HOTIO ON DASD RATE DEFAULT<br />

HOTIO ON 028E RATE 00124<br />

HOTIO ON 0280-028F RATE 00032<br />

Ready;<br />

This response tells you that all devices in the range X'0280' to X'028F' have a hot<br />

I/O rate of 32 (except for the device at X'028E', which has a hot I/O rate of 124,<br />

<strong>and</strong> device X'028F', which has turned off hot I/O detection) <strong>and</strong> all DASD devices<br />

have the default hot I/O rate of 16. Again, if device X'028F' is a DASD device, then<br />

your last SET HOTIO comm<strong>and</strong> (which turned off hot I/O detection for device<br />

X'028F') will override your previous comm<strong>and</strong> (SET HOTIO DASD DEFAULT),<br />

causing all DASD devices have the default hot I/O rate of 16, except for the DASD<br />

at X'028F' which is no longer detecting interrupts.<br />

H<strong>CP</strong>6816E Hot I/O rates are being controlled by<br />

HCD.<br />
