You can easily update your vCenter Server Appliance (VCSA) offline by downloading a product patch ISO and via the CLI.
Download the latest patch from VMware Patch Download Center. Select VC from the Search by Product drop-down menu, then select the correct version (i.e. 6.0 or 6.5). Download the patch ISO and attach it to the VCSA.
Log in to the shell (using SSH or VMRC) and initiate the update:
software-packages stage --iso
software-packages list --staged
software-packages install --staged
After the update has finished, you will have to reboot the VCSA.
You may have noticed that running the VMWare vSphere client on a display with higher DPI settings causes problems with the mouse cursor alignment when working inside a VM. This is because of a mismatch between the DPI settings of the VM and the DPI settings of your computer.
To resolve, right-click the shortcut to the client, go to the Compatibility tab, and enable Disable display scaling on high DPI settings.
The downside of this method is that there will be misalignment of some parts in the client, but it is still workable and moreover, it solves the mouse issue in a VM.
When attempting to install or upgrade VMWare vServer server or its components, you may get the following prompt:
Please insert the Disk: 1
If you click OK, the message reappears. Clicking Cancel results in the installation to roll back.
Copy the entire installation files to a location on the local hard drive and run the install/upgrade from there.
When running the installation from the local hard drive, and you get the error Provided password is wrong or empty, reboot and re-run the install from the local hard drive.
