In Figure 1, the last two MIH
records specify IOTIMING=00:00 and TIME=00:00. These specifications
cancel MIH or I/O timing processing for the device numbers on the
associated DEV keyword. Similarly, you can cancel hot I/O processing
by specifying:
HOTIO DVTHRSH=0Note: For 3800 devices, the default of 3 minutes for the MIH interval
might not be sufficient. The recommended MIH interval for a 3800 is
5 minutes.
