Function: Manager
Using this function you can manage the RAID array.
Available operations:
RAID 0:
The design of this RAID does not permit management of it. No units can have failed status. If any of them fail, the whole array will be disabled.
RAID 1:
* To mark a unit as Faulty, check the appropriate option (in the F column) and click Apply.
* To delete any unit from an array, check the appropriate option (in the R column) and click Remove.
RAID 5:
* To mark a unit as Faulty, check the appropriate option (in the F column) and click Apply.
* To delete any unit from an array, check the appropriate option (in the R column) and click Remove.
RAID 6:
* To mark a unit as Faulty, check the appropriate option (in the F column) and click Apply.
* To delete any unit from an array, check the appropriate option (in the R column) and click Remove.
RAID notation:
* PR - priority in array This represents the priority of a spare unit which will be added to the array if another unit is marked as Faulty. The higher the priority, the sooner this unit will be used.
* F - faulty The unit can be removed from the array.
* R - hot remove This unit can be removed from the array without shutting down the system.
* ST - characterizes the state of a unit in the array, which can be:
* A - active
* * - unit number within the array
* S - spare or spare rebuilding This means that the unit is free and can be added to an array, or is free and is currently rebuilding.
Limitations:
* It is not possible to set any unit as Faulty, if the matrix is degraded or during resync/rebuild.
* When using RAID 1 and RAID 5, it is possible to mark only one disk from among the active disks as faulty. This regulation is not valid for spare units in an array.
Note
Only one disk from within the active group in an array can be marked as Faulty or Removed.
