vCenter 7.0U1c and vSphere Clustering Service VMs on local or shared storage.After test upgrading vCenter from 6.5U3 to 7.0U1c (which worked just fine w 0 issues), every vmware cluster with DRS and/or HA enabled gets 3 new vCLS (very tiny VMs w 2GB storage/.13GB RAM).When NCC is ran it registers 3 WARNs that there are VMs running on the SATADOM’s. I would assume that, even what (little) they do (today), would this wear out Satadom’s or M.2’s?Would this be a concern for G4/G5’s (w Satadoms) and not G6/G7’s (M.2’s)?”While vCLS can be moved to shared storage, wouldn’t they be moved back to local storage during an NX cluster stop?(Like to point out this was done in a LAB environment, not in Production… no bits nor bytes were harmed during the upgrade progress.)
We have a very long domain name and with the current config we are using the UPN (firstname.lastname@example.org) name to login. This is becoming very irritating for me to enter the domain name each time I login. Can we configure a default domain for all the login users to use if the user didn’t mention any domain and of course if we don’t have local user by the same name?
Hello everybody, is there any advise how to shut down the whole NX Block? I got my first NX1465 and run foundation and build the cluster with AHV.After the first configuration steps i will power the whole block off to bring the NX into our datacenter. So, i didn't find a "how to". Any ideas/hints? Greetings, Maikel
I need some help. I have a HP DL380 G& that I am attempting to install the Nutanix Community version on and I have verified the hardware. I have I 240GB SSD in slot on. I have 4 500GB hd in the next 4 slots. I have put the community version on a flash drive to install. I can boot to the USB, I can tell it to install, but it then fails with the message that it can not find any drives. I am new to your program and need a little help
When trying to use the allssh "manage_ovs ...." I get the above error. As I understand it Zeus and Zookeeper are close friends(as one would expect). Zookeeper implements the cluster configuration information while Zeus is used by other cluster components to access it? Somewhere I read that when you manually add a new node to a cluster Zookeeper on that new node is not active? Any information would be appreciated (even rabbit holes). thx.
Hello Nutanix Currently, my demo cluster has had problem in removing host from cluster The host that I wanted to remove has an SSD showing status: "Marked for removal but not detachable" and it has been kept by that status for a long time with nothing changed despite that the host was shown up as successfully removed the host So, after that I have tried reinstalling this host but that status still showing up and I cannot do anything with the new reinstalled host as well as expanding the cluster with it By the way, I noted that before reinstalling this host, this host was running as a cluster member

So, on a dev cluster with Prism Central I created a Proof-of-Concept Nutanix Objects "Store". I did some experimentation (spotted a few problems with the deployment) and then decided I wanted to remove the store. First off I tried to delete the bucket, and was told "You need to delete all versions first": grr! Went and deleted all objects, but this wasn't enough, as versioning was enabled. So, turned version lifespan down to 1 day, and waited 24 hours. Great, now I could delete the bucket - however, I can't find any option to delete the store. So, I'm stuck with the (in my mind, greedy) VMs the deployment created, as I can't even go behind it's back and do anything with the VMs, as they're "special", just like the hidden Calm project which is used to deploy the store. All in all, not very impressed on first experiences...
Hi, My CVM is reporting low on disk space and trying to cleanup. I tried to follow the KB1540 and noticed the logs directory needs to be clean up. Its consuming around 8.1G the rm cmd in article dont see to apply for logs folder. Any suggestion on how to free up space under logs safely? Can i winscp and delete the logs files? Thanks CT
Executive SummaryThis document makes recommendations for designing, optimizing, and scaling Microsoft SQL Server deployments on the Nutanix enterprise cloud. Historically, it has been a challenge to virtualize SQL Server because of the high cost of traditional virtualization stacks and the impact that a SAN-based architecture can have on performance. Businesses and their IT departments have constantly fought to balance cost, operational simplicity, and consistent predictable performance.Nutanix removes many of these challenges and makes virtualizing a business-critical application such as SQL Server much easier. The Nutanix distributed storage fabric is a software-defined solution that provides all the features one typically expects in an enterprise SAN, without a SAN’s physical limitations and bottlenecks. SQL Server particularly benefits from the following storage features: Localized I/O and the use of flash for index and key database files to lower operation latency. A highly dist
We are planning a major migration from existing 3-tier ESXi over to Nutanix/ESXi (AHV to come later). Due to time constraints in our move, we are trying to optimize how many VM's can migrate at one time. VMware has a few well-known limits on their operations: vMotion operations per host (10Gb/s network) - 8 vMotion operations per datastore - 128 Storage vMotion operations per host - 2 Storage vMotion operations per datastore - 8 If I take a "one storage container to rule them all" approach, I will be limited to 8 migrations at once, as long as I spread out my migrations to 4 hosts. My target will be a 14 node cluster, so I would like to push up to 28 operations, if at all possible. Would it be considered a best-practice to carve out 4 storage containers, knowing I'm still in the same pool, and fan out the migrations to get around these limits? My goal is to saturate my 10Gbit inter-datacenter link. Yes, I like to push the limits (break things?). Would the multi-data
Good day Nutants I got a situation that I'd really appreciate your help in resolving After successfully migrating a PD to a remote site and successfully powering on the VM at the remote site, when I attempt to Migrate the PD back to the Main(Prod) Site it fails with error : critical Protection Domain XXXXXXX activate/deactivate failed and cause is listed as "Protection domain cannot be activated or migrated" Any pointers?? This PD has one CG with one VM in it (WIN SERVER 2012 with NGT installed and NGA service is running)
I've been trying to clear out a entry in the nCLI interface on a CVM without luck. tried the standard 'history -c' and 'events history clear'. Basically I have a value I dont want to show up at the propmt is a user is cycling through the "up arrow history" while in ncli. Anyone with the command?
Hi, We want to throttle replication bandwidth. In the Remote Site config in Data Protection, the option is to throttle B/W in MBps. Is this Mbps (megabits per second) or MB/s (Megabytes per second)? The unit implies megabytes per second (i.e. the "B" is capitalised), but that is normally a unit of throughput not bandwidth... Obviously there is an order of magnitude in difference so its important we interpret this correctly!
Let's say you have bought a new node(Yayy) and want to expand your cluster. Nutanix provides you with a GUI method to expand your cluster with ease and simplicity. Confused regarding the steps and the requirements before adding it to your cluster? Let's break down the queries to help you understand cluster expansion and the requirements in detail. When can you add the node in your cluster? If the node is physically present in the cluster network subnet, you can go ahead with cluster expansion. What should I check before cluster expansion? The cluster expansion process compares the AOS version on the existing and new nodes and performs any upgrades necessary for all nodes to have the same AOS version. What are the guidelines before proceeding with cluster expansion? What are the specific considerations I should keep in mind in case the hypervisor being AHV, Hyper-V or Esxi? Please go through the documentation to understand the guidelines in-depth. Cluster Expansion Guide Wh
Hello - Can someone reply with the complete power specifications for the Nutanix NX-6260 ( NX-6060 )? I know these have dual power supplies. Please provide the following at minimum: 1.) Voltage of each power supply - I think these are 208V Single Phase 2.) Amps per power supply 3.) Watts per powerr supply 4.) Power Cable Ends - Please confirm - I think these are C13/C14 for each power supply. We do not yet have the boxes so I need to prepare for the power requirements of these devices. I am looking at two of the Tripp-Lite PDU Basic 208V/240V 30A C13 10 Outlet L6-30P Horizontal 1U - MFG Part #: PDUH30HV Also wondering what others are using. Thank You. Sam
hi, in the vsphere administrative guide its mentioned to use vmware SRM along with nutanix SRA for the remote replication.if nutanix have its own replication method what is the significance of SRM? Thanks in adance. RGDS rj
Hi, We have a currently running nutanix cluster on dells and are looking to move the cvms to a new subnet. The new subnet has esxi management for each host, but on a different vmk, is it possible to point the cvms to the new vmk to get around the 'CVM subnet is currently different than the Hypervisor subnet.' issue?
