Adding a G6 node to existing G5 block

Hi All, Is it possible that we add a G6 node to an existing Nutanix Block running 3 1065-G5 nodes? or we will have to add another Nutanix block containing a single G6 node and make it part of the existing cluster?

DR Scenario

We have a scenario in which we are running VMware vSphere environment on existing servers and planning to deploy a DR site. Is it possible that we deploy a Nutanix AHV environment at the DR site and replicate from the existing ESXi environment at the Production site to the Nutanix DR site somehow? We are currently using Veeam backup and replication for VMware for backup. What is the possibility of such a requirement?

Networking with Dell Switches: VLANs and NICs

Hi All Is anybody else just going round and round in circles with Nutanix and the network it resides on? I am getting soooo peeeeeee'd off!! The man at the show said easy peasy, 15 minutes to deploy, which 15 minutes? The last 15 in 2019? Dell supplied, but don't really know the product so they pass calls off to Nutanix who do their bit (very well, no complaint there) but then hand the things about Dell back to Dell, so I am not getting a joined up answer. So the crux is that I don't have a stable network and I am ready to rip it all out and go back to VMware. Unfortunately my budget has gone and I have to rely on Communities for answers - not a lot forthcoming. Is anyone else having these sort of problems or is it just me?

Prism Network view anomaly?

Hi All I have something odd in my Network view in Prism - I have 3 switches ( 1 switch is a 2 switch stack) but the view shows 5 switches, 2 classified as None. The None entries have the ip addresses of one of the single recognised switches and the stack which is already identified. The other odd thing is that the Nones have ports that I would expect to see in the identified switches. Can anyone tell me how to correct this?

SSH access to CVM and AHV to check on the security settings enforcement

Dear contributors, We have purchased Nutanix appliances and I am working as part of the IT Security team. We have enforced the security settings on CVM and AHV (STIG, banner, ...) and, as part of our duties, we carry out regular checks to make sure that the security settings have not been altered. For this, we would like to have nominative accounts which are able to connect through SSH and be able to check on the settings of the components. Is it possible to do? If yes, how can we proceed? Thank you in advance for your assistance.

AFS - Home directory permissions allow ALL users to read ALL home folders?

We just set up AFS. On the home directories, we expected that like a Windows home directory setup, the user would be the only person able to view their home folder. (and Domain Admins of course). But, on AFS per this doc https://portal.nutanix.com/#/page/docs/details?targetId=Acropolis-File-Services-Guide-v20:Acropolis-File-Services-Guide-v20 and also per our experience it seems like ALL USERS can view everybody's folder and contents. This seems like a security problem since HOME directories are typically expected to allow only the user to view their data. Is this by design? It seems like a significant security challenge and much different from how this would typically be set up on a Windows file server.

Prism and DVS Iissue

I have encountered an issue while migrating to a dvs, I am running esxi 6.5 on a 3 node cluster. The setup is new so there are no VMs apart from the CVMs and a test VM on the host. The dvs already exists and I am doing one node at a time and as such I added one of the NICs from node A to the dvs. I then did a quick test with the test VM on each port group I have configured to confirm connectivity. I then attempted to migrate the VM Network port group created on vSwitch0 that the CVM on node A was connected to, the migration "worked" but connectivity to the CVM was lost. In addition to losing connectivity to the CVM on node A, I am now unable to access prism from any of the CVMs or cluster IP. The page loads but once I attempt to login nothing happens. I even powered off node A in hopes that I can get to prism but still no luck. All CVMs and the cluster IP are reachable via IP, the esxi hosts for node B and C are also fine and reachable. Not sure where to go from here other than tear do

should i use a witness

I am looking for other customers who have used the witness feature. We have three buildings each about 1 mile from each other. 10g fiber between them. We have two Nutanix clusters, one in each of two of the buildings. We have the ultimate licensing and are already using Metro clustering. I have the fail over set to manual. Today I setup a witness server in the third building. As far as I can tell everything is working. The real question is should I use it? Is anyone using the witness. Does it cause more problems than it solves. At least with manual I have full control when a fail over happens. So far it has been easier to fix my issues than to fail over and almost all issues are network related not nutanix.

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. I've created and recreated several times using different varieties of below commands and still same outcome. Some commands below are from various tries, but same result. [b]Error when powering on VM with virtual NIC[/b] Operation failed: InternalException: kNetworkError: OVS error (10.1.16.103 create_local_port): Error not a valid bridge: br1 [b]Host A - ovs show[/b] [root@HOSTA ~]# ovs-vsctl show 48fd5ca1-d898-425e-9b11-484eaceaba94 Bridge "br0"

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

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]

Keyboard Layout - Prism Console

We are using Nutanix ( AOS 5.5.0.6) with AHV-Hypervisor. Connecting to a VM(W2K12,W2K8, German) via Prim & VNC-Console there is no possibility to change Keyboard-Layout. Our Computers are on Win7 - German with German QWERTZ - Keyboard Layout. No matter which Browser we are using (IE11, Chrome, Firefox) we can not type special characters like \ / . We also tried the American Key for / \ without success. Is there a posibility to fix this Problem? Or is it a Bug ? Looking forward to hear your comments: F.Hil

Remote Site vStore Mapping not accessible

After a failed upgrade that resulted in a failed node, we reinstalled the node and added it as a remote site so we could migrate to it and reinstall the other nodes. When I added the site on the old cluster it works as expected, but on the reinstalled node I cant add any vStore Mappings and are instead greeted with this message "Remote Datastores are either not configured or not accessible." When I run [i]ncli> remote-site list[/i] on the reinstalled node I get: Status : unreachable and on the old cluster: Status : relationship established Is there any log output/command that could help me troubleshoot this further?

Oracle + Dual hypervisors in 1 Cluster

Hey Guys, I have a question: Let's say a customer needs to deploy some Oracle databases. As wel all know, licensing is expensive.. In this scenario they have a 11 node cluster. Would it be possible to have 2 nodes run on AHV with oracle whilst the remaining 9 nodes run on ESXI?(They only need 2 nodes hence they don't want to use a third node & create another cluster + They would like to benefit from erase coding.) This would cut the Oracle costs by a huge amount. Or are there any other solutions for this? Thanks in advance! Sebastiaan
