Software Installation and User’s Guide183ICP RAID Navigatordata availability. Of course a hot fix drive is not mandatory. If you control the array driveat regular intervals and immediately replace a defective hard disk (by shutting down thesystem or using a hot fix), you can minimize the risk of data loss.11.5.16 Remove Hot FixClick the right mouse button on the array drive icon.This option opens a box showing available hot fix drives. Select the hot fix drive you wantto remove from the array drive and then confirm your selection. You can remove any poolhot fix drives or a private hot fix drive from the selected array drive.11.5.17 Hot Fix Pool AccessClick the right mouse button on the array drive icon.Enable or disable the access of an array drive to the pool hot fix of hot fix drives. If theaccess is enabled this means that if a member of an array drive fails, a drive can be takenfrom the hot fix pool and built automatically into the array drive. To be able to activatethis feature, there must be suitable logical drives in the hot fix pool. You can add drives tothe hot fix pool using the function Add Hot Fix Drive. By doing so, the hot fix pool accessfor this specific array drive is activated automatically. For all other arrays drive you mustactivate the access manually.11.5.18 Add RAID 1 Component (Mirror a Drive)Click the right mouse button on the logical drive icon.This function allows you to add to a logical drive which is a member of an array drive,another logical drive as a mirror drive (RAID 1).Example: You have configured an array drive with 4 logical drives. One logical drive hasfailed and the array drive went into the fail state. Another failure would cause data loss.Unfortunately, you find another logical drive that is likely to fail (for example, you hear astrange noise from it, or it's grown defect counter explodes). If you initiate a hot plug it islikely that the critical logical drive will also fail. To avoid that problem, mirror a new goodlogical drive to the critical one. When the copying is finished, remove the critical logicaldrive and carry out a hot plug procedure.
