Guidelines of AOS for TWO-NODE CLUSTER

A traditional Nutanix cluster requires a minimum of three nodes, but Nutanix also offers the option of a one-node or two-node cluster for ROBO implementation. Both of these have a minimum requirement for the CVM to be allocated with 6 vCPUs and 20 GB memory.Specifically for two-node, there have been several improvements in 5.10 to ensure optimal health of the cluster.Customers should upgrade to a minimum version of AOS 5.10.7 to avoid encountering any of the potential service impacting issues present in earlier releases of AOS.The table provides a summary of improvements in the document here-https://portal.nutanix.com/page/documents/kbs/details?targetId=kA00e0000009DaXCAUMore information about two node cluster can be found out -https://portal.nutanix.com/page/documents/details?targetId=Web-Console-Guide-Prism-v5_18:wc-cluster-two-node-c.htmlROBO implementation meaning - Short for remote office, branch office ROBO is a term used to refer to any off-site office that connects to the organ

4 SFP+ on AHV

Hello,have you guys ever configure a 4 SFP + Nutanix cluster with AHV? i understand that the 4 SFP + will be configured as active-passive in a same bond... but only 1 SFP should be used. There is a better way to configure network on AHV to improve and use the other SFP+??? i mean, for example, separate the traffic between user VMs and CVM (storage traffic)

Physical Relocation of Nutanix clusters

So you have decided to relocate your Nutanix cluster to a different data center. Here are a few things to consider and a brief overview of steps to follow for seamless transition. Caution: This information is only provided to serve as a guide to plan your move. Please engage Nutanix Support if you have any concerns or questions following this process. Before you decide to move: Consider the possibility of incorporating the existing IP address schema into the new infrastructure by reconfiguring the router and switches instead of Nutanix nodes and CVMs. If that is not possible, proceed with this guide. Before you unplug everything:Refer to these guides for the procedure.Doc 1 (CVMs) CHANGING THE CONTROLLER VM IP ADDRESSESDoc 2 (AHV hosts) CHANGING THE IP ADDRESS OF AN ACROPOLIS HOSTDoc 3 (IPMI) CHANGING AN IPMI IP ADDRESS A few things to note:1. Since the cluster is being relocated and the new network will not be able to communicate with the old network, you will need to run through so

Re-Image Cluster with Phoenix

Hello,I’ve just reimagined a block with 4 nodes (NX-1065-G4) to use in our lab using Phoenix image (created following this article https://portal.nutanix.com/page/documents/details?targetId=Field-Installation-Guide-v3-12:v31-phoenix-files-r.html#reference_bbk_vnx_p4).I’m using ESXi 7.0.0 build 15843807 and NOS 5.15.2. Hypervisor and CVMs have been correctly installed (following this https://portal.nutanix.com/page/documents/details?targetId=Field-Installation-Guide-v3-12:v31-node-install-cvm-t.html) but CVM does not have an IP configured. I’ve tried to configure CVM IP using “external_ip_reconfig” scripts but i get an error: How can i configure CVMs’ IP?Note: i’ve used Phoneix because Foundation failed several times with a “dependencies” error.Thanks, kind regards

Converting to AHV without DRS

Hi all,We recently purchased a new G7 and during this new install we converted all of our VMs to AHV using Move and we are successfully running on AOS/AHV. Working great.We now would like to convert our old 1050 with ESX/vCenter to AHV although we are hitting the DRS roadblock.We do not have a DRS license to enable this feature.We have also tried a “Trial License” and this doesn’t appear to be the best route (upgrading all kinds of vmware items just to get a “trial license enabled DRS “just to convert to AHV)My question is, now that our old cluster is decommissioned (All VMs are now on the new cluster), what would be my best approach at converting this old cluster to AHV and not having the “Convert Cluster” option hanging us up with DRS not enabled? Any input is appreciated.

Fresh Intall Nutanix Cluster - IPMI default password

Hello all,I’ve just finished the basic installation of a new 3 nodes Nutanix Cluster (NX-1065-G7 node). When i try to enter the IPMI password nothing happens. It seems the password is wrong. I have tried the default ADMIN/ADMIN password but it doesn’t worked (also admin/admin).Did the default password change with the release 5.15.x of AOS ?For information, the cluster has been created with the following parameters : AOS 5.15.2 Foundation VM 4.5.4.1 ESXi 6.7U3The “ipmitool user list” show me an “ADMIN” user with ID 2, so i think the account is correctly created. I ve tried on each of the 3 nodes and it’s still the same. So if the password set is ADMIN by default and is not working, can i safely change it with the ipmitool command ? Thx for your answers :)

Metro Availability Witness Option

You have the option of adding a Witness to a Metro Availability configuration (see Data Protection Guidelines (Metro Availability)). A "Witness" is a special VM that monitors the Metro Availability configuration health. The Witness resides in a separate failure domain to provide an outside view that can distinguish a site failure from a network interruption between the Metro Availability sites. The goal of the Witness is to automate failovers in case of site failures or inter-site network failures. The main functions of a Witness include: Making a failover decision in the event of a site or inter-site network failure. Avoiding a split brain condition where the same storage container is active on both sites due to (for example) a WAN failure. Handling situations where a single storage or network domain fails. Metro Availability Failure Process (no Witness)In the event of either a primary site failure (the site where the Metro storage container is currently active) or the link betwee

What is a Never-Schedulable Node?

If you want to increase data storage on your Nutanix cluster, but do not want any AHV VMs to run on that node, you can add a Never-Schedulable Node to your cluster. AOS will not run any VMs on a never-schedulable node, whether at the time of deployment of new VMs, during the migration of VMs from one host to another (in the event of a host failure), or during any other VM operations. Therefore, a never-schedulable node configuration ensures that no additional compute resources such as CPUs are consumed from the Nutanix cluster.With the release of Foundation 4.1 and higher, any G6 or G7 node can now be used as a storage-only node. You can add any number of never-schedulable nodes to your cluster!To learn more about the requirements and the procedure to add this node, click here. Also, check out KB-6819 for further instructions.

IPMI - Cold reset, Partial reset and Factory Default

There could be many reasons why an administrator would want to perform a factory reset of the IPMI/BMC module. Whatever the reason maybe, knowing the different options and its differences is important.Using ipmitool, we can perform 3 types of resets each with its own implication. Reset BMC Partial factory reset (IPMI and BMC reset but will preserve Network settings) Full factory Default reset (Potential to lose IPMI network settings)Before you execute any of these commands, note the IP_Addr, Net mask and GW IP_Addr for the IPMI. ipmitool lan printUsage note: On VMware ESXi hypervisor, place a leading "/" in front of "ipmitool", for example, "/ipmitool". The executable is located at the top-level root directory.Check out the KB-8123 for detailed instructions.

How to reset nutanix user password in Nutanix Move for Web GUI access?

There are cases where we forget the password for "nutanix" user which is used to login to Move Web GUI console. Nutanix user is a Move app user and not a user on the Move-vm. Therefore, "passwd nutanix" does not work and to reset it we need to follow the manual process mentioned in the below KB article: How to reset nutanix user password in move for Web GUI accessThe procedure mentioned in the above article is to reset the password for "nutanix" user only and not admin (cli) user. Password reset of "admin" who is a user on the move-vm would not be possible as it is the only user exposed on the move-vm. Allowing to reset the "admin" password externally would cause security violations in case of malicious actions. The only way in this case would be to re-deploy the Move appliance. The following documentation includes the step by step process of deploying a new Move VM: Move Deployment
