possibly Infected VMs

Do you have a VM that you suspect may have been compromised or infected by malicious software (i.e. ransomware) and want to have a means to quickly remove it from your network (so as to not infect other entities)? Do you also want to be able to inspect and work on this VM from a “safe distance” using available forensic tools? Using Flow Microsegmenation, you can accomplish both of these objectives through the use of Quarantine Policies. When configuring Quarantine Policies, you can specify the “Quarantine Method” as either “Strict” or “Forensic”. The “Strict” option isolates the VM from all inbound/outbound traffic entirely. The “Forensic” option allows the limitation of inbound/outbound traffic to that which is specified from the “Add Forensic Tools” tab. For example, this could allow the infected VM to communicate only with another entity that maintains tools for further analysis of the VM. You can find more information regarding Quarantine Policies within the “QUARANTINE POLICY CO

Nutanix on Huawei

Hi,  We purchad Huawei servers end of last year (check compatibility matrix brought by Nutinix itself https://docplayer.net/136878906-Huawei-hardware-compatibility-list.html and due to Covid19, we were not able to install them until now.  Currently we have 4 servers with part numbers from compatibility matrix 2288Hv5-12 and 2x10G switches for interconnection. Each server has M.2 SSD drives for OS installation configured in RAID 1, while the rest of the disks (SSD of 1.92TB) are in JBOD mode, since that there are 2 RAID cards, one for M.2 and the other for SSD drives respectively. Virtual drive has status OK. During installation process, we receive error message that says the following: “INFO Performing firmware checks for platform Huawei 2288HV5-12 WARNING Some error occurred during firmware checks. This can be due to some unsupported hardware. Please report this to foundation team.”  Final error message is: Unable to find SSD in node. Please, help us resolve this issue in form o

You can modify it to show as many alerts as you like and choose how you want to resolve them. For details on how to count the total number of alerts and how to resolve them all in just one command, see KB 1402 in the Nutanix Support Portal.

Upgrade firmware on HPE DX by using Darksite LCM

Hi, I have built up a Darksite LCM running in my own local network and have Internet access to download necessary Darksite bundles for upgrading. In my testing evironment, the server works flawlessly with Dell XC cluster and Nutanix cluster as well but with DX cluster, it cannot provide any firmware update at this time though currently at least 1 node in our cluster is running on an old SPP version (2019.03.01). For our DX environment: Node1: 2020.03.0 SPP Node2: unverified? (LCM cannot detect the SPP version) Node3: 2019.03.01 SPP Does anyone have any idea on this case?
