About degraded mode
When a RAID array experiences the failure of one disk, it enters in degraded mode. Content storage and
playback remains available on the ICMP.
CAUTION:
The loss of one disk causes no serious consequences on the ICMP. But action must be
taken quickly because the loss of a second disk will make the RAID system broken. The main cause
of the total loss of RAID is due in most cases to the loss of the second disk while the first has not
been rebuilt!
A failed drive should be replaced as soon as possible.
About
“
RAID recovery
”
process
The restoration from degraded to normal condition of the RAID 5 system is done automatically. When the
RAID controller detects a new HDD to replace the failed disk the recovery procedure starts automatically.
CAUTION:
The automatic process does not work if more than one disk is lost. In that case the RAID
must be completely initialized again!
About RAID broken
When more than one HDD is out of order, the RAID is considered as 'broken' and the content is lost. The failed
HDDs must be changed and a new RAID must be created.
Exchange or re-use of a disk set
It's possible to have several sets of disks with one ICMP or to reuse a complete set of disks coming from
another projector with ICMP. It is sufficient to insert the three HDDs, from a valid RAID array, and let the
system explore the new RAID. The mounting order of the HDDs and the HDD slots do not matter. Of course,
when using HDDs from another ICMP it is necessary to retrieve from the content distributor the KDMs
corresponding to the content and the new ICMP.
HDD storage capacity
Make sure that all HDDs in the ICMP HDD set have the same storage capacity. See label on top of the HDD to
know the storage capacity.
HDD storage
The maximum recommended storage period for the drive in a non-operational environment is 90 days. Drives
should be stored in the original unopened shipping packaging whenever possible. Once the drive is removed
from the original packaging the recommended maximum period between drive operation cycles is 30 days.
During any storage period the drive non-operational temperature, humidity, wet bulb, atmospheric conditions,
shock, vibration, magnetic and electrical field specifications should be followed.
HDD models validated by Barco
Only the original HDD spare parts provided by Barco or models validated by Barco (see list below) can be
used in the ICMP. All deviations from this rule void warranty.
List of validated models:
•
1TB: HGST

Western Digital (order code: HCC541010A9E630)
•
2TB: Seagate (order code : ST2000NX0253)
