Offline—The logical drive is offline and cannot be accessed by the operating system.
User action may be required to bring the drive back online.
Unknown—The Storage Agents cannot determine the status of this drive. You may need
to upgrade your driver software or Storage Agents.
Raid Level—Displays the raid configuration of the logical drive. The possible values are:
RAID 0–Fault tolerance is not enabled. If a physical drive reports an error, the data cannot
be recovered.
RAID 1 Mirroring is the highest level of fault tolerance. It is the only method offering fault
tolerance protection if no more than two physical drives are selected. Drive mirroring
creates fault tolerance by storing duplicate data on two drives. There must be an even
number of drives. This is the most costly fault tolerance method because it requires 50
percent of the drive capacity to store the redundant data.
Unknown—The Storage Agents cannot determine the raid configuration of this logical
drive. You may need to upgrade your driver software or Storage Agents.
Capacity—Displays the size of the logical drive. A megabyte (MB) is 1,048,576 bytes, a
gigabyte (GB) is 1,073,741,824 bytes, and a terabyte (TB) is a thousand gigabytes.
Drive manufacturers sometimes use the number 1,000,000 as a megabyte when giving drive
capacities so this value may differ from the advertised size of a drive.
Stripe Size—The size of a logical drive stripe or group of data written to a physical drive in
kilobytes. It may be zero in some raid configurations.
OS Assigned Name—Displays the operating system name associated with this logical drive.
When the status is Rebuilding the following will be displayed to indicate the progress of the
operation.
Percent Rebuild Complete—Displays the percent complete of the rebuild. When the value
reaches 100, the rebuilding process is complete. The drive array continues to operate in
interim recovery mode while the drive is rebuilding.
Rebuilding—Drive identifies the physical drive that failed. The logical drive is rebuilding
using a spare drive in place of this failed drive.
