A Logical Drive can be either a singledisk, or a chaining group of disks (concatenation), or a stripe set of several disks.Drive No The number of the Logical Drive.Drive Name The name of the Logical Drive.Type The type of the Logical Drive. A Logical Drive can be either a singledisk, or a chaining group of disks (concatenation), or a stripe set ofseveral disks.Status This is the state of the Logical Drive. It can be ready, missing (notavailable after reset) or failed (i.e., no longer available for the con-troller).Capacity The capacity which is available for Array Drives or Host Drives.Attributes The attribute of a Logical Drive is usually read/write ([RW]).If a component of a disk array is missing while startup and the op-erator decides not to activate fail mode, the array is set to the readonly attribute ([RO]). When the missing drive is available again, theArray Drive shows again the ready status (i.e., attribute [RW]).Last Status The last status information of a Logical Drive. This is different tothe last status information of Physical Drives.RAID 1 Com-ponentIf the Logical Drive is a member of a RAID 1 array, it can be eithermaster or slave. If a RAID 1 component is added to a Logical Drive,the data is read from the master and written to the added LogicalDrive (the slave). One master may have several slaves.RAID 4/5 Com-ponentAs a member of a RAID 4 or RAID 5 array a Logical Drive can be themaster or a component. Different to RAID 1 arrays, this is only im-portant for the internal structure of the array.
