Deployment Success

Hi allI use the v2 Prism Elements API to clone a VM from a Protection Domain Snapshot.It seems to work and the VM is created (cloned) correctly.However: The new VM always has the Prefix “Nutanix-Clone-”.The values i pass via vg_name_prefix and vm_name_prefix are simply ignored. In the Web UI (using the v1 API internally) it works fine.Please see the attached screenshots of the Web UI and the API call. Thanks in advance!

In Nutanix Hardware, the IPMI (BMC) keeps track of hardware-related events using the Event Log/System Management Feature. If there is a hardware event that needs to be dealt with, Prism will create an alert and send you an email if Alert Email Configuration is set up. However, there are still other events in IPMI that can be useful.For example, a power button assertion, a chassis intrusion, shutdown related events, or session audits (failed login attempts) will be logged by the IPMI events logs and can be forwarded via email using SMTP.If you may be interested in this functionality, check out KB 2581 to find more information on configuring SMTP in the Nutanix IPMI.

Team,I have a NUTANIX cluster running on the Dell Hardware with 11 Dell XC6320-6 model servers. I have spare Dell XC630-10 server and want to  check can i re purpose that server to the existing Cluster which is running with  Dell XC6320-6  hardware ?

Collector Portal is the cloud version of the Collector desktop version offering a lot more in terms of features and capabilities.Collector Portal is an online repository for storing collections, creating projects for viewing, analyzing the collected data, and eventually sizing the collected data in the SIzer. The portal also allows for collaboration/sharing of the data/analysis between stakeholders for more informed sizing. You can also revisit/track old sizings/collections and regenerate the analysis/graphs for the data at a later point in time. Collector Portal Navigation Login Open

I find that the simplest things in life are the most complicated. Snapshot is one of those things, I believe. It is something we, administrators, do not hesitate to use and yet, not many undersand what it is or how it works. Below are a few things out of many. What is a snapshot? A snapshot is a difference. When a snapshot is created its initial size is zero. That is because initially there is no change to capture. Original data is locked. It can be read but it can’t be altered. All the changes are written to the snapshot. That is why and how you can recover the data before the snapshot - because it is still there and is still intact. What is a VM snapshot for? It is a recovery point that is meant to be kept for a brief period of time as opposed to backups that can be stored for months, years or even decades. Why does a VM snapshot file grow in size?

Hello team, I hope that someone can explain to me why, looking to sizer’s recommandations about hybrid configuations, SSD/HDD ratio is not size dependent but form factor dependent. Basically if you select 2 SSD and 3.5”HDD then a minimum 1:1 ratio is possible (SSDx2 + HDDx2) but if you have have SSDx2 and 2.5” HDD then the minimum ratio is 1:2 (SSDx2 + HDDx4). Is it because 3.5” HDD SAS or SATA are usually faster than 2.5”? It’s not about size or hardware vendor, recommandations seems to changes according to the disks form factor only

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!

Hi all, I have almost 200 Virtual machine in my AHV environment . Is there anyway to summary operating system in each virtual machine, Does it have any tool like rvtool in vmware ?

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

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 reso

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

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

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!  

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

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 “
