◦ Expanding - The logical drive is currently doing Automatic Data Expansion. During
Automatic Data Expansion, fault tolerance algorithms redistribute logical drive data to
the newly added physical drive.
◦ Not available - The logical drive is currently unavailable. If a logical drive is expanding
and the new configuration frees additional disk space, this free space can be configured
into another logical volume. If this is done, the new volume will be set to Not Available.
◦ Queued for expansion - The logical drive is ready for Automatic Data Expansion. The
logical drive is in the queue for expansion.
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.
When the status is Expanding the following will be displayed to indicate the progress of the
operation.
• Percent Expand Complete displays the percent complete of the expansion. When a logical
volume is expanding, the drive must redistribute the logical volume data across the physical
drives. When the value reaches 100, the expansion process is complete.
• Fault Tolerance displays the fault tolerance mode of the logical drive. To change the fault
tolerance mode, run the System Configuration Utility.
The following values are valid for the Logical Drive Fault Tolerance:
◦ None - Fault tolerance is not enabled (referred to as RAID 0). If a physical drive reports
an error, the data cannot be recovered by the drive array controller.
◦ Mirroring - For each physical drive, there is a second physical drive containing identical
data (also known as RAID 1). If a drive fails, the data can be retrieved from the mirrored
drive.
◦ Data Guarding - One of the physical drives is used as a data guard drive and contains
the exclusive OR of the data on the remaining drives (also known as RAID 4). If a failure
is detected, the drive array controller rebuilds the data using the data guard information
plus information from the other drives.
◦ Distributed Data Guarding - Distributed data guarding (sometimes referred to as RAID 5)
is similar to data guarding, but instead of storing the parity information on one drive, the
information is distributed across all of the drives. If a failure is detected, the Drive Array
Controller rebuilds the data using the data guard information from all the drives.
◦ Advanced Data Guarding - (RAID ADG) is the fault tolerance method that provides the
highest level of data protection. It stripes data and parity across all the physical drives
in the configuration to ensure the uninterrupted availability of uncorrupted data. This
fault-tolerance method is similar to RAID 5 in that parity data is distributed across all
drives in the array, except in RAID ADG the capacity of multiple drives is used to store
parity data. Assuming the capacity of 2 drives is used for parity data, this allows continued
operation despite simultaneous failure of any 2 drives in the array, whereas RAID 4 and
RAID 5 can only sustain failure of a single drive.
◦ Unknown - You may need to upgrade your software.
• Capacity displays the size of the logical drive.
