• Number of Logical Drives – The number of logical drives that belong to this
disk array.
• Supported RAID Level – The RAID level of this disk array.
• Physical Drives in the Disk Array
•
Slot No. – This is the slot number of a physical drive that belongs to this
disk array.
• Model – The physical drive's model name from the manufacturer.
• Type – Serial ATA (SATA) or Parallel ATA (PATA).
• Configurable Capacity – This is the available data storage capacity of
this physical drive.
• Status – This refers to functional status of this physical drive.
•
Functional means normal.
• Disk is being rebuilt means this drive is the Target Drive of the
rebuild operation that is in progress.
• Disk Offline means this drive is not available for use due to an error.
See Rebuild Disk Array.
• Logical Drives in the Disk Array
•
Device ID – This is the ID number of a logical drive that belongs to this
disk array.
• Alias – A user-specified name for this logical drive.
• RAID Level – This is the RAID level of this logical drive.
• Capacity – This is the available data storage capacity of this physical
drive.
• Status – Functional, Synchronizing, Rebuilding, Critical, or Offline (see
definitions below).
Disk Array and Logical Drive Status Definitions
• Functional – This is the normal state of a logical drive. When a logical drive
is Functional, it is ready for immediate use. For RAID Levels other than RAID
0 (Striping), the logical drive has full redundancy.
• Synchronizing – This condition is temporary. Synchronizing is a
maintenance function that verifies the integrity of data and redundancy in the
logical drive. When an logical drive is Synchronizing, it will function and your
data is available. However, access will be slower due to the synchronizing
operation.
• Rebuilding – This condition is temporary. When a physical drive has been
replaced, the logical drive automatically begins rebuilding in order to restore
redundancy (fault tolerance). When a logical drive is rebuilding, it will
function and your data is available. However, access will be slower due to
the rebuilding operation.
