Nutanix HW compatibility : CISO NEXUS 3064-X and supermicro
Hi folks ! My client asked me a quite though question today : since we are bounded to CISCO Nexus for physical switches, we digged on a low latency nexus with SFP+ connection. It seems that 3064-X is a good choice but as far as I know, Cisco SFP+ compatibility with 3rd party is azardeous. 2 questions : Are there some kind of hardware restriction w/ Nutanix Supermicro stuff appart from SFP+ cable (MOLEX 074752 series as far as I know) ? Is there a compatibility matrix of this granularity level somewhere ? best regards,
Chart from Prism with blank interval
Hi there, I'm facing a problem with Prism that display some weird chart. As you can see above, the chart shows no value (blank) every 6mins. [img]https://d1qy7qyune0vt1.cloudfront.net/nutanix-us/attachment/685iB57C026A9AF18DE6.png[/img] When I go to the analysis page, the blank is still present and there is some strange movement of the Memory line: [img]https://d1qy7qyune0vt1.cloudfront.net/nutanix-us/attachment/686i56E0C99ADEDE0F4A.png[/img] Do you know where this could come from ?
My cluster was looking very nice in Prism (as usual) yesterday but I happened to take a look at my NCC summary output and found that Genesis wasn't running on one of my cvm's. I was able to issue a 'genesis start' command and all was good again but I'm kind of curious if I should expect the Genesis service status to be reported up to Prism. I gather that, without Genesis running, the cvm won't play in any of the cluster reindeer games so its running status seem kind of important to me. Am I wrong in this assumption? And if not, is there some way that I can get an alarm should this happen again (other than running/reviewing NCC)? Thanks in advance.
Nutanix operating in a 'private' cluster (feature workarounds)
Hello, In setting up Nutanix we do not allow it on the Internet. How much does this constrain what we can do with it? ie Life Cycle Management (LCM) Although LCM allows us to point to a different source we will still need to get the Modules somehow? Although LCM lets us start an Inventory it still seems to want to go out and get a Manifest file and then it fails? Can these be downloaded somehow? Where else are we going to find difficulty with? Thank you...
3 node cluster design for 6000 series nodes
I'm putting together a design for a 3 node cluster with the 6000 series nodes. The first block is 6235-G4, the second block, I'm a bit confused. I could get another identicle block with 1 node ( 6135-G4), but there is also the option of getting a 6135C, which is single socket, less RAM, smaller SSD and crappier CPU. It's cheaper and will make the min 3 node cluster, but I'm wondering what kind of performance hit it will have for the overall solution. Am I better off getting a 6135-G4 and being done with it?
NGT on *server name* Should be upgraded Error
I have about 9 VM that have this error (all 130 other VMS are fine). The VMS are either Server 2012 R2 or server 2016. I have tried manually mounting NGT CD from the manage guest tools on the Nutanix VM page, then I launch the console and try to install NGT. I run the mounted cd and NGT fails saying that NGT is already installed. I’ve tried uninstalling NGT and reinstalling it from the mounted CD, but it’s not installing the latest version. How can I update NGT on these 9 VMs?
Guidelines regarding application consistent snapshot
In modern IT Infrastructure, data is critical and having a copy of your data from where you can recover from has become an important pre-requisite for system design. To achieve this we use a technology known as Snapshot.So is it possible to even save your system running state while taking a snapshot in Nutanix environment?Absolutely YesIn Nutanix, we provide a technology known as application-consistent snapshot which can be selected when configuring Data Protection Domain.Want to know more about Data Protection with Prism elementGive the following article a readData Protection Guide So Nutanix have some guidelines with regards to Application consistent Snapshot?Absolutely yesNutanix recommends installing NGT on the VMs. Microsoft VSS service should be enabled. The workload running must be able to support to quiesce I/O operations. You must configure one consistency group for each VM. For the protection of VAAI clones with application consistency, each VAAI clone should be in its own pr
Is it possible to deploy Nutanix nodes without Foundations Tools?
Hi, I am new here and this is my firts experience with Nutanix. I need to deploy 3 nodes, and I’ m going to use the native Hypervisor from Nutanix (AHV). I saw a video explainning that, to do it, it’s necessary to download and use the Foundation Tools to configure the cluster and than, gathering access to PRISM. Unfortunally, I can’t download Foundation, due to the Nutanix blocks were registered by our customer (message: ...The email XXXXXXX is not authorized for the account associated with the serial number YYYYYYY) and we don’t know who did it. We are trying to identify who registered the blocks but, meanwhile, Is there another way to deploy it without the Foundation tool, or is there a way to unregister the blocks and register again but to different user account? Thanks in advance,
Slow logon to Prism interface after upgrade to 220.127.116.11
Hi, We have recently upgraded our Nutanix cluster from 4.0.3 to 18.104.22.168 and are noticing slower logons to the Prism interface. Before the upgrade this was almost instant while now it might take up to 10 seconds. Has anyone had the same experience?
not showing option to format disk
Hi, We have setup in pri production stage. Cluster is having 2 x 800 GB disk & 2 x 6 TB disk on each node. Cluster is having 3 nodes. We removed single disk from one host & after 10 min. we reinserted disk in same slot. Now cluster is showing 11 disk & not allowing us to format disk which is reinserted. How to add this disk to current cluster? Thanks in advance. Vivek
Import VM from KVM on Acropolis 4.5
I need to import from KVM (CentOS 6.6) on Acropolis 4.5 a VM RedHat 4.4 with ide disks (RH 4.4 doesn't support Virtio). I have created a new VM from acli with IDE disk:acli vm.disk_create TEST_RH44create_size=80G container=cnt1 bus=ideacli vm.nic_create TEST_RH44 network=vlan.0. Now I have to import the source VM disk image (ASdisk01.img), How to import it as ide on the new VM on Nutanix?

Errormessage about disabled VM autostartup & vSphere HA cluster
Hey guys, We are busy building a Nutanix 22.214.171.124 infrastructure with vSphere 5.5. We have six nodes in two blocks, and the design consists of 2 Nutanix clusters with each its own vSphere cluster. HA is enabled on each cluster. We are getting an error on both Nutanix clusters in PRISM UI: [i]Virtual Machine auto start is disabled on the hypervisor of Controller VM [/i] Nutanix best practices recommend to enable "Start and Stop Virtual Machines with the system" on each host, and move the Nutanix CVM startup to Automatic startup. But, according to This VMware KB the automatic startup feature is disabled when moving an ESXi host in an HA enabled cluster. Just like the error message says. Is this expected behavior? Can this error message be disabled because it is just not valid in combination with VMware HA enabled clusters? Or is this still a configuration error?
How to avoid Self Service Restore icon when feature is not enabled
AOS is in 5.10.8, We need to install NGT on Windows Server 2016 with only VSS feature enabled and not SSR. However, after installation, even though the SSR feature is not enabled, there is the SSR icon on the desktop. It can be opened and bring us to “http://localhost:5000”. I can understand that the feature is not active but I would like to avoid having it displayed on the desktop. How to avoid to have this on the desktop ? (I’m looking for another way than deleting the icon manually after NGT installation). What about this local web server ? Could it be stopped ?
Combining a mixed hypervisor cluster with mixed hardware
We have a 4 node cluster configured as follows:2 x Lenovo HX1320 (dual 8-core Xeon Silver 4110 CPU @ 2.10 Ghz / 192 GB RAM / 7.11 TB storage) with ESXi2 x Lenovo HX5520-C (single -core Xeon Silver 4110 CPU @ 2.10 Ghz / 64 GB RAM / 35.83 TB) with AHVWe would like to convert the ESXi nodes to AHV. Looking at the knowledge base and the community it seems like doing this would allow all 4 nodes to share the virtual machine load and because the CPUs are the same we should not have to worry about compatibility issues. Is this a correct assumption? Any issues we should watch for?
Active Directory configuration fails with "Directory config name is invalid"
I cannot seem to get Active Directory authentication configured and cannot figure out why. After following the directions in the support article "Configuring Authentication" I receive the message "Directory config name is invalid". Here is what I have tried: using the IP rather than the host name, turning off the firewall on the DC, using a different AD host, trying different ports (i.e. 389 and 3268), trying a different browser (firefox and IE), specifying the full directory path (/ou=,dc=,dc=) - nothing seems to work. I just keep getting the error message "Directory config name is invalid". I can ping the DC host from the CVM using the FQDN; firewall issues have been ruled out by turning off the firewall; the LDAP url is typed correctly. My thought is that this feature simply isn't working correctly on 4.1.3. Has anyone else experienced problems getting AD configured properly?
Question on Local disk vs NFS Datastore
A rather simple question :) Once the NFS Datastore has been presented to the nodes, each node shows the NFS Datastore and the Local disk as available storage. My question is, how do others deal with this scenario? What is to stop an admin from storing data to the local data store as opposed to the NFS data store which is where you want them to store their VM's? Curious how others have dealt with this. Thanks, Sky
First time using vmware upgrade manager on cluster
Just had the cluster installed. I'm going to patch my 5.5 installs, I put the first node into maintance mode and its just waiting for the CVM to power off or move. Should the CVM shutdown on its own or do I need to power it off before I patch and reboot? thanks,jb
Vmotion and ESXi MGMT VLANS are different, CVM should have which VLAN?
Hello All, One of our customers decided to have Vmotion and ESXi MGMT on different VLANS and they will split the 10G connections. So for this kind of setup, which VLAN should CVM be in? Do you have any recommendations? Thank you so much...
ECX error & disk id & svmotion
Hello Folks, I`m busy installing a 6 node cluster, some errors or doubt comes out along. my environment : 3 block, 6 nodes (2 nodes/block) AOS 4.6.2 一. When I create a new container, make the Enable Erasure coding button checked, error pops up"enable EC-X will break the current block awareness !" seems mean ECX will disable block level awareness ? 二. As many of us know, if need locate the physical slot location of a disk, you can simply led on that drive. but there is possibility led on function inaccurate or disabled, in this scenario, you must locate the disk by disk id rule, e.g shelf id.slot/bay ID, but the DISK ID in prism hardware section seems ramdom/ruleless number, I can`t locate physical location for a disk. 三. When I do the test about removing a node from nutanix cluster, A doubt appears: Do I need or is it the best practice to execute storage vmotion(other then only vmotion vm`s ) before removing the node ? I think the diffecrence of two methods is who is the data mov
IPMI Ports Show "No Connect" In BIOS
Hello, A few of the IPMI ports on a new installation (3K and 6K series) show "no connect" in the BIOS. The ones that are working show "Dedicated LAN." Our networking folks have verified the ports as access ports, and are active with the correct VLAN ID configured. We will be swapping the ports on the switch between the working/non-working IPMI ports to confirm if the issue is on the switch or node side. Could there be some BIOS settings we may have missed? Any thoughts would be greatly appreciated. Thank you.
