Event Notifications; Power-On Self-Test; Notification Levels - IBM Storwize V7000 Unified Problem Determination Manual

Event notifications

The SAN Volume Controller product can use Simple Network Management
Protocol (SNMP) traps, syslog messages, emails and Call Homes notify you and
the IBM(r) Remote Technical Support Center when significant events are detected.
Any combination of these notification methods can be used simultaneously.
Notifications are normally sent immediately after an event is raised. However,
there are some events that might occur because of service actions that are being
performed. If a recommended service action is active, these events are notified only
if they are still unfixed when the service action completes.
Only events recorded in the event log can be notified. Most CLI messages in
response to some CLI commands are not recorded in the event log so do not cause
an event notification.
Table 36 describes the levels of event notifications.

Power-on self-test

When you turn on the system, the file modules and the control enclosure node
canisters perform self-tests.
A series of tests is performed to check the operation of components and some of
the options that have been installed when the units are first turned on. This series
of tests is called the power-on self-test (POST).
Description
Critical notification is sent to indicate a problem that must be
corrected as soon as possible.
This notification indicates a serious problem with the Storwize
V7000 Unified. For example, the event that is being reported could
indicate a loss of redundancy in the system, and it is possible that
another failure could result in loss of access to data. The most
typical reason that this type of notification is sent is because of a
hardware failure, but some configuration errors or fabric errors also
are included in this notification level. Critical notifications can be
configured to be sent as a Call Home email to the IBM Support
Center.
A warning notification is sent to indicate a problem or unexpected
condition with the Storwize V7000 Unified. Always immediately
investigate this type of notification to determine the effect that it
might have on your operation, and make any necessary corrections.
A warning notification does not require any replacement parts and
therefore should not require IBM Support Center involvement. The
allocation of notification type Warning does not imply that the
event is less serious than one that has notification level Critical.
An informational notification is sent to indicate that an expected
event has occurred: for example, a FlashCopy operation has
completed. No remedial action is required when these notifications
are sent.
