IBM Storwize V7000, Problem Determination Manual

Page: 47 / 314

Within the Storwize V7000 Unified system, the system Health Status is based on a
set of pre-defined 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.
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.
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.
To resolve the overall health status indicators, perform the following steps:
1.
Log on to the management GUI.
2. Navigate to Monitoring > System Details .
3. From the System Details page, use the navigation tree on the left to display the
hardware components of the system.
The navigation reflects the overall hardware layout of the system. The structure
begins with the overall cluster host name. Under the cluster host name are the
subcomponent areas of the system in which the interface nodes reflect the file
module components, and the enclosure number represents the storage system.
a. Expand the interface nodes to display the two individual file modules that
are represented by the host names
mgmt001st001
and
mgmt002st001
. Expand
each of these file modules to display further details.
For any critical or warning level events, the corresponding hardware reflects
the status with a small red circle or yellow triangle next to the
corresponding device.
b. Navigate to the status by expanding the
mgmt00 x st001
system that shows a
problem.
c. Select Status to produce a list of statuses.
4. Expand any mgmt00 x st001 subcomponent that shows a critical or warning event
indication and select Status .
a. Review the Sensor column and the Level column for Critcal Error , Major
Warning , or Minor Warning items.
If the problem that caused the
Level
item is resolved, right-click the event
and select the
Mark Event as Resolved
action.
b. Follow the online instructions to complete the change.
c.
Review the status list for the other events that might cause the Health
Status to be red or yellow.
