Configuring a Hard Disk
Use VI Web Access to edit hard disks in virtual machines.
To edit the hard disk configuration on an ESX 3 virtual machine
- Make sure the virtual machine is powered off.
- From the VI Web Access client, select the virtual machine.
- On the Summary tab, under Hardware, click Hard Disk.
- To edit the configuration on an existing hard disk, click Edit.
- Select the SCSI Device Node from the drop-down menu.
If the hard disk you are configuring is the boot device for this virtual machine,
click Modify the Device's SCSI Node to change the SCSI device node.
- Choose whether to use the disk in Independent Mode.
- If you chose to use the disk in Independent Mode, select Persistent or Nonpersistent disk mode:
- Persistent - Disks in persistent mode behave like conventional disk drives on your physical computer. All data written to a disk in persistent mode is written out permanently to the disk.
- Nonpersistent - Changes to disks in nonpersistent mode are not saved to the disks, but are lost when the virtual machine is powered off or reset.
Nonpersistent mode is for users who always want to start with a virtual machine in
the same state each time. Example uses include providing known environments for software test and technical support users, as well as demonstrating software.
- Click OK.

- Undoable - Changes to disks in undoable mode can be saved, discarded, or appended when the virtual machine powers off.
- Append - Changes to disks in append mode are preserved in a redo log attached to the virtual disk.
- Click OK.
