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 whether 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, including an IBMFlashCopy operation completes.
