Failed to start the virtual machine

                          When you try to Power On a virtual machine, you will receive the below error:

“Failed to start the virtual machine.
Module DevicePowerOn power on failed.
Unable to create virtual SCSI device for scsi…”
Cause

You might have tried to PowerOn a VM with ESXi incompatible vmdk file. This VMDK file will be compatible only with VMware workstation, VMware servers etc and not with the ESXi.

Resolution

Make the vmdk file compatible with ESXi.

Steps:
- Remove the vmdk file from the VM. (Only from the VM!!!)
- Connect to the ESXi box using putty
- Execute the below command to convert the existing vmdk file to new ESXi compatible vmdk
vmkfstools -i existing_vmdk_location new_vmdk_location


- Point the VM with the newly formatted vmdk file and Power On. That’s it….

VMware and Windows Interview Questions: Part 3

What is vSAN ? It is a hypervisor-converged storage solution built by aggregating the local storage attached to the ESXi hosts managed by a vCenter.  Recommended iSCSI configuration? A separate vSwitch, and a separate network other than VMtraffic network for iSCSI traffic. Dedicated physical NICs should be connected to vSwitch configured for iSCSI traffic. What is iSCSI port binding ? Port binding is used in iSCSI when multiple VMkernel ports for iSCSI reside in the same broadcast domain and IP subnet, to allow multiple paths to an iSCSI array that broadcasts a single IP address.
