                    Yesterday, I was working into my vsphere Lab where I have deployed one virtual machine into the environment. After deployment virtual machine was working perfectly fine. After some time, I have added 2 huge hdd of size 800 GB using PVSCSI. Once I added the hdd into the VM, and after accepting the change, I tried to open the console and found vm has rebooted and stuck at "Operating System not found" That’s look wired, as I have just added the hdd online and suddenly it rebooted and stuck at this stage. To troubleshoot this issue I tried to gracefully shutdown the VM and tried to bring online in hope, it will detect the changes, but again it stuck at same level "Operating System not found" I checked my OS drive which is  created with the LSI SCSI controller, and the 2 new hdd I created with PVSCSI controller. Here is what the problem exists!!!!! Basically, When the virtual mach...

Virtual Volume (VVols) is basically a latest introduction into Vsphere 6.0 environment which has significantly change the architecture of storage part. Traditionally into vsphere environment we are having a concept of LUN to provide storage into ESXi into which VMware administrator used to provision virtual machine into that peace of storage (LUN). In this process all vm’s which are deployed are depended into that LUN having dependency into it. Like, if that LUN having any issue like all path went down or its loosed its connectivity from ESXi or storage, into this case all its derivative vm’s will get affected. That dependency has moved out into VVol VVol has introduced where virtual machine is directly connected to SAN (Raw area of storage), not on LUN concept.  Architecture of VVol In Virtual Volumes storage has altogether changes compared to old architecture of Vsphere. VVols completely change the way storage is presented, managed and consumed and certainl...

Whats New in VMware Vsphere 6.0

Last week I got into an issue of one of my client into Vsphere environment where one of its ESXi went done out of the network.

What I found is its VMkernal switch got removed due to unexpected reason. So to resolve the issue I tried to reconfigure its vswitch0 (vmk0) by going into Tech Mode of that Exi. Below are the steps which I followed to resolve the issue. 1) Login to ESXi 2) Press F2, Check if you " Configure Management network " is greyed out or not" if yes,    follow below 3) Press ALT+F1 to move the ESXi screen to tech mode   ( This is command line like dos) 4) login with root account 5) Run the following command into it esxcli network ip interface add --interface-name= vmk0 ...
