I have got a Raid Array which had 2x hdds fail and 1x controller fail. Secondery controller has taken over... and is now the primary. drives have been replaced and rebuilt but controller still needs to be replaced.... another drive failed again but different possition. Has been replaced and rebuild has been done. But now raid has frozen and the RAID is sounding an audible error message prior to this which was consisted of a short beep every 4 or 5 seconds.This has now changed to 3 beeps which are about 1 second apart , there is then a short pause and this then repeats.' I think this is to do with the voltage but would like to know what people think and what could be causing all these problems... primary controller i solid green but should be flashing... any solutions to this problem would be appreciated.
