Deployment Success

The following document states that the CVM will be Redirected to another CVM after 30 seconds of inactivity.https://portal.nutanix.com/page/documents/details?targetId=Web-Console-Guide-Prism-v6_0:arc-failure-modes-c.html What response does the cluster request from Stargate?I want to know the details that the cluster requests to Stargate for 30 seconds.

What will be total usable space for the hypervisor and best practice to allocate the storage.I have three new Nutanix nodes. Physical capacity of Cluster is 79.04 TB and Free logical is 39.52 TB in RF2.

The following migrations are not recommended, but can be performed with some limitations. Exchange should be migrated by installing newer versions of Exchange Server in parallel with existing production environments, then move user mailboxes from the old system to the new one. Domain controllers should be migrated by preparing a new domain controller, and then migrating the Flexible Single Master Operations (FSMO) roles. Move migrates database VMs similar to any other VMs;however, the migration happens at the VM level, not the application level. Move will not perform any application-level changes, disk layout updates or best practices on the migrated VM. The above approach should be fine for smaller SQL DB servers and for servers without PCI Pass-through, pRDM disks or multi-writer disks (clustered NTFS). Also, for larger SQL DB servers, Nutanix recommends you to apply Nutanix best practices to create additional vDisks and rebalance data across those disks to take advantage o

Hello!Need help to understand problem and help. We have 4 nodes. Today saw one node have a problem with the power supply:use this command:ncc health_checks hardware_checks ipmi_checks power_supply_checkResult:1# FAIL: Power supply 1 is down on block block <name>2# FAIL: Power supply 1 is down on block block <name>My next action if physically all fine with PSU.Find in KB7386:Restore the power supply as soon as possible...

HI all, I'm preparing a change on the cluster (6 node cluster running AHV). I need to re-ip cvm's and ahv's and add them to a specific vlan (now they are not in a vlan). Before I do this in production I decided to do this on the test lab. (old baby, 4 node G5). I've followed this guide: https://next.nutanix.com/installation-configuration-23/physical-relocation-of-nutanix-clusters-38403 but got stuck step 7 after booting the cvm's. The ouput of svmips shows the old cvm ip's but they are all booted with the new ones. (and accessible via ssh on the new ip's)The output of hostips shows the old ahv ip's byt the are all booted with the new ones. (and accassible via ssh on the new ip's). I must also say that the external_ip_reconfig script hangs at a specific time and now the command “cluster start” gives an error the the cluster is still in reconfigure mode. Anyone here who has the golden tip to get the command svmips and hostips to show the correct ip's? (zk_server_config_file also had the

I run a 6-node nutanix cluster, and planing to run some containers (LXC) , inside VM using ZFS pool, to leverage on easy clone, migrate, snapshot the containers mainly to transport those clones to other system (DR) I read that ZFS need to deal directly with disks hardware to be sure about what is or what is not actually written to disks.  Is ZFS suaitable or not, being run on top of nutanix platform, concerning the data corruption risk or losing pool, because it can’t deal directly with disk hardware? Hardware is supermicro bundled with nutanix-enterprise.

I have AHV cluster configured 5.5 with multi homing and now i want to add new node to existing cluster. What is the right procedure.

We recently performed a cluster shutdown with hardware power off of an AHV cluster running AOS 5.15.5.1.We powered on all the nodes, and waited 10 minutes for the AHV hypervisor to boot and the CVMs to boot and get ready.Even after 30 minutes the CVMs did not recognise the confirmed correct password for the “nutanix” userID during ssh login attempt to any CVM.Fortunately one SSH key had previously been registered into Prism Element, which allowed SSH via this key.  The cluster was NOT configured to be locked down.The key owner successfully connected to a CVM via SSH and performed sudo passwd set of the “nutanix” userID to a confirmed password.Despite setting this password, the same CVM still refused to accept the “nutanix” userID and confirmed correct password during SSH password login. I am suspecting that with the cluster service stopped, but with one SSH key present, that the CVMs operate as if lockdown were enabled.Can someone please confirm for this?This prevented the password hol

Do you think is there any way i can migrate data from standalone server to the AHV?

Nutanix, AHV, MS Server 2016 installed with IIS, Media Wiki.Out of the blue, the server performs very slow.  The MediaWiki site takes forever to load ( at times a Server 500 error appears when going to the MediaWiki site from a desktop).  Opening the console shows the Server logon window but very slow.  Everything is very slow.  Once logged on, it takes almost 20 min for the server management window to open.Currently, vCPU=6, Cores per CPU=4, RAM 16CPU Usage around 10% and Memory usage around 17%Only server that acts like that.  Ran DISM /Online /Cleanup-Image /ScanHealth and so on and everything is ok/ no problems. Rebooted all hosts.Not sure what caused this all of a sudden ….

I want to transfer Prism Alerts, Events logs to another log collection server. A log collection server is a solution called innerbus. How can I send it?

Is AOS single node cluster upgrade an disruptive action?Thanks!

Hi,I have three identical nodes (basic Lenovo servers) but one performs really slowly compared to the others. The disks aren’t the same across all three though. I wonder if anyone has any ideas which difference might be causing the performance issues: Firstly the HDDs are 4TB in the two ‘good’ nodes and 2TB in the ‘slower’ one. I wouldn’t expect that to cause performance issues, just overall capacity will be limited? To be fair the 2TB is a WD ‘green’ and the 4TBs are WD ‘red’ drives. Secondly the ‘slower’ host has a Samsung Pro 840 256GB SSD which Prism reports as often having a higher latency than the HDDs! See the image below  Are they known for being poor in this kind of environment? I’m not really stressing them. Any good logs to see performance issues? I can see the HDD activity light is permanently on on the slower host. Cheers,Steve

Beside the “classical” Monitoring with snmp or agent based version now we are talking about Metrics and the Monitorng of LiveData with the OpenSource Project Prometheus.

Hello, all. We’re running vCenter 7 with AOS 5.15.x, and I’m learning about how VMware has now decoupled the DRS/HA cluster availability from vCenter appliance and moved that into a three VM cluster (the vCLS VMs).In the interest of trying to update our graceful startup/shutdown documentation and code snippets/scripts, I’m trying to figure out how to handle these vCLS VMs. They reside on the Nutanix shared storage, so I obviously would like to shut them down before gracefully shutting down the Nutanix CVMs/ADSF cluster as well as ensure the CVMs are up and cluster is good before allowing them to power back on using that storage. Evidently, these vCLS VMs are very aggressive about powering back on or recreating themselves once deleted, so I’m a little unsure what to expect.So with regard to powering back on the ESX hosts, I assume when I take them back out of maintenance mode the CVMs will be powered back on (or maybe I have to do that manually?), and after waiting a few minutes, I woul

While it is not as a straightforward process as we would like for it to be there is an option to add a NIC to your Move VM. Login to Prism Element Add New NIC to the Nutanix-Move appliance and select the network Launch the console of Nutanix Move appliance. Switch to root user Use vi editor or any other editor of your choice to open the file /etc/network/interfaces Add the second interface eth1 configuration in the format below based on DHCP/Static IP addressing. Restart the networking service.Please Note: If you are using Move 3.0.3 or above you can skip Step-7 and Step-8. That'll be taken care automatically. There will be an existing script named "start-xtract" under "/opt/xtract/bin". Overwrite that script with the one provided in the KB (see link below). Change the permissions for the script. Stop iptables and restart move services. Verify the new eth1 interface configuration using "ifconfig eth1". See KB7399 - Procedure to add a second NIC interface on Move v3.0.2 for detailed ins

Hello all..is there a list with model number somewhere of the Nutanix supported NICs?  I am looking for the cheapest 1Gb dual NICs Nutanix supported that I can get from Amazon or ebay or the cheapest 10Gb..I was reading that supermicro Nic is supported but I don’t see model number so I was wandering if the Supermicro AOC-SG-12 is supported since that card cost about $35..my understanding is the CE and commercial support the same NICs now. My use case is CE for homelab. thanks
