Question about KB-1451

Hello technical leaders,Yesterday, I recieved the letter about KB-14514. It is HP firmware issue.There is,---------------HPE DX380/DX360 G10 Plus: Filesystem Errors and I/O errors on a hypervisor boot volume・Identification:The node is HPE DX380 G10 Plus FSC or HPE DX380 G10 Plus. It may have different number of drives such as 12, 24, etc. Has HBA controller HPE-NS204i-x-Gen10-Boot-Controller. HPE-NS204i-p-Gen10+ Boot-Controller with part number P12965-B21 or HPE-NS20i-r-Gen10+ Boot-Controller with part number P26463-B21.The host in most instances will be unreachable via SSH and not allow console logins.Filesystem inode errors and potentially other filesystem errors will be displayed on the IPMI console. Please note you may not see this on ESXi.The boot drives in the RAID report S.M.A.R.T status as PASSED/OK HPE iLO console for the host may show I/O errors as per the screenshot.---------------We have HPE DX380 G10 Plus and use HPE-NS204i-x-Gen10-Boot-Controller.I have a question.

Has anyone used Mikrotik switching for a Nutanix cluster?

Subject says most of it. I have read the physical networking “best practices” guide, and I am currently running a small (3-node, NX-1175S-G7) cluster on top of Dell S4112F switches.My org is looking to add a second cluster at a second datacenter, and I was asked if the Mikrotik CRS510-8XS-2XQ-IN or Mikrotik CRS518-16XS-2XQ switches would work for the new cluster.My initial response was “no,” but I’m wondering if anybody has tried it? I would be concerned about buffer size on the switches… but how much does that matter if all of the cluster nodes are connected at the same speed, and I have a L3 boundary (router/firewall) between the VM subnet and the rest of the network (router has much better buffering than any switch would)?I do not have decision-making power here, so how can I “influence” my boss that using three-figure switches is likely to be a problem for a 5-figure+ cluster?

Regarding the pagination not working for v3 hosts endpoint of Prism Central

For our development work, we are using /v3/hosts/list endpoint. As per the specs, we want to use length and offset for pagination to fetch large number of hosts. We tried using it as follows:curl --location --request POST 'https://<host>:9440/api/nutanix/v3/hosts/list' \--header 'accept: application/json' \--header 'Content-Type: application/json' \--header 'Authorization: Basic abc' \--data-raw '{ "kind": "host", "length": 1, "offset": 9}'However, length and offset params doesn’t seem to be working. It returns all the hosts (2 in our case) irrespective of the params passed.  Also, we used the same params in /v3/vms/list and they are working as expected. So, wanted to know if this is expected or is this an open issue? Is there a way to get all the hosts through Prism Central (v3) APIs?

Nutanix Support for acquired environment

Hi there community, I’m hoping that someone can give me some guidance. We recently acquired a facility with some Nutanix clusters deployed, and this is my first time working with Nutanix. I have access to the vSphere hosts but no idea on the Nutanix side of things. Trying to activate the support portal with any and all serial numbers I can find just gives me an invalid serial number message….which means I can’t open a support ticket to ask about the serial numbers. I see each of the host machines running a Nutanix Controller VM, but I’m guessing there is a central management console tied to the hardware (NX?), and a spreadsheet from the seller lists some hardware/enclosure serial numbers, but under serial number just mentions refer to PRISM. I’m trying to hunt down someone at the seller to provide more details and make sure things get transferred, but is there anything I can do or look at in the meantime to figure this thing out?

Prism central 2023.3 NTP and DNS

I recently tried to deploy prism central 2023.3 by uploading the binary and metadata, but I couldn't deploy it because the customer didn't have dns and ntp, and also didn't need the microservices. There is a way to deploy it without it?

Automating CLI commands

I’m looking into setting up an automated task to get the output ofacli snapshot.listfrom each of our clusters, so we can track down forgotten snapshots & which VMs they’re on.Ideally this would run from nutanix itself and spit out the results into some kind of shared storage space we can review, but according to this thread, non-default cron jobs are deleted when AOS gets upgraded. I also can’t see anything in PC/PE to automate this, or find this information without SSHing into the CVMs.At this point, I’m looking into writing a script to host somewhere internally that SSHs into each set of CVMs and runs the command, but then I’ve got to handle password security and frankly it seems like too much of a bother for something I’d only have running monthly at most, that would take me 10 minutes to handle manually (if I remember) Does anyone know of a way to achieve this, or shall I just throw some reminders on my calendar?

DMZ cinfiguratuin

Hi,I have configured a 3 node nutanix cluster with an active active lacp configuration. We have 2 more ports on the node which we wanted to use for dmz. However the prism element gui configuration fails continuously. I tried removing the 2 ports from the br0 bridge and add to br1 bridge. Doing so is only supported in one node, on the other nodes it is not reflected. Kindly suggest the right method or commands to configure since none of them seem to work. Also whether is there a separate vs switch configuration is needed for the scenario? Ps: I don't have flow or prism central. And since it is in deployment state, license activation is also not done

Expand Cluster with New Node

Dears, we are planning to expand a cluster consists of 3 Nodes, the new node supposed to come with DiscoveryOS the Existing AHV and CVM are using tagged VLAN, could you please advice if using expand option from the prism element will be able to discover the new node and re-image it ? should any preparation be done on the node before the expanding  AOS version is 6.5.4, foundation is 5.4, IPV6 is enabled on the switch. from Prism webUI guide i can see “If the Controller VMs in the cluster reside in a VLAN configured network, the discovery process still finds any factory-prepared nodes regardless of their current VLAN status (configured or not configured).” → in our case it’s coming with DiscoveryOS.

Data service IP vs direct attach when connecting Volumes

When I searched the documentation, it was said that scsi-3 pr3 is supported when attaching volume from AOS 5.17.my curiosity1. In versions prior to 5.17, when allocating a shared volume for vm redundancy configuration, if you use Attach instead of using iscsi-initiator, does it not work?2. Considering I/O speed and stability, which do you think is better, mounting a volume through iscsi-initiator or connecting to a VM as a direct attach?

Convert AHV disks to SCSI in Windows 2013 post-MOVE migration?

Hi,I followed instructions to migrate a Windows 2013 server from ESX to AHV successfully according using Nx MOVE to https://www.vmwaremine.com/2019/01/24/migrate-windows-2003-x86-to-nutanix-ahv/#sthash.8hpeCflP.T3i44mTW.dpbs, it works great by the way. Now… In the process SCSI disks are cloned to IDE and the Windows 2013 SCSI controller is not recognized.  In this scenario, Is it possible to reconvert those disks back to SCSI? I guess I need to get the driver first (Fedora?) and follow available procedure to reconvert, Has anyone done this? Thanks!

New - where do we start.

Hi. So our nutanix system is arriving in a few days, it’s now in the country.  I’m going onsite in mid January to set it up where do I begin.  We are going to be using Acropolis (excuse the spelling if wrong). From what I gather i’m just going to have rather a lot of boxes around 95kg in total, I guess once i’ve worked out how to put the hardware together where the heck do i begin getting acropolis installed on it all, I possibly just missed it but was expecting an easier Idiots guide this is where you start with your new system. We are going to be setting up various windows servers when we get to that stage.  I’m ok with VMWare but never used Nutanix before. I might be in the wrong forum dumped it in AHV Virtualisation as i’m assuming that’s Acropolis.  That’s how new  I am :) Cheers EDIT: Only just thought i guess i should wait till i see the kit it might come with a start here guide.
