Hard Disk Maintenance
The following figure shows a representation of the hard disk array of the
R&S DVS system (see also section “Hard Disk Array” on page 2-9). It
indicates the location of the disk sets (RAID packs) in the hard disk ar-
ray:

With the available RAID feature the R&S DVS system can withstand
disk failures without losing data or access to data.
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.
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 realtime
operations may no longer be possible.
Not replacing broken hard disk
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.
