Volume group with multiple Disk for Windows failover Cluster

Hi all,Today we have Set up a Windows file failover cluster.WE have configured a volume group with one vdisk for quorum and one volume group with two vdisks for data.Windows see the two disks in the second volume group seperately. WE have attached the volume groups directly to the Windows VM.Why is the volume group seen as seperate disks?Should it not be only one? Regards,Thomas

Initial Configuration: AHV passwords (root, admin, nutanix)

Hi all,I just setup a new AHV environment and was wondering if it still needed to change the passwords for the users:adminnutanix...on AHV!https://portal.nutanix.com/page/documents/details?targetId=AHV-Admin-Guide-v6_8:app-ahv-access-initial-config-t.htmlThe reason for asking is, that they do not seems to be the default passwords (tried to login with them  - did not work: nutanix/4u) - and also the standard alarm that informs that you need to change these disappeared just after I changed the root password!Has something changed in ver. 6.7 / 6.8 ?

Replication

Hello, I am seeking your assistance with enabling replication on my cluster, which consists of 5 servers and 60 VMs. I am undecided between Metro mode and Asynchronous mode on Prism Central. Given that I have two clusters using Metro-type replication, we encounter difficulties when Metro mode is activated, as clients experience significant slowdowns on their VMs. This is why I am considering enabling Asynchronous replication on Prism Central. My question is: if I activate Asynchronous replication on Prism Central while other clusters are using Metro mode, will this have any impact? Thank you for your help.

Migrating Data from Old VM to USB Drive

Hello,We have an old VM that is in our Nutanix cluster. It is running an old version of Windows server, and our Cyber department does not want it connected to the network. There has been a request to retrieve historic data from the server.  Is there a way to boot the server with the network disconnected and use a USB drive connected to the Nutanix host to export the data? If there is no way to do that what other possibilities will work? Can the virtual disk from the old server be mounted on a new network connected VM? Thanks

Eve-NG: Build Virtual Labs on Nutanix

Create your own virtual networking / security lab without having to purchase hardware.Eve-Ng is similar to another popular networking/security tool called GNS3.  I’ve run (GNS3 successfully on HyperV.)Both products are network emulation hypervisors that allow you to, say, load real IOS images from your environment to run them as virtual appliances.  You can emulate routers, switches, firewalls, WAPs, clients, web servers, etc.Then you can test IOS upgrades, routing changes, or whatever you want without having to risk messing with your live environment.  It’s also a great tool for education.The environment has a visual dashboard that allows you to see your network in a GUI, similar to Cisco Packet Tracer, GNS3, or MS Visio.Eve-ng is based on KVM and appears to be running very well nested inside AHV.https://www.eve-ng.net/You will need to prepare AHV to allow the VM to run as a nested hypervisor.The following commands will allow you to do that and so far that is all that was needed to ge

Windows VM does not detect local vdisk

Hello Team. <issue summary>Windows server 2016 VM was restored after async DR to another cluster. If I check through Prism or CVM acli, the local vdisk looks normal in the list.However, some local vDisks are not recognized inside Windows OS.The disks are not identified in "Create and Format Hard Disk Partitions" at all.The weird thing is that other local vdisk looks normal.VG attached in DAS way looks normal vdisk.async DR was performed from AOS 5.20.5 to AOS 6.5.5.5. <Current Environment>- AOS 6.5.5.5- OS : Windows Server 2016 Standard- VirtIO : 1.2.3- vdisk bus : scsi If you restore it from the AS-IS cluster and check it, the local vdisk looks normal on the OS.In a TO-BE cluster, some local v disks are not recognized by the OS.Has anyone had a similar experience?If you have any, please tell me about the solution or cause. Thank you.
