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 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). Promise
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 or Spanning
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.
