Karbon 2.3 DVP deployment issues (centralised Prism VPN SIte2Site)

Hi there,We are currently deploying (and testing) Karbon as K8 orchestration platform for all our Nutanix platforms (worldwide). I have failed installation attempts from Prism Central.As a side note, we are using VPN Site2Site from centralised Prism Control and I can reach remote K8 VLAN from distant Nutanix deployment. The reachout tests were done with small VM belonging the the K8 VLAN testing node and via private CIDR (bidirectional tests), but utilizing the same encrypted VPN channel.This is what I’m having from karbon_core.out (PCVM):2021-10-13T21:17:12.687Z ssh.go:153: [DEBUG] [k8s_cluster=RGS-PA-K8-STAGING] On 10.20.25.130:22 executing: docker plugin inspect nutanix2021-10-13T21:17:12.825Z ssh.go:166: [WARN] [k8s_cluster=RGS-PA-K8-STAGING] Run cmd failed: Failed to run command: on host(10.20.25.130:22) cmd(docker plugin inspect nutanix) error: "Process exited with status 1", output: "Error: No such plugin: nutanix\n[]\n"2021-10-13T21:17:12.825Z sshutils.go:44: [ERROR] [k8s_clust

Which hypervisor Hyper-V or AHV?

Hi, New to the forum, we recently had our Nutanix servers delivered and we are planning to do the install in the coming weeks. We haven’t decided which hypervisor to go with yet its either going to be Hyper-V or AHV. I just wanted to know peoples experiences that they have had? We currently use Hyper-V, so we are comfortable with that but all the nice features seems to be heading to AHV/Prism. I would be grateful for your thoughts and comments Thank you

Number of Disk per node

We are considering AHV for our environment. I notice that the OEM partner product list https://www.nutanix.com/partners/oem has fixed set of disks. Most of the hardware in the list are capable to be installed with more disks. For example Fujitsu servers are capable of 12 x 3.5 + 4 x 2.5 (on the rear),Can we utilize all disk slots in a configuration like 12 x 4TB NL-SAS + 4 x 1.92TB 2.5” SSD or 4 x 1.6TB NvME ?

I check at prism and there’s a warning saying the hosts are not connected to vCenter. Anyone encounter this issue before?

Foundation fails to mount Phoenix Image

I'm looking for some advice.My company recently purchased a used 3460-G4. We're a professional services firm and we want to have it for our lab so we can stand up stuff like ERA, CALM, etc. and bang around on it. You know, lab stuff!We have been trying to Foundation (4.5.4.1 & 4.5.3.1) the block but I am running into a problem with Foundation failing when trying to mount the Phoenix image on the nodes. Here's how things currently stand:BIOS has been upgraded to latest recommended version on Nutanix Support site. (G4G5T6.0)BMC firmware has been upgraded to latest recommended version on Nutanix Support site. (3.64)Each node has x2 SSDs, which this system appears to recognize (I ran an ESXi installer on one of the nodes to test. The installers saw the drives)Each node has 64GB of RAM. The RAM is confirmed to be compatible according to SuperMicro's site.The Motherboard is the X10DRT-P from SuperMicro.IPMI has been set on each node and I can log into the IPMI mgmt page.At first I was wo

CVM can't ping other hosts in the cluster

I have a 3 node cluster with ESXI 6.7 and AOS 5.15.2. I’m unable to run any LCM tasks as the inventory fails to get the ESXI scratch space on the hosts. After troubleshooting SSH issues, I discovered I’m not able to even ping the other hosts in the cluster, via IP or hostname. I can ping the other CVMs with no issues, just not the hosts. However I’m able to ping each CVM and other hosts with no issue from the host itself, so the issue only exists when the CVM is the source and the other ESXI hosts in the cluster are the destination.I’ve restarted the hosts and CVMs and ensures the hosts are patched and updated. The hosts are all on the same subnet and no firewall exists between them. Any suggestions would be appreciated, thanks!

hyper-v cluster conversion

We are running a nutanix cluster with Hyper-v. this was the worst thing we could do when we started with nutanix. We know that now. But my main question is, is there a way of getting this cluster converted to AHV? It's a Dell XC cluster with 2 blocks and 5 nodes. regards

Time Sync on Nutanix Cluster

Here’s my problem. Node A & B are synchronizing to the wrong host. Node C is synchronizing to the right host. This is the behavior I see on the CVMs. When I do “hostssh ntpq -pn”, the hypervisors (AHV) are reporting the correct ntp server. How do I bring nodes A & B back inline to what they should be? I tried manually correcting their ntp.conf files with the correct IP and restarted the ntpd service. No change and eventually the ntp.conf files changed to the wrong settings. Not sure how to wrestle this one to the ground.

Is there a detailed HCL?

Hi all!I’m looking for a HCL that details the exact firmware versions of specific components of a server to make sure that we are in the clear before we install or upgrade Nutanix.As far as I can tell there isn’t anyone to be found, at least not for someone who doesn’t have an account for the support portal (and I find it pretty odd to “hide” the HCL).I know there are HCL’s to be found outside of the support portal but those are extremely generic.Is there an HCL that is this detailed or is it only through trial and error we can figure out if we have the correct firmware?Thanks.

NutanixManagementShare change RF2 to RF3

Hi all,Running AOS 5.10.5, i have changed my cluster from RF2 to RF3, including my main container and the “SelfServiceContainer”,however a week after the change I’m still seeing this error regarding extent groups,I believe that this is due to NutanixManagementShare still being RF2 (with no ability to change it, since its a systemmanaged container), or is there some other reason?

IPMI port vulnerability (VNC protocol enabled)

Hi there.A security check on my nutanix clusters (8 nodes) revealed that the IPMI port on every nodes is vulnerable cause the VNC protocol is used to access them through port 5900.Issue:"...Virtual Network Computing (VNC) provides remote users with access to the system it it installed on. If this service is compromised, the user can gain complete control of the system...."Remediation:"...Remove or disable this service..."What are my options? It is possible to disable these ports without affecting the performance of the NUTANIX cluster.Thanks in advance.

Customized Prism Central name on browser tab

Hi guys, a non technical question about a customization option that I can’t find anywhere. I have two Prism Central used for Synchronous replication. To Identify them at first sight I have customized title and colors of the login page. It was a bit disappointing to not find the customized name on the browser tab or at least on the menu bar title. Even after editing the cluster params to give a name to the PC cluster (only one VM as for now) the name stick on “Prism Central” on the tab and “Prism” on the menu bar.Considering I’m working on a Synchronous replication and that all the objects involved have the same name (Protection Policies, Recovery plans, categories), sometimes i found myself working on the wrong Prism Central. It would be easier to have the PC name always visibile. Any idea? Thanks in advanceil_gianK’ Tab and menu bar title
