Expand Hybrid cluster with nodes that has different disk sizes

I have a 3 node AHV cluster that uses 2x200GB SSD + 2x6GB HDD disks for each node. Would it be possible to add nodes to this cluster that uses 2x480GB SSD + 2x6GB HDD disks?Option is to first upgrade the 200GB SSD disks to 480GB to align all nodes to the same hardware. Maybe there is some gain in that?

Query NCC versions

I have 20 clusters under management of our Prism Central and would like to know the versions of NCC installed in each. Is there a way to singularly collect this info across all PE clusters? Perhaps in nCLI even?

Two Subnets in the same native vLAN

I have a setup with two subnets in the (same) native vLAN. The first subnet is (kind of) forced on me by Unifi (router, switch, APs in in the native vLAN) and I created the second subnet for Nutanix (recommendation ist only Nutanix devices/VMs in the same subnet). Now I need a router or routes configuration in the Nutanix subnet to get access to the other subnet and the internet. What do you suggest to achieve this in a simple way or what is the recommended way of doing that?

Stacked switches with AHV?

Hello,i have some questions regarding “Switch stacking”1-) Is it possible to use " 2 stacked switches " as TOR with AHV? there will be a problem if we use this configuration?2-) The best practice is to use 2 Stacked switches or 2 individual switches?We plan to use Active-Backup configuration and conect SFP to Switch1 and the other SFP to Switch2I am not a network specialist so i am not sure if both switches are stacked, and we plug 1 SFP to SW1 and the other SFP to SW2, the active passive configuration will work

Prism Central Focus

Hello All,I have successfully installed Prism Central and it has been working well. I have configured a “view” under the focus button in the vm’s menu; however, this setting will not stay once I log out and back in. Currently the process is once I log back in I need to click on focus and pick my view. Is there a way to make that my default view? Maybe tie the view to my user account? I have included and image below to help. Thanks,Scott

Installation of ce-2020.09.16.iso results in hdparm error

When installing ce-2020.09.16.iso, I get an error about: hdparmStandardError Failed Command [hdparm -z /dev/sda] with reason [BLKRRPART Device or resource busy]My config is as follows: - Intel PC (Optiplex 9020) - USB disk with the .iso to boot from - A single Harddisk to do the installation onThis is reproducable on an Intel-NUC, exact the same issue..Now, I add an additional Harddisk (two HDs and one USB). Note that both HD’s are not carrying any nutanix data, format or whatsoever. After the boot I get a different error:Phoenix: ISO is already mountedFATAL: Couldn’t find a hypervisor and an AOS installed, please package phoenix with a hypervisor and a AOS. Please refer to Nutanix support portal for more information about this.My questions:Why do I get an hdparm error in the first place. When adding a disk, apparently to get around the hdparm error, I suppose that the ce-2020.09.16.iso supposed to provide me the hypervisor and all this.Not sure if the hdparm error is related. Furt

Upgrading VMWare

Hi there. I’m trying to plan an upgrade on our nutanix clusters from VMWare 6.5 to either 6.7 or 7.0 and I’m having a bit of a struggle figuring out the compatibility of the different VMWare versions along with our Nutanix clusters. We have two Nutanix clusters, our main site is a 7-node cluster with 5 Gen5 nodes and 2 Gen7 nodes. Our remote data center is a 6 node cluster with all Gen 6 hardware.Our main site is running AOS 5.10.5 LTS and our remote datacenter was just recently upgraded to 5.15.2 LTS in preparation for the vmware upgrade. I plan on upgrading our main site to the same AOS version of 5.15.2 LTS.Where I have an issue is that when running the VMWare Assessment Tool (VSAT) I keep seeing notifications on each cluster that certain nodes may not be compatible with VMWare 6.7 or 7.0 because of various devices that “May not be supported” yet say things like “is certified but current driver (ixgbe) is not supported”. In some cases the same exact nodes in the same cluster wit

Nutanix AOS / AVH - SFP+ 10G Direct Attach Cable for Nodes

Hi All,Current environment (~40 sites & HO) do not have any 10GbE switches and we are planning 2-node clusters per site. If using 2 x 1GbE Nic for the management like a witness communication, can we connect ESXi nodes using 10gbit ‘direct cable’ to support the workload for all VM traffic, vMotion, vmKernel, and Nutanix and most important, two node disks datastore? It should be not any issue for the Nutanix/VMware level, Switch is on L2.

vCenter 7 U1 support

We are currently on vCenter 6.7U3j and looking on my possible upgrade path to vCenter 7 I need to go straight to 7 U1.https://kb.vmware.com/s/article/67077#vCenterServer6.7to7.0Should I wait for 7 U1 support or can I expect Prism/Nutanix and Nutanix Move to play nice with vCenter 7 U1?Looking at release notes for Nutanix Move I see only vCenter 7 for example.https://portal.nutanix.com/page/documents/details?targetId=Release-Notes-Nutanix-Move-v3_6_2:Release-Notes-Nutanix-Move-v3_6_2

NGT on Debian (and other distributions)

Hi,Is there any ETA for Nutanix Guest Tools for Debian 10? Debian 11 is probably going to be released this summer, so it would be quite nice if NGT supported Debian 10. Or is there a way to “forcefully” install Nutanix Guest Tool on newer systems? Is it possible to build it ourselves to we can distribute it on our thousands of VM’s that is running?

Phoenix failed to run on G3 platform

I have an old G3 block that need to be installed for a demo.And after lots of failed tries from Foundation installation, I ended up installing the node manually.

Pre-requiste for ESXI Upgrade

Pre-requiste for ESXI Upgrade Need to enable both HA, and DRS https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.avail.doc/GUID-1D8B1384-59A4-41E2-AF05-697FC06D9EF9.html When vSphere HA performs failover and restarts virtual machines on different hosts, its first priority is the immediate availability of all virtual machines. vSphere HA uses the virtual machine's CPU and memory reservation and overhead memory to determine if a host has enough spare capacity to accommodate the virtual machine. After the virtual machines have been restarted, those hosts on which they were powered on might be heavily loaded, while other hosts are comparatively lightly loaded.In a cluster using DRS and vSphere HA with admission control turned on, virtual machines might not be evacuated from hosts entering maintenance mode. You must manually migrate the virtual machines off of the hosts using vMotion. This behavior occurs because of the resources reserved for restarting virtual machines in th

VMware hypervisor download

Are there plans to validate a version of VMware’s ESXi hypervisor that addresses recent vulnerabilities outlined here; https://www.vmware.com/security/advisories/VMSA-2020-0023.html The proposed version to address this threat is ESXi670-202010401-SG for existing 6.5 hosts or ESXi675-202010401-SG for existing 6.7 hosts. It appears that the latest json version for download from My Nutanix is 6.7.0 U3 - which is slightly older than the version being proposed to resolve the vulnerability. Thanks!
