The Array Drive Information Window
Double click on the array drive icon. This window shows information on an array drive (for
example, a disk array). See Figure 86.
Figure 86. Array Drive Information Window
Drive No The logical number of the array drive.
Drive Name The name of the array drive.
Type RAID level of the array drive. Possible levels are RAID 0 (data striping, no
redundancy), RAID1 (mirroring), RAID 4 (striping with parity drive), RAID 5
(striping with striped parity) or RAID 10 (combination of RAID 1 and RAID 0).
Status The status of an array can be ready (operational), fail (one drive missing, still
operational but not redundant), error (more than one drive failed, not
operational), rebuild (one drive is being integrated), build (initial preparation of
the array), idle (new defined array, before build process has started), or expand
(one or several drives are added online to the array drive).
Capacity This is the capacity available for the corresponding host drives.
Attributes The attribute of an array drive is usually read/write ([RW]). If a component of a
disk array is missing during startup and the operator decides not to activate fail
mode, the array is set to the read only attribute ([RO]). When the missing drive
becomes available, the array drive shows the ready status (for example,
attribute [RW]).
Striping Size (RAID 0, 5, 10) Data written on RAID 0, 4, 5, or 10 drives is distributed over all
drives (striping). The striping size can only be changed at the time the drive is
created (standard setting is 32KB).
