Health status and recovery
Use this information to review the outstanding issues that cause the Health Status
indicator at the bottom of all management GUI panels to be red (critical errors) or
yellow (warnings or degradations).

Before you begin

Use this procedure after you resolve the events from the Monitoring > Events
page to resolve the overall system health status indicators.
About this task
Within the Storwize V7000 Unified system, the system Health Status is based on a
set of predefined software and hardware health status sensors that are reflected in
the System Details page under the Status section for the corresponding logical host
name.
For storage problems, resolve events and health status by running the
recommended repair action or actions from the Block tab of Monitoring > Events.
For file module problems, the software and hardware sensors are different. Some
of the sensors are automatic and actively reflect the current status of the system;
whereas, some of the sensors, such as the hardware sensors, require a reset after
the service actions are completed.
Note: For the file modules, the System Details page and sensors are separate from
the events. Events that are displayed in the log might be reflected within a
corresponding sensor with the System Details > Status indicator for the failing
host name. However, be aware that resolving events and resetting the
corresponding sensor changes the health status of the system but does not clear the
corresponding event from the event log.
This topic instructs you where to go to view the information that is displayed, how
to check the status of the various sensors, and how to manually close out sensor
events. By performing these tasks, you ensure that the overall Health Status
reflects the current system health.
To resolve the overall health status indicators, perform the following steps:
