4.2 How to Install a Disk Drive
The system’s disk hot-plug feature lets you install a disk drive without shutting down
the operating system or turning off the system power.For more information, see
your Sun Enterprise 220R Server Owner’s Guide.

4.2.1 Before You Begin

Complete this task:
Section 2.8 “How to Avoid Electrostatic Discharge” on page 69
Note - If the server is setup without a local graphics console, terminal, or monitor,
you need to set up one ofthese options in order to issue software commands. See
“About Setting Up a Console” on page 40for further information.

4.2.2 What to Do

1. Prepare the system to receive the new disk drive.
The hot-plug installation procedure involves software commands for preparing
the system prior to installing the disk drive. See your Sun Enterprise 220R Server
Owner’s Guide.
2. If you are not hot-plugging the disk drive, halt the operating system and turn
off system power.
See Section 2.1 “How to Power Off the System” on page 54.
3. Push the disk drive latch to the right to release the disk drive handle.
