Hot Spare Protection Policy
The Set Hot Spare Protection Policy task allows you to set or modify the number of hot spares to be assigned to the virtual disks.
After you set the number of assigned hot spares, any deviation from the protection policy threshold triggers an alert based on the severity
level you set.

Storage Component Severity
Component status is indicated by the severity. A component with a Warning or Critical/Failure status requires immediate attention to
avoid data loss, if possible. The status of the component indicates the combined status of the components and its lower-level objects.
It may be useful to review the Alert Log for events indicating why a component has a Warning or Critical status.
Table 2. Component Severity
Severity Component Status
Normal/OK — The component is working as expected.
Warning/Non-critical — A probe or other monitoring device has
detected a reading for the component that is above or below the
acceptable level. The component may still be functioning, but it
could fail. The component may also be functioning in an impaired
state. Data loss is possible.
Critical/Failure/Error/Fatal — The component has either failed
or failure is imminent. The component requires immediate attention
and may need to be replaced. Data loss may have occurred.

The Information/Configuration page displays information regarding the storage component. These properties include details such as
the number of connectors (channels or ports) on a controller or the Enclosure Management Modules (EMM) firmware version.
The State and Progress properties display the current activity of a component. For example, an offline physical disk displays the Offline
status while the Progress property displays how close to completion an operation (such as a rebuild) is.
The following sections describe the properties for each component:
• Storage Information And Global Tasks
