Description Redundancy degraded.
Severity Warning / Non-critical
Cause and Action Cause: One or more of the enclosure components has failed.
For example, a fan or power supply may have failed. Although the enclosure is currently operational, the
failure of additional components could cause the enclosure to fail.
Action: Identify and replace the failed component. To identify the failed component, select the enclosure
in the tree view and click the Health subtab. Any failed component is identified with a red X on the
enclosures Health subtab. Alternatively, you can select the Storage object and click the Health subtab.
The controller status displayed on the Health subtab indicates whether a controller has a Failed or
Degraded component.
See the enclosure documentation for information on replacing enclosure components and for other
diagnostic information.

Description
Redundancy lost.
Severity Warning / Non-critical
Cause and Action Cause: A virtual disk or an enclosure has lost data redundancy. In the case of a virtual disk, one or more
physical disks included in the virtual disk have failed. Due to the failed physical disk or disks, the virtual
disk is no longer maintaining redundant (mirrored or parity) data. The failure of an additional physical
disk results in lost data. In the case of an enclosure, more than one enclosure component has failed. For
example, the enclosure may have suffered the loss of all fans or all power supplies.
Action: Identify and replace the failed components. To identify the failed component, select the Storage
object and click the Health subtab. The controller status displayed on the Health subtab indicates
whether a controller has a Failed or Degraded component.
Click the controller that displays a Warning or Failed status. This action displays the controller
Health subtab which displays the status of the individual controller components. Continue clicking the
components with a Warning or Health status until you identify the failed component.
See the online help for more information. See the enclosure documentation for information on replacing
enclosure components and for other diagnostic information.
