The Logical Drive Information Window - ICP RS Series User Manual

K.5.3 The Logical Drive Information Window
Double click on the Logical Drive icon.
This window shows information on a Logical Drive. A Logical Drive can be either a single
disk, 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 single
disk, or a chaining group of disks (concatenation), or a stripe set of
several disks.
Status This is the state of the Logical Drive. It can be ready, missing (not
available 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 read
only attribute ([RO]). When the missing drive is available again, the
Array Drive shows again the ready status (i.e., attribute [RW]).
Last Status The last status information of a Logical Drive. This is different to
the last status information of Physical Drives.
RAID 1 Com- If the Logical Drive is a member of a RAID 1 array, it can be either
ponent master 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 Logical
Drive (the slave). One master may have several slaves.
RAID 4/5 As a member of a RAID 4 or RAID 5 array a Logical Drive can be the
Component master or a component. Different to RAID 1 arrays, this is only im-
portant for the internal structure of the array.
