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 FlashCopy® operation completes.
