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.

The CVMs that comprise a Nutanix cluster get their time by syncing to a single member which is known as the NTP Leader (aka Genesis Master). This node will be responsible for syncing with whatever NTP servers the customer added to Prism. When NTP is properly configured, the Leader CVM will set its own clock to the time provided by the server and then all other CVMs will sync with the Leader's time.  For AHV clusters, the same list of servers used by the NTP Leader will be configured on each host to sync with independently. All other hypervisors need to have NTP configured separately using their unique management tools. By default User VMs sync their time with the local hypervisor where they are running, but users can configure their machines to sync with local or internet-based NTP servers as well. Importance of NTP: If there is a power outage and cvm’s pick up wrong time it can prevent the cluster to start It’s very difficult if you're trying to RCA any issue Commands:To check ntp s

 Can't I remove the interface included in the bond with ovs-vsctl For example If br0 contains interfaces eth0 to 3 in bond name br0-up, I want to clear eth0, eth1. If I can't, is there a command to update or remove interfaces like manage_ovs --bridge_name br0 --bond_name br0-up --interfaces eth2,eth4 update_uplinks command in ahv? Thank you for always helping me

I don’t see anywhere to acknowledge or remove this alert, it is no longer an issue and we resolved what was causing the issue but it keeps showing that we have a critical alert for the 28th.

Before you begin Before you decide to change the CVM, hypervisor host, and IPMI IP addresses, consider the possibility of incorporating the existing IP address schema into the new infrastructure by reconfiguring your routers and switches instead of Nutanix nodes and CVMs. If that is not possible and you must change the IP addresses of CVMs and hypervisor hosts, proceed with the procedure described in this document. Guest VM downtime is necessary for this change, because the Nutanix cluster must be in a stopped state. Therefore, plan the guest VM downtime accordingly. Verify if your cluster is using the network segmentation feature.nutanix@cvm$ network_segment_statusNote the following if you are using the network segmentation feature. The network segmentation feature enables the backplane network for CVMs in your cluster (eth2 interface). The backplane network is always a non-routable subnet and/or VLAN that is distinct from the one which is used by the external interfaces (eth0)

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

Can anyone let me know the release date of the LCM Framework  version 2.3.3 ?

We have to do a deployment of 5 HPE DX nodes with AHV as hypervisor. Is it mandatory to have the iLO ip address in the same subnet as CVM & Host ? If not then do we have to give 2 IP addresses to foundation VM ? Let me know if anything else is needed.

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

In our environment, eth2,3,4,5 is assigned to br0. The bonding policy uses active-backup and the current active interface is eth2.I want to leave only eth2,3 in br0 with the following command while the cluster is online.allssh manage_ovs --bridge_name br0 --bond_name br0-up --interfaces eth2,eth3 update_uplinks1. Is it possible to proceed without stopping the cluster?2. What if I need to stop the cluster?

Can you imagine performing firmware upgrades manually?Checking compatibility matrix for each component, procuring ISOs and staging them, take days to perform firmware upgrade and one can only hope that the host/cluster is still functioning after everything is said and done.LCM simplifies Nutanix IT infrastructure life cycle operations by consolidating software and firmware component upgrades into a unified control plane. LCM does all the hard work of managing all the upgrade dependencies for the software and firmware components. You don't have to worry about a thing. LCM normalizes firmware upgrades across hardware platforms and provides a single unified process regardless of vendor. Based on the bundle of components -- software and firmware-- that are selected for upgrade, LCM creates a plan that ensures the updates are deployed with the minimal number of service or host restarts.Get Started: Use Prism Central or Prism Element to open LCM Perform the LCM inventory (default is set to

Did you know that many of the health checks and alerts within Prism can be configured according to alert policies?Though it is usually a good idea to leave alert configurations at their default values, some alerts (or checks) can be adjusted to accommodate particular needs through an associated alert policy. For example, if there is a known condition within an environment in which an associated alert goes purposefully and perpetually ignored or overlooked, the associated health check can simply be turned off.Alerts can also be enabled/disabled based upon a particular severity level (i.e. Info, Warning or Critical). Also, even better than outright disabling an alert or check, some alert policies can be configured for auto-resolution if the condition has not recurred within the proceeding 48 hours of its initial exhibition.More information regarding the configuration of checks and alerts can be found within the Configuring Health Checks section of the Prism Web Console Guide.

Hello NX, I have a question, is it okay if i will disable the SSL port of my Nutanix CVM's and management port? Because if shows vulnaribility into the scan. What would be the effect if i will disable those ports.. Thank you.

Dear Team,My cluster is out of storage now,I have one Lenevo SAN Storage(V3700).can you please suggest how to utilize this storage with Nutanix AHV cluster. 

Hello everyone. I want to allocate IP to the cloned VM using sysprep through the blog address below.https://www.nutanix.dev/2020/02/06/customizing-ahv-vms/ However, the IP is not changed through the script in the blog.In addition, it was confirmed that the host name and password were changed. The versions I am testing are windows 10, windows server 2016. Please, let me know. Thanks,Regards

This is the scenario I have:We have a four node cluster running Hyper-V. We want to migrate/reload/replace with AHV. There is nothing on this cluster that needs to be preserved.I tried the Foundation Portable application, but it does not seem to discover the nodes. I suspect that is because they are neither bare-metal nor factory imaged at this point. (based on this article - https://portal.nutanix.com/page/documents/details?targetId=Field-Installation-Guide-v4_5:Field-Installation-Guide-v4_5)This is a “retail” cluster, so I do have support. I just don’t know if it’s appropriate to tie up a support engineer for the time it would take to reload a cluster. So I was hoping to at least get started on my own. I did some googling and searching here and the KB. But I suspect my search terms are either too broad or maybe even far too specific. All I get back is how to setup a brand new cluster. 

In AOS 5.0, you can expand the disk online. In versions older than AOS 5.0, you needed to go offline to expand the disk and then online again. But before expanding the disk you will need to increase the size of the volume group. The size the disk in a volume group can be increased using the Prism GUI or the aCLI or nCLI. This article describes the increasing the size of the volume group disk using nCLI and aCLI and also shows how to expand the disk online in Windows guest OS. Expand disk size of Volume Group through aCLI and nCLIFrom aCLI:Starting from AOS 5.x, the disk can be expanded without taking it offline.Increase the size of the disk:nutanix@cvm$ acli vg.disk_update <Volume Group name> <disk index> new_size=<size of disk>Note:  when specifying the size, uppercase G is for gibibyte, lowercase g is for gigabyte.From within aCLI, execute "help <command>" to get more information about commands, including optional arguments. From nCLI:Increase the size of the

Recently, we upgraded AOS and AHV in a 6-NX-1065-G5 nodes cluster. Those nodes have only 1 Gbps interfaces and the upgrade process got stuck many times while actively moving guest VMS to other nodes when setting each node to maintenance mode. Tech support told us this happened because new AOS and AHV versions were designed to work at 10 Gbps, which we know is a best practice, but a hardware upgrade would be needed in our scenario then.Question: I´m guessing configuring the four uplink interfaces as Balance-SLB bond may help, having a total bandwidth of 4 Gbps in optimal conditions, Has anybody gone through this problem and applied this cure? Was it useful or… Not enough? Thanks in advance
