When a significant change in status is detected, an event
is logged in the event log.
Error data
Events are classified as either
alerts or messages:
- An alert is logged when the event requires some action. Some
alerts have an associated error code that defines the service action
that is required. The service actions are automated through the fix
procedures. If the alert does not have an error code, the alert represents
an unexpected change in state. This situation must be investigated
to see if it is expected or represents a failure. Investigate an alert
and resolve it as soon as it is reported.
- A message is logged when a change that is expected is reported,
for instance, an IBM FlashCopy® operation completes.
