Automated listing IPMI, CVM and Hypervisor IPs in CLI

 Anecdote by @Kiran Surya  Nutanix users and administrator are often required to access the CVMs, Hypervisors and IPMIs through their IP addresses.  The most commonly used method to look at the IP addresses of these three entities is through Prism Element, and going through the Hardware tabs.  However, looking through the GUI can be time consuming since you are required to click on every Host to view the IP address details of all three components.  It’s all the more cumbersome if you have a huge infrastructure, like say 24 Hosts.  It would be ideal if there is an easier process to list all these pieces of vital information.   I happen to use the following combination of characters to list all these three pieces of data, and needless to say the customers are delighted when they see me run this command:  nutanix@NTNX-7B43JB2-A-CVM:10.171.154.127:~$ nutanix@NTNX-7B43JB2-A-CVM:10.171.154.127:~$ echo; set `ncli host list | grep Address | sed 's/^.*: //'`;echo -e "    IPMI\t    CVM\t\tHy

Resource requirements for Prism Central

This article’s purpose is to provide assistance in determining the right amount of resources required to enable various services on Prism Central.Currently, there are multiple services available such as CALM, Karbon, Objects, Files, etc. Each of these services adds their own resource requirements to Prism Central hence, increasing the need for more resources for Prism Central in order to function properly. If enough resources are not configured, you might encounter the alert “Configured resource for the Prism Central VM is inadequate”. The NCC health check pc_vm_resource_resize_check verifies that the configured amount of memory and vCPU resources of the Prism Central VM is adequate. This check is introduced in NCC release version 3.10.0 and applies to Prism Central VMs (version 5.17.1 or higher) only (inapplicable to Controller VMs (CVMs) of Prism Elements clusters).Please refer to KB-8932 for more details.To learn more about the various services available and to determine the Prism C

Nutanix Prism Element, Central and Pro Overview Video

Hello, this is Marc Malotke, your Nutanix SE. Today, I would like to provide you an overview of Prism Element, Prism Central, and Prism Pro. First, it is important to understand that our Nutanix solution is made up of two distinct pieces, Prism, and Acropolis. Since we will be diving into Prism today, I want to spend a moment talking about Acropolis. Acropolis is our operating system that includes the distributed storage fabric, the application mobility fabric, and let's not forget our Acropolis hypervisor that we like to call AHV. [video]https://youtu.be/tGzcUL6RN6s[/video] So what is Prism? Here's my definition. The single pane of glass to manage your data center that provides one-click infrastructure management, one-click operational insights, and one-click planning. This is very important because if you think about the way you go about your day in the data center, you are actually in and out of multiple tools and GUIs to not only manage your data center parts and pieces, but yo

Recover a VM from the snapshot

Did you know you can restore a deleted VM from a leftover snapshot? If a virtual machine (VM) was accidentally deleted or migrated to a remote site provided the snapshot remains the VM can be recovered. When deleting a VM using Prism an option ‘Delete all snapshots’ is available. When the option is not selected the snapshots remain in the container and become orphaned. Similarly, when a VM is migrated to a remote site an is disassociated with the protection domain the snapshot remains. The recovery operation relies on a clone operation in aCLI. Clone a VM from a snapshot is essentially what happens when recovering the VM.   Follow KB-6194 Cloning from AHV Orphaned Snapshots for a simple set of instructions on the process. Prism Web Guide contains more information on Disaster Recovery operations.

Prsim troubleshooting cheat sheet

I thought I’d put together a set of sources to help with troubleshooting some of the popular issues with the Prism.If you ever lock yourself out of Prism account do not fret. Local admin account can be unlocked by logging into a CVM with nutanix user and resetting the password for the admin user.KB-8130 Prism Admin Account Locked With "Account locked due to too many failed attempts." If you ever need to find a Prsim Leader node as part of any troubleshooting:KB-1841 Checking which node is the Prism Leader. To verfify connectivity status between Prism Central and Prism Element use NCC check cluster_connectivity statusKB-3379 NCC Health Check: cluster_connectivity_status. For troubleshootimg PE to PC connectivity follow KB-6970 PE-PC Connection Failure alerts.Expand the list in the comments, help the community!

Change IP address of Prism Central 5.16.2

I need to move the PC VM to a different cluster and want to change the IP address of PC. I cannot find a description for version 5.16, only a very old one for version 4 that does not work. I also tried the instructions from https://portal.nutanix.com/page/documents/details/?targetId=Advanced-Setup-Guide-AOS-v5_16:ipc-cvm-ip-address-reconfigure-t.html but it does also not work. After reboot VM ip address is still the old one. Is there a description how to do it with PC 5.16?

Using Lets Encrypt Certs on Prism Central & Prism Element

I am looking to replace my SSL certificates on my Prism Central and Prism Element deployments with Lets Encrypt wildcard certificates. I can request the wildcard certificates easily enough sudo certbot -d example.com -d *.example.com --manual --preferred-challenges dns-01 --server https://acme-v02.api.letsencrypt.org/directory certonly I get generated three files: privkey = /etc/letsencrypt/live/example.com/privkey.pem chain = /etc/letsencrypt/live/example.com/chain.pem fullchain = /etc/letsencrypt/live/example.com/fullchain.pem Can anyone advise what openssl commands I can use to convert these .pem files to the required format needed for Prism Central/Prism Element? I have attempted multiple commands from https://www.sslsupportdesk.com/openssl-commands/ but I can't seem to find the exact one.

How to remove orphaned snapshot

As a starting point of all or nearly all troubleshooting Nutanix recommends running Nutanix Cluster Checks (NCC). NCC identifies any risks or misses in the cluster configuration, hardware state, software components, networking and more. Checking for presence of orphan VM snapshots is part of NCC which, I think is quite convenient as chasing orphaned snapshots can be a hassle. Should you already know that there is a snapshot that is orphaned it can be removed with a single aCLI command. To be on the safe side always validate that the VM no longer exist. Otherwise, solution section of KB-3752 NCC Health Check: orphan_vm_snapshot_check lists all the steps necessary.   More on the subject: NCC - why it is important to upgrade it

We have different clients and we want to give visibility them only to manage their VMs. When a client access to prism console, he only will be able to check his VMs and resources, create new machine on his side...not resources and VMs from the B client for example. Is this possible using the last version (5.10.2)? We have seen on last version Nutanix has launched Self Service Portal? Could it be helpful to achieve this requirement? Thanks in advance. Regards,

UEFI on VMs FAQ

What are the advantages to having UEFI set on a VM?  UEFI firmware is a successor to legacy BIOS firmware that supports larger hard drives, faster boot time and provides more security features.  Creation and starting VMs with UEFI firmware provide the following advantages. Boot faster Avoid legacy option ROM address constraints Include robust reliability and fault management Use UEFI drivers   Are there disadvantages of enabling UEFI on a VM? Not per se however not all guest operating systems are compatible. For AHV Please always check compatibility matrix AHV Administration Guide: Compatibility Matrix for UEFI Supported VMs. Also keep in mind that cluster conversion and cross-cluster migrations might be affected by enabled UEFI: Ensure that you do not have VMs with UEFI boot firmware enabled when converting from ESXi to AHV. See Prism Web Console Guide v.5.16: In-Place Hypervisor Conversion. VMs with UEFI boot configuration do not boot after migration when migrating bet

Prism Central: VM Backup / move to another AHV cluster

Hi folks! Does anybody backup Prism Central VMs in a Protection Domain? I was just thinking about that, since I need to move all VMs from one AHV cluster to another. That's because I need to reinstall the cluster with ESXi for compatibility with some VMs. The only way I found out is to create Protection Domains and replicate the VMs to the new cluster. So does this work with PC VMs also? Regards, Andy

VM creation date and time - quick tip

Did you know you can determine when a VM was created? All you need is a Prism Central instance.In PC UI go to Virtual Infrastructure –> VMs –> List –> in Focus dropdown choose +Add Custom  and search  for “Created Timestamp”.You can also find the time stamp from PC CLI using nuclei.For details refer to KB-9045 How to find a VM creation date and time in Prism Central.  Always remember to configure adblocking plugin (if you are using one) in the Web browser to exclude Prism from checks.

Distribute template VM's as qcow2 images globally using Prism Central image management

We normally keep a handful of template VM’s with different type of OS that are updated and “ready to go” and use these for global automation when deploying new machines. I would like a way to deploy these templates as qcow2 images globally using the Prism Central image management. After a template VM are updated, I would like to automate them beeing converted to qcow2 images (already got this working with “qemu-img convert” command) and then import the qcow2 image to the Image repository in Prism Central to be distributed to all sites. The last step I have not managed to figure out how to do. Obviously I need some kind of API or CLI to automate this but all I find is how to do this using the GUI in PC. Did I miss something?

How to rename CVM Container?

Is there a way to rename the CVM Container without rebuilding the container? The vendor who recently re-installed the Nutanix Block didn't follow the directions and named the container incorrectly. The container has 4 Virtual Servers running on them and I would like to preserve these systems without the need of rebuilding them. Could I place each VM in the Local NTNX-local-ds (SSD) datestore since the 50GB available is larger than each VM? Then Destroy the Container and Recreate it? Thanks,David

Analysis tab data export question

Hello everyone, I have a question concerning the analysis tab on the Prism Element UI. To get started i will shortly explain what our current situation is: Last year we sold some Nutanix boxes to a customer. In this contract we also included monitor/management services. As an agreement, every month we schedule a meeting with our customer where we evaluate performance of the nutanix clusters. There are 3 main fields we focus on during the meeting; Cluster host usage, storage performance and storage usage. (See picture below) [img]https://d1qy7qyune0vt1.cloudfront.net/nutanix-us/attachment/2455iA44A83E08CA1AFD3.png[/img] In this report we include all the data we extracted from the analysis tab on Prism Element. We import this data into excel and pour that data into graphs. (See picture below).
