Hello All ,


This is in continuation to my Blog series on vCF 3.9. Hope you enjoy reading it.


1.     vCF Series – Bring UP (VMware Cloud Foundation 3.9) – vmWARS

2.     vCF Series – Commission & Expand a vSAN Cluster(2) – vmWARS





Some time it happens that NIC is not coming up automatically if it flap multiple times on ESXi . For example during the code upgrade of network switches which generally up and down the link connection more than three times. Some NIC card status not come up in these situations as ESXi mark them disabled due to multiple flaps.

And even The esxcli network nic down/up commands fail to restart a NIC.

Errors that will be reported in the vmkernel.log file:

2013-10-23T05:41:42.588Z cpu36:10220)Uplink: 8603: Setting link down on physical adapter vmnic7.

2013-10-23T05:41:42.588Z cpu36:10220)Uplink: 8634: Requested link speed/duplex 0x9c4/0x2 is not valid.


Login to the ESXi via SSH & Use these commands only with the network cards running auto negotiation 10Mb /100Mb /1000Mb/10000Mb speeds.

  • To change the link state of the physical interface to down:esxcli network nic down -n vmnicX


  • To auto-negotiate the speed of an adapter:esxcli network nic set -n vmnicX -a
  • To change the link state of the physical interface to up:esxcli network nic up -n vmnicX

While Doing this in the above mentioned sequence the NIC Link will come UP.

Hello Folks,

So here we have another topic in  to integrate the vROPs Manager with active directory. The steps mentioned below will guide, how to use your name as a username after integrating the vROPs with Active Directory of Microsoft.


Note -Select the Local User from top drop down menu

  • Click on Administration Menu and expend Access in left Panel.
  • Select Authentication Sources and select AD Source which you have integrated earlier. If not added earlier then Click on + icon and add AD Source.
  • To Edit AD Source, Click on pencil icon in right side.


  • In Source window, Click on Details highlighted below.


  • Here you will get two options (samAccountName & userPrincipleName) in Common Name drop down menu.


  • You need to choose Common Name as samAccountName if you want to login using short account name rather than email ID.


That’s all, Now from the logic screen you will get the another name on the top drop down menu, where Domain name also appears, select the domain, enter username and password of domain user, here we go -authenticated by AD.

The upgrade process of vRealize Operations is consists of two steps in series.

  • Enter Admin Credentials and Login to Admin Interface.

  • Wait when an upgrade is completed. It will take some time to complete the OS Update.
  • Once OS update will be complete, Cluster status will be in Online state.
  • Now OS Upgrade has been completed. Now move to Phase 2 to upgrade Virtual Appliance.


Phase # 2 - Upgrade Virtual Appliance

  • Go to Administration Panel and Click on Software Update.

  • Provide Admin Credentials and login to Admin Interface console.

  • Wait when an upgrade is completed. It will take some time to complete the Virtual Appliance Update.
  • Once VA update will be complete, Cluster status will be in Online state.

Data Virtualization

Posted by HarjitSB Dec 14, 2016

Hello everyone,

Myself Harjit Singh. I am not the regular blogger but a serious reader to the information which making changes in the industry. I have gone through many blogs, posts and discussions and found that walking alongside the change for an industry is the only way to success. The world of IT is ever changing, and with the turn of every New Year IT teams around the world seize the opportunity to examine the latest technology trends and how they might be able to adopt them for their own organizations.

There are many trends which influence the Industry like Big Data, Data Virtualization or Cloud computing, IT Security and none other than IOT. Since data is genuinely at the core of all trends, virtualization of Data center remains in lime light.

There are many competitors in the market for DC virtualization but VMware being one of my favorite has dominated the market. It has proved the actual sense of DC virtualization and since last few years it has become the no. one in Data virtualization which is known as cloud computing.

Data virtualization which actually the need of today is decouples data from its underlying infrastructure for increased agility and reliability of the data. Virtualized data can be made seamlessly available any time anywhere across the entire IT spectrum – from traditional data centers to SaaS and private, hybrid, or public cloud structures. Cost and complexity are greatly reduced. Through incremental data capture and management of a single physical copy, unlimited virtual copies can be made available anywhere for instant access. Enabling companies also for a smooth transition to the cloud. A finely tuned central SLA console defines access rights, recovery and retention policies on an application level.
