Legend LED Symbol Color Lights When... 1 OK to Remove Blue A disk drive can be removed safely during a hot-plug operation. 2 Service Action Required Amber The system is running and the disk drive is faulty. The front and rear panel Service Action Required LEDs are also lit if the system detects a disk drive fault. 3 OK/Activity Green Drive is properly inserted into the system. LED will flash off and on when the drive is being accessed.

3.1.2 Removing and Installing Disk Drives and Disk Drive Filler Panels

Use the following procedures to remove and install disk drives and disk filler panels from the server.

Remove a Disk Drive Filler Panel

1. Attach an antistatic wrist strap.

   See 2.3 Performing Electrostatic Discharge and Static Prevention Measures.

2. Identify the disk drive filler panel you want to remove.
3. On the disk drive filler panel you want to remove, push the release button to open the latch.
4. Grasp the latch and pull the filler panel out of the drive slot.

   ---

   Caution - The latch is not an ejector. Do not bend it too far to the right. Doing so can damage the latch.

   ---

   ---

   Caution - Whenever you remove a disk drive filler panel, you should replace it with another filler panel or a disk drive; otherwise, the server might overheat due to improper airflow.

Remove a Disk Drive

Refer to Removing a Disk Drive when completing the following procedure.

1. Attach an antistatic wrist strap.

   See 2.3 Performing Electrostatic Discharge and Static Prevention Measures.

2. Identify the disk drive you want to remove.

   The amber Service Action Required LED on the drive might be lit.

   See 3.1.1 Disk Drive Status LED Reference.

3. Determine whether you can replace the disk drive using the hot-plug procedure or whether you need to power off the server and use the cold-swap procedure.

   A cold-swap is required if the disk drive:

   • Contains the operating system, and the operating system is not mirrored on another drive
   • Cannot be logically isolated from the online operations of the server
4. Do one of the following:
   • To cold-swap the drive, power off the server. Complete one of the procedures described in 2.6 Powering Off the Server.
   • To hot-plug the drive, take the drive offline. This removes the logical software links to the drive and prevents any applications from accessing it. For information on how to take a disk drive offline, refer to the Sun Disk Management Overview (820-6350).
5. On the drive you plan to remove, push the disk drive release button to open the latch.
6. Grasp the latch and pull the drive out of the drive slot.

   Caution - The latch is not an ejector. Do not bend it too far to the right. Doing so can damage the latch.

2. Verify that the release lever on the disk drive is fully opened.
3. Slide the drive into the drive slot until it is fully seated.

4. Close the latch to lock the drive in place.
5. Do one of the following:
   • If you have cold-swapped the drive, restore power to the server. Complete the procedure described in 6.3 Powering On the Server.
   • If you have hot-plugged the drive, configure the disk drive. Refer to the Sun Disk Management Overview (820-6350) for information.

Install a Disk Drive Filler Panel

1. Verify that the release lever on the disk drive filler panel is fully opened.
2. Slide the disk drive filler panel into the drive slot until it is fully seated.
3. Close the latch to lock the filler panel in place.
