Diskarraysaremadeupofphysicaldrives.Logicaldrivesarecreatedonthediskarray.
When one of the physical drives in a disk array fails:
• The operational status of the disk arraybecomesCritical.
• The operational status of the logical drivesbecomesCriticalorDegraded.
• The operational status of the physical drive becomes Dead or Ofine.
ASUS Storage Management reports these conditions in the following places:
