11 00 Unrecovered read error A read from tape has failed. This is probably due to bad
media, but may be hardware-related.
Action: 1. Terminate the current I/O and return the appropriate
error.
2. Send a console message that an unrecovered error on
write has occurred.
3. Determine whether the error is deferred, and report
the last successful operation and the failed operation
to the calling application.
4. Log the error and all recovery actions in the system
log.
Recovery action is as follows:
1. Use Log Sense to find the age and state of the tape
and the drive. Based on this, ask the user to clean the
drive or replace the tape.
2. If the fault is drive-related, ask the user to retry the
operation after the drive has been cleaned.
3. If the fault is with the media, prompt the user to back
up the data to a new tape, restart the application and
discard the current tape.
