Enterprise Linux - add hard drive

Here are the procedures to add a new hard drive for vSphere (VMWare ESXI 4.0.0) virtual machine.

• vSphere Client -> virtual machine “Summary” tab -> "Edit Setting" -> Virtual Machine Properties panel “Hardware” tab -> click "Add" -> popup a "Add Hardware" panel
• "Add Hardware" panel -> select "Hard Disk", click "Next" -> select "Create a new virtual disk" (by default), click "Next" -> select "Disk Size" to 8GB, click "Next" -> select "Virtual Device Node SCSI(0:1)" (by default), click "Next" -> click "Finish"
• click "OK" on "Virtual Machine Properties" panel
• vSphere Client -> virtual machine “Summary” tab -> "Refresh Storage Usage"
• reboot virtual machine
