Event ID — 2123
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.
