089

Explanation
A paging I/O operation for the auxiliary storage
manager (ASM) resulted in a permanent I/O error caused by either hardware
or software problems.

System action
If the I/O error occurred during a read operation,
the system writes a logrec data set error record for abend X'089'.
The system then abnormally ends the task that required the page with
abend code X'028'.
If the I/O error occurred during
a write operation, ASM retries the write to a different location in
the page data set. ASM also writes a logrec data set error record.
If
the I/O error was caused by hardware problems, logrec data set may
contain a second error record, an outboard record (OBR) for the I/O
error.

System programmer response
For a hardware problem, contact hardware
support. Otherwise, search problem reporting data bases for a fix
for the problem. If no fix exists, contact the IBM® Support Center.
