MV 4105_Ciprico Inc.
Audible Alarm
The MV 4105 sounds an alarm when there is a problem with a drive.
Corrective actions should be applied to fix the problem.
TABLE 5-7. Audible Alarm Beeps and Tone.
3 Short and 3 Long Beeps
These beeps is normally associated with a Fibre Channel interface
problem.
Always turn on the MV 4105 first, then turn on the computer. You might
need to physically reseat the Fibre Channel connections or the SFP
module, or replace these components.
Slow Beeps
One or more slower beeps indicate a bad drive or an intermittent drive; the
number of beeps indicates which drive is having problems.
When operating in RAID 3 mode the MV 4105 is still available for normal
operation without performance degradation, but the beeps indicate that a
drive is down and the MV 4105 is running in a degraded RAID 3 state. If
another drive fails data might be lost.
To service the unit, any data that needs to be kept must be off loaded to
another fully functional unit. Send the entire defective unit to the service
center. The defective component will be replaced or repaired and returned
to the sender. Data will not be preserved by the service center. Upon
receiving the repaired unit, reformat and partition the MV 4105. Restore
any needed data.
Constant, Solid Tone
This indicates that a drive is down. The Service indicator should also be
on.
One of the drive indicators should exhibit a slow blink (one second on, one
second off). The drive needs to be serviced. See the “Drive Replacement”
section in Chapter 8, Maintenance, for more information.
Mute the alarm by pressing the Mode Set button once. Holding the Mode
Set button until two beeps are heard starts the rebuild process. (This is
typically done only after a replacement drive module had been installed to
replace a defective drive module).
