Product mixing restrictions 

Let's say you want to mix platforms, nodes or a sub-components in your cluster, what are the restrictions?  There are multiple components that you could mix, we took everything into consideration and explained it’s compatibility. In our portal, you can find the Hardware, OS, Storage, Encryption, DIMM, Hypervisor and vSphere restrictions. check out our Compatibility Matrix. For example, if you want to mix the hardware you can mix nodes that use different CPU families in the same cluster, but not in the same block.  e.g, a cluster can contain nodes from any NX generation, but a G6 block must contain only G6 nodes, a G7 block must contain only G7 nodes, and so on. For AOS, all the Controller VMs (CVMs) in a cluster must use the same version of AOS. Note: do not configure a cluster that violates any of the rules as it could lead to an unexpected behavior.  For the full documentation and rules check out this: https://support-portal.nutanix.com/#/page/docs/details?targetId=Hardware-Admin-Ref

Dell XC740xd Drive Placement

Can someone confirm the drive placement for SSD and the SATA drives in our Dell XC740xd servers?   On one cluster of servers, there are four SSD drives in bays 0-3 and in the other two clusters the SSDs are in the last four bays.    I have only seen the SSD drives in the first four drive bays.

UPGRADE NCC versions that include an installer file inside a compressed tar file fail

Hi    I followed the steps in page to upgrade NCC. I can upgrade NCC by a single installer file (ncc_installer_filename.sh) successfully. But I cannot upgrade NCC by a compressed tar file (ncc_installer_filename.tar.gz). After extract the installation package, I type command to run the install script as below. It showed “Installation of ncc failed on node xx.xx.xx.xx” . I tired to run the script on each cluster, they generated the same error. How to troubleshoot the issue?

All things networking

If you are anything like me then you prefer to figure out things by yourself instead of asking for assistance. While this is arguably the most efficient method of achieving a positive outcome, knowing where to find the right information as well as knowing that it exists is crucial.   Also, networking is complicated. Being fundamental, a mistake often makes a profound impact on the environment. How to create a virtual bridge? How to use manage_ovs command? How to change VLAN on VM NIC? How to add or remove VLAN on CVM and AHV host? How to configure LACP? How to isolate 1G NICs from the rest of the NICs?   The answers to the above and more as well as useful links – all can be found in KB-2090 AHV | Host and Guest Networking   Care to read more?

How to install new NIC card to an AHV cluster

Only applies to AOS 5.15 and earlier versionsShould you wish to add NIC cards to your nodes there are several steps to follow to ensure that the process is successful. Verify that NIC card model is compatible with the hardware. In case of an NX platform the best way would be to contact Nutanix account team. Look for the documentation describing the process. Nutanix portal has a Hardware replacement section for instructions on all hardware component replacements for all NX platforms.  Once the card is automatically detected the bond and uplinks configuration must be updated using manage_ovs command from CVM.

Remote site connectivity not normal

Hi A remote site on AWS has been configured earlier. The time sync drifted too far but that has been fixed. The remote site in Data Protection has this alert "Remote site connectivity not normal." It is an AWS instance. The remote CVM IP address is 10.162.10.115. The host ipaddress is unknown, the firewall rules are fully open and replication seems to be occuring. There is a site to site VPN specificaly for this instance It looks as though the aWS remote site was never configured with the local cluster as a remote site which is what most of the webinars and documentation suggest. The IP address will not open a web page on http or https, the only communication available to the AWS node is SSH. How does the configurationof the remote site get completed or how do I get rid of this alert ?? Prisim: 5.6.1 NCC Version: 3.5.2 LCM Version: 1.4.2381 Nutanix 20170830.124 (in cluster, standard AWS instance) Thanks

LCM Troubleshooting | Part -1 Pre-checks

Life-cycle Manager has made the life of every Nutanix Admin easy by providing a 1-click approach to upgrade the firmware and in the latest version, the hypervisor seamlessly.     Let’s consider a scenario, where you went ahead with an LCM upgrade but noticed it failing as some pre-checks failed.     What are these pre-checks?     Before any upgrade, LCM runs a series of pre-checks to confirm the cluster stability and if all the prerequisites are fulfilled before  proceeding with the upgrade.   Do we have a document listing all the pre-checks and their resolution?    The following document lists all the pre-check, their description and resolution. This might come in handy if we are trying to troubleshoot as to why the LCM pre-checks have failed.   KB-4584   Want to know more about Life Cycle Manager and its features?  Give the following document a coffee read!    LCM Guide

AOS 5.16 can not update as 5.11.2.1 release same day

Hi everyone,   I m new to Nutanix and have just deployed my first cluster. I did all the updates I could find in Upgrade Software Settings. It brought the nodes up to 5.11.2.1 . I tried to run the checks again and it shows no available versions. I saw the notice for the release of 5.16 so I downloaded the manual update binary file and meta file.   When I try to update it says unsupported.  Edit:   NOT SUPPORTED Current version was released after the Target version was released. Upgrading to Target Release version is not supported in this case.     I check the support upgrade path wizard in My Nutanix and it says the 5.11.2.1 is newer then the 5.16 yet they were released the same day!? The Upgrade path shows that if I had the 5.11.2 I could update to 5.16 but not 5.11.2.1 ?? Will Nutanix have an update path for this? or am I stuck for a while?   thanks everyone.   Scott

Can external legacy storage be accessed via Nutanix AHV or ESXi?

There can be legitimate cases where access to external storage, such as massive tape libraries, massive disk archives is needed to some, but not all VMs running in a Nutanix cluster.  These VMs would be ideally under the AHV hypervisor, but is ESXi is an acceptable alternative.  These external storage systems would likely support 10GbE iSCSI (and faster) and/or 8 gbit fibre channel or faster. I understand that supporting such external access would make the VM “special” and would restrict VM mobility to other specific nodes that were configured for similar external access. The mobility issues are a later discussion, if external storage access is possible. If the external storage was a NAS device, running NFS and/or SMB, I believe it would be straigntforward … just define the external IP address in the VM, and access the data from the VM.  The same technique could be used for external iSCSI devices, for Ethernet iSCSi.   In many cases, if the external storage needed very high performance

Hardware Memory Compatibility

I have an opportunity to acquire some retired Nutanix memory.  The retired memory is  NX-1065-G5 nodes and our Cluster is NX-6035-G5.  From what I have been able to trace they appear to use the same memory modules.  Can anyone confirm this?

Creating Phoenix bundle iso locally

Let’s say you want to add a node to the cluster, now, the AOS version in the new node to be added should be the same for quick expansion. To do so, you need to use a phoenix image bundled with AOS or in some cases, AOS + AHV bundled image to perform imaging in one go.  Instead of creating a new case with support and save your time too, the fastest way would be to create one on your own. There are 2 ways to do so:- 1. Creating a Phoenix ISO via CVM 2. Creating an ISO by Using a Foundation VM (if option 1 cannot be performed) To know in detail regarding how to go about the above-mentioned ways, take a look at KB-3523.

Upgrading memory in a Nutanix cluster.

The business is growing, and this means more users, more virtual desktops, and you’re likely going to need more RAM. You could add a node or two, but what if rack space isn’t readily available?  The existing nodes may still have room to grow. How do we add memory to nodes in a Nutanix cluster? The process for upgrading memory is covered in this KB: HW: Upgrading Physical Memory You should understand the restrictions and have a plan before purchasing DIMMs. If you need to review supported memory configurations, such as what DIMM capacities are supported and which slots to fill, check the NX Series Hardware Administration Guide for details. There are restrictions on mixing memory in the same node. You can’t just add any DIMM that fits into an existing node, but if each node has some slots available there are options to move forward. You could purchase new DIMMs to populate one node and complete this replacement first, and then use the removed DIMMs to add memory capacity to other nodes i

Clear critical alerts with a later date

Hi,I had a problem with the NTP server configured on the Nutanix cluster, unintentionally changed the date to 09012020 instead of 01092020,  the point is that after solving that problem, now the cluster reports to me Critical alerts dated September 1, 2020. The date of the NTP is already corrected, but Web Console  shows some critical alerts, but those alerts are not shown with ncli, but  are shown with Alert tool. I have try to aknowledge and  resolved them, but they are NOT eliminated from alert_list.Does anyone know what I can do so that the web console no longer shows them?

When all is almost lost - forgotten root password on AHV

It happens to the best of us. We are human beings and we make mistakes. Sometimes it means that we forget or lose root passwords to one or more of our AHV hosts.   There are two ways out of that situation. Log into the AHV host from CVM using the host's local IP address. Make sure that you are logging into the CVM of the problematic host. Change root password.  Re-image the AHV host.
