|  |           |       |    * "Device Absent" indicates that the fan is either|
|  |           |       |    not inserted correctly or the power supply cable  |
|3 |Fan        |Failed |    for the fan is loose.                             |

|  |           |       |    supply cable is inserted correctly on the         |
|  |           |       |    motherboard, call Veritas support to replace the  |
|  |           |       |    fan.                                              |

|  |           |       |    * Speed will be above the high water mark levels. |
|  |           |       |    Check if any other fan is in failed state. If yes,|
|  |           |       |    call Veritas support to replace the failed fan.   |
|4 |Fan        |Warning|    Once replaced, the speed will stay within water   |
|  |           |       |    mark level.                                       |

|  |           |       |    temperature table. If the temperature of appliance|
|  |           |       |    rises, then fan speed increases unless proper     |
|  |           |       |    cooling is provided to the machine.               |

|  |           |       |    copyback needs to be initiated so that the drive  |
|  |           |       |    in this particular slot becomes a "hotspare"      |
