I've been using VMWare for a while now and I always get asked some common questions about it. One of those is how to add a new virtual disk to a Linux virtual machine. So in response to that, here are the steps to adding a new SCSI based virtual disk to a CentOS Linux virtual machine. The steps for adding a disk to a Windows machine is very much the same except you would use the Disk Management utility from the Control Panel.
Step 1: Open virtual machine settings
Select your virtual machine, as you can see from the photo I selected the Infrastructure virtual machine. Next press the "Edit virtual machine settings' to open the Virtual Machine Settings dialog.
