ICP RAID Console initialization build as "Non-destructive", any data present on the drives being initialized is destroyed. However, re-initialization of this RAID array is Non-destructive. Figure 10-48. Progress Information: Non-destructive Array Build 10.4.1.2 Host Drive Statuses The Select Host Drive screen displays a status for each configured host drive (for example, the RAID 1 array drive in Figure 10-47 has a status of build). Definitions for all states are provided below. Idle State The idle state is characterized by the fact that the redundant information of the disk array has never been entirely created. The disk array is in this state after its first configuration and until you quit ICPCON. Should an error occur while the array is in the build state, the array returns to idle. The exception is that if during build mode the dedicated drive of RAID 4 fails, the mode changes to fail. Build State After the disk array has been configured for the first time, it assumes the build state. While the array is in the build state, redundancy information is calculated and stored to the hard disks of the array. Ready State The disk array is fully operational when in the ready state. All redundant information is present, for example, a hard disk can fail without impairing the functionality of the disk array. This is the normal state of a disk array. The state ready/expand indicates that the RAID level and/or capacity are currently migrated/expanded. Fail State The disk array changes to the fail state whenever a logical drive fails. Redundancy information is still present, thus allowing the remaining hard disks to continue working. This state should be eliminated as soon as possible by replacing the defective hard disk.
