Genesis alarm

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.

Errormessage about disabled VM autostartup & vSphere HA cluster

Hey guys, We are busy building a Nutanix 3.5.3.1 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?

Repost:Communication trouble of CVM when building CE on Nested ESXi

# On March 4, I posted the following but I have written the wrong answer myself, and the status of that bank has become "solved". # Actually it remains unresolved.

Xpress Configuration Scenario

Hi, I apologize in advance for the long post !!!! From the information I've reviewed, the Xpress Models (I'm looking at Lenovo's offering) will support a maximum of 4 nodes. In addition there is no Protection Domain. Let's pretend that I'm a cloud provider for multiple customers, and I host their (Domain/File/Print/Email/Sql) servers in my 4 node domain. I want to use an (Acronis/Storagecraft) in VM backup software. These products store their backup images to a NAS/Share. If I setup a second 3 node Xpress Model that is storage "heavy" running Acropolis File Services, as a NAS/Share destination for my backup images, is there any restriction that you can think of that would prevent/limit me from doing this ? Right now we use StorageCraft and save to a Windows Storage NAS that has RAID 10 and I'm concerned that writing to will not be able to handle the I/O? I'm guessing that the 3 node Xpress AFS will easily handle intensive I/O writes. On weekends, the Full backup runs a

Is ESXi 6.7 U3 supported on Nutanix cluster 5.10.X and later?

For a nutanix cluster to be able to install a newly released hypervisor, the information about it must be already in iso_whitelist file.  This file can be downloaded from Nutanix portal (search for ESXi 6.7 U3) and is required when installing/upgrading hyperviosr using prism one-click.ESXi 6.7 U3 (built number 14320388),  has been out as of Aug, 20, 2019. It is Nutanix policy to support newly release hypervisors within 90 days after they are release by the hyperviosr vendors.As of this writing (Nov 18, 2019), nutanix has released the iso file for this release and is supporting installation of this built on Nutanix clusters 5.10..6 and above.Below is a public KB regarding the support for this release:https://portal.nutanix.com/#/page/kbs/details?targetId=kA00e000000CsgLCAS

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,

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?

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

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?

What's the behavior when the Nutanix node local storage is not enough for data of local VM?

Hi All, According to my material on hand that Nutanix will keep a copy in local storage for local data required. So if there are some storage intensive VMs running in one node and the local storage in that node is not enough for data of all local VM, some data should still need to be retrieved in remote node? would like to know the exact behavior. And one more question for DR. If I use vsphere, I still need to buy SRM license or SRM is optional (e.g. for some dedicated features?). For Hyper-V, since the DR feature of Hyper-V is not as rich as VM, can we still use the "Protect Domain" feature in Nutanix for DR in Hyper-V? Thanks a lot in advance! Best Regards, Teru Lei

Enable RDMA on new nodes

Hey everyone - we have 2 brand new nodes that need to be added to an existing cluster.  We enabled RDMA when we ran Foundation on that cluster and now need to add 2 additional nodes.  Do we run the script to choose which card to enable RDMA on before we add to the cluster?  Just looking for guidance on the correct way to ensure it is enabled on the new nodes as well. Thanks!

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

Is your Hypervisor supported by Nutanix

Let say for example you're running ESXi 6.5 U1 and want to upgrade to the latest ESXi version but confused whether the current hardware and AOS will support the latest ESXi version.Nutanix gives you a feature to identify the compatability of different Hypervisors with NX environment easily using the Compatibility Matrix. You just need to visit the compatibility matrix page, filter by using your hardware and AOS and you will see the hypervisors which are supported.Still confused before the hypervisor upgrade?Refer the following document regarding general guidelines before the hypervisor upgrade.Hypervisor-upgrade-guidelines

Storage Node - disk utilization

We added a couple of storage nodes to a modest 3-node cluster that was running out of disk space. The alerts about running out of storage, and not having enough for redundancy, are gone. A few months in, and every time I look in Prism, under Hardware, I see that the storage nodes' "Total Disk Usage" has not gone up very much. The compute nodes' disk usage is about 5-6 times as much as the storage nodes (and the compute nodes actually have more storage onboard than the storage nodes). I understand that Nutanix tries to keep a VM's storage on the same host that provides its compute resources (and the copy is sharded and spread out among other nodes). Is that why I am seeing so little utilisation of the new storage nodes in Prism?

Setting up and troubleshooting remote authentication LDAP/AD

Remote authentication is one of those things that once set up correctly just work. We do not notice it, we simply put in our credentials and use it.It takes some understanding and a tiny bit of thinking ahead when mapping AOS roles and permissions to LDAP/AD users and user groups.So where to start?First, follow Prism Element Security Guide: Configuring Authentication to set up remote authentication.Run NCC Health Check: ldap_config_check.For any issues leverage KBs:KB-2066 Unable to Log In to the Prism web console using Group LDAP authenticationKB-3363 Prism: Troubleshooting LDAP Issues for Prism Log On For those of you PowerShell fans there is a little bit of CLI available:PowerShell Cmdlets Reference: LDAPConnection PowerShell Cmdlets Reference: Domain
