Dealing with disaster…how does Nutanix respond?

Things won’t always go to plan and the worst will happen. In this case, we lose 2 nodes from our 9 node rf2 cluster (e.g. one’s down for maintenance, someone forgets and reboots another node at the same time).  Can someone point me at some documentation that outlines how we can recover from this and get the cluster back up and running. Is there any permanent fallout?Thanks.

Basics of MOVE

Nutanix Move is a cross-hypervisor mobility solution to move VMs with minimal downtime. Move supports migration from the following sources to targets, where first platform being the source and second platform being the target. MOVE-where to where?From ESXi to AHV, Legacy ESXi to Nutanix ESXi,AHV to EC2, Azure to AHV, Azure to ESXi on Nutanix,Hyper V to ESXi on Nutanix,HyperV to AHV, HyperV to Nutanix on AWS. What can MOVE do for you?Migration of power on/off VMs,pause and resume migration,schedule the migration activity,centralized platform for migration between several clusters,schedule data-seeding for the virtual machines in advance and cut over to a new AHV cluster, cancel migrations, monitor the migration activity at granular level. Deployment of MOVEThe MOVE package is available in the downloads section of the portal and can be installed on AHV or ESXi. Move must be able to communicate with vCenter Server on port 443, ESXi hosts on 902 and 443, and AHV on 9440. The move package m

Availability of VM

we are using a two node cluster connected with a witness VM, issue is we are facing a downtime of 5 minutes because of transfer of windows vm from failure node to healthy node. we don't want any downtime because we are running Product Of Sell (POS) services in windows. we need seamless solution (e.g without breaking continuous ping).we don't want migration the issue is when the Vm is running on node A and node A fails, it took 5 minutes to start Vm on node B in failover condition ,so it create downtime we don't want this downtime.

Getting stats for a VM seems to be different depending on the stat

While getting some stats for a vm the behavior seems to be different depending on the stat.Is there any documentation for specific stats? Sample Call:metrics: controller_avg_read_io_size_kbytes,controller_avg_io_latency_usecsstartTimeInUsecs: 1631290740000000intervalInSecs: 3600Output (see below):stat controller_avg_io_latency_usecs - give the expected output of a value for each interval since the input start timebut for stat controller_avg_read_io_size_kbytes - A single value is returned. What is the meaning of single value? Is it just the read at that point in time?

Need to understand the available Storage when one node fails when a cluster is RF2

Hello, I have a 3 node cluster with RF 2 configured. When All the nodes are up and running I can see Total Cluster resources as below on the Prism Element.CPU - 388 Ghz RAM - 4.5 TB ( 1.5 TB Per Node) Storage - 32.9 TB  Let’s say If 1 node fails, Will my Available Storage size reduce? Please Help me. Also, I don’t understand one thing, I have Total 42 SSD of 1.92 TB = 80.64 TB, But in reality with RF2 why am I getting only 32.9 TB (without any data efficiency options enabled). I should Ideally get 40 TB of usable space. I checked on the storage sizer portal and it said I should get 63 TB. Please guide guys, what am I missing.

REST API v2 - /vms for Hyper-V not supported

While trying to get the list of vms using the rest api v2 against a Hyper-V configurationThe api return the following error message  "Exception while retrieving entities : Hypervisor hyperv not supported" https://www.nutanix.dev/reference/prism_element/v2/api/vms/get-vms-getvmsThere is no mention of api v2 not supporting this, is it meant to be supported? If not how can we get the list of vms from it? Do we need to revert back to V1 api? This one returns the vm list but looking at the v1 v2 documentation the recommendation is to migrate to v2, so would just like some clarification.Also if we need to go back to V1 for hyper-v will any of the endpoints for in api V2 that require a VM_uuid work for a vm hyper-v or not? Since those uuid were returned by the V1 apiFor example:https://www.nutanix.dev/reference/prism_element/v2/api/flr/get-flr-vm-uuid-attached-disks-getattachedflrsnapshotofvmhttps://www.nutanix.dev/reference/prism_element/v2/api/flr/get-flr-vm-uuid-snapshots-getflrsnapshotsof

Let me know if I can achieve same with Nutanix and direct me towards hardware (Fiber Channel or 10GB ISCSI) whatever is easier and works well.

Networking - br0 - vlan tagging

Hello,I am new to ovs and AHV configurations in general and have a networking question. I have been reading through the documentation on networking and still am not clear on a question or two.Situation: I am mapping out steps to create a DMZ zone for my server environment. My firewall will be configured with a DMZ port and vlan tagged, public IP will NAT to server in DMZ zone, and ACLs will control what traffic can get threw. This will be routed through vlan tagged ports via lay 3 switch to my Nutanix cluster. The server mentioned above will be on my Nutanix cluster and will need to communicate with with 1-4 other Nutanix VMs in the same DMZ/vlan.Questions: If I create a "network" in Prism with vlan tagging and apply it to all  DMZ servers in question, will this keep my DMZ traffic separated from all trusted traffic?If not, do I need to configure a new bridge to keep this network traffic separate from my other networks? My concern is because all traffic is being routed to the same trun

Cluster management-useful commands

Although Prism is user friendly, it will be nice to know some commands that are useful for cluster management.   Cluster status The cluster status or “cs | grep -v UP” command gives the status(up or down ) of all the CVMs and their services. Running this command is helpful when there are alerts in the prism about services being down on certain CVMs.   Metadata ring The command “nodetool -h0 ring” shows if all the CVMs are a part of the metadata ring. Being in a metadata ring is essential for the CVM to be an active part of the cluster and handle its designated responsibilities. It is essential to run this command after every hardware replacement to make sure the node is back sharing responsibilities of the cluster.  Health check Most of the problems in the cluster are easily diagnosed by the health check command “ncc health_checks run_all” At the end of every WARN/INFO/ERR/FAIL plug in we see a KB to further troubleshoot the issue. This check is essential to make sure if the cluster he

Live vDisk Migration across storage containers

vDisk migration allows you to change the container of a vDisk. You can migrate vDisks across storage containers while they are attached to the guest VMs without the need to shutdown or delete VMs (live migration). You can either migrate all vDisks attached to a VM or migrate specific vdisks to another container. In a Nutanix solution, you group vDisks into storage containers and attach vDisks to guest VMs. AOS applies storage policies such as replication factor, encryption, compression, deduplication and erasure coding at the storage container level. If you apply a storage policy to a storage container. AOS enables that policy on all the vdisks of the container. If you want to change the policies of the vDisks, create another container with a different policy and move the vDisk to that container. With live migration of vDisks across containers, you can migrate vdisk across containers even if those vdisks are attached to a live VM. Thus, live migration of vDisks across storage container

PXE Configuration for AHV VMs

You can configure a VM to boot over the network in a Preboot Execution Environment (PXE). booting over the network is called PXE booting and does not require the use of installation media. When starting up, a PXE-enabled VM communicates with a DHCP server to obtain information about the boot file it requires. Configuring PXE boot for an AHV VM involves performing the following steps: Configuring the VM to boot over the network. Configuring the PXE environment.  The procedure for configuring a VM to boot over the network is the same for managed and unmanaged networks. A VM that is configured to use PXE boots over the network on subsequent restarts until the boot order of the VM is changed. To configure a PXE environment for a VM on a managed network on an AHV host, do the following:  Log on to the Prism web console, click the gear icon, and then click Network configuration in the menu. The Network dialog box is displayed. On the Virtual Networks tab, click the pencil icon shown for
