2.3.6 SINGLE DRIVE / SEGMENT
The single drive is a virtual disk that can either be an entire disk drive or a segment of a single
disk drive. Single drive is the “Contiguous” configuration option when creating RAID Groups
(or sets) in the SATARAID5 software.
2.4 RAID VOLUME STATUS
A RAID volume can be in any one of the following statuses.
STATUS MEANING
Good All disks are currently functioning as normal.
Reduced
For RAID levels that provide data protection, one or more disks have
failed but the data is still available via the RAID algorithms. The failed
disk should be replaced as soon as possible to avoid loss of data.
Rebuilding
A failed disk drive has been replaced and the data is being regenerated
on the replacement disk. When complete, the RAID Group will return to
Good status.
Resynchronizing
An error has occurred and RAID algorithms be regenerated on this
RAID Group. When complete, the RAID Group will return to Good
status.
Failed
One or more disks have failed and RAID algorithms can no longer
regenerate the data. The minimum number of failures required to reach
this state depends on the RAID level:
z RAID 0, Concatenated, Contiguous: Single disk failure.
z RAID 1, 10, and 5: Two disk failure.
