Function: „Manager“
In this function you can manage RAID array
Available operations:
RAID 0:
Construction of this RAID does not allowed to manage it anyway. Every unit must
not be Failed. If any would be the whole array would be destroyed.
RAID 1:
• To set unit as a Faulty one mark proper checkbox (in the column F) and click on
Apply button.
• To delete any unit form an array mark proper checkbox (in the column R) and
click on Remove button.
RAID 5:
• To set unit as a Faulty one mark proper checkbox (in the column F) and click on
Apply button.
• To delete any unit form an array mark proper checkbox (in the column R) and
click on Remove button.
RAID 6:
• To set unit as a Faulty one mark proper checkbox (in the column F) and click on
Apply button.
• To delete any unit form an array mark proper checkbox (in the column R) and
click on Remove button.
RAIDs notation:
• PR - priority in array - describes priority of unit that will be added to array if
another is set to Faulty.
• F - faulty - unit can be turned off from array
• R - hot remove - unit can be removed form array without shutting down the
system.
• ST - describes state of unit in array, which can be:
o A - This means that Unit is active in array
o * - Number of Unit that belongs to the array
o S - Spare or spare rebuilding - this means that unit is free and can be
added to the array or is free and currently is rebuilding.
Limitations:
• There is no possibility to set any unit as faulty if the matrix is degraded or during
resync/rebuild.
• While using RAID 1 and RAID 5 there is possibility to set only one disk from
active as faulty. This regulation is not valid for Spare units in array.
Only one disk form Active in Array can be set as Faulty or Removed
