Array

One of the hard disk which has been part of a working array in EXP300 storage unti and has not clustered yet has had its light turn steady green. It is not defunt as no message relating to this has come up. We moved the HDD aroung the storage unit, rebooted the unit and even chaged the SCSI ID around but still the light reamin steady green.

Please what could be wrong and how can we rectifiy this.

Thanks for your prompt help
