Event notifications
The Storwize V7000 product can use Simple Network Management Protocol
(SNMP) traps, syslog messages, emails and Call Homes to notify you and IBM(r)
Remote Technical Support 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 26 describes the levels of event notifications.
Table 26. Notification levels
Notification level Description
Error Error notification is sent to indicate a problem that must be
corrected as soon as possible.
This notification indicates a serious problem with the system. 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. Error notifications can be configured to be sent as
a Call Home to the IBM Remote Technical Support.
Warning A warning notification is sent to indicate a problem or unexpected
condition with the system. 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 Error.
Information 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.
Power-on self-test
When you turn on the system, the 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).
If a critical failure is detected during the POST, the software is not loaded and the
fault LED is illuminated. To determine if there is a POST error on a canister, go to
“Procedure: Understanding the system status using the LEDs” on page 54.
