Nutanix Cloud Manager

I am looking to monitor performance of my Volume Groups during third party backups. I am using a 3rd party vendor and when the backup starts, Volume Groups are created for the snapshotted disks. I want to create a metric/entity chart but want to see if there is a way to create one for ALL Volume Groups so when a new one is created, it is included into the chart. Currently I can only see creating it while one exists but I want to monitor it from start to finish periodically.

Every infrastructure admin knows the importance of the correct time zone to be configured in architecture otherwise, administration jobs and log analysis between different components is nothing but a nightmare to go through.So do we have an option to change the time zone of the CVM in a Nutanix cluster?Yes, we do!Give the following KB a read to know the procedure to change the time-zone of the CVMKB-1050Nutanix Cluster Check(NCC) also have a check which confirms whether the CVMs in a Prism Element are in the time-zoneFor more information on the checkKB-2044Confused regarding the procedure or have further queries?Drop a comment and let’s start a

Hello, I've been looking relatively hard for a comprised list of STS and LTS release dates and a indexed link to the readme's for those releases and perhaps the CVE's addressed in those patches. Seems like it would be easy to find but I'm struggling.

LifeCycle Manager (LCM) is the 1-click upgrade process for firmware and software on Nutanix clusters. This feature can be accessed through the Prism UI. LCM Provides Two Operations:     1. Inventory: Detects what can be managed on a cluster.      2. Update: Performs an update to a certain version.So what happens before an update?LCM runs a set of pre-defined checks, pre-checks to confirm and validate your cluster health and sanity. If any checks fail, it shows you as an error and advises you to fix the issue before going ahead with the upgrade.So what are those pre-checks?Do we have a list and recommendation if we encountered a pre-check failure before the upgrade or if we want to the know the list of complete pre-checks to proactively make our cluster ready for an upgrade? Of course, we have a list of pre-checks and the recommended KBs to help

Sometimes it is necessary to delete and re-deploy Prism Central (PC) VM. Instances may include errors that occurred during PC deployment or when PC version deployed is outside of Software Product Interoperability matrix. Starting with version 5.5, Prism Central becomes the primary management plane and houses features like SSP, Calm, RBAC, Microsegmentation, etc. Therefore it is important to follow the recommended process when deleting PC VM: Identify the cluster on which the Prism Central VM that you wish to delete has been deployed. Copy the Prism Central VM name from this cluster. Unregister and clean up all clusters registered to Prism Central. Check if all clusters have been unregistered from Prism Central by executing the following command from any CVM in each cluster. Delete the Prism Central VM. Check if the Prism Central VM has been deleted by logging into the cluster's Prism Element UI and browsing the VM section.

Using less storage for more data is awesome. After all storage does not come cheap. Files Servers often become black holes of storage space in the environment where they consume space rapidly and ever increasingly. While using deduplication on Nutanix Files container might seem like a good idea at first, unfortunately, it is not recommended.Excerpt from Nutanix Files Tech Note:Every file server maps one-to-one to a container. This mapping allows you to manage compression and erasure coding individually for each file server deployed. Inline compression and erasure coding are turned on by default to save capacity. Deduplication is not recommended. [...]From Files 3.6 onward, you can control compression on a share-by-share basis. When you create a share, compression is enabled by default. This is backed up by NCC health check file_server_container_check which fails if deduplication is enabled on a con

In our previous post, we explored “where are vdisks stored for AHV VMs and how to access or download them”. In this post, we will briefly go through the AOS Image service, which contains all ISO images, disk images etc.What is AOS Image Service:The image service feature enables you to import the images (ISOs, disk images, or any images which are supported in ESXi or Hyper-V format) directly into virtualisation management.The raw, vhd, vmdk, vdi, iso, qcow2 disk formats are supported.You can import images from http or NFS source URL. You can use this feature to create disks for a VM from images (images that are stored in the image library or repository) and also an option to clone from an image. You must install virtIO drivers on t

Hi community I am planning an upgrade of our Hypervisor of ESXi from VMware ESXi, 6.5.0, 8294253 to 6.5 U3 Latest build. Just wanted to get some feedback whether the process I have would be the correct one? first time we plan to use the one click upgrade process! We have 2 clusters, a production and DR cluster. We do use Data protection and Async DR and I believe that the target Async environment needs to be updated first which is the preferred option anyway.  This is the approach I was going to take. Any feedback on this would be great. Prism Central SpecificNCC (already upgraded to latest 3.9.2.1 version)Prism Central from 5.10.4 to 5.11.1.1We use vCentre VCSA 6.5, we plan to also upgrade this to later patching level.

Is there a way to unack and unresolve alarms that have been marked wrongly or needs to be passed between shifts and operators?

We all have a safe number in our head when it comes to storage utilization rate. Depending on professional background the answer will vary between 75%-85%. Sure, would that be of total space? Total space per node? Let’s take a look.This example assumes a five-node cluster consisting of the following. One (1) four-node Model NX-3050 The physical storage capacity available is 4.48 TBs per node, or 17.92 TBs total One (1) node of a Model NX-6060 The physical storage capacity is 13.91 TBs per node The total physical storage capacity available to use on this cluster is: (4 x 4.48) + 13.91 = 31.83 TBT = 31.83 N1 = 13.91 N2 = 4.48The recommended maximum utilization of this cluster when using Replication Factor of 2M = 0.9 x (T - N1 ) 0.9 x ( 31.83 - 13.91) = 16.128 TBThe recommended maximu

Hi all, I am working on a DevOps platform for a client and considering recommending Calm to automate the provision of TeamCity builds if the build queue meets a condition (i.e. if 15 builds in queue then spin up 5 build agents and add them to the pool). Has anyone done this with Calm ?

We had an issue last evening where one of our nodes decided to take a dive. (Uncorrectable memory in one of the DIMMs).Anyways, I happened to check my email this morning and was like wonderful. So I hopped on to check things out. Turns out the node is indeed unable to boot. So, opened a case. A speedy response - yay!However, I am wondering what type of alerts that are automatically sent to nos-alerts trigger a support case? One would think that a node down and the cluster in HA state would trigger a support case… so I checked the postfix logs and see that an email was sent when everything occurred last evening… which leads me to ask, “What exactly will trigger an alert on the support end if this particular issue didn’t?”Thanks for any insight. Loving Nutanix so far.

Hi, Does anyone know what cause the "Admin User API Authentication Check" result with "Warning" ? I have not clue, please help. Thank you,

You have multiple storage containers in your AHV Nutanix cluster(Nutanix recommends having a single container to simplify operations) and have a need to move a User VM from one storage container to another but confused regarding the process.Let us guide you by giving a brief summary of the operation you need to perform.If you’re using AOS 5.5.X and 5.6.X and cluster is managed by Prism Central consider upgrading or following the steps mentioned in  KB 3577 to download VM disk file from source container to workstation and then upload to the destination container.For other AOS version, the following steps would help. Find the VM disk files using the following command from any CVMnutanix@cvm:~$ acli vm.get <VM name> include_vmdisk_paths=1 | grep -E 'disk_list|vmdisk_nfs_path|vmdisk_size|vmdisk_uuid' This will give us the

How do clean old Prism Alerts.  Within Webconsole Resolve and Acknowlege doesnt clean old alerts.  Any command would helpful.  Thanks,   

I want to pull alerts from my cluster using ncli. however, the alert message gets truncated. here is an example: code:ncli> alerts ls max-alerts=1 ID : XXXXXXXXXXXXXXXXXXXXXXXXXXXXXX Message : Unable to locate VM(s) VM1, VM2, VM3, VM4, VM5, VM6, VM7, VM8, VM9, VM10, VM11, VM12, VM13, VM15, V... protected by protection domain 'PDgroup2'. Notice the truncated portion with '...'. Is there a switch i can send with ncli to prevent that truncation?

Hello, we have only recently implemented Nutanix in our environment so apologies if this is a noob question. My issue is this: I have a 2012 Server VM that I need to repair using the CMD prompt. I am adding a CDROM with the Server 2012 ISO mounted and set to boot. After Windows setup loads I open CMD prompt but the disk where the OS is installed can't be found. Its as if only the ISO is being seen and no other drives. What am I doing wrong?
