reported by I/O Processor firmware. When this error counter is active, the
error count is decremented by 1 every 15 minutes, but only if the I/O
Processor has not been reset three times by background maintenance. If
the threshold is exceeded, a MAJOR alarm is raised. Execute a demand
reset by entering reset io-processor and refer to the repair procedures for
Test # 704.
