Thus, a DVS system equipped with RAID 5 can withstand disk failures
without losing data or access to data.
5.1.2 Replacing a Hard Disk
In case of a hard disk failure an alarm will be sounded. Then during con-
tinuous accesses to the hard disk array you can identify the broken disk
easily: It will be the one no longer blinking (either continuously on or
off). With this you have the possibility at hand to replace the broken
disk.
The hardware replacement of a failed disk can be divided into three
steps:
1.
Remove the hard disk from the system.
2.
3.
Reassemble it into the system.
All steps are explained in the following.
If a second disk within the same disk set fails, your data will
be unrecoverable.
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 of the hard disk array fails, the alarm will be
sounded by a RAID controller. It cannot be switched mute with
the mute button of the operation items. It can be turned off ei-
ther with the RAID software manager or by replacing the bro-
ken hard disk.
Data accesses to the hard disk array are still possible because
any missing data will be recalculated from the parity informa-
tion distributed among the other hard disks of the disk set.
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.
