3 SPARC HARD DISK BACKUP

Like any other FIERA Controller part, a spare Hard Disk must exist for the FIERA SPARC of each Instrument for the replacement in case of failure.

The spare Hard Disk must contain an exact copy of the contents of the SPARC Hard Disk installed on an Instrument: for this reason the Spare Hard Disk must be updated every time the Instrument SPARC Hard Disk contents are modified (e.g., a VLT Software upgrade).

The backup Hard Disk can be prepared using ufsdump on the the second hard disk of the SPARC (see 2.1.2 for reference).
