Storage Policy によるRF設定について

お世話になります。AOS 6.6以降でストレージポリシーによるRF設定が仮想マシン単位で可能になった認識なのですが、このストレージポリシーの動作と推奨について教えていただきたいです。質問①ストレージポリシーによるRF設定は仮想マシンが配置されるストレージコンテナのRF設定を上書きする形になりますか？それともポリシーに準じたストレージコンテナに自動配置されるような動作でしょうか？たとえば、RF3のストレージコンテナが1つだけ存在している環境で、ストレージポリシーによってRF2の仮想マシンを作成可能でしょうか？質問②①にて、ストレージコンテナのRF設定をポリシーで上書き可能である場合、ストレージコンテナを複数作成する必要性はないでしょうか？それともベストプラクティスとしてはストレージポリシーによる管理が可能になった最新バージョンにおいても、用途ごとにストレージコンテナを複数作成する方が良いのでしょうか？

Which goes first Host or CVM?

Newbie trying to configure Nutanix.Setup:Dell server with iDRAC VLAN’s are setup on the switch Nutanix is installed. Both the Host and the CVM have an IP address in the same VLAN (100)Questions:Should I configure the VLAN on the CVM first or on the host? It seems if I configure the CVM first I can then configure the host. If I configure the host first I can’t get to the CVM. (expected) When I configure the CVM it never seems to return so I have to hard reset the host. Setting the CVM tag back to 0 it does come back.Commands:On the host: ovs-vsctl set port br0 tag=<vlan tag> On the CVM: change_cvm_vlan <vlan tag>

New install (bare metal r820) of CE (Phoenix 6.8.1) Can't select virtual disk for CVM

Hi all, new to Nutanix here likely for the same reason a million other folk are trying it out. I’ve managed to find the download (though not exactly straight forward) for Phoenix 6.8.1 CE and am attempting to first time install on an r820 with 5 enterprise ssd sas in front bay. I’ve split the first off into it’s own virtual drive at full capacity (300something gb) for H install. The second and third off into their own individual virtual drives for CVM1 and CVM2. Then the last two combined into one virtual drive for D. I am able to select the virtual drives for H and D however the CVMS tell me it can’t be selected because the drives must be SSD which they are. Drives are fine and the virtual disks are recognized just not allowed to be selected. Any insight is greatly appreciated I’d love to test Nutanix out but documentation has been all over and even downloading (from a link in a seemingly random forum post) my confidence is a bit waned.

Cohesity Backup

Hello All,We have a Nutanix POC and I am playing around with the permissions. I am trying to create a role/category for our Cohesity backup. What entities are needed for the role. I assume cluster and VMs, but I am getting “Requested entity doesn’t exist” when trying to add the Nutanix source to Cohesity. It works fine when I add the source with a Prism Admin account. Can anyone point me to the proper permissions needed. TIA TJ

One Click Prism Central Deployment is Failing because of timeout

Hi TeamI am trying to setup Prism Central in Nutanix CE. I have configured the required details in Prism Console for deploying prism central. My deployment is failing repeatedly and getting the error saying it’s failed in tarball extraction phase. I have tried multiple times and every time I saw the issue in UI. I went through the /home/nutanix/data/logs/genesis.out logs to get more details on the issue. I found something interesting there. When we start the Prism central deployment, it first tried to download the prism central tarball and unzip it. One it’s unzipped then it’s start to convert the qcow2 file to image. when it start to convert the qcow2 → image , the command is configured with a timeout of 1800 sec. Please have a look into the below log line. 2024-07-01 08:55:17,702Z INFO 25030000 uvm.py:1606 Running cmd ['/usr/bin/timeout', '1800', '/usr/local/nutanix/bin/qemu-img', 'convert', '-p', '-f', 'qcow2', '-O', 'raw', u'nfs://127.0.0.1/default-container-40804253832490/pc.2022.

No compatible versions for deployment - Prism Central

From prism Central Element, I am trying to deploy Prism Central. When I go for create new Prism central through Prism Central Element GUI, it did not list out available versions. Instead, it just shows “No compactible versions for Deployment”. Following is what I have. I am using nutanix hardware.Version 6.8.1 - COMMUNITY LicenseNCC Version: 5.0.1LCM Version: 3.0.1.1 Not sure, how I can deploy prism central If I do not have binary. If I uncheck the option “Only show compatible versions”, it lists out following public version.pc.2023.4.0.2pc.2022.6.0.10pc.2022.6.0.11pc.2022.6.0.12 In that case, I had deployed pc.2023.4.0.2 but i never able to get GUI. I suspect the compatibility issue.Any help would be appreciated.
