Replacing a Failed Drive and Using
Spares
The TaskSmart N2400 appliance is designed with many fault-tolerant features
to prevent common problems. However, if a drive fails, it must be replaced.
Because your external drives are set up in RAID 5 arrays with distributed data
guarding, the loss of a single drive in an array does not result in any loss of
data. However, you must replace the failed drive as soon as possible. Until a
failed drive is replaced, your TaskSmart N2400 appliance is operating in a
non-fault-tolerant mode. If another drive is lost before the failed one is
replaced and rebuilt, you can lose all data on the array.
NOTE: Refer to the maintenance and service guide for detailed procedures about
hardware failures on the TaskSmart N2400 appliance.
Failed drives can be replaced without the server being powered down. The
drives in your server are hot-pluggable. To identify failed drives, look for one
or more of the following:
An amber LED is illuminated on a failed drive. This LED indicates that
the storage enclosure is powered up and that the SCSI cable connecting
the storage enclosure to the server is working.
NOTE: The amber light may briefly illuminate when the drives are inserted. This
illumination is normal and does not indicate a failure condition unless the LED remains
illuminated.
An amber LED is illuminated on the storage enclosure. This LED
indicates that one or more drives in the storage enclosure has failed, a
fan failure has occurred, or a high-temperature condition exists.
A (POST) message lists failed drives when the TaskSmart N2400
appliance is restarted. This message is dependent on the array controller
detecting one or more "good" drives.
The Array Diagnostics Utility (ADU), found on the SmartStart and
Support Software CD, reports failed drives.
The Compaq Insight Manager reports failed drives or prefailure
conditions on one or more drives.
