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 2-6 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 2-6 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 de-
tails about what to do in case of an alarm.
If a hard disk fails, the alarm will be sounded by a RAID con-
troller. It cannot be switched mute with the mute button of the
operation items. It can be turned off either with the RAID soft-
ware manager or by replacing the broken hard disk.
Data accesses to the hard disk array are still possible because
any missing data will be recalculated from the parity informa-
tion stored on the other hard disk(s). This can limit the overall
performance and real-time operations may no longer be possi-
ble.
Replace the failed disk as soon as possible. If you do not re-
place a broken disk in time and another disk fails in the mean-
time, your data may be unrecoverable.
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 pro-
ceed on your own. If not, please contact the DVS service de-
partment first.
Replacing the wrong hard disk, i.e. a good one instead of the
broken one, may result in a total loss of data.
If you are unsure about having detected the correct hard disk
please contact the DVS service department.
