The VMware OVF Tool is implemented by VMware for easily importing and exporting virtual machines in Open Virtualization Format (OVF) standard format. Here, I want to show you how to download and install it, and then how to use it from a Windows machine.

Edit the DNS or IP Address Settings of the VCSA 6.x

1
The DNS setting is essential for the vCenter Server Appliance deployment. If you omit its configuration, you will fail the installation. Every production environment must have a DNS service running in the infrastructure, and are those DNS setting the one you use for your deployment. But, there is a chance that you have a test environment or home lab...

Troubleshooting

Unable to delete inaccessible datastore

Unable to delete an "inaccessible" datastore

I was switching my storage array, so I migrated the VMs from that old datastore/storage to a new datastore/storage. The old datastore was shared by 3 ESXi hosts, no cluster. After migrating the VMs and unmount/delete the datastore, it was still presented in two of the ESXi hosts and was marked as inaccessible.

WinSCP VCSA

Unable to Access the VCSA 6.7 via WinSCP

9
One of the many and easiest ways to get the logs from the ESXi hosts and vCenter Server Appliance (VCSA), is accessing directly to the files directory using tools such as WinSCP, which helps to transfer the files between a local and a remote computer ( Ex. VCSA). I never have had issues with the ESXi hosts and WinSCP, however, trying to access the VCSA is a different story.
