184Software Installation and User’s GuideICP RAID NavigatorFigure 11-145. Add RAID1 Component1. To add a RAID 1 component, select a logical drive, the master. All suitable logicaldrives (with a capacity equal to or larger than the capacity of the master) are shown ina box.2. Choose the logical drive you want to add, the slave. After confirming, a new RAID 1array drive is built, for example, all data from the master is copied to the slave drive(s).When this process is finished all logical drives in the RAID 1 array drive are identical(there is no longer a difference between master and slave).11.5.19 Remove RAID 1 Component (Remove a Mirror Drive)Click the right mouse button on the logical drive icon.Here you can remove a drive from a RAID 1 array drive. If the array drive is in the buildor fail state, you may only remove invalid RAID 1 components.To remove a logical drive from a RAID 1 array drive select the logical drive you want toremove. This is done by selecting a logical drive from a box where you see all members ofthe RAID 1 array drive. After confirmation the logical drive is removed. If the RAID 1array drive consists of two drives, the RAID 1 array drive disappears and only one logicaldrive is left. You can create a new RAID 1 array drive by selecting add RAID 1.11.5.20 Replace DriveClick the right mouse button on the logical drive icon.If a logical drive of an array drive without a hot fix drive should fail (or is very likely tofail), you should replace the defective hard disk with a new one as soon as possible,because the array drive is without redundancy. The replacement logical drive has to haveat least the same capacity as the failed one. The replacement is carried out with ICPCONor the ICP RAID Navigator. Before the logical drive can be removed, you must select anew logical drive from the box with available physical drives that is shown after thisoption is selected. If no physical drive is offered, you have to use the Hot Plug: ReplaceDrive function to add a new drive. After the confirmation, the old logical drive isremoved. Next, the data is rebuilt on the new logical drive. During this process the array isin the rebuild state and therefore not redundant.
