Occasional "Address Unreachable" errors with offline Foundation

I occasionally get errors on network validation when using the offline Foundation installer. Usually this is resolved by trying another range- occasinally not. I never have this issue when using the standalone version of Foundation. I am using a completely flat switch (which has had many successful installs), additionally this is with Foundation 3.2.2 and Java 7.45. I can log into the hosts/cvms and get successful pings from all of the IP's I'm intending on using but offline Foundation is adamant that some are unreachable. I solve this by using standalone (which can be a little cumbersome on the road). Just wondering if anyone else is experiencing this as well.

Strange Foundation process

Hi everyone, I imaged a nutanix cluster these days, and found strange phenomena. I found many error key words in foundation node log, but imaging showed successful finally. I clicked "retry imaging failed nodes with last config" many times, after some node failed, and it succeed. I`d like to know why it failed and succeed after just retry. also the foundation process tab showed 3 node failed at 78%, and the node log showed it`s finished ! and after retry, it`s 100%. I`m very worried about if it`s truly successful and there`s potential risks. p.s my environment: Foundation 3.1.1, AOS 4.6.1, ESXI5.5U3D，NX-1065-G4 [img]https://d1qy7qyune0vt1.cloudfront.net/nutanix-us/attachment/1437iFB4C37F4160B7ACC.png[/img] [img]https://d1qy7qyune0vt1.cloudfront.net/nutanix-us/attachment/1439iD2B0077C9E4C1B09.png[/img] [img]https://d1qy7qyune0vt1.cloudfront.net/nutanix-us/attachment/1441i15C9718ECFC6FC6C.png[/img][img]https://d1qy7qyune0vt1.cloudfront.net/nutanix-us/attachment/1443i821C11FF15

can I Separate cvm mgmt and esxi mgmt

Hello Folks, NX-1065 has only two 10G port, and two 1G port. and I have only one pair of 10G switch, and one pair of 1G switch. In my opinion, I`d like to make ESXI port(mgmt, vmotion,nfs vmkernel), and CVM port(prism mgmt, cluster mirror ) run on 10G switch, and configure 10g switch uplink to other network which I can connect to ESXI MGMT and prism. make vm data port connect to separate 1g vswitch. but network guy told me the 10g switch can`t uplink to externel network, so I`d like to know Can I move the ESXI port (mgmt) and CVM mgmt(VIP) to 1G vswtich， and create addtional vmotion,nfs kernel port connected to 10G vswtich, also leave CVM cluster mirror interface connected to 10G vswtich. networking design is the key things.

CVM cluster and ESXI mgmt&production network consideration

Hi guys， two basic questions: 1)can cvm cluster and ESXI data use the same 10g switch with no performance penelty ? (I have only one pair of 10g switch, and NX1065 one dual port card. As we know, cvm cluster must use 10g network, but I`d like also to use 10g for ESXI data network. ) 2) generally ESXI mgmt(usually,vmkernel port for NFS access) is on the same 10g link with cvm cluster(also CVM prism mgmt), If the user`d like to have a separate uplink or subnet for ESXI MGMT, is it ok ? I`m worried about the performance problem. thanks in advance !

Which software version should select ?

Hi Folks, For Nutanix product, Is it a best practice to have the latest software version (e.g AOS,NCC) installed, No matter first-time installation, or upgrade. Some venders may advise just install the slightly lower version then the newest. My real user case: we installed NX 2 months ago, and plan to put it into produciton these days, but two new AOS version has been available on Portal.nutanix.com, So Can I update AOS to the newest one ?

Unable to vmotion svmotion between clusters

We are fairly new to Nutanix. We have two seperate clusters in seperate datacenters. Our goal is to be able to move workloads between clusters based on needs and resources. We are using VMware 5.5 and everything seems to work as planned with the exception of the moving from cluster to cluster. We have cluster A and cluster B. We are using metro availability to sync the data from cluster A to cluster B at this time and that seems to work correctly. When I attempt to perform a cold migration from cluster A to cluster B I get the following error:Relocate virtual machineArtemisCloneFile/vmfs/volumes/ec936530-956aa-9ac/ArtemisClone/ArtemisClone.-vmdk was not found cold migration from cluster B to cluster A works fine. the whitelists are identical on both clusters. VMWare isn't really much help as their reply is to just browse the datastore and add it to inventory on a server in cluster B

Downgrade NOS version

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

ECX error & disk id & svmotion

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

Added 10Gbps HBA to Server for CE. Do I have to reload my CE Instance or is there a way add driver?

I have a T20 server with 32GB of RAM and just added a cheap melonox 10Gbps SPF NIC to my nutanix box. I would really hate to reload everything and lose all my data. Do I have to reload the CE Instance or is there a way to load drivers or update to see the NIC. The last thing i want to do is blow it away and the card isnt even supported.

Mount datastore on all host via REST API

My request : {"name": "MyContainer","storagePoolId": "777""compressionEnabled": true,} I have tested to add the parameters"nfsWhitelist": ["esxi1",esxi2","esxi3"] with the ip of the ESxi but it doesn't work. Maybe the parameter mappedRemoteContainers (java.util.Map, optional), but i found no documentation on that. Have you an idea ? Thanks Alban

Setting up cluster with no DNS and no NTP ?

Hi, I'm implementing Nutanix AHV at a customer in a bunker environment. There is no internet access, and the infrastructure will have minimal to no LAN communication outside of the cluster infrastructure. The customer expected to use IP and shot names based on hosts files instead of DNS resolution. Unfortunately, on Foundation, there is no way to setup the cluster with no DNS. And I guess NTP will be the same, but I didn't get there. Any workaround ? Or are NTP and DNS mandatory for the cluster to work ?

From 4.5.2, upgrade to 4.6.2 ? or to 4.5.3 and wait a while ?

Hi, Just implementing new xc630 clusters with AHV. From factory, 4.5.2 is implemented. I know 4.6.0 and 4.6.1 have got some glitches. Some of my collegues are a bit reluctant to upgrade to 4.6.2. From my PoV, it should now be safe... What would be the recommanded course of action ? Upgrade to 4.6.2 a keep 4.5 and go to .3 and wait for feedback on 4.6.2 ?

difference between Phoenix, NOS, AOS

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

Hi Guys, Is there a difference between 512n or 512e with Nutanix? Vmware doesn't support 512e but vendors are quoting 512e with their config. Any difference in performance? Is one better than the other?

basic capacity calculate and RF question

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)

Which is the final/official tool to confirm supported hypervisor version

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 ?
