XT2 Series DISK RECORDER – Version 10.05 - Software Technical Reference

EVS Broadcast Equipment SA – Jluly 2011

When a disk is disconnected, it is orange and the RAID status section displays the

percentage rebuilt at the position of the RAID number. When a disk is

disconnected but new media is still being recorded on the disk array, this number

will decrease until the disk is replaced and the rebuild process starts. The rebuild

is complete when this number reaches 100%.

REBUILD PROCESS

The XT2+ server is capable of performing a rebuild process of the RAID. This

process can happen either while the Multicam application is not running (offline

process – rebuild is faster) or while the Multicam application is running (online

process – rebuild is slower).

Disconnection process

As explained in the previous section, the software will disconnect a disk that does

not behave as expected.

Two options are available for the operator:

• Replace the disconnected disk and restart the server

o Start the Multicam application. The rebuild process will start automatically.

o Start a hardware check from the EVS menu and launch the rebuild. The

process starts offline. The operator can wait for the rebuild to be

completed or cancel it (that is to say postpone it) and start the Multicam

application, in which case the rebuild carries on in online mode.

• The operator can also force the disk to be reconnected by starting the rebuild

process in the hardware check. The process starts offline. The operator can

wait for the rebuild to be completed or cancel it and start the Multicam

application, in which case the rebuild carries on in online mode.

Note:

If errors are detected during the rebuild process, a message appears

after the rebuild is complete to warn the operator, and the raid is not

considered as properly rebuilt. In this state, the system will keep working

on 4 disks (4+1 configuration) or on 5 disks (5+1 configuration). If you

want to run on 5, or 6, disks again, you can try replacing the disk again

and perform another rebuild, or clear all clips.

If you don’t need to retrieve the clips or the record trains, you don’t need to

rebuild the RAID. In this case, select the “Clear All Clips” answer when the

message with this option appears in the Hardware Check.

If you don’t rebuild the RAID array or if you don’t clear clips, the XT2+ will keep

running on 4, or 5, disks only, and you will see a warning message appearing

every time you start or close the Multicam application. Normal operation can be

achieved on 4, or 5, disks, but then, if another disk fails, the system will hang and

all video and audio data will be definitely lost.
