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 EVS server 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 definitively lost.
Warning
By default, the online rebuild process takes up 10% of the disk bandwidth. If you
want to change this, contact EVS support.
2.5.4. Clearing Video Disks
Introduction
This function is used to delete media from the RAID disk array. This will permanently
delete the video and audio data, including protected clip and record trains.
When you change the multi-essence configuration, you may also have to clear Intra,
LongGOP clips, or all clips. The decision depends on the initial and the new multi-essence
configuration. The table in this section will help you make the decision.
Three options are therefore possible:
• Clearing the media on all video disks (full clear clip)
• Clearing only the Intra clips (partial clear clip)
• Clearing only the LongGOP clips (partial clear clip)
Required and Optional Clear Clips
When Required is specified in the following table, a full clear clip is required when you
shift from the given source configuration to the given target configuration.
When Optional is specified in the following table, a partial clear clip is useful, but is not
required. It allows you to remove old material you will no longer want to or be able to use,
while keeping material corresponding to the still active essences.
