NearSync not working for a particular VM

Hello everyone,I started a new project in which we need to be prepared for a Disaster Recovery between 2 Nutanix clusters in different regions. I did the Data Protection from Prism Central just fine in the beginning, already have 8 VM with NearSync enabled with RPO of 15min. However, this new VM has been giving me trouble lately, giving me a RPO up to 3 hours because of the following issues: Warning : Snapshot Replication to Remote Site is Lagging.Warning : Snapshot queued for replications to remote siteWarning : Entity is being transitioned to a lower frequency snapshot schedule. To be fair this new VM is kinda big, with 10 cores, 50GB RAM, and 1.22 TB storage used. It’s for a high transactional MSSQL Server database.I am basically stuck deciding if this is a networking problem, or a workload capacity from Nutanix problem.We are supposedly using 200MBps LAN-to-LAN networking, with a 20ms latency. Should this be enough?On the other hand, I am looking in Nutanix’s Analysis section that

Changing iLo password via command line

I know this can be done with the NX hardware using the IPMITOOL utility pre-installed, but we’re starting to use HPE hardware and I wondered if anyone knew how to change the iLo administrator login password via cmdlet? We’ve scripted this for NX line and looking to do the same with HPE’s as a part of our deployment scripting.

Hypervisor Upgrade From Windows 2012 R2 to Windows 2019

Hi Team,We have a Nutanix box SX-1065-G5 which is running with Windows Server 2012 R2 hypervisor OS. Now we are out of Nutanix support since we are having older AOS version. When we try to upgrade AOS, we cannot upgrade since new AOS will not be supported with Windows Server 2012 R2. Now we are planning to upgrade the hypervisor to Windows Server 2019, can you please advise will there be any challenges ? Since our Nutanix box is old, will it support Windows Server 2019 ?I was thinking of using AHV as the hypervisor, but we don’t have any other resource to move existing VM’s ?

Nutanix Collector 4 Error with Hyper-V

Hi. I’m trying to use Nutanix collector 4.0 to collect Hyper-V sizing information, however the following error message is displayed during the scanning phase:“Bad http response returned from the server. Code: 500. Content”I tried to use it with Remote option and locally on a cluster member and the same happens.Running the precheck script it shows these failures on the picture: The user logged in is a Domain Admin and local admin, however the script returns a failure about the user rights. Does anyone know how can I enable the “Basic auth” stated on the script output?I also tried Collector version 3.5.1 with no success.Any tips?

X-Ray応用編：VMを再利用してベンチマークにかかる時間を短縮

本記事は2020年10月05日にGary Little氏が投稿した記事の翻訳版です。原文はこちら。今回紹介するのは、ベンチマークVMの再利用、さらに重要なデータセットの再利用により、X-Rayベンチマークの実装サイクルを高速化する方法です。課題：大規模なデータセットを利用する場合、ディスク上でのデータ作成に時間がかかることがあるノードあたり2TBを書き込み、ノード間のバンド幅が10GbEであるクラスタを考えてみましょう。十分なストレージ帯域性能があると仮定すると、スループットはワイヤーバインドとなり、プリフィル（事前のデータ埋め）ステージは2,000秒（1GB/sec換算）、つまり30分以上かかることになります。モデル化されたワークロードが開始されるまでに30分も待つのは、なかなかのストレスです。ワークセットサイズが比較的小さいシナリオであったとしても、X-Rayのベンチマーク用VMのプロビジョニングとX-Rayワークロードの実行を分割することで効率化が図れます。また、VMを再利用すれば、クローン、ブート、IPの確立などのコストを避けることができます。これは、シナリオを繰り返し実装する際に非常に有効です。解決策：複数のテスト/シナリオ間でVMを再利用典型的なアプローチは、シナリオを2つのパートに分けることです。パート1：X-Rayシナリオで、VMのクローンを作成、ブートして、ディスク、データ投入を行う「デプロイシナリオ」この「デプロイシナリオ」（＝ベンチマーク用VMの準備）は一度だけ実行します。パート 2：X-Rayメインワークロードを含む「X-Ray実測シナリオ」。パート1で配置されたVMを再利用します。この2つの別々パートでデプロイ、実行されるVMを関連付けるために、Curie VM ID※の概念を使用します。 ※X-Ray（X線）にちなんで、キュリー夫妻に掛けて、X-RayでデプロイされるVM名のプリフィクスにcurieが利用されていることに由来している模様重要な注意事項「デプロイシナリオ」から"teardown"（ベンチマーク後処理）ステップを削除する「X-Ray実測シナリオ」から" CleanUp"ステップを削除する "teardown"や" CleanUp"のステップを含む「標準の」シナリオは、たとえ「id」を使用していてもVMをク

How do I stick to LTS ?

Hi everyone, I have some cluster where LCM propose some upgrade to STS version, but I want to stick to LTS. is there a way to disable some version so LCM display only “Enabled version”.by the way, there is a filter for disabled updates, so I guess there might be a way to disable some updates… Thanks for your tips and advices.cheers from the pacific islands.
