RAID Function
Status: (Functional, Critical, Offline)
Functional: Means the array is providing full functionality
Critical: Used only in reference to a Mirroring array (RAID 1). A problem has been
detected in one of the drives of the array and the drive has been taken "offline."
However, a "critical" array will continue to save and retrieve data from the remaining
working drive(s). We recommends replacing the failed drive as soon as possible since a
"Critical" array offers no data redundancy.
Offline: This would appear most commonly within a RAID 0 array. The "Offline"
results from a drive having failed which has taken the entire array "offline." In
this case, you have likely lost data. Fix/replace the drive that has failed, then
restore data from a backup source.
Viewing Arrayed Drive Information
By left-clicking on a drive member of an array in the left pane, the right pane shows the
following information categories for that drive:
Status (also shown under the Array Window) can be Functional, Critical, or Offline.
The meanings are shown below.
Functional: Means the drive is working normally
Critical: A problem has been detected in the drive and the drive taken offline as
part of a mirroring array. Mirrored arrays will continue to function without the
drive. Fix/replace the drive that has failed, then restore data from a backup source.
Offline: Drives that are NOT identified as "bad" may be taken offline if part of a
Striping array containing a "bad" drive. These drives do NOT need to be replaced,
however.
