C Note If system power is turned off midway through array initialization the process will continue from its point of interruption when power returns Note In a RAID 5 spare array the disk in the TOP drive carrier is the hot spare initially And disk status indicator of the hot spare one will be shown amber for notification But after disk hot swapping the hot spare disk will be changed For example when hot swap disk 3 then the top disk disk 1 will be auto rebuilt If you plug disk 3 afterward disk 3 will be the new hot spare disk it s no longer the TOP disk It can be recognized by disk status indicator Disk 1 default hot spare disk Disk2 Disk3 Disk4 Hooegoocooe 00 ob000g000a HOoOoge cee o0 ee00o0o0e ga OOO0 000 C000 C2000 0000 QOO0OO0OOO00 00000000 QO000 00000 00000000 qeoooocoooo0o0000ogoa User s Manual Removing replacing a drive What if a disk fails If a disk drive fails the disk status indicator of the disk carrier will light red and the alarm will sound When this happens you should replace the failed disk P Note The failure or removal of a single drive in a RAIDS array will not lead to failure of the array The failure or removal of a single drive in a RAIDO array will lead to loss of all data on the array and the entire array must be re initialized Mote There is no need to immediately replace a failed disk in a RAID 5 spare array The hot spare disk will be brou
