Data Integrity
7-5
 A member of another logical drive fails.
 The subsystem has no spare left. Performance decreases for a
considerable portion of system resources has to be conducted
to generate data from the remaining members of the logical
drive. If yet another member fails in the logical drive, data is
lost.
The chance of failing two drives increases when a failed drive in the
array cannot be replaced immediately for the lack of spare drives.
The Function:
If a drive has a capacity smaller or apparently larger than the
members of configured arrays, the controller may avoid using it as a
global spare.
Enable the function and reset the controller for the configuration to
take effect.
7.2. Scheduled Maintenance
7.2.1 Task Scheduler
The Task Scheduler functionality allows Media Scans to be
scheduled beginning at a specified start time and repeating at
regular intervals defined by a configurable interval period. Each
such schedule can be defined to operate on individual drives, all
drives of a certain class, all member drives of a specified logical
drive, or all member drives of all logical drives. UIs supported are
RS232C terminal menus and RAIDWatch GUI manager.
