The Idle State
This state is characterized by the fact that the redundant information of the array drive has never
been entirely created. The array drive is in this state after its first configuration. Should an error
occur while the array is in the build state, the array returns to the idle state Exception: if during
build mode the dedicated drive of a RAID 4 array drive fails, the state changes to
fail .
Figure 98. The Idle State
The Build / Rebuild State
After the array drive has been configured for the first time, and the build process has begun the
array drive assumes the build state. While the array drive is in the build state, redundancy
information is calculated and stored to the components of the array drive.
The disk array will assume the rebuild state after the automatic activation of a hot fix drive or after
a manual replacement (hot plug). The data and the redundant information are reconstructed and
stored to the new drive.
While in the build and rebuild states, the array drive is not redundant.
You can monitor the progress of the array build/rebuild by clicking the right mouse button on the
host drive and then selecting progress information.
✏
NOTE
User traffic on an array drive that is in the build/rebuild state, slows down the build/rebuild
process.
