Symptoms

Exadata alerts are generated when a flash disk fails.  The alerts include specific instructions for replacing the flash disk. 

If you have configured the system for alert notifications, alerts will be send by email to the
designated address. Example of the automatic alert is displayed below:

Hardware Alert 87 is triggered at 2010-05-07T09:18:42-04:00 with message:

[10:0:3:0]. Slot Num: PCI Slot: 1; FDOM: 3. Serial Number: 5080020000932b0FMOD3.
Celldisk: FD_03_dmorlcel06.
No Griddisks exist on this lun.
CELL name: dmorlcel06, System serial number: 1004XFG002
The suggested action is: Refer to section Maintaining Physical Disks in the
Exadata User Guide.

1. Manually replace physical disk [10:0:3:0] Slot Num: PCI Slot: 1; FDOM: 3.

After the physical disk is replaced, if required, the Griddisks will be
automatically created and ASM will automatically perform data redistribution as
per the default rebalance power level (asm_power_limit parameter).
