Nutanix licensing for DR

Is nutanix licensing tied to hardware?   use case for the question is a cold DR site.Scenario - VMs are backed up w 3rd party product and replicated to a DR site, e.g. SunGard,  and now its time to restore them for the DR test.If using Nutanix at this cold DR site, you have to build it from scratch before you can being restoring VMs to it, can the licensing used at the primary site be used for this?  or is the licensing restricted to the hardware it was installed on at the primary site?

Private networks

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?

oplog_episode_count_check for a disk not connected to a vm

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 (... :    Fingerprint On Write      : none    On-Disk Dedup             : none Which doesn’t match any of the disks for my VMs.  The NFS File Name makes me think this is some kind of system disk or something.  Ca

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. Turn on the server to the SPP ISO. Connect to the iLO by using the iLO IP address. Log on to the iLO user interface by using the administrator credentials.The default administrator user name is Administrator on all HPE® ProLiant® servers. Passwords for the iLO administrator differ from one server to another, and are available on the service tag on the server. Attach the SPP ISO to the server by usi

Cannot add target cluster to X-ray

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.

Nutanix Move and AWS Permissions

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 according to the User Guide values. Also, it should be verified that the Windows VM instance is properly managed by the AWS SSM Manager prior to a migration attempt. Further information regarding this can be found within the AWS to Nutanix Clusters on AWS and AHV VM Migration section

Migrating VM Disk to a Different Container on AHV

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

Direct log collection for Nutanix case via Support Portal

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.

Graceful Shutdown of Nutanix Cluster using Vertiv Liebert UPS

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?
