1. ICMP HDD replacement kit
A failed drive should be replaced as soon as possible.
C
AUTION
:
A RAID 5 con
fi
guration with three HDDs allows a maximum loss of one disk.
With the simultaneous loss of more than one HDDs, data is lost and the RAID must be
completely initialized again!
About degraded mode
When a RAID array experiences the failure of one disk, it enters in degraded mode. Content storage and
playback is always available on the ICMP.
C
AUTION
:
The loss of one disk causes no serious consequences on the ICMP. But ac-
tion must be taken quickly because the loss of a second disk will make the RAID system
inoperative. The main cause of the total loss of RAID is due in most cases to the loss of
the second disk while the
fi
rst has not been rebuilt!
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.
C
AUTION
:
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 destruction
When more than one HDD is out of order, the RAID is considered as destroyed 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 reuse a set of disks coming from another projector with ICMP. It is suf
fi
cient to insert 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, it’s necessary to retrieve the KDMs corresponding to content
and the ICMP from the content distributor.
