How to delete VMDK from Container?

I have a server that no longer needs one of its 2TB disk. I know how to remove the disk from the VM but, how do I remove that VMDK from the Nutanix Storage container? Is there a way to browse it and then delete it?  2TB is a lot of space that I would like to reclaim.

Nutanix CE - Cannot get to Prism Page

I have setup Nutanix CE in a lab environment but I cannot get to the Prism page when browsing to the CVM IP address. I'm getting the message: [b]Prism services have not started yet. Please try again later.[/b] Although I have run [b]cluster status[/b] and the Prism service is up and running: [img]https://d1qy7qyune0vt1.cloudfront.net/nutanix-us/attachment/ccea7730-811f-4020-ace9-ce68004a0597.png[/img] It is a single node setup on VMWare. I can ping the CVM IP and SSH onto the CVM. Any assistance would be gratefully received! Thanks.

VMFS Version for ESXi Datastore

I’m asking about the version of VMFS datastore for ESXi hypervisor on Nutanix cluster. I’m trying to create new VM with a disk larger than 2 TB with no luck of success, after some google searches seems this issue could be due to VMFS3.

Cluster RBAC

The Cluster role based access Control (RBAC) or Enhanced Prism Central RBAC feature provides “Prism Admin” and “Prism Viewer” role based access to Prism Central with access restricted to one or more AOS clusters registered to Prism Central. With Cluster RBAC, the Prism Central admin or viewer user is able to access Prism Central and view and act on the entities like VM, host and container from the allowed AOS clusters. The users will also be able to perform the “Launch Prism Element” action on the allowed AOS clusters and manage the cluster with respective Prism Admin or viewer access. Enabling cluster RBAC Pre-checks Verify supported the Prism Center version and the AHV cluster version. The AOS cluster where Prism Central is deployed must be registered to the Prism Central. CMSP must be enabled. Identity and Access Management (IAM) is automatically enabled as part of CMSP enablement. The prerequisites for CMSP and IAM also apply to cluster RBAC  Procedure  Connect to the Prism

How do I assign the Super Admin role to users?

Hi.I’m trying to assign users to the built-in roles in Prism Central, for example Super Admin, but I’m not allowed to.This is the exact same issue as @skeeter reported on 5 months ago in this thread.Is this still considered a bug that requires me to open a support case?

Configuring and Troubleshooting SNMP monitoring

We have already mentioned some helpful resources relevant to SNMP configuration. This time we will take a look at examples, logs location and connectivity testing. Important:Nutanix appliances support only SNMP v2c and v3 (support for v2c in AOS 5.5 and higher). Starting from AOS version 4.1, auth-type MD5 is no longer supported. With SNMP v2c Nutanix support SNMP TRAP instead of SNMP GETFollow trough to KB-1333 Configuring and Troubleshooting SNMP monitoring for commands and examples.The article also reference two more KB articles as well as SNMP related PowerShell commands:KB-2448 How to import MIB in zenossKB-2028 Integrating Nutanix with Solarwinds

10 Key with Nutanix Frame

Hi! I’ve been getting some reports of users unable to use the numpad part of their 10-key keyboard in Frame… seems to work outside of Frame just fine, and no, numlock isn’t on :)  I’ve seen it, though I haven’t been able to reproduce it myself, or isolate a trigger for when it happens to people. Just curious if anyone else has come across something like this?

AOS upgrade path 5.1.1.3 to 5.9.2/Latest ( 5.10.0.1)

WE are running on AOS version 5.1.1.3 and planning to upgrade it. When I checked in Upgrade path, the maximum version I can upgrade to is 5.6.2 I need to know, if I want to upgrade to the latest version which is 5.10.0.1, do I have to follow the path like [b]5.1.1.3 >> 5.6.2 >> 5.9.2 >> 5.10.0.1[/b] , basically a 3 step procedure OR is it that I can upgrade to 5.6.2 only. Please share your views.

LCM failed to find node

I had a LCM failure while upgrading firmware on a node. The node entered maintenance mode and I was never able to get it out. I have subsequently removed the node from the cluster so that I can finish the upgrade process. I have successfully completed the firmware upgrade on the other nodes.Now I am trying to upgrade AHV. LCM is failing prechecks with the message Operation failed: Failed to find node <uuid>The <uuid> is the one of the node that is no longer in the cluster. Some how I need to get past this so I can complete the AHV upgrade. I currently have two nodes at the most recent version and one at an old version. Is there someway to bypass the precheck or to modify the LCM data about the removed node so I can press on?

What is Nutanix Volumes?

Volumes acts as one or more targets for client Windows or Linux operating systems running on a bare metal server or as guest VMs using iSCSI initiators. Do not use Volumes to create an iSCSI datastore to Hyper-V or ESXi hosts. This configuration is not supported.The iSCSI data services IP acts as an iSCSI target discovery portal and initial connection point. The client only needs this single IP address to help load balance storage requests and provide path optimization in the cluster, preventing bottlenecks.Enable Nutanix Volume Get the client IP address that you will add to a volume group client whitelist. Create an iSCSI data services IP address for the Nutanix cluster. This address cannot be the same as the cluster virtual IP address. Provision storage on the Nutanix cluster by creating a volume group consisting of one or more vDisks. Perform an iSCSI target discovery of the Nutanix cluster from the clients. [Optional] Configure CHAP or Mutual CHAP authentication on the init

Enabling Load balancing of vdisks in a volume Group

AHV host supports load balancing of vDisks in a volume group for Guest VMs. Load Balancing of vDisks in a volume group enables IO-intensive VMs to use the storage capabilities of multiple CVMs If you enable load balancing on a volume group, the guest VM communicates directly with each CVM hosting a vDisk. Each vDisk is served by a single CVM. Therefore, to use the storage capabilities of multiple CVMs, create more than one vDisk for a file System and use the OS-level striped volumes to spread the workload. This configuration improves and prevents storage bottlenecks. vDisk load balancing is disabled by default for volume groups that are directly attached to the VMs. You can attach a maximum of 10 load balanced volume groups per guest VM. For Linux VMs, ensure that the SCSI device timeout is 60 seconds.  Procedure: SSH into the CVM as a nutanix user Do one of the following Enable vDisk load balancing if you are creating a volume group acli vg.create vg_name load_balance_vm_attachm

how to change the ssh control for CVM

Hi I have a question in the Nutanix enviroment.I need to change control for the ssh to CVM so that just some IPs can access to avoid some intrusion access.I checked the <Nutanix security Guide> and there are some descriptopm in TCP Wrapper Integration, But after I changed the file of /etc/hosts.allow to include just the allowed IPs and CVM management subnet. But It will be changed to default after the cluster security config schedule(by default daily.) Is it possible to change the sshd allow list to achieved this goal? there are security requreiments for the enviroment. thanks.

Changing default gateway for CVM/AHV

Hi everybody,We’re doing a slight restructure in our DC and in thus need to change the default gateway used by a Nutanix cluster (3-node cluster).I’m aware of the following guide:https://portal.nutanix.com/page/documents/details?targetId=Advanced_Admin-Acr_v4_6:ip__ip_reconfig_web_c.htmlBut isn’t it at all possible to change something as simple as just the Default Gateway without such an invasive procedure requiring downtime?The part of the article on how to do it manually is...Non-existent:https://portal.nutanix.com/page/documents/details?targetId=Advanced_Admin-Acr_v4_6:ip__cvm_ip_address_reconfigure_t.html

Setting NIC speed

Hi community, I have some Qlogic 10G/25G NIC cards in my cluster which as I understand are not “supported” however seem to be detected correctly to some extent. Manage_ovs show-interfaces displays the output below which leads me to belive that the driver is loaded. However, currently those ports are connected to a 10G switch and so the speed and the operational status are not correctly working. Is there a way to set these by hand?  manage_ovs show_interfaces    name  mode  link speedenp5s0f0 25000 False  Noneenp5s0f1 25000 False  None    eth0  1000 False  None    eth1  1000 False  None    eth2  1000 False  None    eth3  1000 False  None    eth4  1000 False  None    eth5  1000 False  None    eth6  1000 False  None    eth7  1000  True  1000 When I add those cards to a vritual bridge I get the error message below. manage_ovs --bridge_name br1 --bond_name bond1 --interfaces 25g update_uplinks2021-03-31 18:05:50,402Z WARNING manage_ovs:437 Interface enp5s0f1 does not have link state2021-03-

NGT Upgrade messages - what do they mean

Good morning All   I have a bit of an NGT issue, the Prism Central alerts me to say some VMs need a NGT upgrade, when I go to upgrade them I see the message “NGT can only be upgraded on 0/1 VMs which have the available upgrade of NGT”   Review and confirm buttons are greyed out so I cannot continue - what does the message mean and what do I do to get it to work?   Many thanks   Eric
