• Number of Logical Drives – The number of logical drives that belong to this

disk array.

• Supported RAID Level – The RAID levels this disk array can support.

Physical Drives in the Disk Array

• Slot No. – Physical drive ID number.

• Model – The physical drive's model name from the manufacturer.

• Type – SATA or PATA.

• Configurable Capacity – This is the available data storage capacity of this

physical drive.

• Status – OK is normal. Can also show Rebuilding, Forced Online, Forced

Offline, Transition Running, PDM Running, Media Patrol Running, Stale,

PFA, Offline or Dead (see definitions below).

Logical Drives in the Disk Array

• Device ID – This is the ID number of a logical drive that belongs to this disk

array.

• Alias – Optional.

• 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

below).

Disk Array Status

• Functional/OK – This is the normal state of a logical drive. When a logical

drive is Functional, it is ready for immediate use. For RAID Level s other than

RAID 0 (Striping), the logical drive has full redundancy.

• Synchronizing – This condition is temporary . Synch ronizing is a maintenanc e

function that verifies the integrity of data and redundancy in the logica l drive.

When a logical drive is Synchronizing, it will function and your data is

available. However, access will be slower due to the synchronizing

operation.

• Critical/Degraded – This condition arises as the result of a physical drive

failure. A degraded logical drive will still function and your data is still

available. However, the logical drive has lost redundancy (fault tolerance).

You must determine the cause of the problem and correct it.

• 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.
