Deployment Success

Hello All, I have created this great powershell script that makes VM’s in AHV. It has been a journey let me tell you, but I made it through. The one thing I would like to add to this is creating a vm with UEFI boot option. I know this needs to be done at creation and I can create it in the acli with the following: acli vm.create UEFIVM2 uefi_boot=true However; is there a way to do this with powershell? I will look at finding a way to wrap the ssh command above but it sure would be nice if it was just a parameter on the                         new-ntnxvirtualmachine cmdletIs there a way I can create the vm with UEFI with powershell? Thanks,Scott

I got some question from my college, He asked me when in prism. we set smtp server configuration. and also we set about alert email. Which network nutanix use to smtp protocol telecomunication. I mean if I set configuration like this.host name: smtp.gmail.comport: 993security mode: SSLuser: cat@gmail.compassword: ****from email address: nutanix@gmail.com and after I setting alert email, and after that alert is come. which network nutanix use sending email? 

I have a couple of oddities going on, one is an ongoing and one was post latest PC2021. update.I was getting warnings that I was using the CVM default password so I chnaged it, it is supposed to replicate to the other CVMs but i get a health alert saying the remaining CVMs are still using the default password - any ideas why?And post PC update, i can log in using ssh but I can’t login to the web UI - I get the login screen , but after I enter username and password (not default) I get “server not available”  I have run health checks and idf checks and all seem to PASS - is there a bug in the latest PC Patch?  Just to note I can log into Prism Element with my name and password ok.Thanks in advance.

Nutanix recommends that you use the Prism Life Cycle Manager to perform firmware updates. However, firmware must be updated manually if: The component is located in a single-node cluster, OR The component is located in a multi-node cluster, but the hypervisor the cluster is running does not support LCM firmware updates.

Hi,I have a small cluster of 4 nodes. Disk space usage for /home in all CVMs are increasing fast. After some investigation it appears that the /data/logs folder is taking majority of space, more specifically health_server.log file which is taking about 181gb now. 18133488        health_server.log.20201224-1413011144624 sysstats Does the health_server.log file keep collecting indefinitely, there must be a limit to this log file? Thanks.Beg

Hello everybody, i would like to remove a switch from the Network view in Prism Element, which also is no longer configured under Settings => Network Switch. The cluster was moved to different network a couple of months ago. So far I was unable to remove this old network swith from the Network view in Prism Element and it’s also no longer visible using ‘ncli net list-switch’ in CVM command line. There is only the existing switch configured under Settings => Network Switch. We use AOS 5.15.4 LTS currently. If I select ‘Go to Switch details’ when selecting the old visible switch in ‘Network’, I get an error => Switch with id ‘...’ was not found ! Any idea how I can remove such a switch, which is no longer available? Regards,Didi7

We are migrating workloads from VMware (vSphere 6.5) to Nutanix AHV (AOS 5.15 LTS). With regards to VM templates, any advantage in creating new templates on AHV? Any gotchas if we migrate (as per procedure, prepare and use Nutanix Move) VM templates to AHV? Anyway, we will have to migrate most workloads, but was wondering about VM templates. We’re leaning towards erring on the side of caution and creating new templates (Linux/Windows) on AHV. However, I just wanted to know if anybody experienced issues with VMs built from migrated templates on AHV and any feedback.

Dear All,Can we use 1 G port for Hyper VM Traffic on Nutanix?

Is nutanix licensing tied to hardware?   use case for the question is a cold DR site.Scenario - VMs are backed up w 3rd party product and replicated to a DR site, e.g. SunGard,  and now its time to restore them for the DR test.If using Nutanix at this cold DR site, you have to build it from scratch before you can being restoring VMs to it, can the licensing used at the primary site be used for this?  or is the licensing restricted to the hardware it was installed on at the primary site?

We are facing performance issues with Nutanix volumes configured with Oracle RAC physical nodes. The latency is very high (25-30 ms).  Anyone has any suggestions on this.

I’m trying to move a VM (Ubuntu 18.04), when the cutover is done and i make a console connection the VM, at first the screen is blank, but after a few enters, i start getting the following signs on the console:Anyone has any ideas how to avoid this? I’ve tried installing NGT prior to moving the VM - no luck. On the initial GNU GRUB screen where I choose which OS to boot, everything is fine.

Hi all expert,I have question on vdisk and volume group on VMpros and cons using vdisk? pros and cons using volume group?Let have a discuss on which is better for daily operation and maintenance. 

I have a question regarding private networks.  I have an NFS share that resides in the 192.168.20.x network, however my Nutanix public (Internet access) network is in the 10.10.2.x.  I need to create a network where my VM can talk to the NFS server.  I’ve reviewed some YouTube videos but they’re not very helpful.  Any better documentation out there?

Been having oplog errors for nearly 5 months now. I have read through the article: NCC Health Check: oplog_episode_count_check and I have been able to get the vdisk_id. The problem is that it not connected to any VM.  I have looked through all the disks connected to all my VMs and none of them are this disk. Running vdisk ls does give me this information though:     Name                      : 00054ce8-d482-d9dc-135d-1866da8ea766::NFS:2:0:457    Container ID              : 00054ce8-d482-d9dc-135d-1866da8ea766::1062    Container Uuid            : 75138a04-e025-4510-a9d1-05e319573732    Max Capacity              : 4 TiB (4,398,046,511,104 bytes)    Reserved Capacity         : -    Read-only                 : false    NFS File Name             : counters-4    NFS Parent File Name (... :

UPGRADING SERVER FIRMWARENutanix recommends that you use the Service Pack for ProLiant® (SPP) ISO file for applying firmware updates. Perform this procedure on every host in the cluster, one host at a time. About this taskTo upgrade the firmware on a server, do the following:Procedure If the server is part of a Nutanix cluster, place the server in maintenance mode.Information about placing a server in maintenance mode is available in the host management section of the Acropolis Command-Line Interface (aCLI) documentation. See the Command Reference for the supported AOS version.

Can a Nutanix Storage node contain more secondary VM copies than what would fit into the existing capacity on the cluster nodes disk? and if yes, how does one bring the storage node down for maintenance?

I am using the newest version of X-ray (3.10.0) to connect to a vCenter (6.5U1d) to have some performance tests for my cluster. At the step 4 (Validation) of creating the target cluster, it failed to validate the cluster.Error: Target cannot be verified.After looking into the log, in the HTTP Response body, it contains the 500 Internal Server Error. Still cannot get what it means as everything seems fine and the connection from X-ray VM to cluster still has no problem at all.
