I’m attempting to import an RVTools into the Sizer tool. I want to exclude some of the VMs before import by editing the RVTools file. When I edit the file and try to import, I get an error “Host cluster cell not found”There are more than 300 VMs, so I can’t import on the VM level and just disable the individual workloads there.Any ideas or methods anyone would suggest to editing the RVTools beforehand? Thanks in advance!
I am having issues editing the scenarios, I’m working on with the below error message: Advanced scenarios can only be edited by Advanced users. Basic users can view the Advanced scenarios in read-only mode.This editing and modifications worked for me last week, not sure what happened.
I tried to use the precheck script on one of our Hyper-V servers.Everything works fine, but I get the error message ".... not a Domain Admin." even though my user is a domain admin. I think this might be related to the fact that the Domain Admins group is called "Domänen-Admins".Has anyone seen something like this before?
I am trying to import Nutanix Collector (latest available version) excel to sizer. The excel contains a large number of “PoweredOff” virtual machines. I want to make the sizing based on performance figures only for “PoweredOn” virtual machines. If I choose “CPU: performance” I get a warning message:“Data being imported contains one or more VMs that were powered ON during the collection period and reported CPU utilization. We recommend you to size both Powered ON & Powered OFF VMs.” The warning it self doesn’t make much sense. Maybe it should read“Data being imported contains one or more VMs that were powered OFF during the collection period and did not report CPU utilization. We recommend you to size both Powered ON & Powered OFF VMs.” Additionally “Upload” button is grayed out and I cannot proceed with the sizing. IMHO the “Upload” button should not be disabled.
Hi everybody,i’m trying to Size a Mine appliance with Veeam (Workload: Mine (v2) with Veeam) leaving all default and with Nutanix Hardware and i get the error below:No Optimal Solution found for following cluster(s) due to:MineModel not supported for standalone backup mineIn order to generate an optimal solution, please try modifying the workload requirements and/or sizing options. You can also try switching the Sizer Policy profile or re-configuring the selected Sizer Policy profile. If i try the same with HYCU it works as expected.Any suggestion?Thank you
Hi! I have two doubts related to Collector´s vcpu and cpu calculation.1) I couldn't find the information on the vcpu/cpu ratio per VM in Collector's Excel spreadsheet? Please, how is it calculated when we perform workload upload per VM? 2) In Sizer, I performed a manual modeling from Collecto´s Excel spreadsheet information as a “Raw Input” and compared it to the automatic per VM-upload modelling.In the analyzed scenario, the customer has 440 CPU Cores distributed in 19 physical servers/hosts in the current environment (vhost table information) My calculations/modelling for a “Raw Input” is the same for the overall resources calculated by the automatic per VM upload (RAM, Datastore), except for the total o CPU cores in the cluster.The automatic per-VM upload/calculation was performed with the following settings: As result, the workload was modeled with 552 CPU cores: Please, why does the per-VM upload have 100 more CPU cores than the existing customer´s environment (552 vs 440 from t
I want to collect informations from a single hyper-V host in a cluster.But i get an error:HTTPSConnectionPool(host='192.168.10.141', port=5986): Max retries exceeded with url: /wsman (Caused by NewConnectionError('<urllib3.connection.VerifiedHTTPSConnection object at 0x000001AD0B88C808>: Failed to establish a new connection: [WinError 10061] No connection could be made because the target machine actively refused it'))Powershell 5.1 is installed, IP is correct. Has someone an idea?
Hello team, We used Nutanix sizer to configure a 3 node cluster, if hybrid mode is selected the smaller suggested option for cold data is a 4 X 2Tb SAS disks set when we choose 2 x 960Gb SSD for hot data. Is it possible to get support and buy a license if we configure the node with 2 x 2Tb disks? It's a small environment and we don't need all that extra space. Every hardware component is in the supported compatibility matrix of the vendor, just not sure Nutanix can fully support a custom configuration
I want to create a configuration in Sizer that takes a snapshot once a day.However, an error message is displayed on Sizer and configuration is not possible."Cluster: 'Cluster-1' nodes with SSD capacity less than 7.68TB are not allowed when configuring Hybrid nodes with RPO of 6 hour and node capacity ranging from >96TB upto 136TB. For more info, refer to Nutanix Maximum Configurations & Snapshot Frequency Field Requirements"Sizer's workload only has Daily Snapshots set."Hourly Snapshot Retained" is unchecked.However, for some reason, the condition check for 6 hours RPO is caught, and the hardware cannot be configured.What should I do to remove this error?
Hi. I’m trying to use Nutanix collector 4.0 to collect Hyper-V sizing information, however the following error message is displayed during the scanning phase:“Bad http response returned from the server. Code: 500. Content”I tried to use it with Remote option and locally on a cluster member and the same happens.Running the precheck script it shows these failures on the picture: The user logged in is a Domain Admin and local admin, however the script returns a failure about the user rights. Does anyone know how can I enable the “Basic auth” stated on the script output?I also tried Collector version 3.5.1 with no success.Any tips?
Mine sizing error - The number of Server Virtualisation VMs in cluster: CLUSTER should not be more than total nodes in the cluster.
Hi, I’m trying to make some changes to a configuration I put together for a customer, in relation to the Mine backup. I am trying to alter any aspect (in particular I’m trying to change the retention to be longer, wtih fewer VM’s) - but each time I try I get the error “ The number of Server Virtualisation VMs in cluster: CLUSTER should not be more than total nodes in the cluster. “ Anyone know what this is please?
Collector 3.5.1, Windows version. The customer has collected the data from a 2-node Hyper-V cluster and I can open the excel and browse through it - it looks right to me, I see all the VMs etc. When I try and import into sizer, I get “Some unknown error occurred”. Any ideas? There’s nothing particularly strange or unusual in the data that I can think of. In the meantime I will probably try and manually add the equivalent workload. Thanks, Allan.
HI, I tried to create DX360 Gen11 8SFF scinario with 2x 4410Y CPU & 7.68TB 2.5 inch Samsung RI ---SSD(P56763-B21), but Sizer shows following message and I can’t save the config:---Due to thermal restrictions on DX360 Gen11 platforms, if 8470Q/6458Q processor is selected, then drive type can't be SAS SSD or NVMe in cluster "Cluster-1". ---I think it should be fixed, or could you please show a workaround?
Hello Team,Hope your are all doing well We need to size a New Nutanix Cluster for Disaster Recovery purposes of an existing cluster (04 x NX-8155-G7 with AHV).Before that, we need to scale the Existing platform by adding more compute ressources to support additionnal workloads. We were able to do it easily : we used a Scenario in Prism Central and added the workloads and clicked on the “Recommend” Button (please see pic below) : Now, we are not able to do the following :Size the additionnal storage related to retention of local snapshots (for the Production Cluster) Size the Cluster of the DR Site : We used Nutanix collector to collect performance of the existing platform and next we exported the Excel Output file and imported it to Nutanix Sizer. We faced from the following :We are not able to inject the additionnal Workloads for the Production cluster We are not able to add the addtionnal storage related to retention of remote snapshots.Please do you have any idea to correctly size
