What is Nutanix Volumes?

Volumes acts as one or more targets for client Windows or Linux operating systems running on a bare metal server or as guest VMs using iSCSI initiators. Do not use Volumes to create an iSCSI datastore to Hyper-V or ESXi hosts. This configuration is not supported.The iSCSI data services IP acts as an iSCSI target discovery portal and initial connection point. The client only needs this single IP address to help load balance storage requests and provide path optimization in the cluster, preventing bottlenecks.Enable Nutanix Volume Get the client IP address that you will add to a volume group client whitelist. Create an iSCSI data services IP address for the Nutanix cluster. This address cannot be the same as the cluster virtual IP address. Provision storage on the Nutanix cluster by creating a volume group consisting of one or more vDisks. Perform an iSCSI target discovery of the Nutanix cluster from the clients. [Optional] Configure CHAP or Mutual CHAP authentication on the init

Enabling Load balancing of vdisks in a volume Group

AHV host supports load balancing of vDisks in a volume group for Guest VMs. Load Balancing of vDisks in a volume group enables IO-intensive VMs to use the storage capabilities of multiple CVMs If you enable load balancing on a volume group, the guest VM communicates directly with each CVM hosting a vDisk. Each vDisk is served by a single CVM. Therefore, to use the storage capabilities of multiple CVMs, create more than one vDisk for a file System and use the OS-level striped volumes to spread the workload. This configuration improves and prevents storage bottlenecks. vDisk load balancing is disabled by default for volume groups that are directly attached to the VMs. You can attach a maximum of 10 load balanced volume groups per guest VM. For Linux VMs, ensure that the SCSI device timeout is 60 seconds.  Procedure: SSH into the CVM as a nutanix user Do one of the following Enable vDisk load balancing if you are creating a volume group acli vg.create vg_name load_balance_vm_attachm

Collect Nutanix PD Snapshot

Hello everyone, After some research i saw that there is no opportunities to collect Total Snapshot Usage (Exclusive Usage) per Protection Domain through the API (i’m on 5.15.3 AOS).As i have lot of VMs per PD, how can i collect this info through Nutanix Cmdlets and obtain this one per PD ?  Thanks.

how to change the ssh control for CVM

Hi I have a question in the Nutanix enviroment.I need to change control for the ssh to CVM so that just some IPs can access to avoid some intrusion access.I checked the <Nutanix security Guide> and there are some descriptopm in TCP Wrapper Integration, But after I changed the file of /etc/hosts.allow to include just the allowed IPs and CVM management subnet. But It will be changed to default after the cluster security config schedule(by default daily.) Is it possible to change the sshd allow list to achieved this goal? there are security requreiments for the enviroment. thanks.

Changing default gateway for CVM/AHV

Hi everybody,We’re doing a slight restructure in our DC and in thus need to change the default gateway used by a Nutanix cluster (3-node cluster).I’m aware of the following guide:https://portal.nutanix.com/page/documents/details?targetId=Advanced_Admin-Acr_v4_6:ip__ip_reconfig_web_c.htmlBut isn’t it at all possible to change something as simple as just the Default Gateway without such an invasive procedure requiring downtime?The part of the article on how to do it manually is...Non-existent:https://portal.nutanix.com/page/documents/details?targetId=Advanced_Admin-Acr_v4_6:ip__cvm_ip_address_reconfigure_t.html

Setting NIC speed

Hi community, I have some Qlogic 10G/25G NIC cards in my cluster which as I understand are not “supported” however seem to be detected correctly to some extent. Manage_ovs show-interfaces displays the output below which leads me to belive that the driver is loaded. However, currently those ports are connected to a 10G switch and so the speed and the operational status are not correctly working. Is there a way to set these by hand?  manage_ovs show_interfaces    name  mode  link speedenp5s0f0 25000 False  Noneenp5s0f1 25000 False  None    eth0  1000 False  None    eth1  1000 False  None    eth2  1000 False  None    eth3  1000 False  None    eth4  1000 False  None    eth5  1000 False  None    eth6  1000 False  None    eth7  1000  True  1000 When I add those cards to a vritual bridge I get the error message below. manage_ovs --bridge_name br1 --bond_name bond1 --interfaces 25g update_uplinks2021-03-31 18:05:50,402Z WARNING manage_ovs:437 Interface enp5s0f1 does not have link state2021-03-

NGT Upgrade messages - what do they mean

Good morning All   I have a bit of an NGT issue, the Prism Central alerts me to say some VMs need a NGT upgrade, when I go to upgrade them I see the message “NGT can only be upgraded on 0/1 VMs which have the available upgrade of NGT”   Review and confirm buttons are greyed out so I cannot continue - what does the message mean and what do I do to get it to work?   Many thanks   Eric

HiI have 4 Nodes cluster with the detailed network belowVLAN1000 : IPMI Usage (192.168.255.x/24)VLAN20 : GuestVM & Internal Cluster Network (192.168.2.x/24)I was using eth3 and eth4 in bond br0-up in bridge br0 (vs0) And then i’m adding a new vlan (VLAN30 : 192.168.3.x/24) for separating GuestVM network from Internal ClusterI am using eth0 and eth1 in another bond (bond br1-up in bridge br1) connected to my switchport mode access VLAN30. The problem is, when i created VM using that network (vs1), my guest vm cant ping anywhere even the gateway of its subnet. But when i test my laptop that connected to the switchport mode access VLAN30, my laptop can ping the Gateway.Here i give the detail of my topology and uplinks configurationTopologyUplinks of each hostsvs1 configuration Perhaps someone can enlight me maybe i missed something here when i’m trying to configure this? Thank you.

Quick Restore in case of failed ESXi upgrade?

Hi!I am wondering, if there is a quick way to restore from a failed ESXi upgrade.Imaging you have fired up a ONE-Klick-Upgrade of the ESXi image, and (as see with ESXi7.0U1GA) the hypervisor is not boot up again.At ESXi level i can backup config and restore config after a plane install. But what about CVM?Setting up the whole node with foundation is a nightmare, if the node is already installed in an customer environment, and can’t be discovered.The best way would be, that the foundation within a cluster could deploy a CVM to a plain ESXi and rebuild the cluster-node from the information stored in the cluster...

shrink VM disk

HI Team under Prism we’ve created a few VM’s (windows), one of VM is our File Server, current configuration is IDE disk 1TB, (60GB OS, 900GB shared folders). probably is better to create one virtual disk 60GB on OS and the second virtual disk as storage (1TB) or more.question is how to shrink current IDE disk from 1TB → 60GB, and if IDE should be change on SCSI disk, what Nutanix recommended?instruction to shrink disk IDE->SCSIthanks Dariusz

How to create CG in a given PD (Metro)

Using the Nutanix CMDlets it turns out that out of the 7 protection domains in my cluster, one has only 1 Consistency Group assigned to it, which protects over 1200 files. (Almost 4000). How can I create a few CGs within a given PD so I don’t get the threshold alert in the future?

Dark site upgrade

Hello all,I am trying to do some updates in a dark site. I have configured the webserver and downloaded all the updates on the local server(like in the documentation). But from my understanding of the documentation, you need to do the following steps:Put the necessary files in the web server Replace the compatibility checks for the specific upgrade module Run inventory checks. Upgrade moduleI find it quite hard and time-consuming to do this for each component. Are there any better/faster ways to upgrade a dark site?For example, download all the upgrades and perform only one inventory check?

Hi All,I have a HP GL380p G8 and I have 1x30GB SSD 1 x 400GB SSD 2 x 600 SASWhen i start the install it asks for the location to install the hypervisor, CVM and what are data disks.  Can I use the 30GB SSD for the hypervisor and the CVM. This will leave the 400GB SSD for performance tier and the 2 x 600GB for normal tier.

AHV Node failed during LCM

I recently used LCM to update the firmware on my 9 node cluster. One of the hosts did not come back up. I was able to get it to reboot back into the host OS, but it had no network connectivity. The interfaces were up, IP address assigned, just no traffic passing through the bridge. After fighting with it for some time, I decided to eject the node from the cluster and just re-foundation a new one. I initiated the removal process, but the node status remains in MARKED_FOR_REMOVAL_BUT_NOT_DETACHABLE:nutanix@NTNX-<REDACTED>-A-CVM:10.1.153.30:~$ ncli host ls id=21    Id                        : 0005adca-5f30-1bf1-0000-000000008d15::21    Uuid                      : 705089f7-2435-4a35-83fe-603470bd36d6    Name                      : 10.1.153.15    IPMI Address              : 10.1.151.249    Controller VM Address     : 10.1.153.34    Controller VM NAT Address :    Controller VM NAT PORT    :    Hypervisor Address        : 10.1.153.15    Host Status               : MARKED_FOR_REMOVAL_BUT
