Status: (Functional, Critical, Offline)
Functional: Means the array is providing full functionality.
Critical: Used only in reference to a Mirroring array (RAID 1 or RAID 0+1). A
problem has been detected in one of the drives in 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
recommend 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 or Spanning array.
“Offline” results from a drive having failed and 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 in an array in the left pane, the right pane will show the
information of that drive.
Status (also shown under the Array Window) can be Functional, Critical, or Offline.
Functional: Means the drive is working normally.
Critical: A problem has been detected on the drive and the drive has been taken
offline. 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 or Spanning array contains a “bad” drive. These drives do NOT
need to be replaced, however.
S.M.A.R.T. Status: Indicates whether the attached hard drive implements Self-
Monitoring Analysis & Reporting Technology to predict drive failure.
Size: Indicates capacity of individual drive.
