Planning: MD3200 Series Storage Array Terms and Concepts

If a disk drive rebuild fails because of a source drive failure or because the 

drive is too small, the MDSM reports a failure of the physical disk even 

though the LED state on the drive indicates the rebuild was aborted (green 

for 3 seconds, amber for 3 seconds, then off for 3 seconds).

SMART monitors the internal performance of all physical disk components to 

detect faults indicating the potential for physical disk failure. SMART uses 

this information to report whether failure is imminent so that a physical disk 

can be replaced before failure occurs. The storage array monitors all attached 

drives and notifies you when a predicted failure is reported by a physical disk. 

When configuring a storage array, you must:

1 Organize the physical disks into disk groups. 
2 Create virtual disks within these disk groups.
