Installing FRUs |
This chapter provides instructions for removing and installing field-replaceable units (FRUs) in Sun StorEdge 3120 SCSI arrays. FRU components can be replaced by customers or by Sun service representatives.
This chapter covers the following topics:
|
Note - Be sure to follow Section 8.2, Static Electricity and Other Precautions for all procedures. |
Most FRUs are hot-swappable. Hot-swappable means that a live upgrade can be performed - the FRU can be removed and replaced while the RAID array is powered on and operational.
|
Caution - Follow the FRU procedures carefully to ensure successful FRU replacement. |
Check that you received all field-replaceable units (FRUs) ordered with your Sun StorEdge 3120 SCSI array. For additional FRUs, consult your sales representative. For instructions on how to install or replace FRUs, review the following procedures or the Sun StorEdge 3000 Family Rack Installation Guide for 1U Arrays located on the product web site.
For a list of the FRU part numbers, refer to the Sun StorEdge 3000 Family FRU Installation Guide.
Follow these steps to prevent damaging the FRUs:
|
Caution - To prevent any possibility of data loss, back up the data prior to removing disk drives. |
Almost all FRU procedures are hot-swappable except for the chassis replacement procedure. However, you might need to power off the array (both power supplies) if you relocate the array or perform certain maintenance procedures with its associated servers.
Before you power off both power supplies, you must perform the following steps.
1. Stop all I/O activity to the array.
2. Power off both power supply/fan modules.
|
Note - For details on powering on the array, see Section 4.7, Power-On Sequence. |
This section provides instructions for removing and installing disk drive and air management sled FRUs, and covers the following topics:
To replace a disk drive, you first remove the defective disk drive and then install a replacement drive. The drive module is hot-swappable; it is replaced while the array is powered on.
Before replacing a disk drive, perform the following steps to ensure that you have identified the correct defective disk for removal.
|
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. For details, see Section 6.2, Front-Panel LEDs.
3. Record the Chl and ID number for the defective disk drive (for example, Chl 0 ID 4).
For descriptions of ID settings, see Section 4.6.2, Fixed Drive IDs.
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 Section 5.2, 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.
For details on the show enclosure-status command, see Section 5.4, Monitoring with the Sun StorEdge CLI.
|
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. An amber drive LED indicates a drive failure. For details, see Section 6.2, Front-Panel LEDs. |
|
Caution - To prevent any possibility of data loss, back up the data prior to removing disk drives. |
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.
