Format
The Format command performs a low-level formatting of the array disk. To format the
array disk, perform the following steps:
1. Right-click the disk that you want to format.
2. Click Format.
The right pane shows the status of the format. The status displays Formatting
until the operation is finished.
Rebuild
The Rebuild command is enabled only when a disk is failed. You can rebuild only on
failed disks in redundant arrays (RAID-1 or RAID-5) by performing the following steps:
1. Right-click the failed disk that you want to rebuild.
2. Click Rebuild.
In the right pane, the status of the disk is Rebuilding and a progress bar shows
the percentage of completion.
Assign Global Hotspare
A hot spare is an unused backup disk that is part of the array group. Hot spares remain
in standby mode. When an array disk in a virtual disk fails, the assigned hot spare will
be activated to replace the failed array disk without interrupting the system or requir-
ing your intervention.
