Locate a Faulty Drive

Language:

You must determine which drive is faulty before you replace it.

Check to see if any System Service Required LEDs are lit or flashing.
See Interpreting Diagnostic LEDs.

Visually inspect the installed drives to see if any of their status LEDs are lit or flashing.
See SAS Drive LEDs.

If a drive is faulty, replace it. See Remove a SAS Drive.

In Oracle ILOM, check the health of the storage system.
```
-> show /System/Storage
 /System/Power
 	Targets:
 		Disks
 		Controllers
 		Volumes
 		Expanders
 	Properties:
 		health = OK
 		health_details = -
...
->
```
If the health_details property identifies a faulty drive, replace it. See Remove a SAS Drive.

Check the health of the individual drives.
```
-> show /System/Storage/Disks/Disk_x 
 /System/Storage/Disks/Disk_0
 	Targets:
 	Properties:
 		health = OK
 		health_details = -
...
->
```
where x is the number of the drive, from 0 to 7.

If the health_details property identifies the drive as faulty, replace it. See Remove a SAS Drive.

Verify that a drive is faulty.
If a drive is faulty, you will see /SYS/DBP/HDDx under the Value heading, where x is 0 to 7.

For example:
```
-> show faulty
Target              | Property               | Value
--------------------+------------------------+-------------------------------
/SP/faultmgmt/0     | fru                    | /SYS/DBP/HDD0 
...
->
```
If a drive is faulty, replace it. See Remove a SAS Drive.

If a FRU value different from /SYS/DBP/HDDx is displayed, see Component Service Task Reference to identify which component is faulty.

Use the Oracle ILOM faultmgmt shell to identify the faulty component.
See Display Faults (faultmgmt Shell).

Check the Fault class and Description fields for more information.

If a drive is faulty, replace it. See Remove a SAS Drive.

If you are unable to determine if a drive is faulty, seek further information.
See Detecting and Managing Faults.
