Determine if the PDB Is Faulty

Language:

You must determine if the PDB is faulty before you replace it.

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

In Oracle ILOM, check the health of the power system.
```
-> show /System/Power 
 /System/Power
 	Targets:
 	Properties:
 		health = OK
 		health_details = -
...
->
```
If the health_details property identifies a faulty PDB, replace it. See Remove the PDB.

Verify that the PDB is faulty.
If the PDB is faulty, you will see /SYS/PDB under the Value heading.

For example:
```
-> show faulty
Target              | Property               | Value
--------------------+------------------------+-------------------------------
/SP/faultmgmt/0     | fru                    | /SYS/PDB
...
->
```
If the PDB is faulty, replace it. See Remove the PDB.

If a FRU value different from /SYS/PDB 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 the PDB is faulty, replace it. See Remove the PDB.

Within the Oracle ILOM interface, verify that the PDB is reporting temperatures.
```
-> show /SYS/PDB/T_IN_PSx value
 /SYS/PDB/T_IN_PS
 	Properties:
 		value = 26.000 degree C
->
```
If an unreasonable temperature or no temperature is displayed, replace the PDB. See Remove the PDB.

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