Execute REST calls from a Linux machine rather than using the GUI (Prism)

Execute REST calls from a Linux machine rather than using the GUI (Prism) I would like to know if we can execute resp api query inside the curl command to create events such as VM create, delete, etc and get the response to the query I made through curl ? It's would be very helpful for us to help the client to automate the process of creating events/triggers through the Prism manually. Client has the Nutanix Prism and AHV in their network setup and creating these events manually.

Space reclaimation for LINUX servers - RHEL 6.7 * VMWare 6.5

Hi All, Hope you are doing well. I have question regarding the storage usage and space reclaimation in VMWare 6.5 with Nutanix clusters. This question is more into VMware instead of Nutanix, thought of checking here. Just to give a overview we have Nutanix nodes and we have got VMWare 6.x installed on the nodes, a single storage pool and multiple containers. I got a RHEL VM migrated from the old environment and it got 4 disks (10GB, 20 GB, 500GB & 5 GB), all the 4 disks are in the same DS and thin provisioned. No deduplication & compression enabled on those. Now when I access the VMware web console and look for the vmdk files by browsing the files in the DS, I can see a different capacity from the actual usage compared at the server level. When I see the same VM via PRISM and I cannot see the 4 disks assigned to it. It shows only 1 disk with some 160 MB used out of 20 GB and none other than that. Could you please help me to understand why its not showing the disks in the PRISM and why

Network switch best practice

I have 8 port 10BaseT 10g switch and I have four nodes with dual 10g and dual 1g. I also have a 1g switch with 50 ports. If I plug all 8 10g nic into the 10g switch I will not have an uplink port. However I still have thx 8 1g nic. So this leaves me with a couple options, and I was curios what best practice would be. A few options I have consider are: [list=1] [*]Only use one of the two 10g ports per node. [*]Configure AHV to use 10g for I/O only and 1g for connecting to the outside world. *not sure if this even doable* [/list]

Calm Project: Getting SYS_FAILURE everytime

Hi! I have a problem. When I try to create, delete or do a other action I always get the SYS_FAILURE but the Tasks goes through and work perfectly. After that I try to delete the action that was created but there I get again the SYS_FAILURE I work with VMware. There I cant find an error the VMs are created and deleted when I do the specific Action, so it has to be a Calm configuration error. Has anyone experienced this in some way? Thanks for your response! [img]https://d1qy7qyune0vt1.cloudfront.net/nutanix-us/attachment/ec0d7f2c-8046-4d79-9def-a6541d557ddc.png[/img]

New to Nutanix - pointers please...?

Hi All I am having my first foray into Nutanix using 3 x Dell XC servers and 2 x Dell X4012 switches (stacked), TOR switches are Dell N3024 stacked - I have come from a background of VMware using blades and SANs, so I a little confused on the process for setting up the external networking. What vlans etc do I need on the switches for the Nutanix management, vmotion and storage etc? Is there any best practice documents or has someone completed a similar task and documented the procedures? Any hints, tips or configs gratefully received. Thanks Eric

Do I need Prism Central?

Hi All I am new to Nutanix and coming from a VMware environment I confused. I have a 3 Dell XC Cluster and I access the whole thing by a cluste IP address which puts me in Prism - the Prism says I have not registered with Prism Central - If only have one cluster do I need Prism Central, what benefit does Central give me? Thanks Eric

XenServer to Nutanix AHV VM Migration ERROR [Boot Device not found]

Hi, I am trying to move a Windows Server 2012 R2 VM from Xenserver to AHV. With reference to this article: AHV | Migrating a Windows VM from XenServer to AHV everything is working great except when I am at the last step. When I turn on the VM in AHV, I am getting a boot device not found error and windows will not boot up. Windows will start with a windows icon throws the error and restarts, then goes into disk repair, reboots and same error and goes into the troubleshooting menu and when I am restart the VM in AHV it again and always goes into the boot disk inaccessible error. I made sure all the Xen components are already uninstalled from the vm and Nutanix VirtIO drivers are also installed. Tried with loading the image as scsi and IDE, but still going into the same error. Also tried booting up in safe mode, tried disk repair, etc. but no luck. Please help if someone has a solution. PS: I am migrating Windows Server 2012 R2 from XenServer to Nutanix AHV.

Remote site replication tuning

What options are available within nutanix to speed up replication to a remote site? The best i am able to get on a single stream is about 20MBps (160mbps) with an aggregate speed of about 60MBps (480mbps) spread out over several streams. However, we have a 10gbps link between sites, so i expected to get better throughput.

OVS Networking - Unable to bridge eth0-4 for other networks - Error

What's my goal? Right. I have 3 networks that cannot talk to each other for "reasons". Mostly because we have a test system that utilizes the same IP addresses (ORACLE Reasons) and we test & demo software in Prod, Demo, & Test networks. I just did a foundation on my system because I did an upgrade and the networking customization I had to do with OVS changed and wouldn't work anymore. Now that I'm working on a new install, I'm having trouble configuring the network and getting issues I didn't have before.

Citrix Applayering and Prism Central 5.5 issues

Specs: Citrix App Layering Version: 4.11 AOS: 5.5 Prism Central: 5.5 We are running into an issue when creating new app layers and platform layers after upgrading to 5.5. If I disconnect our clusters from prism central, the creation process works. The app layering appliance appears to have issues creating a packaging VM on the nutanix clusters as prism central is now managing the CRUD operations, as opposed to being managed strictly by the cluster. The error message we get in app layering is: The Nutanix server has encountered a failure processing the request: (500) Error: Internal Server Error, Details: Error occurred while creating Disk Image I'm not the most familiar with the low end nutanix platform, and where to search for logs, but it appears to be caused by the centralized image managed, or the centralized VM management function of prism. Has anyone else ran into this issue, or possibly know when this will be fixed? Citrix's response is lackluster (as usual), and they state that

Nested Shares on AFS

Hi, we have the need for nested shares on our fileserver. While this was easy on NetApp Filer it seems impossible with Nutanix AFS, or I am missing something. We are currently on latest GA release AFS 2.0.2. with AOS 5.0.2 on ESXi 6.0U2. Is this on the roadmap or even possible with AFS 2.1? Replacing Fileservers (Windows or NetApp, doesnt matter) could only be done with full feature set. best regards Steffen

VGLB and AOS 5.6

As the most of you probably know, with AOS 5.6, has been introduced the Volume Group with Load Balancing function, well known as VGLB As i know the 5.6 version is in short term support. Now i'm deploying a two Oracle 12c RAC clusters on 2 8000 6-nodes AOS-AHV clusters with AOS 5.5.3.1. It involves using volume group with multiple vdisk, network related configuration, Linux related tuning and so on... Of course, with 5.5.3.1 (so far the latest GA version in long term support), i've not the VGLS choice, every volume group's I/O is managed by a single CVM. By the other side, with AOS 5.6, i could distribute this load on every single CVM and every single node storage on the cluster. Of couse this heavily impact on the resiliency, the performance and the resources distribution. The questions are two and i need some suggestions. 1) could be better to upgrade to 5.6 even if it is in short term support? 2) is it possible to update "on the fly" the volumes's configuration with "vg.update load_b
