DISPATCH INSTRUCTIONS

WHAT SKILLS DOES THE FIELD ENGINEER/ADMINISTRATOR NEED?:
SE3000 series training. Use normal ESD procedures.

TIME ESTIMATE: 30 min

TASK COMPLEXITY: 2

FIELD ENGINEER/ADMINISTRATOR INSTRUCTIONS:

PROBLEM OVERVIEW:
A disk has failed in the 3120 SCSI array.

WHAT STATE SHOULD THE SYSTEM BE IN TO BE READY TO PERFORM THE RESOLUTION ACTIVITY?
The array should be powered on.

WHAT ACTION DOES THE CUSTOMER NEED TO TAKE:
None.

WHAT ACTION DOES THE ENGINEER NEED TO TAKE:

IMPORTANT

Before changing the disk, check that there aren't any dependencies to other applications accessing the disk, and if there are, take them into account before considering replacing the disk.

In order to check these dependencies, please consult the Doc ID 1006405.1: " Quickstart Reference for Sun Storage disk replacement".

After eliminating all risk, please go through all the steps described below:

A. Identifying the Defective Disk Drive

Caution - To prevent any possibility of data loss, back up data prior to removing disk drives.

1. Examine the back of the array, and record the cable connections.

2. Physically locate the defective disk drive.

An amber LED next to a drive on the front panel of the JBOD indicates a failed disk drive.

Caution - Failure to identify the correct disk drive may result in replacing the wrong disk drive and could cause a loss of data. Be sure that you have identified the correct disk drive. It is strongly recommended that you back up the data prior to removing disks.

3. Record the Chl and ID number for the defective disk drive. The ID on the back of the array will match the disk target number.

For descriptions of ID settings, see the picture below:

4. (Optional.) In Sun StorEdge Configuration Service, a red icon in the main window indicates a JBOD drive failure. Review the error log to confirm the disk drive ID for the failed drive. For details on the Sun StorEdge Configuration Service main window, see Monitoring with Sun StorEdge Configuration Service.

5. (Optional.) In Sun StorEdge CLI, run the show enclosure-status command. If the drive status is "Absent" the drive may have failed, or has been removed from the chassis.

B. Removing the Defective Disk Drive

Remove the defective disk drive with the following steps.

1. Unlock the locks with the provided key, and gently pull the plastic front bezel away from the front of the unit so that it drops down and is supported by the two hinged brackets on the sides.

2. Turn the thumbscrew counterclockwise several full turns until the thumbscrew and drive module are loosened.

3. Gently pull the release handle upward.

4. Pull the drive module out until the drive connector has fully disconnected from the midplane.

5. Wait 20 seconds for the drive to stop spinning and then remove it from the chassis.

Please see the picture below to have the front view of a disk drive when preparing for the replacement:

C. Installing the New Disk Drive

To install the replacement disk drive, perform the following steps.

1. Gently slide the drive module into the drive slot until the handle pins slip into the chassis notch.

2. Lower the disk drive handle until it is vertical.

3. Press and hold the drive handle in while you press the thumbscrew in until it engages the threads.

4. Turn the thumbscrew clockwise until it is finger-tight.
Note - To ensure that a thumbscrew is finger-tight, tighten it with a screwdriver and then loosen the thumbscrew counterclockwise a quarter turn.

5. Push the plastic front bezel onto the front of the unit until it is seated firmly, and use the key to lock the locks. A green drive LED indicates a functional drive. 

6. Perform any operations your host software requires to discover the new drive and bring it under software control.

7. (Optional.) If you are using Sun StorEdge Configuration Service, you can discover the new drives using the software.
