Minimum Disk Requirement for Different RAID Levels
Express Wizard Only - Assign a Hot Spare
A hot spare is an unused backup physical disk that can be used to rebuild data
from a redundant virtual disk. A hot spare can be used only with a redundant
RAID level. Hot spares also have requirements for physical disk size. The hot
spare must be as big as or bigger than the smallest physical disk included in
the virtual disk. If the RAID level and physical disk availability do not meet
these requirements, a hot spare will not be assigned.
To assign a hot spare to the virtual disk:
1 Select the Assign a Hot Spare Disk check box or leave the check box clear.
2 Click Next to continue with the following section.
