Would I be able to create storage containers in my cluster for the purpose of "pinning" VMs only to hosts that are assigned to the containers - restricting VMs to the hosts that belong to the container? The need is to control VM migration during Software Upgrades due to multicasting issues with the hosts.
Nutanix CE installs but CVM does not create cluster
Hi,I followed this guide:Installing Nutanix Community Edition (CE) on vSphere 7 - Derek Seaman's IT BlogTo test a install of AHV/Prism CE and the AHV host installs fine but the CVM can not get to the outside world or ping ip’s.I can ssh to the CVM from the host on the correct IP and do the one_node_cluster create command but it just fails with `Failed to reach a node where Genesis is up` if I do `genesis start` it gets past that but just hangs after it starts up some services during the create.I tried not checking the one_node_cluster option in the install and doing it manually afterwards, but I get the same results.Happy to provide any info. The gateway etc look fine in the `/etc/sysconfig/network-scripts/ifcfg-eth0` file
ESXi - Storage Containers/Datastores and vMotion Operation Limits
We are planning a major migration from existing 3-tier ESXi over to Nutanix/ESXi (AHV to come later). Due to time constraints in our move, we are trying to optimize how many VM's can migrate at one time. VMware has a few well-known limits on their operations: vMotion operations per host (10Gb/s network) - 8 vMotion operations per datastore - 128 Storage vMotion operations per host - 2 Storage vMotion operations per datastore - 8 If I take a "one storage container to rule them all" approach, I will be limited to 8 migrations at once, as long as I spread out my migrations to 4 hosts. My target will be a 14 node cluster, so I would like to push up to 28 operations, if at all possible. Would it be considered a best-practice to carve out 4 storage containers, knowing I'm still in the same pool, and fan out the migrations to get around these limits? My goal is to saturate my 10Gbit inter-datacenter link. Yes, I like to push the limits (break things?). Would the multi-data
Units used in Replication Throttling?
Hi, We want to throttle replication bandwidth. In the Remote Site config in Data Protection, the option is to throttle B/W in MBps. Is this Mbps (megabits per second) or MB/s (Megabytes per second)? The unit implies megabytes per second (i.e. the "B" is capitalised), but that is normally a unit of throughput not bandwidth... Obviously there is an order of magnitude in difference so its important we interpret this correctly!
How to Clear nCLI history on CVM
I've been trying to clear out a entry in the nCLI interface on a CVM without luck. tried the standard 'history -c' and 'events history clear'. Basically I have a value I dont want to show up at the propmt is a user is cycling through the "up arrow history" while in ncli. Anyone with the command?
vCenter Server Appliance upgrade (6.7 to 7.0)
The upgrade process for the VCSA from a major release to another is as follows:A new VCSA with a temp IP is created in the vSphere host/cluster by the upgrade process. The upgrade process migrates the config/data from the old VCSA to the new one. The Old VCSA is shutdown and the new VCSA is renamed/re-ip with the values of the old VCSA. New VCSA is then rebooted.At this point the new VCSA should have the old VCSA name and IP address. My question for those that have done this already is, how does the Nutanix cluster Prism element reacts to this in regards to its vcenter registration? Will all this be transparent to it or will it see the new VCSA as a new device and create a duplicate entry? I assume the migration process will copy SSH keys and certs from the old VCSA to the new one so Prism won’t bat an eye, but I just wanted to confirm.
if nutanix have its own replication method to dr site what is the use of vmware srm.?
hi, in the vsphere administrative guide its mentioned to use vmware SRM along with nutanix SRA for the remote replication.if nutanix have its own replication method what is the significance of SRM? Thanks in adance. RGDS rj
Data-At-Rest-encryption | Configuring and Verification
Security and encryption are backbone of an IT infrastructure. Many organisation have made it a compliance to encrypt data and keep the data on-prem. Nutanix also provides industry standard security features. One of them being :DATA-AT-REST ENCRYPTION Nutanix provides an option to secure data while it is at rest using either self-encrypted drives or software-only encryption and key-based access management (cluster's native or external KMS for software-only encryption). Want to more about D-A-R-E and it’s features? Go through the following guide D-A-R-E guide During various compliance auditing and administrator task, we need to verify if D-A-R-E is enabled and successfully working or we need to configure D-A-R-E How can we safely accomplish that? We have different methods using which you can verify that D-A-R-E is enabled or not . You can use these methods to automate the process of verification or configuration. Go through the following KB to know about the various methods with comm
Protection domain cannot be activated or migrated
Good day Nutants I got a situation that I'd really appreciate your help in resolving After successfully migrating a PD to a remote site and successfully powering on the VM at the remote site, when I attempt to Migrate the PD back to the Main(Prod) Site it fails with error : critical Protection Domain XXXXXXX activate/deactivate failed and cause is listed as "Protection domain cannot be activated or migrated" Any pointers?? This PD has one CG with one VM in it (WIN SERVER 2012 with NGT installed and NGA service is running)

NX-6260 ( NX-6060 - Part 422-NX-6260 ) Power Specifications
Hello - Can someone reply with the complete power specifications for the Nutanix NX-6260 ( NX-6060 )? I know these have dual power supplies. Please provide the following at minimum: 1.) Voltage of each power supply - I think these are 208V Single Phase 2.) Amps per power supply 3.) Watts per powerr supply 4.) Power Cable Ends - Please confirm - I think these are C13/C14 for each power supply. We do not yet have the boxes so I need to prepare for the power requirements of these devices. I am looking at two of the Tripp-Lite PDU Basic 208V/240V 30A C13 10 Outlet L6-30P Horizontal 1U - MFG Part #: PDUH30HV Also wondering what others are using. Thank You. Sam
How to install and configure CDF trace tool on studio VM?
Citrix Diagnostic Facility (CDF)CDF collects and traces the messages generated by various Citrix services running on the Delivery Controller.

Active Directory Domain Contoller(s) or DNS servers configured on the UVMs in the cluster
Hello,My client has this alert "Active Directory Domain Contoller(s) or DNS servers configured on the UVMs in the cluster" due the fact that he moved his domain controller on the nutanix cluster. His environment is 100% Hyper-V, and he is totally aware that SMB3 share of the nutanix cluster, requires authentication from the domain. In order to avoid that my client created ISCSI volumes and presented them to his Hyper-V environment, on which he moved his domain controller, trying to avoid that type of failure if everything goes down after a power failure and when everything comes up, the domain controller to be able to boot prior of the authentication.Please let us know what's the best approach for this matter and what's your recommendation for this kind of setup, especially when all the domain controllers are virtualized.Regards,Adrian
Transferring VM virtual disks into AHV - freedom of choice with Nutanix
When it comes to migrating your environment into AHV the recommended way would be to use Nutanix Move. Much being said and written and more is coming. Nutanix understand however that using Move may not be an option for whatever reason. Freedom of choice is important after all, right? In case you are looking for an alternative way to migrate your VMs’ disks into AHV then keep reading.The article referred to in this post covers three scenarios:Source virtual disk files can be accessed directly by the Acropolis cluster over NFS (or HTTP). This scenario is generally possible when: The source environment is a Nutanix ESXi cluster. The source environment is a Nutanix Hyper-V cluster. The virtual disk files are hosted on an NFS server and the Acropolis cluster can be provided access to the NFS server export. (Common in non-Nutanix NFS based ESXi environments.) Previously exported virtual disk files are hosted by any NFS or HTTP server and the Acropolis cluster has access to them. Source vi
