How It works

As part of the Nutanix Smart Support, information about dispatches can now be viewed directly from Portal. With this view, you can edit Shipping, Contact, or FE work address details if necessary.Additional information such as the Part Type, Quantity, Part Location/Component Slot are all viewed from the same pane.If you need more clarification on the dispatch specifically, a Comment option is in place to reach out to Nutanix Support directly. These comments will also be placed in the case notes to look back at if necessary.For more information about the dispatch view, take a look at Dispatches Summary View on the Support Portal.

There are times, when we need to move a vm disk to a different container on the same AHV Cluster.For e.g. : We may want to move this VM Disk on a container with De-Dupliction Disabled. To relocate a virtual machine’s disk to a different container on the same AHV cluster, following steps are required:Requirements for the Move:Source Container ID (where the vmdisk is located originally) Destination Container ID (our target container on the same cluster) VM Disk(s) UUID (UUID of each disk we need to move “acli vm.get <vm-name>”) Power-off the VMSummary of Steps:Determine the vmdisk_uuid of each virtual disk on the VM. Make sure the VM for which the VMdisk we are migrating is powered off. Use the Acropolis Image Service to clone the source Virtual Disk(s) into Image(s) on the target container. Attach the disk from the Acropolis Image(s) which created in Step 3 to the VM. Remove the VM disk that is hosted on the original container Optional: Remove the cloned VMdisk from image services

The storage usage reaches 95% and some windows VM (2016 2019)down.AHV hypervisor 20170830.395After release the disk space many VMs should be repaired.Questions:AHV will shut down VM when the capacity reaches 95% ?  If user reboot VM when it is 95% , will it make  the VM data disks crashed ?

Did you know that Nutanix now has a Smart Support diagnostics collection feature available in Nutanix Support Portal which can directly initiate log collection on Nutanix clusters thereby avoiding the need to manually collect and upload logs to the case?Customers can create a diagnostics collection for any of their clusters on demand. A diagnostics collection is a set of logs and health checks collected in a cluster for a specified interval. They are resources used to monitor the health of the clusters and analyze issues when problems occur. For details on how to create a new diagnostics collection via Nutanix Support Portal, see Creating a Collection section in Nutanix Support Portal. 

We have Nutanix SX-1065-G5 with 3 nodes, every node have 4*16GB, and we need to add 64GB to every node. Is it possible to add 4*16GB for every node ?RAM : C-MEM-16GB-DDR4-2400

ESXTOP can be very good to tool to see the live stats and usage of the Physical host and its components, but more often than not, we would like to use that data to plot graphs or even save the data to examine it later. This brings us to the most important use case of ESXTOP is to run ESXi in batch mode. Batch mode provides us a way to collect esxtop stats from a physical ESXi host and analyze it on a Windows machine using Perfmon. Capture the Data:First thing would be capture only the relevant info and omit all the metrics you don't need.Use ‘f’ to ADD/Remove FieldsUse ‘o’ to change the order of Metrics Use ‘W’ to save the settings that you just edited.Caution: If you don't input a file name, the default settings will be saved as such. We are ready to run the esxtop in batch mode. esxtop -b -d 2 -n 100 > esxtop.csv b=batch moded=delayn=No of Iterationsa=all Metrics Usually capturing esxtop for an extended period of time can result in a large file. In order to avoid this, we can zip

I’d like to rename the host name on a single-node cluster - assuming that I update the name in the /etc/sysconfig/network and /etc/hostname files, I guess I would also need to stop/start the acropolis service. I know this is safe to do on a 3-node cluster but is there are risk/impact with a 1-node cluster?

Hello,I was hoping to get some clarification as to what features are included in AOS Starter.  I usually use the following link as a guide:Nutanix Software Editions & Licensing: Solutions to Run on Our AppliancesThe above link states that “Basic Compression (LZ4) - Inline and post process” are included starter.  However as soon as I enable post compression I get a license violation notice.  In prism element it also shows the available features for starter and post compressions shows as yes:Is post compression available in Starter? Also the link states that lz4hc compression is not available for Starter but running the following command on a starter clusters show it is available and compressing data:curator_cli display_data_reduction_report Has something changed to make lz4hc available to starter? Is there another document or link with a comprehensive list of features available for each edition? Thanks,--Zip

As i know that if drive failure, Nutanix will rebuilt the data immediately. May i know if node failure, how long does the Nutanix will trigger to rebuilt if have sufficient node and capacity in existing cluster? Thanks

There are instances when you have to perform a rolling restart of the CVMs (Controller VMs) or a rolling restart of the hypervisor hosts or a restart of just one of the CVMs. This is a list of health checks to execute prior to the restart to verify cluster health. Verify if any nodes or services are in a 'down' state. Run the following command for smaller sized clusters: nutanix@cvm$ cluster status If the cluster contains multiple nodes, running the following command which excludes services that are UP from the output may be more convenient:nutanix@cvm$ cluster status | grep -v UPNodes or services that are unexpectedly in a 'down' state need to be fixed before proceeding with the restart.  Verify if any nodes are missing or are in a 'down' state in the Cassandra ring. There should be the same number of nodes as the number of IPs in the svmips output (four nodes in the example below). If a node is missing, it means it was removed from the Cassandra ring:nutanix@cvm$ nodetool -h 0 ringAd

LCM 2.4 introduced a new protocol called the Redfish Protocol. It uses a RESTful API interface for server management. While there are many improvements introduced in the backend, there are a couple of improvements done on the frontend as well.The main improvement on the frontend is that LCM now performs the BMC and BIOS updates using Redfish twice as fast as the older method of using a Phoenix ISO. The time gained is due to fewer restarts needed for BMC and BIOS (no restarts needed for BMC updates and one restart for BIOS updates).While there are specific requirements for LCM to utilize the Redfish protocol, the LCM UI in LCM 2.4 displays this information in the Inventory Pane.For more information about the requirements and the LCM UI, take a look at the Redfish Protocol documentation on the Support Portal.

Dear All,May I have a question about the below situation?RF=23 node cluster2 x disks failure in same nodeMay i know whether the cluster will be corrupted or not? From my understanding, it should not be corrupted as 2 x disks failure in same node (NOT different node).

HiI’m using Nutanix Prism Central v3 API and I want to run the API call referenced here:https://www.nutanix.dev/reference/prism_central/v3/api/categories/postcategoryquery/to get the category information.I’m calling this API: https://<prism_ip>:9440/api/nutanix/v3/category/query, using Postman. My problem is filling the request body. The example at the bottom of the page shows this request body:{  "api_version": "3.1.0",  "group_member_count": 123,  "group_member_offset": 123,  "usage_type": "string",  "category_filter": {    "type": "CATEGORIES_MATCH_ANY",    "kind_list": [      "string"    ],    "params": {}  }} But the params property is empty and I can’t figure out how to fill it properly.It says in the description that it’s supposed to have “a list of category key and list of values”, but no matter what I try I either get an error regarding the json structure or this error: For a search specify the correct usage type. Can someone please provide an example of how to use this

HiIs there a way to check the versions of all Nutanix components in one view? “ncli cluster info” displays the AOS and NCC versions, but not those of AHV and PC. The AHV and PC versions may be obtained from the PC UI (in different places though). Further, the Nutanix release timeline shows AOS 5.18 as the latest, but the documentation has tags for 5.19?
