The autoloader returns error details to the host with the following flags.
Each flag is cleared to zero by the following events.
- Autoloader is restarted
- Autoloader is restored by a recovery operation

in Table 8.4.4.2. The three types are:
"I" (Information). Information to the user
"W" (Warning). Advises the user to perform specific actions. The autoloader
performance does not decrease or is there danger of data loss.
"C" (Critical). State requiring an immediate response.
