Nutanix Snapshots

Please Help: As per this video, when the new data is written to the cloned/snapshotted vDisk, what happens when we delete a snapshot? Say we created three snapshots and deleted a second snapshot which have new data written while the base vDisk was read only, what happens to the newly written data? Will it be committed to the base vDisk or the current state snapshot will be alive and other will be deleted?

CVM with ESXi/Hyper-V

If we use the ESXi/Hyper-v as the Hypervisor, does the Satadom will be formatted(Removing AHV) and then install ESXi? What happens to CVM in this case? Any manual operation is required?

Disabling Client Authentication via API

I'm having an issue disabling client authentication via REST API. Here is my code: [code]$disableauth = @{ value='false' } $disableauth = $disableauth | CovertTo-Json try { $r = Invoke-RestMethod -Method Post -Uri https://clusterip:9440/PrismGateway/services/rest/v2.0/authconfig/client_auth -Headers $head -ContentType $content -Body $disableauth } catch { $_.Exception.Message; } [/code] When I run this command, it gives me an error of "request aborted: could not create SSL/TLS secure channel". I have a similar call I use to enable authentication, which works without issue.

Data Resiliency Status critical - what happens when another node goes down?

Hi all. I have read the document about the different failure scenarios. For me it is still not clear, what really happens, if the data resiliency status is still critical and another node fails. In the doc I read this: With two sets of physical disks that are inaccessible, there would be a chance that some VM data extents are missing completely. In our starting time when using Nutanix (version 3.x) I remember our Nutanix partner was telling me, in such a case the cluster stops to make sure data keeps consistent. Do I have some UVMs that are not working any more correctly or is cluster stopping and all UVMs are stopped? Thank you very much. Kind regards, Stefan

Python - Inventory VM and Cluster Inventory Tools v1.3

Hi In my previous publication, publish version v1.2. (https://next.nutanix.com/scripts-32/nutanix-tools-for-ahv-v1-2-32075) It was updated to v1.3 and it already extracts new information. The status of the NGT TOOLS, description, etc. and many new key validators to avoid problems. Additional I add a small script to obtain the information of the connection of the cluster to the TOR switch and the physical ports. Please check the github for more information. https://github.com/dlira2/Nutanix-tools-for-AHV I use the script in large accounts with more than 1000VMs and it works optimally.

Attempting to upload AOS binary/json always results in "Server Error"

Hi all, We are attempting to update our AOS offline (all of our clusters do not have internet access) and we have tried uploading via IE, FF and Chrome to no avail. IE "uploads forever" and Chrome and Firefox say "Server Error" everytime. We are way past due for an AOS update (5.1.0.3) and we are trying to get this done! I have a few other side questions as well -- Is the AOS upgrade process non-disruptive? [list] [*]I saw the KB about updating the AOS and it says the CVMs will reboot, but other than that it should be seamless, correct? [/list] We need to update our hypervisor (ESXi 5.5 Patch 10) and need some input there as well if possible here, since we are on a Nutanix node config and posting here seems like the right place. If not, please let me know! [list] [*]We are running a NX-1065-G4 [*]ESXi 5.5 Patch 10 [*]vCenter 6.0 [*]AOS 5.1.0.3 [*]NCC 3.1.3 [*]Foundation 3.7.2 [*]BIOS 2141203 [*]BMC 01.92 [*]LCM 1.0.e1416e5 [*]HBA MPTFW-10.00.07.00-IT

Difference between AOS , Foundation and Hyervisor

Hello Experts, I am new to Nutanix world and in middle of acquiring basic knowledge. In Prism console under software upgrade, i can see that there are components like AOS , Foundation and Hypervisor. My understanding is that the Acropolis ( AOS ) software is installed in CVM and CVM is called as Foundation. Hypervisor is either AHV or Vmware or HyperV. Is my understanding is correct ? Please clarrify Thanks Sam.

Use API to remove specific VM disks and add new disk images

We are on 5.10. I want to leverage the API(s) to remove disks from a VM, and then add new disks to a VM (using images as the sources). Which API should I use? v3 has "Update a existing VM" (sic) but I am unclear about how to (a) remove scsi:1 and scsi:2 and (b) add new disks (using images). The v2 API has "Detach disks" functionality. If I detach a disk does it get deleted? If not how do I delete it after detaching? "Attach disks" is also available in v2 but I don't see a way to use an image as the source (which I can do using ACLI). Thanks in advance for your responses.

How failover of VMs would work in case of multiple hypervisor in commercial edition.

In a Nutanix Cluster, if we have three hypervisors (say VMware / Hyper-V / AHV) if the AHV node is down, can the VMs from AHV node failover to Hyper-V or VMware hypervisors available in the same cluster in commercial edition of Nutanix.
