How to Run Execuatble Script from Desktop

Hi. I am fairly new to scripting especially with Nutanix. I can do Powershell scripting just fine but making the conversion to shell scripts has my brain in a knot. I have some acli commands to create a new vm, create a new Disk and a new NIC but I was unsure how to run them as an executable from my Windows desktop. Our cluster is Nutanix AHV. So I run this from a command line to open putty and connect. It works fine without the script. putty.exe -ssh admin@xxx.xxx.xxx.xxx -pw ****** -m "C:\newVM.sh" The script is: acli; #creates a clone of Server2016 #vm.clone aTest clone_from_vm="Server2016RefImage" memory=8G num_cores_per_vcpu=2 num_vcpus=2; #creates a D drive # vm.disk_create aTest bus=scsi create_size=200G index=1 container="Container-1"; #Add a NIC #vm.nic_create aTest connected=true network="Vlan6"; Each line will run fine if I run it in putty but I am not sure if I am stringing the commands together correctly. If I try to execute the script it opens the putty session the

Nutanix Calm APIs

We are happy to finally say the Nutanix Calm API is live! This includes the release of the Nutanix Calm API documentation on [url=https://nutanix.dev/]Nutanix.dev[/url], our Developer Portal. The possibilities that are now available along with this announcement are huge for us. It means we can do things like the following in code: [list] [*]Integrate the control of Calm blueprints into external scripts or applications [*]Use conditionals to control when a blueprint gets launched [*]Use conditionals to control which blueprint gets launched [*]Run applications actions on demand by calling the appropriate API [/list] It’s also true that, while APIs as an overall “thing” are definitely nothing new, the ability to automate the automation platform is a critical step in controlling infrastructure. Check out the blog :point_right: [url=https://www.nutanix.dev/2019/09/06/automate-everything-nutanix-calm-api-docs-are-live/]Automate Everything: Nutanix Calm API Docs Are Live![/url] to learn mor

How to get VM to Storage Container relation using REST APIs?

Dear Friends, I am trying to find out VMs to Storage Container relations using Nutanix REST APIs but not able to get. I have tried both V2.0 and V3 APIs. In 'vms/list' v3 API, we do get "disk_list" for each VM but I do not see these vDisks in 'vdisk' or virtual_disks APIs (v2). Also there is no reference to Storage_Containers in 'vms/list' output so it is difficult for me to find the correlation. Please help.

Fibre Channel connectivity to old SAN

Can you use a FC card in one node of a Nutanix cluster to do a storage Vmotion / migration to the New esxi Hosts in the cluster ? FC card will present the current VMFS partition to the new esxi host running in the cluster .Then storage vmotion the vm's across to the new storage( NFS partition in the nutanix cluster ) Is this possible ? Prefered option as NFS would only be on a 1 gig network and we need to do this quickly Any input will be appreciated ?

Metro Availability (Standby Site Maintenance steps)

Hello, I will need to power off a "Metro Standby Site", which has VMs running on it. I would like to manually migrate those VMs to the primary (active) site and Shut down / Power Off the nodes in the Standby site approx. 24-36 hours. All VMs need to be running on the active side and no VMs are to be restarted (RTO + RPO =0). The steps I propose to take to achieve the goal are as follows: I have included as much environment info as possible. Any insight or corrections to this process are welcome.

Latest Powershell CmdLets for 5.11

There appears to be an issue with the latest Powershell Cmdlets for Version 5.11 that reports itself as Version 5.1.1 (not 5.11) so there is a mismatch. This will bring up a Warning dialogue box asking you if you want to continue with this mismatch (Cluster Version 5.11 and CmdLets Version 5.1.1). This can affect any Powershell Automation Scripts you have running that will be waiting for user intervention! You can change the Nutanix Connection method to Force the Connection using the following syntax: Connect-NTNXCluster -Server "Your server here" -UserName "Your user" -Password "Your password" -AcceptInvalidSSLCerts [b]-ForcedConnection[/b] [b]Note: It is the ForcedConnection that enables the bypass of the mismatch for your scripts.[/b] Hopefully they will update the Version with the next iteration of the Cmdlets without the apparent typo of 5.1.1 instead of 5.11. Please feel free to "Like" to mark as "Best Answer" Kind Regards Andy [user=95361]andymlloyd[/user]

Get Only AHV VMs

Using PowerShell and AOS 5.11 connecting to Prism Central of mixed hypervisor environment (VMware and AHV), is there a quick way to return just the AHV VM's? I see there are some search string, filter criteria, etc.. options for Get-NTNXVM Right now, there are 1600 VMs and the ones I am looking for are AHV. I can retrieve the whole list from Prism Central but I wondered if I could have it only send a filtered list. $VMList = Get-NTNXVM | Where { $_.acropolisVm -eq "True" } but that reads all 1600 VMs from Prism Central... Thanks!

CloudFoundry on Nutanix

Good day I have a requirement to POC CloudFoundry platform(cf push). I have tried project-eirini running on Karbon k8s cluster, it works, kind of, BUT it is still on alpha . So it can't use it on Production. I researched a bit further to see if PCF(Pivotal CloudFoundy) can be installed on Nutanix and found there is no support for vanilla PCF on Nutanix. And the journey led me to this > [url=https://github.com/nutanix/Cloud-Foundry-CPI-for-Nutanix-AHV]https://github.com/nutanix/Cloud-Foundry-CPI-for-Nutanix-AHV[/url] Creating a CPI for CF on Nutanix. I need to know if this is worthy before I can invest time implementing. Has anyone implemented it? Is it production ready? (seeing it is part of nutanix GH repo) Thanks in advanced

Required ports for admin access and tools

Not sure why but there appears to be an absence of documentation pertaining to required ports that might need to be opened in a firewall to access the CVMs. Perhaps Nutanix thinks that organizations aren't going to firewall off the cluster to protect access from malicious users. If I'm wrong why don't I see a list of ports that are needed to access the CVMs rather than KB articles showing what outgoing ports are needed in a perimeter firewall? In order to properly protect a cluster the CVMs should sit behind a firewall, which in my architecture this will be the case before we go live with anything. In order for admins to access the CVMs through a firewall TCP 22 is needed for SSH, and 80 and 9440 are needed for accessing the web console. Is this is? or are there more ports that would need to be opened up for the various types of admin interactions? [list] [*]how about running cli tools against the cluster? [*]how about downloading support files? [/list] and I'm sure

Pulse: PE or PC?

Our CVMs are locked down tight, I have no intention of allowing any internet access to PE, all support actions must be done through a webex session where our admin grants control to the support tech. but I have PC set up for NAT so it can communicate outside our private network. my question is, will pulse work strictly through PC or does PE need to be set up for it? Everything i see documented is about PE talking to insights.nutanix.com.

A question about NearSync DR

Hi, My customer is considering leveraging NearSyncDR for their production clusters. Looks like I have to explain to them how NearSync should be configured and how it works to match their needs for future plan. As it matters, I have dived around Nutanix portal for some documents related to this technology but nothing explains clearly why it should run by its behavior in the example below: In the case I configured a schedule that repeats 1 min and retention policy of local cluster for 5 days, NearSync will work as that it will: [list] [*]Create a snapshot per minute and retain it for 15 minutes. [*]Create hourly snapshots and retain for 6 hours. [*]Create daily snapshots and retain for 5 days. [/list]So the question is if a snapshot A was created and deleted in 15 mins later, in the case user wanted to use this snapshot A to recover his file, how did he do? Is snapshot retaining time able to be changed by any command?

VM capacity and prism capacity are different

Hi, I got a question during the test. Window VMs(C: drive) , linux VMs(df -h) capacity different those capacity in the prism(VM-table). Not all VMs are like this, only a few are like this. These VMs erased a lot of data and got a lot of capacity. The Curator has since been executed, but the capacity has not decreased inf prism-vm-table. Why can't Prism return a VM's erased data capacity value? How do I get Prism to read this capacity?
