Aged third-party backup snapshots present

What are the 3rd party snapshots? Third-Party snapshots are generated by a third-party backup tool over API calls to our storage. The Nutanix system does not manage this type of snapshots and will keep the snapshots until it receives a deletion instruction from the third-party tool.   The NCC health check aged_third_party_backup_snapshot_check checks the cluster for dangling third-party backup snapshots that may be present for a protection domain. If a third-party backup snapshot has existed in the system for longer than the specified period, this check will raise an alert. These backup snapshots are snapshots that are generated from 3rd party backups (Veeam, Commvault, Rubrik, HYCU, etc.).    The check passes if third-party backup snapshots are not present in the cluster longer than the configured threshold. The default threshold is 7 days, but this threshold value can be modified. The threshold can range from 1 day to 365 days. For more information, examples and solution check out K

REST API to Convert IDE Disks to SCSI

Hi Folks,   I have a few machines I would like to convert from IDE to SCSI.   I understand this can be done with acli. The procedure is to clone the ide disk and replace it for the VM.   nutanix@cvm$ acli vm.disk_create <vm_name> clone_from_vmdisk=<vmdisk_UUID> bus=scsi   However, I’d like to do this in PowerShell given I’ve already started developing down that track. I have PowerShell cmdlets to snapshot and shutdown the VM which are recommended steps before performing this task.   I didn’t see a cmdlet to perform the clone and replacement, so I turned to the REST API. I am fairly new to Nutanix to I wanted to get some feedback on whether this is the right approach or at least that its not going to break anything other than my test VM. $uri = "https://$ntxCluster/api/nutanix/v2.0/vms/$($vm.vmid)/disks/attach"$body = '{"uuid":"abcdefg-08h3-4i44-95j0-kl44m82no758","vm_disks":[{"vm_disk_clone":{"disk_address":{"device_bus":"SCSI","device_index":123}}}]}'$headers=@{}$headers.A

Cluster can not tolerate 1 node failure(s) and guarantee available rebuild capacity

Hi all I have a 3 nodes cluster with RF2.

Not able to Delete Snapshot of a Deleted VM(AHV)

I have exported list of all snapshots running on AHV in our environment. On a few snapshots, VM name is empty. I suspect, this is because VM has been deleted without deleting snapshot. Now how to delete such snapshots? Below is example: Snapshot name is “removing ngt” VM-Name Snapshot-Name Creation-Time   servername Test Snapshot 3/19/2019 11:00     removing ngt 2/6/2020 1:00

Nutanix with Cisco Catalyst 9300

We are planning to connect 2 stacked Catalyst 9300 to a Nutanix Cluster. While doing research I found a document recommending the Nexus 9300 and specifying that the Catalyst 9300 wouldn't meet requirements for the Data Center. There was no reasoning for this and I would like to know why the Catalyst 9300 switches are not recommended. Thanks in advance, Ingrid

How to modify the hostname of the Controller VM?

This article describes how to rename the CVM entity in Prism within the AHV environment. This does not change the hostname of the CVM displayed in a console/SSH session as the hostname is a value configured within the CMV OS and is independent of the Controller VM name entity recorded in the Prism entity DB (Insights Data Fabric). It is the same name as in CVM’s XML definition on the AHV host. It can be checked by listing VMs on the host. The name displayed is the name that is shown in the Prism Wen console. Starting from AOS 5.10.10, 5.15 and 5.16, change_cvm_display_name script is available on CVM that can be used to change the display name.   Following is the overview of the rename procedure: Complete the pre-checks:  Name must start with NTNX- and end with -CVM. Only letters, numbers and "-" are supported in the name. CVM should be able to receive a shutdown token. Once CVM has shutdown token it will be turned off.  The script does not put the CVM or the host into mainten

Understanding alert node "marked to be detached" state

There may be instances where you'll receive the following alert in your environment      "Cassandra on CVM x.x.x.31 is now detached from the ring due to Node was down for a long time. Node detach procedure done by x.x.x.41."   Before understanding the alert, let's first understand what is Cassandra and the ring-structure?    Cassandra stores and manages all of the cluster metadata in a distributed ring-like manner based upon a heavily modified Apache Cassandra. The Paxos algorithm is utilized to enforce strict consistency. This service runs on every node in the cluster. The Cassandra is accessed via an interface called Medusa   To know more about Cassandra and the ring-structure, try going through Nutanix Bible which explains the architecture. .      Cassandra has a feature called auto-ring repair which helps to prevent taking the cluster down due to multiple node failures at different intervals.   The following article lists more information about the alert, auto-repair feature and ho
