We are facing performance issues with Nutanix volumes configured with Oracle RAC physical nodes. The latency is very high (25-30 ms).  Anyone has any suggestions on this.

I’m trying to move a VM (Ubuntu 18.04), when the cutover is done and i make a console connection the VM, at first the screen is blank, but after a few enters, i start getting the following signs on the console:Anyone has any ideas how to avoid this? I’ve tried installing NGT prior to moving the VM - no luck. On the initial GNU GRUB screen where I choose which OS to boot, everything is fine.

Hi all expert,I have question on vdisk and volume group on VMpros and cons using vdisk? pros and cons using volume group?Let have a discuss on which is better for daily operation and maintenance. 

I have a question regarding private networks.  I have an NFS share that resides in the 192.168.20.x network, however my Nutanix public (Internet access) network is in the 10.10.2.x.  I need to create a network where my VM can talk to the NFS server.  I’ve reviewed some YouTube videos but they’re not very helpful.  Any better documentation out there?

Been having oplog errors for nearly 5 months now. I have read through the article: NCC Health Check: oplog_episode_count_check and I have been able to get the vdisk_id. The problem is that it not connected to any VM.  I have looked through all the disks connected to all my VMs and none of them are this disk. Running vdisk ls does give me this information though:     Name                      : 00054ce8-d482-d9dc-135d-1866da8ea766::NFS:2:0:457    Container ID              : 00054ce8-d482-d9dc-135d-1866da8ea766::1062    Container Uuid            : 75138a04-e025-4510-a9d1-05e319573732    Max Capacity              : 4 TiB (4,398,046,511,104 bytes)    Reserved Capacity         : -    Read-only                 : false    NFS File Name             : counters-4    NFS Parent File Name (... :

UPGRADING SERVER FIRMWARENutanix recommends that you use the Service Pack for ProLiant® (SPP) ISO file for applying firmware updates. Perform this procedure on every host in the cluster, one host at a time. About this taskTo upgrade the firmware on a server, do the following:Procedure If the server is part of a Nutanix cluster, place the server in maintenance mode.Information about placing a server in maintenance mode is available in the host management section of the Acropolis Command-Line Interface (aCLI) documentation. See the Command Reference for the supported AOS version.

Can a Nutanix Storage node contain more secondary VM copies than what would fit into the existing capacity on the cluster nodes disk? and if yes, how does one bring the storage node down for maintenance?  

The network panel in ESXTOP has a few metrics that will enable you to determine issues such as loss of network on a VM or high dropped packet on specific nics. Below is simple overview on how to use esxtop for networking: How to access:Log into your ESXi host and type esxtopPress ‘n’ to show only the networking view 

I am using the newest version of X-ray (3.10.0) to connect to a vCenter (6.5U1d) to have some performance tests for my cluster. At the step 4 (Validation) of creating the target cluster, it failed to validate the cluster.Error: Target cannot be verified.After looking into the log, in the HTTP Response body, it contains the 500 Internal Server Error. Still cannot get what it means as everything seems fine and the connection from X-ray VM to cluster still has no problem at all.

Is there support for Cloudstack and Nutanix or drives for it to run.

I’m relatively new to Powershell and have been looking for the cmdlet get the Role Mapping information from a cluster. I’ve no issues connecting using Powershell I just cant find the correct cmdlet which will allow me to get the Role Mappings. My apologies if I haven’t placed this is the correct group.

As part of the Nutanix Smart Support, information about dispatches can now be viewed directly from Portal.

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.

When migrating Windows VMs from AWS into a Nutanix cluster and while using automatic Windows VM preparation, it is important to verify permissions configurations in two places within AWS. Specifically, the permissions for the AWS account that is provided when adding an AWS source into Move and the permissions of the IAM profile associated with the VM instance to be migrated. AWS allows permissions configurations to be viewed/updated in a JSON format. Further, the Move User Guide also lists the necessary permissions for these entities in a JSON format. These JSON values can then be reviewed/compared and, if any of the permissions are missing or configured incorrectly from AWS, simply update the permissions accordi

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 contain

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 Porta

I have read the documents and manuals of APC PowerChute Network but it is a scenario that doesn’t apply to mean. Apparently, someone sold to the customer a Vertiv Liebert GXT4 UPS. Liebert’s engineers concluded that the product couldn’t provide a graceful shutdown of the Nutanix cluster, while it could shutdown the ESXi on top.Is there anyone out there who had succeeded in performing a graceful shutdown without APC?

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 

We are planning to add new nodes to existing clusters.Before the extension, proceed with the new Node AOS install (Bare metal image) and then add.At this time, I want to know if there is no problem if the existing cluster AOS and the new AOS are different versions.ex) Existing Cluster AOS 5.10.9 / New Extension Node AOS 5.15.xPlease give me some advice.Thank you.

vCenter 7.0U1c and vSphere Clustering Service VMs on local or shared storage.After test upgrading vCenter from 6.5U3 to 7.0U1c (which worked just fine w 0 issues), every vmware cluster with DRS and/or HA enabled gets 3 new vCLS (very tiny VMs w 2GB storage/.13GB RAM).When NCC is ran it registers 3 WARNs that there are VMs running on the SATADOM’s. I would assume that, even what (little) they do (today), would this wear out Satadom’s or M.2’s?Would this be a concern for G4/G5’s (w Satadoms) and not G6/G7’s (M.2’s)?”While vCLS can be moved to shared storage, wouldn’t they be moved back to local storage during an NX cluster stop?(Like to point out this was done in a LAB environment, not in Production… no bits nor bytes were harmed during the upgrade progress.)
