5.1.2 Identifying a Broken Hard Disk
In case of an alarm or when suspecting a worn hard disk, you have to
identify the broken hard disk first in order to replace it.
In most cases you can find the broken disk by simply observing the
LEDs of the disk array (see section “Hard Disk Array” on page 2-7 and
section “System Disk Array” on page 2-12). While performing continu-
ous accesses to the data, it will be the one:

no longer blinking (either continuously on or off),

irregularly blinking compared to the other hard disks of the same
disk set, or

showing a hard disk or disk carrier related error (see section “Hard
Disk Array” on page 2-7 and section “System Disk Array” on
page 2-12).
Once the broken disk has been identified, you can replace it as de-
scribed in section “Replacing a Hard Disk” on page 5-5.
An alarm can be caused by a number of reasons. Please refer to section
“Troubleshooting” on page A-2 first for further details about what to do
in case of an alarm.
If a hard disk fails, the alarm will be sounded by a RAID controller. It can-
not be switched mute with the mute button of the operation items. It
can be turned off either with the RAID software manager or by replacing
the broken hard disk.
Data accesses to the hard disk array are still possible because any miss-
ing data will be recalculated from the parity information stored on the
other hard disk(s). This can limit the overall performance and real-time
operations may no longer be possible.
Data loss
If you do not replace a broken disk in time and another disk fails in
the meantime, your data may be unrecoverable.
Replace a broken hard disk as soon as possible.
Before replacing a hard disk you have to gather the log files of the RAID
controller. If you know how to do this you may proceed on your own. If
not, please contact the R&S DVS service department first.
Data loss
Replacing the wrong hard disk, i.e. a good one instead of the bro-
ken one, may result in a total loss of data.
If you are unsure about having detected the correct hard
disk please contact the R&S DVS service department.
