Does anyone have some experience with running SAP on Nutanix, doesn't matter if it runs on HyperV or VMware. Oracle or MS SQL is ok. Just looking for some feedback and best practices. Kind regards Bart

Hi, We have applied license to Nutanix cluster running on vSphere. Then we created cluster with AHV from scratch without reclaiming it from Nutanix portal. How to regenerate license for newly created license? Thanks in advance. Vivek

Hi, We have setup in pri production stage. Cluster is having 2 x 800 GB disk & 2 x 6 TB disk on each node. Cluster is having 3 nodes. We removed single disk from one host & after 10 min. we reinserted disk in same slot. Now cluster is showing 11 disk & not allowing us to format disk which is reinserted. How to add this disk to current cluster? Thanks in advance. Vivek

Hi all, I have a upcoming appliance installation and it might be necessary that we need to downgrade the current NOS version. Is there an out-of-the box approach / method available that could be used to downgrade an existing cluster? Or maybe KB-articles that could help me regarding this issue? Thank you and best regards, Andreas

Hello Folks, I`m busy installing a 6 node cluster, some errors or doubt comes out along. my environment : 3 block, 6 nodes (2 nodes/block) AOS 4.6.2 一. When I create a new container, make the Enable Erasure coding button checked, error pops up"enable EC-X will break the current block awareness !" seems mean ECX will disable block level awareness ? 二. As many of us know, if need locate the physical slot location of a disk, you can simply led on that drive. but there is possibility led on function inaccurate or disabled, in this scenario, you must locate the disk by disk id rule, e.g shelf id.slot/bay ID, but the DISK ID in prism hardware section seems ramdom/ruleless number, I can`t locate physical location for a disk. 三. When I do the test about removing a node from nutanix cluster, A doubt appears: Do I need or is it the best practice to execute storage vmotion(other then only vmotion vm`s ) before removing the node ? I think the diffecrence of two methods is who is the data mov

Good day, Quick question regarding Exchange on Hyper-V, I havn't been able to iron out all the questions regarding the support for Exchange on Hyper-V where the .VHDX files resides on the backed SMB3 part. From a Microsoft stand-point they support .VHDX files on SMB3 as long as it's backed by block storage, but I havn't been able to verify that Nutanix actually goes under the "Block-Storage" part, on my own mind it should. There are a few documents where Exchange on Hyper-V is mentioned, and in those SMB3 and iSCSI are both mentioned but no on what part (SMB3 for OS, iSCSI for Databases or in fact VHDX on SMB3 for databases also). VMWare is rather straight forward, Volume Groups to be fully supported by Microsoft, period. But what is the stand-point regarding Exchange on Hyper-V where databases are .VHDX on SMB3 from a Microsoft and Nutanix perspective? Kind Regards

Hello, I`m not new to nutanix, but have a long time not focusing on nutanix installation step. while I installed nutanix with foundation+Phonex(NOS location selection)+Hypervisor image one year ago, I think Phonix is just exactly NOS at that time. I find it seems to have new method to image node: Foundation+AOS(NOS location selection)+Hypervisor image, or even having an JAVA applete+Foundation+AOS(NOS location selection)+Hypervisor image I`d like to confirm detailed difference between NOS , AOS, and Phoenix. I have asked guys, no one can explain this clearly to me. also what make me confused is there are varous statement about it in different guide(it is self-contradictory) , also Which phonex package should I use ? shows you need manually make/generate phonix ISO with AOS , but sees you shoud use the Phonix ISO downloaded from nutanix portal site ! look at these slices : "Phoenix is a tool used to install the Nutanix Controller VM and provision a hypervisor on a new or rep

Hello everyone, my environment: 6 * 3060-G4 NODE per node : 2*ssd 480G， 4* HDD（how to find out if it`s sas or sata drive ?）1TB RF=2 --------------------------------------------------------------------------------------------------------- how to calculate? I see prism report 22.18TiB MaxCapacity(Physical)。but I think physical should be 1T*4*6+480G*2*6=24T+5760G if RF2 need two complete copy(like RAID1) ?, the usable capacity is just half of 24T+5760G, and if after one node failure, for N+1 , I should also reserve another extra node capacity(4T+480G*2) ? also I have a basic question and guess, if I have three NODE in all(assume not 6 node ), and one node failed, lost data will be replicate to another any node of remaining two, because of RF. so I have two copy again. but if the second node also fails later(now I have only one node), will the cluster be down ? data lost ? I think data shouldn`t be lost because one of the two copy exists(3 node ,2copy-> 2 node 2copy-> 1node 1copy)

Hi, Is there any way that we can monitor a particular VM activity - log file from Nutanix perspective. we keep on getting VM to be rebooted. VM OS: Windows Server 2008 Hypervisor: AHV

Dears, I found I can`t find ESXI 6.0U2 and AOS4.6.1.1 release in Nutanix compatibility online tool. but I can find ESXI6.0U2 in the iso whitelist json. So It make me confused Which release exactly can be supported by nutanix ？ Finally, I install ESXI6.0U2 and AOS4.6.1. I·m not sure if Compatibility tool is just a best practise or not up to date timely. Can I simply always install newest ESXI version and NOS ?

For all My VM's in the tabular view the used space doesn't show up. What should I do to successfully display it? Attached screenshot [img]https://d1qy7qyune0vt1.cloudfront.net/nutanix-us/attachment/1306i98B04ED153640269.png[/img]

We're in the process of deploying our new VDI environment, using View 6 & UniDesk ontop of our Nutanix MetroAvailability Clusters. We will be balancing the number of production desktops running at both sites to spread the load around (we'll have some containers active in site A, some active in Site B), and want to ensure VM's do not get vmotioned to the 'standby' site. Although we do have significant bandwidth (10Gbe via dark fibre) & low latency (~1-2ms) between sites, we'd like to avoid the additional overheads where possible. Is there a way for us to easily create DRS rules within vSphere to ensure VM's on Active Containers at Site A should always run on those hosts & vice-versa for Site B? I vaguely remember coming across a PowerCLI script somewhere that did this (or something similar), but have been unable to find it again. Ofcourse it would be amazing if this could be natively handled by Nutanix, but for now i'd be happy with a script we can run on a schedule to update the DR

Hello we have a brand new cluster (4 nodes) and did some failover testing over the weekend prior to placing the new gear into production. We have 2 cisco 4500x 10GB switches and have the nodes split between the two switches for redundancy. We simulated a switch failover by pulling the plug on one of them and experiened some very bad results. Some CVMs became unresponsive and we lost connectivity to most of our VMs. Has anyone else experienced a similar issue? Or can anyone point me in the right direction for configurations to double check? Would appreciate any insight!

Hi Team , may i know can i install use hyper-v with GUI as hypervisor on Nutanix? Is there any technical limitation? Will it still under support with Nutanix if i install GUI on my hyper-v hypervisor? Kindly advice

Using AOS 4.6 on Hyper-V. I will setup Hyper-V host to join Domain. When read manual, I think setup_hyperv.py change Hyper-V hostname. Is it correct? I already name Hyper-V host. How to run setup_hyperv.py? Thanks

Good morning... evening... night all over the world ^^ I'm wondering what are the technical differences between Async DR and Backup. What I've red in documentation is that Backup does not allow running the virtual machines on the remote site. This comes with many questions as I couldn't find any detailed description of the backup mechanism. As far as I understand, both works exactly the same. Only difference is that on the remote site, the backup target PD cannot be promoted to allow running of the VMs. Is this correct ? is this the only difference ? Otherwise, what are all the differences between both modes ? Any impact on the size of used on the target space ? ...

Hi All , How can I verify the total RAM use on specific VM using Nutanix AHV?

Thoughts I'd post this rather than bugging our SE over and over ;) Trying to get a disaster recovery plan in place to protect against a major disaster such as server room fire... We have a couple of clusters geographically separated which I have set up as remote-sites. Site A and B lets call them. I've set up a PD w/ consistency group with the VMs to protect and periodically snapshot from site A to B. Now in the case of a fire/destroyed cluster at site A... obviously step one is rebuilding a cluster at that site with the appropriate configs, but then... With a brand new cluster in place, what is the standard process to retreive the snapshots from site B back to the new site A ? So far, I've activated the backup on site B (as if it was an unplanned outage and left it off). and recreated the remote-site link on the newly built out site A. I am thinking I now create a new PD to shuffle the VMs/consistency group back to Site A and then activate there and I am done ? I know this

Hi there, we just upgraded to Prism Central using the ESXi OVA, and during creation noticed that there is a 500GB 3rd disk set to thick provisioning. This caused some space concerns on an already tight container, so I flipped it over to thin provisioned although I didnt really want to :) A couple questions.... is this 500GB drive 3 normal? I dont remember having these space concerns with the prior PC install. Any forseen issues with the thin provisioning? other than possible space not available as the disk expands. Appreciate the comments/thoughts.. ..BRent
