Series of bad judgements

Hi all,First time posting, a little background on me and my environment. I am a VCP and have been doing VMware virtualization for the last 20 years. I have 2 Nutanix blocks at home loaded with 3060-G7’s. It’s a pretty nice setup (It went out of warranty, so was given to me to take home, so pretty lucky there.) So I got it all loaded up with community edition and everything was running smooth. I bought a new Uni-Fi 10gb switch for home, as well as a plethora of other unifi products. Here is where I fouled up big time:I set up link aggregation Active-Active on my only vswitch. After changing it, I realized I didn’t have any SFP’s for my switch. So I connected them to my UDM-SE. I assumed my UDM-SE supported LACP, but it did not and it threw my entire network into a frenzy. I eventually figured out that having the blades plugged into my UDM-SE, with LACP enabled, was causing a lot of routing confusion (which took my own home network offline for sometime). Next bad decision, I deleted the

Nutanix CE fails to install

I have been trying to install Nutanix CE on a bear-metal machine (homelab) to day but it constantly fails. It seems that the culprit is related to instsvcdrv.service not being able to start. I’ve recreated the USB drive for a few times with various drives but the behavior is the same.It’s probably something else hardware related but I can’t pin point it.The system is a AMD 7950x with 96GB RAM and 3 x 990 PRO NVME drives which worked fine with Proxmox.

CE installation network connectiviy issue

I’m attempting a new installation of CE. The installation itself completes with no apparent errors but I can’t connect to either the AHV or CVM IP’s assigned during the install. The onboard server NIC is a four port HPE 331i which has a Broadcom chipset. Three of the ports are connected to the same network vlan that the IP addresses are tied to. I have tried trunking them on the switch side, leaving them all on as individual ports and enabling/disabling each so that only one connects at a time and have had no luck with any of these strategies. I’ve tried to log into the console of the CE server but haven’t been able to find credentials that work. Any ideas would be much appreciated since I’m so close to be done hopefully.

Nutanix CE installation fails

I am attempting to Install CE on a HPE Proliant DL380Gen10 server with 128GB RAM, two Xeon 4116 cpus, one 480 SSD, and four 600Gb HDD’s I created a USB install drive using Rufus and the newest version of CE.

upgarde AOS only without upgrading the esxi

Hello Experts,It is possible to update the cluster to a version of AOS that supports ESXi 6.7 U3. However, we do not have a license for ESXi 7 or 8.We must upgrade and deploy the PC. The current version is 5.20.3.5. After reviewing the compatibility matrix on the Nutanix portal, I discovered that this version of AOS 6.5.3.7 is compatible with ESXI 6.7 U2 and U3. did any one tested that before ?and i would like to deploy PC,PS : this cluster has esxi 6.7 u3 as hypervisor

Which goes first Host or CVM?

Newbie trying to configure Nutanix.Setup:Dell server with iDRAC VLAN’s are setup on the switch Nutanix is installed. Both the Host and the CVM have an IP address in the same VLAN (100)Questions:Should I configure the VLAN on the CVM first or on the host? It seems if I configure the CVM first I can then configure the host. If I configure the host first I can’t get to the CVM. (expected) When I configure the CVM it never seems to return so I have to hard reset the host. Setting the CVM tag back to 0 it does come back.Commands:On the host: ovs-vsctl set port br0 tag=<vlan tag> On the CVM: change_cvm_vlan <vlan tag>

New install (bare metal r820) of CE (Phoenix 6.8.1) Can't select virtual disk for CVM

Hi all, new to Nutanix here likely for the same reason a million other folk are trying it out. I’ve managed to find the download (though not exactly straight forward) for Phoenix 6.8.1 CE and am attempting to first time install on an r820 with 5 enterprise ssd sas in front bay. I’ve split the first off into it’s own virtual drive at full capacity (300something gb) for H install. The second and third off into their own individual virtual drives for CVM1 and CVM2. Then the last two combined into one virtual drive for D.  I am able to select the virtual drives for H and D however the CVMS tell me it can’t be selected because the drives must be SSD which they are. Drives are fine and the virtual disks are recognized just not allowed to be selected. Any insight is greatly appreciated I’d love to test Nutanix out but documentation has been all over and even downloading (from a link in a seemingly random forum post) my confidence is a bit waned.
