– irregularly blinking compared to the other hard disks of the
same disk set, or
– showing a hard disk or disk carrier related error like a lit up red
alarm LED on a particular hard disk (see section “Hard Disk
Array” on page 2-7).
Once the broken disk has been identified, you can replace it as de-
scribed in section “Replacing a Hard Disk” on page 5-4.
5.1.3 Replacing a Hard Disk
As soon as the broken hard disk has been identified (see section “Iden-
tifying a Broken Hard Disk” on page 5-3), it can be replaced easily. The
replacement of a broken hard disk can be divided into three steps:
1. Removing the hard disk from the system.
2. Replacing the hard disk.
3. Reassembling it into the system.
All steps are explained in the following.
Step 1: Removing the Hard Disk
The hard disks that are accessible at the front of the system are con-
nected to the system with the help of disk carriers. They can be re-
moved easily, even when the system is running (hot-swappable).
To remove a hard disk from the system perform the following:
 If appropriate, stop all accesses to the hard disk array of your sys-
tem, for example, by exiting the video system software and sever-
ing the network connections.
 Fold down the faceplate of the system (see section “The Front of
the System” on page 2-4).
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.
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.
For an overview of a disk carrier as well as further information
about it see section “Hard Disk Array” on page 2-7.
