Promiscuous Mode

This Mode is available in both type of switches: i.e
1.Standard Switch
2.Distributed Switch

In Standard Switch, policies can be configured at two levels:

In the above figure, I have 3 machines of fedora named as F1, F2, F3 .

- F1 & F2 resides on the same port group.

- F3 resides on the different port group.

I have made PROMISCUOUS MODE as enabled on VM Port Group.

- In F2 machine, I have made a ping  www.google.com

-In F1 machine, i will be able to listen to the traffic by using tcpdump -i src eth0 IP 

You are running VMware ESX through an incompatible hypervisor. You cannot power on a virtual machine until this hypervisor is disabled

This error is there when I created an ESXi host in a cloud for the test lab and when I tried to power ON a virtual machine I got this error.

In order to resolve this issue,
1.Enable SSH on your host.
2.Navigate to /etc/vmware/config  file of the ESXi host.
3. vmx.allowNested = "TRUE"

After this, the issue will be resolved.

NOTE: This is my test environment, strictly not recommended in production environment.

Air Watch

It is probably going to be the next big thing for the enterprises.
Tested this solution on my Apple iPhone and the way you can manage the devices is deep inside. It supports many types of mobile operating systems. The two major market vendors of mobile operating systems i.e iOS and Android both of them are supported.
What you can customize is starting from the settings to the apps that show of on your corporate device with just a click.

I have tested this product on my apple device and with just a single profile i have removed the camera and all its related apps from my iphone.

Here is a screenshot of my mobile when i configured airwatch on my mobile device.

Stay tuned to learn more.

Error ORA-01031

This problem I have came across when i was trying to configure Oracle 11g as an external database for vCenter Server deployment which i have somehow resolved.

Everytime you try to explicitly grant permission to a user you get this error ORA-01031 : insufficient priviledges.
In order to resolve this issue you have to look out for a file named sqlnet.ora in your system where you are trying to install this ORACLE 11g.
NOTE: This one solution worked for me.

Just open this file in notepad and close it and now try to login to the SQL*PLUS with the credentials of sysdba i.e

And after that try to grant the permissions to the user and you will be done.
In my next blog post will share after successful creation of database, will share USING EXTERNAL DATABASE as ORACLE 11G.

Step by Step Upgrade of VCSA 5.5 to VCSA 6.0

1. Mount the ISO and click on vcsa-setup.html . The upgrade and install button will only be displayed if you have installed client integration plugin. Once it is displayed on the web browser click on UPGRADE

 2. Installation wizard will start as soon as you click on yes.

3. Accept EULA

 4. Choose the target server on which to deploy this upgraded VCSA

5. Here starts the upgradation tasks where you have to provide the information of existing vCenter Server and ESXi host where this vCenter Server resides along with the information of Single Sign On Domain.

6. Here now you can modify the size of deployment. As this is my test environment so i have kept it tiny with minimum configuration.

7. Review the information and click on finish. It will get upgraded.

EMC vVNX (Software Defined Storage)

DEPLOYMENT & CONFIGURATION

• Virtual VNX (vVNX) is a software stack that provides many VNX features. It allows VNXe software to be available as a downloadable virtual storage appliance (VSA) for use with a VMware ESX or ESXi hypervisor. 
• Most of the folks who wants to test the new feature of VMware for the Software Defined Storage i.e VVOL like most of us have came across so far can test with the help of this solution by EMC ie.  VVols technical preview for vVNX from their website.
• It is available as an OVA (Appliance )which requires
     -M inimum RAM or what i can say from my observation is exactly 12288MB (12GB)
     -Disk format for this appliance by EMC is Thick Provision Eager Zero.
     - 2 CPU
• For the first login USERNAME & PASSWORD for login into terminal for verifying the settings is service\service but in order to access the Unisphere USERNAME:admin, Password: Password123#.

• In my next post i will share how you can create a storage pool, LUN, NFS & vVOL.

vSphere Data Protection Part 2

In vSphere Data Protection we have shown the minimum requirements , how to deploy vDP and configure.

Now in this post i am going to share how you can restore the virtual machine and perform the file level recovery.


1. Once vSphere Data Protection is configured , you will find its plugin in here.

2. Click on this vDP

3. After that a job is required in which we get an option to select the particular virtual machine, datacenter or partiicular hard disks of a virtual machine. 

4. We have to specify the job schedule time and retention policy. By default the retention period is of 30 days and could be customized. 

5. In order to restore the machine to a previous backup point, just go to Restore tab and choose the machine and the point where to restore. 

6. Another feature of vSphere Data Protection is, it provides file level recovery. For that you have to login into the operating system and then onto the url of file level recovery i.e.
